Package and Ordering Notes
The listed package is SOD-523 (historically verified) with 2 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 Last Time Buy; confirm current factory support and last-time-buy constraints before design-in.
Sourcing Guidance
Earlier official-source review confirmed RB521S-30TE61; the original release was blocked only because a verified package illustration was unavailable. Earlier blocker: ROHM confirms Last Time Buy order code RB521S-30TE61, but the repository lacks an accurate SOD-523 package illustration; no approximate package image was substituted. Do not infer electrical, mechanical, lifecycle or suffix data from a similar model. Request traceability and revision-controlled documentation for RB521S-30TE61 before procurement or design approval.
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.
Documentation and Source Status
No matching public record was found on the manufacturer site or the approved second-tier sources (DigiKey, Mouser, JLCPCB and LCSC) at the verification date. Unavailable fields are stated as unavailable; the scheduled MPN is preserved and no specification, lifecycle, package or ordering suffix is inferred.

RB521S-30 FAQ
What is known about RB521S-30?
RB521S-30 is retained as an exact scheduled component record attributed to ROHM Semiconductor. The earlier official-source review confirmed the orderable code RB521S-30TE61. No unsupported electrical or mechanical values have been added.
Why are detailed specifications unavailable for RB521S-30?
An exact manufacturer product record plus datasheet was not available, and the approved DigiKey, Mouser, JLCPCB and LCSC checks did not yield an automatically usable exact product detail page on 2026-08-04. Similar models were not used as substitutes.
What package does RB521S-30 use?
RB521S-30TE61 was previously verified in SOD-523 (historically verified). The displayed image is deliberately neutral because a verified matching package illustration is not available in the repository.
What is the lifecycle status of RB521S-30?
RB521S-30TE61 was recorded as Last Time Buy during the earlier official-source review. Reconfirm the current status before sourcing because lifecycle information can change.
What should be checked before sourcing RB521S-30?
Quote RB521S-30TE61 exactly where that ordering code is known. Require manufacturer traceability, package marking, packing format, date code, lifecycle status and a revision-controlled datasheet before procurement or design approval.
