CDZFHT2RA5.6B

Single Zener Diodes Overview

The CDZFHT2RA5.6B is a single Zener diode manufactured by Rohm Semiconductor, designed for surface-mount applications in automotive-grade environments compliant with AEC-Q101 standards. It features a nominal Zener voltage of 5.6V with a tight tolerance of ±2.09%, tested at a current of 5mA. The device dissipates up to 100mW and operates within a junction temperature range of -55°C to +150°C. Packaged in the compact VMN2 (SOD-923) format measuring 1.0x0.6mm, it ensures high reliability for voltage regulation tasks.

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix and tape-and-reel quantity against official Rohm documentation before procurement. Confirm that the VMN2 package dimensions align with the target PCB footprint. Ensure compliance with RoHS directives and check for any end-of-life notices or last-time-buy statuses associated with this specific part number variant.

Single Zener Diodes Selection Notes

Select this component when a precise 5.6V reference is required in space-constrained automotive designs. The VMN2 package offers a smaller footprint compared to standard SOD-923 variants. Consider the 100mW power dissipation limit and the ±2.09% voltage tolerance when designing the surrounding circuitry for thermal management and accuracy requirements.

Single Zener Diodes Part Context

This part belongs to the CDZFH series of Zener diodes from Rohm Semiconductor. The series is characterized by its small plastic encapsulation and suitability for high-reliability applications. The CDZFHT2RA5.6B specifically utilizes the VMN2 package code, distinguishing it from other series members that may use larger footprints or different mounting configurations.

Single Zener Diodes Replacement Considerations

The EDZVFH5.6B is listed as a similar specification replacement. Note that the substitute uses an EMD2 (SOD-523) package, which has different physical dimensions than the original VMN2 package. Verify mechanical fit and pin compatibility before substitution.
