TZX33B-TAP

Single Zener Diodes Overview

The TZX33B-TAP is a single-channel Zener diode manufactured by Vishay General Semiconductor - Diodes Division. It features a nominal Zener voltage of 33V with a tight tolerance of 2%. The device is designed for through-hole mounting in a DO-35 axial leaded package, measuring 1.7mm in diameter and 3.9mm in length. It supports a maximum power dissipation of 500mW and operates at temperatures up to +175°C. Key electrical characteristics include a test current of 2mA, a maximum Zener impedance of 120Ω, and a maximum reverse leakage current of 1µA.

Single Zener Diodes Feature Summary

• Provides precise voltage regulation with a 2% tolerance on the nominal 33V breakdown voltage.
• Capable of handling high thermal loads with an operating junction temperature reaching +175°C.
• Utilizes a standard DO-35 axial leaded package suitable for reliable through-hole circuit integration.

Single Zener Diodes Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in low-power electronics
• Clamping applications in signal conditioning paths

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TAP' against official Vishay documentation to confirm packaging configuration, as suffixes often denote tape-and-reel quantities or specific handling requirements distinct from bulk packaging. Ensure the component matches the DO-35 form factor and 500mW rating required for the target design constraints before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a highly accurate 33V reference is needed in a through-hole layout. The 2% tolerance offers superior precision compared to standard 5% variants. Consider the 120Ω impedance limit for dynamic load variations and ensure the PCB layout accommodates the axial leads and thermal dissipation needs of the DO-35 package.

Single Zener Diodes Part Context
