1N4906A/TR

Overview

The Microchip Technology 1N4906A/TR is a temperature-compensated Zener diode with a nominal voltage of 12.8 V and a tolerance of ±5%. It features a maximum power dissipation of 400 mW and a maximum Zener impedance of 100 Ohms. The device operates within a junction temperature range of -55°C to 100°C and utilizes an axial DO-7 (DO-204AA) through-hole package.

Feature Summary

• Temperature compensated design for stable voltage regulation across varying thermal conditions
• Axial leaded construction suitable for through-hole mounting applications

Applications

• Precision voltage reference circuits requiring thermal stability
• Overvoltage protection in sensitive electronic systems
• Voltage regulator designs utilizing through-hole technology

Procurement Notes

Verify the specific suffix configuration against official Microchip documentation to confirm the reel packaging format associated with the /TR designation. Ensure that the component specifications align with the required thermal and electrical parameters for the intended application environment before finalizing procurement orders.

Selection Notes

Select this component when a stable 12.8 V reference is needed with low temperature drift characteristics. The through-hole DO-7 package facilitates manual assembly or standard PCB mounting processes. Confirm that the 400 mW power rating meets the circuit's thermal dissipation requirements under all operating conditions.

Part Context

This part belongs to the 1N4906 series of temperature-compensated Zener diodes manufactured by Microchip Technology. These devices are engineered to provide consistent voltage regulation despite changes in ambient temperature, distinguishing them from standard Zener diodes which may exhibit higher thermal coefficients.

Replacement Considerations

Consult official Microchip substitution guides for verified equivalents. Cross-reference technical specifications carefully to ensure compatibility with existing circuit designs.
