TFZVTR22B

Single Zener Diodes Overview

The TFZVTR22B is a single Zener diode manufactured by ROHM Semiconductor, designed for surface-mount applications. It features a nominal Zener voltage of 22 V with a tolerance range of 22.61 V to 23.77 V. The device operates within a power dissipation rating of 500 mW and maintains a maximum reverse leakage current of 200 nA. It utilizes the SOD-323HE-2 package (JEITA SC-108B) and supports an operating temperature range from -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• High-reliability automotive-grade construction compliant with AEC-Q101 standards
• Compact SOD-323HE-2 surface-mount package optimized for space-constrained designs
• Low reverse leakage current characteristics suitable for precision voltage regulation

Single Zener Diodes Applications

• Automotive electronic circuit voltage regulation
• General-purpose voltage reference circuits
• Transient voltage suppression in low-power systems

Single Zener Diodes Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm that the specific ordering code matches the required tape-and-reel packaging format. Ensure design compatibility with the specified thermal management requirements for the SOD-323HE-2 package during high-temperature operation.

Single Zener Diodes Selection Notes

Select this component when a 22 V Zener voltage is required in a compact surface-mount form factor. The 500 mW power rating distinguishes it from lower-power alternatives like the EDZVFHT series. Verify that the 200 nA leakage current meets the specific circuit requirements compared to higher-leakage general-purpose diodes.

Single Zener Diodes Part Context

This part belongs to the TFZV series of Zener diodes from ROHM Semiconductor. The series is characterized by its small plastic mold package and suitability for automotive applications requiring high reliability. It serves as a standard solution for voltage clamping and reference tasks in modern electronics.

Single Zener Diodes Replacement Considerations

TFZVTR24B and TFZVTR27B are available within the same series but offer different nominal voltages. For direct replacement with identical specifications, verify exact voltage tolerance alignment. Other packages such as SOD-523 require footprint redesign.
