TZX3V0B-TR

Single Zener Diodes Overview

The TZX3V0B-TR is a single-channel small signal Zener diode from the Vishay TZX series, housed in a DO-35 axial through-hole package. It provides a nominal Zener voltage range of 2.9 V to 3.1 V at a test current of 5 mA. The device supports a maximum power dissipation of 500 mW and features a tight tolerance band. Key electrical characteristics include a maximum reverse leakage current of 6 µA at 0.5 V and a dynamic resistance of 100 Ω measured 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
• Reference voltage generation
• Overvoltage protection circuits

Single Zener Diodes Procurement Notes

Verify the specific suffix 'B' indicates the required ±2% tolerance band during procurement. Confirm the '-TR' designation aligns with reel packaging requirements. Ensure the DO-35 lead spacing matches the target PCB footprint. Validate that the 500 mW thermal rating accommodates the application's ambient temperature conditions.

Single Zener Diodes Selection Notes

Select this component when a stable reference near 3 V is required with tight voltage accuracy. The DO-35 package is suitable for applications requiring robust mechanical mounting or manual soldering. Consider the 100 Ω dynamic resistance for load regulation requirements. Verify that the 5 mA test current fits within the available bias current budget of the circuit design.

Single Zener Diodes Part Context

This part belongs to the Vishay TZX series of small signal Zener diodes. The series covers a wide voltage range from 2.4 V to 36 V. The TZX3V0B-TR specifically targets low-voltage regulation needs. The product line is characterized by high reliability and consistent manufacturing tolerances across the entire voltage spectrum.

Single Zener Diodes Replacement Considerations

Cross-reference other manufacturers offering DO-35 packaged Zener diodes with a 3 V nominal voltage and similar 500 mW power ratings. Ensure any substitute maintains the same 2.9 V to 3.1 V tolerance window and comparable dynamic resistance specifications.
