1PMT5922C/TR13

Single Zener Diodes Overview

The Microsemi Corporation 1PMT5922C/TR13 is a surface mount Zener diode housed in the Powermite DO-216AA package. It provides a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%. The device operates at a test current of 50 mA and features a maximum dynamic impedance of 3.0 Ohms. It supports a DC power dissipation of 3.0 watts when mounted to TAB 1, with a thermal resistance of 30°C/W from junction to TAB 1. The component withstands reverse voltages up to 6.0 V and exhibits low reverse leakage current.

Single Zener Diodes Feature Summary

• Powermite surface mount packaging with full metallic bottom to eliminate solder flux entrapment
• Integral heat sink locking tabs for efficient thermal management
• High ESD rating exceeding 16kV per human body model
• Compatible with automatic insertion equipment

Single Zener Diodes Applications

• Voltage regulation circuits requiring high power handling in compact form factors
• Protection against electrostatic discharge (ESD) events
• Applications utilizing automatic insertion manufacturing equipment

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the required ±2% tolerance variant during procurement. Confirm that the TR13 designation corresponds to the 13-inch tape and reel containing 12,000 pieces as specified in the datasheet. Ensure compatibility with the DO-216AA footprint on the target printed circuit board layout.

Single Zener Diodes Selection Notes

Select this component when a 7.5 V reference is needed with tighter than standard tolerances. The 3.0 W power capability allows it to replace larger axial-leaded packages in space-constrained designs. Verify that the operating environment accommodates the -55°C to +150°C junction temperature range and that the mounting plane can effectively utilize the integral heat sink tab.

Single Zener Diodes Part Context

This part belongs to the 1PMT5913B through 1PMT5956B series of 3.0 Watt Zener Diodes manufactured by Microsemi. The series utilizes the Powermite surface mount package to deliver high power handling capabilities typically found in larger components. The 'C' suffix denotes a specific voltage tolerance grade within this broader product family.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1PMT5922 variants such as 1PMT5922B or 1PMT5922E3, provided the tolerance requirements align with the application needs.
