1PMT5923BE3/TR7

Single Zener Diodes Overview

The Microsemi Corporation 1PMT5923BE3/TR7 is a surface mount Zener diode housed in the Powermite DO-216AA package. It provides a nominal Zener voltage of 8.2 V with a standard tolerance of ±5%. The device supports a maximum DC power dissipation of 3.0 W when utilizing the integral heat sink tab. Electrical characteristics include a dynamic impedance of 3.5 Ohms at a test current of 45.7 mA and a reverse leakage current of 5 µA at 6.5 V. The component operates within a junction temperature range of -55 °C to +150 °C.

Single Zener Diodes Feature Summary

• Powermite surface mount packaging with a full metallic bottom to prevent solder flux entrapment
• Integral locking tab acts as an efficient heat path for external heat sinking
• Compatible with automatic insertion equipment for streamlined assembly

Single Zener Diodes Applications

• Voltage regulation in high-density circuit boards
• Overvoltage protection circuits requiring low parasitic effects
• Reference voltage generation in precision analog applications

Single Zener Diodes Procurement Notes

Verify that the specific ordering suffix matches the required tolerance and compliance standards, as variations exist within the series. Confirm RoHS status and lead times directly with authorized distributors or the manufacturer, as availability may vary by region. Ensure the procurement documentation explicitly references the DO-216AA package and the correct electrical parameters for the 8.2 V variant.

Single Zener Diodes Selection Notes

Select this component when a 3.0 W power handling capability is required in a compact surface mount form factor. The design is suitable for applications demanding low reverse leakage and tight voltage tolerances. Consider the thermal resistance from junction to tab when designing heat dissipation paths. Verify compatibility with automated pick-and-place machinery due to the unique package geometry.

Single Zener Diodes Part Context

This part belongs to the Microsemi Powermite 1PMT5913B through 1PMT5956B series of low noise Zener diodes. The series utilizes the DO-216AA package to deliver higher power handling than traditional small signal packages while maintaining a small footprint. The family offers a wide range of Zener voltages from 3.3 V to 200 V.

Single Zener Diodes Replacement Considerations

Direct replacements must match the 8.2 V Zener voltage, 3.0 W power rating, and DO-216AA package dimensions. Verify equivalent dynamic impedance and thermal resistance specifications to ensure performance parity in existing designs.
