1PMT4100C/TR7

Single Zener Diodes Overview

The Microchip Technology 1PMT4100C/TR7 is a surface mount low noise 1 watt Zener diode in the Powermite series. It provides a nominal Zener voltage of 7.5V at a test current of 250µA with a tight tolerance of ±2%. The device features a DO-216 package with a full-metallic bottom for efficient heat dissipation and low thermal resistance. It operates within a junction temperature range of -55°C to +150°C and offers low reverse leakage current and noise density.

Single Zener Diodes Feature Summary

• Surface mount equivalent to JEDEC registered 1N4099 through 1N4135 series with additional power capability
• Full-metallic bottom eliminates solder flux entrapment during assembly
• Unique locking tab design serves as an integral heat sink with very low thermal resistance
• Low noise density and low reverse leakage current

Single Zener Diodes Applications

• High-density and low-profile mounting applications
• Automatic insertion equipment compatible designs
• Voltage regulation over broad operating current and temperature ranges

Single Zener Diodes Procurement Notes

Verify the specific suffix 'C' indicates the 2% tolerance variant and 'TR7' denotes tape and reel packaging. Confirm RoHS compliance status by checking for the e3 designation in the official datasheet or ordering information, as standard tin-lead plated products are not compliant. Ensure the component matches the DO-216 package dimensions and polarity markings specified in the manufacturer's documentation.

Single Zener Diodes Selection Notes

Select this component when a precise 7.5V reference with high accuracy is required in a surface mount configuration. The C suffix ensures tighter voltage tolerance compared to standard versions. Consider the Powermite package benefits for thermal management and automated assembly processes. Verify that the 1W power dissipation rating and thermal characteristics suit the intended circuit environment.

Single Zener Diodes Part Context

This part belongs to the Microchip Powermite low noise 1 watt Zener diode series. It is designed as a surface mount alternative to traditional axial-leaded JEDEC registered parts like the 1N4100. The series offers extensive voltage selection from 5.1V to 100V with options for different tolerance levels and packaging configurations including axial and other surface mount packages.

Single Zener Diodes Replacement Considerations

Direct replacements include the non-suffix 1PMT4100 for standard 5% tolerance or the axial-leaded 1N4100. Surface mount equivalents such as the 1N4100UR in DO-213AA package are also available. Verify pinout compatibility and thermal performance when substituting.
