1PMT5929C/TR7

Single Zener Diodes Overview

The Microchip Technology 1PMT5929C/TR7 is a surface-mount Zener diode housed in the Powermite DO-216AA package. It provides a nominal Zener voltage of 15 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device supports a maximum DC power dissipation of 3.0 W and operates within a junction temperature range of -55 °C to +150 °C. Key electrical characteristics include a test current of 25 mA, a dynamic impedance of 9.0 Ω, and a reverse leakage current of 1 µA at 11.4 V.

Single Zener Diodes Feature Summary

• Features an integral metallic bottom and locking tab that acts as a heat sink to eliminate solder flux entrapment during assembly.
• Provides high power handling capabilities within a compact surface mount footprint suitable for automatic insertion equipment.
• Offers low reverse leakage and high electrostatic discharge (ESD) protection exceeding 16 kV per human body model.

Single Zener Diodes Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Clamping applications in signal processing lines

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix to confirm the tolerance grade, as the 'C' designation indicates a ±2% tolerance which differs from standard variants. Confirm the tape and reel packaging format matches automated assembly requirements. Ensure the component meets RoHS compliance standards if required by the target application environment.

Single Zener Diodes Selection Notes

Select this component when a precise 15 V reference is required with tighter than standard tolerance specifications. The Powermite package is preferred for designs needing efficient thermal management through the mounting tab. Consider the forward voltage drop and dynamic impedance characteristics for accuracy in precision clamping or regulation tasks.

Single Zener Diodes Part Context

This device belongs to the Microsemi Powermite series of 3-watt Zener diodes, now manufactured under Microchip Technology. The series utilizes the DO-216AA surface mount package to deliver robust performance in space-constrained designs. The product line covers a wide voltage range from 3.3 V to 200 V with various tolerance options.

Single Zener Diodes Replacement Considerations

Compatible substitutes include the 1PMT5929B for standard ±5% tolerance or the 1PMT5929D for ±1% tolerance. Other manufacturers offering equivalent 3W DO-216AA Zener diodes with 15 V ratings may be considered if pinout and thermal characteristics align.
