1PMT4109CE3/TR7

Single Zener Diodes Overview

The Microchip Technology 1PMT4109CE3/TR7 is a surface mount low noise 1 watt Zener diode in the Powermite package. It provides a nominal Zener voltage of 15 V at a test current of 250 µA, with a maximum impedance of 100 Ohms and reverse leakage current of 0.05 µA. The device features a ±2% tolerance due to the 'C' suffix and RoHS compliance indicated by 'e3'. It operates within a junction temperature range of -55 °C to +150 °C, dissipating up to 1.0 W steady-state power.

Single Zener Diodes Feature Summary

• Features a full-metallic bottom design that eliminates solder flux entrapment during assembly.
• Incorporates a unique locking tab serving as an integral heat sink for low thermal resistance.
• Provides low noise density performance measured in a 1–3 kHz frequency bandpass filter.
• Compatible with automatic insertion equipment for high-density mounting.

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes against official documentation to confirm RoHS compliance status and tolerance levels. Ensure procurement channels provide valid datasheets matching DS00005773A. Confirm package type and marking details align with project requirements before finalizing orders.

Single Zener Diodes Selection Notes

Select this component when a 15 V reference with tight ±2% tolerance is required. The Powermite package offers superior thermal management compared to standard equivalents. Consider the low noise characteristics for sensitive analog applications requiring stable voltage references under varying load conditions.

Single Zener Diodes Part Context

This part belongs to the Powermite series of low noise 1 watt Zener diodes. It serves as a surface mount equivalent to JEDEC registered axial-leaded series such as 1N4099 through 1N4135. The device maintains similar electrical characteristics while providing enhanced power handling and size advantages for modern PCB layouts.

Single Zener Diodes Replacement Considerations

Direct replacements include other parts within the 1PMT4099–1PMT4135Ce3 series or JEDEC equivalents like 1N4109. Verify that substitute components match the 15 V nominal voltage, ±2% tolerance requirement, and DO-216 package dimensions.
