HZS22-1TD-E

Single Zener Diodes Overview

The HZS22-1TD-E is a single Zener diode manufactured by Renesas Electronics Corporation. It functions as a unidirectional voltage regulator diode constructed from silicon material. The component is rated for a power dissipation of 0.4W and features a breakdown voltage of 21.4V. It is housed in the DO-34 (MHD) axial leaded package, which provides two pins for circuit integration. This device is designed for stable voltage regulation applications within specified thermal limits.

Single Zener Diodes Feature Summary

• Unidirectional voltage regulation capability
• Silicon-based construction for reliability
• Axial leaded package design for through-hole mounting

Single Zener Diodes Applications

• Voltage reference circuits
• Overvoltage protection stages
• General-purpose voltage regulation

Single Zener Diodes Procurement Notes

Verify the specific suffix TD-E against the manufacturer's current datasheet to confirm pinout orientation and compliance status. Ensure the DO-34 package dimensions match the target PCB footprint requirements. Confirm RoHS3 compliance documentation is available for regulatory adherence in the intended market.

Single Zener Diodes Selection Notes

Select this component when a 21.4V Zener voltage with 0.4W power handling is required in an axial package. Compare thermal resistance characteristics against similar DO-34 devices if high ambient temperatures are expected. Validate that the unidirectional nature aligns with the circuit's polarity constraints.

Single Zener Diodes Part Context

This part belongs to the HZS22 series of Zener diodes from Renesas. The series offers various voltage ratings within the same mechanical form factor. The HZS22-1 variant specifically denotes the 21.4V breakdown voltage option within this product line.

Single Zener Diodes Replacement Considerations

Check for direct cross-reference part numbers from other manufacturers offering identical 21.4V, 0.4W specifications in the DO-34 package. Verify electrical parameter tolerances and thermal performance before substitution.
