TZX8V2A-TR

Single Zener Diodes Overview

The TZX8V2A-TR is a single-channel small signal Zener diode from the Vishay TZX series, housed in a DO-35 (DO-204AH) through-hole package. It provides a nominal Zener voltage range of 7.7 V to 8.1 V at a test current of 5 mA. The device features a maximum power dissipation of 500 mW and operates within a junction temperature range of -65 °C to +175 °C. Electrical characteristics include a maximum reverse leakage current of 1 µA at 6.2 V and a dynamic resistance of 20 Ω at the test current.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise regulation
• Low reverse current level ensuring minimal standby loss
• Very high stability with low noise performance

Single Zener Diodes Applications

• Voltage stabilization

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates taped reel packaging as per the ordering information table. Confirm that the 'A' designation corresponds to the 7.7 V to 8.1 V voltage bin. Ensure the required quantity aligns with the minimum order quantity of 30,000 units per box or 10,000 units per reel specified in the datasheet.

Single Zener Diodes Selection Notes

Select this component when a stable reference voltage near 8 V is required in through-hole designs. The DO-35 package supports lead lengths up to 4 mm for optimal thermal dissipation. Consider the 5 mA test current requirement for biasing circuits and ensure the application stays within the 500 mW power limit at the expected ambient temperature.

Single Zener Diodes Part Context

This part belongs to the Vishay TZX-Series of small signal Zener diodes. The series covers a wide Zener voltage range from 2.4 V to 36 V. These devices are designed for general-purpose voltage regulation applications requiring high stability and low noise characteristics in standard axial leaded packages.

Single Zener Diodes Replacement Considerations

Other parts within the TZX-series with different voltage bins (e.g., TZX8V2B, TZX8V2C) offer similar electrical profiles but different voltage ranges. Cross-referencing requires matching the specific voltage tolerance and package type.
