ICE3BR0665J

ICE3BR0665J Overview

ICE3BR0665J is a Infineon Technologies 650 V integrated CoolMOS and current-mode flyback controller for offline power supplies supplied in 8-pin PG-DIP-8. This page uses the exact orderable code because package, grade, temperature and option suffixes can change compatibility.

Key Technical Specifications

Package and Ordering Notes

The listed package is 8-pin PG-DIP-8 with 8 pins, leads, lands or contacts. The featured image is a generic package illustration for form-factor identification and is not an actual date-code or lot photograph. Lifecycle is recorded as NRND; confirm current factory support and last-time-buy constraints before design-in.

Sourcing Guidance

ICE3BR0665J is not recommended for new designs. Confirm current availability and qualify a current-generation alternative before design-in.

For an accurate quotation, include the full MPN, target quantity, acceptable date-code range, packaging format and destination. Icearth can help review traceability documents, label photos and electrical/package alignment before order placement.

Manufacturer Documentation

Technical values were checked against Infineon Technologies documentation. Use the linked datasheet as the controlling source and re-check revisions before PCB release or firmware qualification.

ICE3BR0665J selection and design context

ICE3BR0665J is cataloged as a AC-DC Power Switch in the CoolSET ICE3BR family. Its recorded function is 650 V integrated CoolMOS and current-mode flyback controller for offline power supplies. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.

• MOSFET Voltage: 650 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
• MOSFET RDS(on): 0.65 Ω typical. Confirm the value and its datasheet test conditions for the exact ordering suffix.
• Switching Frequency: 65 kHz. Confirm system timing margin and the test conditions attached to the published limit.
• Controller: Current-mode flyback PWM. Confirm the value and its datasheet test conditions for the exact ordering suffix.

Application and qualification considerations

When evaluating this power device, confirm input range, output requirements, switching frequency, compensation, current limit, efficiency and thermal design. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.

Procurement checks for ICE3BR0665J

The recorded package is 8-pin PG-DIP-8, the temperature range is -25°C to +130°C junction, and the lifecycle status is NRND as of 2026-07-24. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.

ICE3BR0665J FAQ

How ICE3BR0665J differs from related orderable parts

ICE3BR0665J belongs to the CoolSET ICE3BR family. Compared with ICE3BR1765J, the recorded differences include functional description: 650 V integrated CoolMOS and current-mode flyback controller for offline power supplies versus 650 V integrated CoolMOS and current-mode flyback controller for low-power offline supplies; MOSFET RDS(on): 0.65 Ω typical, a lower recorded value than 1.7 Ω typical; and Output Power Class: Approximately 41 W maximum, application dependent, a higher recorded value than Approximately 25 W maximum, application dependent. A shared family name does not establish pin, firmware or qualification compatibility.

For an RFQ or AVL review, quote the complete ICE3BR0665J code and verify the manufacturer ordering table, package drawing, packing method and revision. The related numbers above are comparison references, not declared drop-in replacements.

Exact order-code identity for ICE3BR0665J

For BOM, label, AVL and RFQ matching, preserve these visible code segments: opening alphabetic sequence ICE; middle numeric sequence three; middle alphabetic sequence BR; middle numeric sequence zero six six five; and terminal alphabetic sequence J. The nearest published comparison codes are ICE3BR1765J. Compare every segment because a changed character can identify a different density, voltage, package, temperature, qualification or packing option.

Do not shorten the requested code to CoolSET ICE3BR or remove its terminal characters. Ask the supplier to reproduce the complete code on the quotation and provide label or traceability evidence when exact suffix matching is mandatory.

ICE3BR0665J specification interpretation

The following notes interpret the recorded values for this exact orderable code. They are intended to make model-to-model differences visible during engineering and procurement review; the manufacturer datasheet remains the controlling source.

• MOSFET Voltage: The recorded value is 650 V, expressed in words as six hundred fifty V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
• MOSFET RDS(on): The recorded value is 0.65 Ω typical, expressed in words as zero point six five Ω typical. Confirm the value and its datasheet test conditions for the exact ordering suffix. The comparison record for ICE3BR1765J lists 1.7 Ω typical; this page therefore preserves 0.65 Ω typical as the value associated with ICE3BR0665J.
• Switching Frequency: The recorded value is 65 kHz, expressed in words as sixty five kHz. Confirm system timing margin and the test conditions attached to the published limit.
• Controller: The recorded value is Current-mode flyback PWM. Confirm the value and its datasheet test conditions for the exact ordering suffix.
• Output Power Class: The recorded value is Approximately 41 W maximum, application dependent, expressed in words as Approximately forty one W maximum, application dependent. Check steady-state, transient and thermal margin in the intended operating mode. The comparison record for ICE3BR1765J lists Approximately 25 W maximum, application dependent; this page therefore preserves Approximately 41 W maximum, application dependent as the value associated with ICE3BR0665J.
