1N5918BP/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5918BP/TR12 is a glass-encapsulated Zener diode with a nominal voltage of 5.1 V and a maximum power dissipation of 1.5 W. It features a 5% voltage tolerance, a maximum dynamic impedance of 4 Ohms at a test current of 73.5 mA, and a maximum reverse leakage current of 5 µA at 5.0 V. The device operates within a temperature range of -65 °C to +175 °C and utilizes a DO-204AL axial lead package.

Single Zener Diodes Feature Summary

• Hermetically sealed glass body construction for high reliability
• Metallurgically enhanced internal contact design for lower thermal resistance
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard

Single Zener Diodes Applications

• Voltage regulation over broad operating currents and temperatures
• High reliability applications requiring hermetic sealing
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official documentation to confirm RoHS compliance status and tape-and-reel packaging specifications. Ensure that the ordering nomenclature matches the required tolerance level and screening standards before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 5.1 V reference with 5% tolerance is required in an axial lead package. Consider the 1.5 W power rating and wide temperature range for demanding environments. Verify compatibility with existing board layouts due to the DO-204AL dimensions.

Single Zener Diodes Part Context

This part belongs to the 1N5913BG through 1N5956BG series of 1.5 Watt Glass Zener Diodes. The series provides voltage regulation from 3.3 V to 200 V with various tolerance options. The 'P' suffix indicates an optional plastic body construction, while the 'TR12' suffix denotes tape and reel packaging.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 5.1 V Zener diodes in the DO-41 package with similar power ratings. Verify electrical characteristics such as dynamic impedance and leakage current match the original requirements.
