Package and Ordering Notes
The listed package is 8-pin SOIC 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
IR2101S is not recommended for new designs. Confirm support for the existing program and qualify a current alternative for new designs.
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.
