1PMT4124CE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT4124CE3/TR13 is a surface mount low noise 1 watt Zener diode in the Powermite package series. It provides a nominal Zener voltage of 43 V at a test current (IZT) of 250 µA, with a maximum Zener impedance (ZZT) of 250 Ohms and a maximum reverse leakage current (IR) of 0.01 µA. The device features a maximum steady-state power dissipation of 1.0 W, a junction-to-case thermal resistance of 30 °C/W, and operates within a temperature range of -55 °C to +150 °C. It includes a full metallic bottom for heat sinking and is RoHS compliant.

Single Zener Diodes Feature Summary

• Features a unique locking tab design that serves as an integral heat sink with very low thermal resistance junction to case.
• Includes a full-metallic bottom that eliminates the possibility of solder flux entrapment during assembly.
• Provides low noise density performance measured over a 1–3 kHz frequency bandpass filter at IZT.
• Compatible with automatic insertion equipment and designed for high-density and low-profile mounting.

Single Zener Diodes Applications

• Voltage regulation circuits requiring low noise performance
• High-density surface mount electronic assemblies
• Automatic insertion equipment manufacturing processes

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix TR13 corresponds to the tape and reel packaging format required for your automated assembly line. Confirm that the e3 designation indicates lead-free compliance matching your environmental standards. Ensure the C suffix tolerance level aligns with your circuit requirements before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 1-watt power handling capability is needed in a compact surface mount footprint. Consider the 43 V nominal voltage and 250 Ohm impedance specifications for precise reference applications. Evaluate the low thermal resistance junction-to-case rating if operating near maximum power dissipation limits.

Single Zener Diodes Part Context

This part belongs to the Microchip Powermite series, which offers surface mount equivalents to JEDEC registered axial-leaded 1N4099 through 1N4135 and 1N4625 through 1N4627 series diodes. The series provides higher power handling capabilities compared to standard small signal packages while maintaining low noise characteristics suitable for sensitive analog circuits.

Single Zener Diodes Replacement Considerations

Direct replacements include other parts within the 1PMT4099–1PMT4135Ce3 series from Microchip Technology. Verify equivalent Zener voltage and impedance values when substituting with components from different manufacturers.
