1PMT5933AE3/TR7

Single Zener Diodes Overview

The Microchip Technology 1PMT5933AE3/TR7 is a Zener diode housed in the Powermite surface mount package. It provides a nominal Zener voltage of 22 Volts with a test current of 17 mA and a dynamic impedance of 17.5 Ohms. The device supports a maximum Zener current of 112.2 mA, derived from its 3.0 Watt DC power dissipation rating. Operating junction temperatures range from -55 °C to +150 °C, with a thermal resistance of 30°C/W from junction to TAB 1.

Single Zener Diodes Feature Summary

• Surface mount packaging designed for automatic insertion equipment
• Full metallic bottom eliminates solder flux entrapment during assembly
• Integral locking tab acts as an effective heat sink
• ESD rating exceeding 16kV per human body model

Single Zener Diodes Applications

• Voltage regulation circuits requiring surface mount technology
• Power handling applications utilizing the 3.0 Watt capability
• Automated electronic assembly processes

Single Zener Diodes Procurement Notes

Verify the specific suffix 'AE3' against official documentation to confirm RoHS compliance status and exact manufacturing lot details. Ensure the tape and reel packaging matches EIA Standard 481 requirements for your automated placement equipment. Cross-reference the datasheet revision date to validate all electrical parameters before final integration.

Single Zener Diodes Selection Notes

Select this component when a 22 Volt reference is required in a compact surface mount form factor. The Powermite package offers superior thermal management compared to standard molded packages due to the metallic base. Consider the tight tolerance availability if precise voltage regulation is critical for the target application design.

Single Zener Diodes Part Context

This part belongs to the 1PMT59 series of 3.0 Watt Zener diodes manufactured by Microchip Technology (formerly Microsemi). The series spans voltages from 3.3 to 200 Volts, sharing identical mechanical dimensions and mounting characteristics. The TR7 suffix indicates the standard 7-inch tape and reel packaging configuration containing 3,000 pieces.

Single Zener Diodes Replacement Considerations

Direct substitutes include other 1PMT59 series variants with matching 22 Volt ratings, such as the 1PMT5933B. Verify that any replacement maintains the same Powermite package footprint and thermal resistance specifications to ensure compatibility with existing board layouts.
