KDZVTR20B

Single Zener Diodes Overview

The KDZVTR20B is a single Zener diode manufactured by ROHM Semiconductor, designed for constant voltage control applications. It features a PMDU (SOD-123FL) surface-mount package with dimensions of 3.5x1.6 mm and a height of 0.9 mm. The device has a typical Zener voltage of 20.82 V, with a range from 20 V to 22.4 V at a test current of 20 mA. It dissipates up to 1000 mW of power and operates within a junction temperature range of -55°C to +150°C. The component is supplied in taping packaging with a minimum order quantity of 3000 units.

Single Zener Diodes Feature Summary

• High ESD tolerance capability

Single Zener Diodes Applications

• Constant voltage control circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape and reel packaging configuration. Confirm RoHS compliance status through official documentation. Ensure the application does not involve automotive equipment as this standard-grade product is explicitly not recommended for such use. Check long-term supply plans for availability assurance.

Single Zener Diodes Selection Notes

Select this component for general-purpose voltage regulation where high ESD protection is required. The PMDU package offers a compact footprint suitable for space-constrained designs. Consider the 20.82 V nominal voltage and 20 mA test current when designing biasing networks. Avoid automotive applications due to explicit manufacturer restrictions on this standard-grade series.

Single Zener Diodes Part Context

This part belongs to the KDZV 30B series of Zener diodes from ROHM Semiconductor. It is classified under Diodes & Rectifiers. The device is marked as a recommended product for new designs. It shares the PMDU package code with other variants in the family but differs in voltage specifications and test currents.
