RD3.3UM-T1-AT

Single Zener Diodes Overview

The RD3.3UM-T1-AT is a single Zener diode manufactured by Renesas Electronics Corporation, classified under discrete semiconductor products and specifically within the Zener diode category. It is housed in a 2-pin ultra-super mini mold package, designed for compact surface-mount applications. The device operates with a maximum junction temperature of 150°C and supports a peak pulse power rating of 85W. This component serves as a voltage reference or protection element in electronic circuits, leveraging its small form factor to integrate efficiently into space-constrained designs while maintaining reliable performance under specified thermal and electrical conditions.

Single Zener Diodes Feature Summary

• Compact physical footprint utilizing an ultra-super mini mold package for space-efficient integration
• High thermal resilience capable of operating at junction temperatures up to 150°C
• Robust transient handling capability with a peak pulse power rating of 85W

Single Zener Diodes Applications

• Voltage regulation in low-power consumer electronics
• Transient voltage suppression in signal lines
• Reference voltage generation in compact sensor interfaces

Single Zener Diodes Procurement Notes

Verify the specific suffix (T1-AT) against official Renesas documentation to confirm exact binning and tape-and-reel specifications. Ensure compatibility with standard SMD reflow profiles given the 150°C junction limit. Cross-reference RoHS compliance status through current datasheets, as manufacturing updates may affect material declarations. Confirm availability status directly with authorized distributors, as component lifecycle stages can change without immediate public notice.

Single Zener Diodes Selection Notes

Select this component when board real estate is limited due to its ultra-super mini mold packaging. Consider the 85W peak pulse rating for applications requiring moderate transient protection rather than high-energy TVS solutions. The 150°C junction temperature suitability makes it appropriate for environments where ambient heat is elevated but does not exceed safe operating limits. Validate that the Zener voltage aligns precisely with circuit requirements before finalizing the design.

Single Zener Diodes Part Context

This part belongs to Renesas' discrete semiconductor portfolio, specifically the Zener diode segment. While Renesas is widely recognized for microcontrollers and power management ICs, this component represents their offering in passive-like protection devices. It complements larger system solutions by providing localized voltage clamping or referencing in compact modules, fitting into the broader ecosystem of automotive and industrial control hardware where reliability and size are critical constraints.

Single Zener Diodes Replacement Considerations

Publicly confirmed substitute part numbers for the RD3.3UM-T1-AT are not available in the provided source data. Engineers should consult official Renesas replacement guides or contact technical support for validated cross-references. Generic equivalents may exist but require rigorous qualification to ensure matching package dimensions, thermal characteristics, and electrical tolerances.
