BZX55C9V1-TR

Single Zener Diodes Overview

The BZX55C9V1-TR is a single silicon Zener diode from the Vishay BZX55 series, housed in a DO-35 (DO-204AH) axial through-hole package. It provides a nominal Zener voltage of 9.1 V with a tolerance of ±5%. The device operates at a test current of 5 mA and dissipates up to 500 mW. Key electrical parameters include a maximum reverse leakage current of 0.1 µA at 6.8 V, a dynamic resistance of less than 10 Ω, and a temperature coefficient ranging from +0.03 %/K at 25 °C to +0.09 %/K at 150 °C.

Single Zener Diodes Feature Summary

• Very sharp reverse characteristic for precise regulation
• Low reverse current level ensuring minimal power loss
• Very high stability under varying conditions
• Low noise performance suitable for sensitive circuits

Single Zener Diodes Applications

• Voltage stabilization
• Reference voltage generation
• Overvoltage protection
• Clamping applications

Single Zener Diodes Procurement Notes

Verify the specific suffix 'TR' indicates tape-and-reel packaging when ordering. Confirm compliance requirements such as RoHS status against project specifications. Ensure the DO-35 lead spacing matches the target PCB footprint. Validate that the ±5% tolerance aligns with circuit design margins before finalizing procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a stable 9.1 V reference with tight tolerance. Consider the low leakage current for high-impedance circuits. Evaluate the thermal resistance characteristics if operating near maximum power dissipation limits. Compare dynamic resistance values against noise sensitivity requirements of the target application.

Single Zener Diodes Part Context

This part belongs to the BZX55 series of small signal Zener diodes manufactured by Vishay Semiconductors. The series covers a wide voltage range from 2.4 V to 75 V. The BZX55C variant specifically denotes a ±5% tolerance band. These components are designed for general-purpose voltage regulation tasks in compact axial packages.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same family include BZX55B9V1-TR for tighter ±2% tolerance or BZM55C9V1-TR for MELF packaging. Verify pinout compatibility and thermal ratings when substituting across different package types.
