1N5956CP/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5956CP/TR12 is a glass-encapsulated Zener diode with a nominal voltage of 200V and a maximum power dissipation of 1.5W. It features a ±2% tolerance, a maximum dynamic impedance of 1200 Ohms, and a reverse leakage current of 1µA at 152V. The device operates within a temperature range of -65°C to +175°C and utilizes a DO-41 axial lead package.

Single Zener Diodes Feature Summary

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

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' corresponds to the required 2% tolerance level as defined in the official part nomenclature. Confirm that the 'TR12' suffix indicates tape and reel packaging compliant with EIA-296 standards. Ensure the component meets the necessary environmental screening requirements for the intended deployment environment.

Single Zener Diodes Selection Notes

Select this component when a precise 200V regulation point is required with tight tolerance constraints. The glass encapsulation provides superior thermal resistance and hermetic sealing compared to plastic alternatives. Consider the axial lead format for through-hole mounting configurations where standard JEDEC dimensions are preferred.

Single Zener Diodes Part Context

This component belongs to the 1N5913BG–1N5956BG series of 1.5-watt Zener diodes manufactured by Microsemi Corporation. The series covers a voltage selection from 3.3V to 200V with various tolerance options. The 1N5956 variant specifically addresses the upper end of this voltage range within the axial-leaded glass package family.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5956BG (glass) or 1N5956BP (plastic). Verify that substitute components match the 200V nominal voltage, 1.5W power rating, and DO-41 package dimensions.
