1PMT5954C/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT5954C/TR13 is a surface-mount Zener diode housed in the Powermite DO-216AA package. It provides a nominal Zener voltage of 160 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 (IZT) of 2.3 mA, a dynamic impedance (ZZT) of 700 Ohms, and a reverse leakage current of 6500 µA at 121.6 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.
• Designed for compatibility with automatic insertion equipment due to its innovative Powermite packaging.
• Provides high electrostatic discharge (ESD) protection exceeding 16 kV per the human body model.

Single Zener Diodes Applications

• Voltage regulation in surface-mount circuit designs
• Protection circuits requiring high ESD immunity
• Automated assembly manufacturing processes

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tolerance levels and compliance status. Confirm the package type matches the required footprint and thermal management needs. Ensure the component meets all relevant environmental regulations applicable to your region before finalizing procurement decisions.

Single Zener Diodes Selection Notes

Select this component when a precise 160 V reference is required with tighter than standard tolerances. The 3 W power rating and low thermal resistance make it suitable for applications needing robust heat dissipation in a compact form factor. Consider the ±2% tolerance if standard variations are insufficient for circuit stability.

Single Zener Diodes Part Context

This part belongs to the 1PMT59xx series of 3 Watt Zener diodes manufactured by Microchip Technology. The series utilizes the Powermite surface mount package, which offers size advantages over traditional through-hole components while maintaining high power handling capabilities. The 'C' designation specifically denotes the tighter voltage tolerance variant within this product family.

Single Zener Diodes Replacement Considerations

Consult official datasheets for direct substitutes within the same series or equivalent packages from other manufacturers. Verify that any replacement maintains the 160 V Zener voltage, 3 W power rating, and compatible DO-216AA footprint.
