1PMT5941AE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT5941AE3/TR13 is a surface-mount Zener diode rated for 3.0 watts of DC power dissipation with the tab connected to a heat sink. It features a nominal Zener voltage of 47 Volts, tested at a current of 8.0 mA. The device exhibits a maximum dynamic impedance of 67 Ohms and a reverse leakage current not exceeding 1 microampere at 35.8 Volts. It operates within a junction temperature range of -55°C to +150°C and utilizes the DO-216AA Powermite package.

Single Zener Diodes Feature Summary

• Powermite surface mount packaging provides high power handling in a compact form factor
• Integral metallic locking tabs function as heat sinks to improve thermal performance
• Full metallic bottom design prevents solder flux entrapment during assembly
• ESD rating exceeds 16kV according to the human body model

Single Zener Diodes Applications

• Voltage regulation circuits requiring surface mount technology
• Transient voltage suppression applications
• Automatic insertion equipment manufacturing processes

Single Zener Diodes Procurement Notes

Verify the specific suffix 'E3' against official documentation to confirm compliance details, as datasheet references primarily list the 'B' suffix series. Confirm that the TR13 tape and reel configuration matches the required EIA Standard 481 specifications for your automated assembly lines before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 47 Volt Zener reference is needed with significant power dissipation capabilities in a small footprint. Ensure the application can utilize the tab connection for thermal management to achieve the full 3.0 Watt rating. Verify that the 67 Ohm dynamic impedance meets the noise and stability requirements of the target circuit design.

Single Zener Diodes Part Context

This part belongs to the 1PMT59xx series of Powermite Zener diodes manufactured by Microchip Technology. The series covers a wide voltage range from 3.3 Volts to 200 Volts. These devices are designed to replace larger through-hole packages while maintaining equivalent power handling capabilities in modern surface mount assemblies.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1PMT5941 variants such as the 1PMT5941B or 1PMT5941BT1G, provided the electrical characteristics and package dimensions remain compatible with the existing board layout and thermal requirements.
