1N5952BG

Single Zener Diodes Overview

The Microsemi 1N5952BG is a silicon unidirectional Zener diode with a nominal voltage of 130 V and a 5% tolerance. It operates in a DO-41 (DO-204AL) glass package, providing a steady-state power dissipation of 1.5 W at a lead temperature of 85 °C or lower. The device features a maximum dynamic impedance of 450 Ω and a reverse current of 5 µA at 1.0 V. It supports an operating junction temperature range from -65 °C to +175 °C.

Single Zener Diodes Feature Summary

• Hermetically sealed glass body construction with metallurgically enhanced internal contacts for high reliability.
• Inherently radiation hard as described in Microsemi MicroNote 050.
• Non-sensitive to electrostatic discharge per MIL-STD-750 method 1020.

Single Zener Diodes Applications

• Voltage regulation over a broad range of operating currents and temperatures.
• High density circuit designs requiring low parasitic characteristics.
• Applications demanding hermetic sealing and high reliability screening.

Single Zener Diodes Procurement Notes

Verify the specific suffix requirements against the official datasheet nomenclature to ensure correct tolerance and compliance levels. Confirm whether RoHS compliant versions are required, as commercial grades may differ from standard military equivalent screening options. Ensure sourcing aligns with the manufacturer's specified part numbering conventions.

Single Zener Diodes Selection Notes

Select this component when a 130 V breakdown voltage with tight 5% tolerance is necessary. The DO-41 glass package offers superior thermal resistance compared to plastic equivalents. Consider the available military screening levels if the application requires adherence to MIL-PRF-19500 standards for critical systems.

Single Zener Diodes Part Context

This device belongs to the 1N5913BG through 1N5956BG series of axial-leaded Zener diodes. The series covers a voltage range from 3.3 V to 200 V. The 'G' suffix specifically denotes the glass encapsulated version, which provides hermetic-sealed qualities and higher rated temperatures compared to the plastic-body constructions available in the same JEDEC number series.

Single Zener Diodes Replacement Considerations

Equivalent plastic body versions exist under the 1N5913BP – 1N5956BP series. Surface mount alternatives include the 1N5913BUR-1 through 1N5956BUR-1 MELF packages. Verify that replacement parts match the required hermetic sealing and thermal performance specifications.

Single Zener Diodes FAQ

What is the maximum operating junction temperature?

The maximum operating junction temperature is +175 °C.

How is the polarity indicated on the device?

Polarity is indicated by a band on the cathode end. For Zener regulation, the banded end must be positive with respect to the opposite end.
