BZX79B2V4

Single Zener Diodes Overview

The BZX79B2V4 is a low-power voltage regulator diode manufactured by Taiwan Semiconductor Corporation. It features a nominal Zener voltage of 2.4 V with a tight tolerance of ±2%. The device is housed in a hermetically sealed DO-35 glass package, suitable for through-hole mounting. It supports a total power dissipation of 500 mW and operates within a temperature range of -65°C to +200°C. The component is designed for applications requiring precise voltage regulation in small signal circuits.

Single Zener Diodes Feature Summary

• Hermetically sealed glass construction ensures long-term reliability and environmental stability.
• Tight voltage tolerance of ±2% provides high precision for sensitive reference applications.
• Wide operating temperature range up to +200°C allows functionality in extreme thermal conditions.

Single Zener Diodes Applications

• Precision voltage reference circuits
• Overvoltage protection stages
• Small signal clipping and clamping

Single Zener Diodes Procurement Notes

Verify the current lifecycle status directly with Taiwan Semiconductor or authorized distributors before design finalization. Confirm RoHS compliance details and specific packaging options such as reel or cut tape availability. Ensure the selected variant matches the required ±2% tolerance specification for your application.

Single Zener Diodes Selection Notes

Select this component when a stable 2.4 V reference is required in a through-hole DO-35 package. Consider the 500 mW power rating and ±2% tolerance against circuit requirements. Evaluate the wide temperature capability if the environment exceeds standard industrial limits compared to lower-grade alternatives.

Single Zener Diodes Part Context

This part belongs to the BZX79B series of low-power Zener diodes from Taiwan Semiconductor. The series offers normalized E24 voltage values with ±2% tolerance. These devices are characterized by their hermetically sealed glass packages and robust performance across a broad temperature spectrum, distinguishing them from standard commercial grade equivalents.

Single Zener Diodes Replacement Considerations

Cross-reference with Nexperia BZX79-B2V4 or similar DO-35 Zener diodes offering 2.4 V nominal voltage and ±2% tolerance. Verify that substitute components match the 500 mW power dissipation and hermetic sealing requirements to ensure mechanical and electrical compatibility.
