1N5915BPE3/TR8

Single Zener Diodes Overview

The Microsemi Corporation 1N5915BPE3/TR8 is a single axial-leaded Zener diode with a nominal voltage of 3.9 V and a maximum power dissipation of 1.5 W. It features a 5% tolerance, a maximum dynamic impedance of 7.5 Ohms, and a reverse leakage current of 25 µA at 1 V. The device operates within a temperature range of -65°C to +175°C and utilizes a DO-41 (DO-204AL) package.

Single Zener Diodes Feature Summary

• Hermetically sealed glass body construction for high reliability
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020
• Inherently radiation hard design
• Flexible axial-lead mounting terminals

Single Zener Diodes Applications

• Voltage regulation over broad operating currents and temperatures
• High-reliability military equivalent screening applications
• Radiation-hardened circuit designs

Single Zener Diodes Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm RoHS compliance status and tolerance level. Confirm that the TR suffix indicates tape and reel packaging as specified in the part nomenclature section. Ensure compatibility with MIL-PRF-19500 screening requirements if applicable to the intended deployment environment.

Single Zener Diodes Selection Notes

Select this component when a precise 3.9 V reference is required in an axial leaded package. The 5% tolerance provides tighter regulation than standard commercial equivalents. Consider the hermetic glass construction for environments requiring superior moisture resistance and radiation hardness compared to plastic encapsulated alternatives.

Single Zener Diodes Part Context

This component belongs to the 1N5913BG through 1N5956BG series of 1.5 watt glass Zener diodes manufactured by Microsemi Corporation. The series covers a wide voltage range from 3.3 V to 200 V. The 'G' suffix denotes the glass casing, while the 'e3' suffix indicates RoHS compliance.

Single Zener Diodes Replacement Considerations

Equivalent parts include other 1N5915 variants such as 1N5915AG or 1N5915CPE3/TR8, provided the tolerance and package specifications align with the design requirements.
