1PMT4624CE3/TR7

Single Zener Diodes Overview

The Microsemi Corporation 1PMT4624CE3/TR7 is a surface mount low noise Zener diode in the Powermite series, housed in a DO-216AA package. It provides a nominal Zener voltage of 43V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a junction temperature range of -55°C to +150°C and features a full-metallic bottom for efficient heat dissipation. RoHS compliant versions are available.

Single Zener Diodes Feature Summary

• Features a unique locking tab design that serves as an integral heat sink with very low thermal resistance from junction to case.
• Provides low noise density measured over a 1–3 kHz frequency bandpass filter at the specified test current.
• Includes a full-metallic bottom construction that eliminates the possibility of solder flux entrapment during assembly.

Single Zener Diodes Applications

• High-density and low-profile mounting on printed circuit boards
• Voltage regulation over broad operating current and temperature ranges
• Automatic insertion equipment integration

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm compliance requirements and packaging options. Ensure the selected variant matches the required voltage tolerance and thermal characteristics for the intended application environment.

Single Zener Diodes Selection Notes

Select this component when precise voltage regulation is required alongside high power handling capabilities. The tight ±2% tolerance makes it suitable for applications demanding strict voltage stability. Consider the low thermal resistance for designs requiring effective heat sinking through the mounting plane.

Single Zener Diodes Part Context

This part belongs to the Microchip Powermite surface mount low noise 1 watt Zener package series. It offers higher power handling capability compared to standard equivalents while maintaining a compact size advantage. The series includes extensive selections ranging from 5.1V to 100V Zener voltages.

Single Zener Diodes Replacement Considerations

Surface mount equivalent to JEDEC registered 1N4624 series components, except with additional power capability.
