1N5913CPE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5913CPE3/TR12 is a commercial-grade, RoHS-compliant Zener diode with a nominal voltage of 3.3V and a 2% tolerance. It provides 1.5W power dissipation in a hermetically sealed DO-41 glass package. The device operates within a junction temperature range of -65°C to +175°C and features a maximum dynamic impedance of 10 Ohms at a test current of 113.6mA.

Single Zener Diodes Feature Summary

• Hermetically sealed glass encapsulation for high reliability
• Inherently radiation hard construction
• Non-sensitive to electrostatic discharge (ESD)
• Metallurgically enhanced internal contact design

Single Zener Diodes Applications

• Voltage regulation over broad operating currents and temperatures
• High-reliability aerospace and defense circuits
• Harsh environment electronic systems

Single Zener Diodes Procurement Notes

Verify the specific suffixes against official documentation to confirm RoHS compliance and tolerance levels. Ensure the TR suffix matches tape-and-reel requirements. Confirm that the commercial grade designation aligns with project specifications rather than military screening levels.

Single Zener Diodes Selection Notes

Select this component when a low-voltage, high-tolerance Zener reference is required in an axial leaded package. The glass construction offers superior thermal resistance compared to plastic equivalents. Consider the radiation hardness for space or high-altitude applications where standard silicon devices may fail.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5913B through 1N5956B series. The 'C' indicates a 2% voltage tolerance, while 'G' denotes the glass casing. The 'e3' signifies RoHS compliance, and 'TR' indicates tape-and-reel packaging. It serves as a commercial alternative to the MIL-PRF-19500 screened BG variants.

Single Zener Diodes Replacement Considerations

Equivalent parts include the 1N5913BG for military screening or 1N5913BP for plastic body construction. Verify that replacement candidates maintain the same 3.3V nominal voltage and 2% tolerance to ensure circuit compatibility.
