1PMT4099E3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT4099E3/TR13 is a surface mount low noise 1 watt Zener diode in the Powermite package. It provides a nominal Zener voltage of 6.8 V at a test current of 250 µA, with a maximum impedance of 200 Ohms and reverse leakage current of 10 µA. The device features a full-metallic bottom for heat dissipation and soldering reliability. RoHS compliant versions are available.

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 junction to case
• Low noise density specified in the 1–3 kHz frequency bandpass filter at IZT

Single Zener Diodes Applications

• High-density and low-profile mounting
• Automatic insertion equipment
• Voltage regulation over broad operating current and temperature range

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm compliance status and packaging details. Confirm that the e3 suffix indicates lead-free RoHS compliance. Ensure the TR13 designation matches the required tape and reel quantity specifications before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 1-watt power handling capability is required in a surface mount form factor. Consider the low thermal resistance junction-to-case for applications needing efficient heat dissipation. Verify that the 6.8 V nominal voltage aligns with circuit requirements and check tolerance levels if tighter specifications are needed.

Single Zener Diodes Part Context

This part belongs to the Powermite low noise 1 watt Zener package series from Microchip Technology. It is designed to offer higher power handling compared to standard equivalents while maintaining a compact size. The series includes extensive selections ranging from 5.1 to 100V Zener voltages.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1PMT4099 variants or JEDEC registered 1N4099 equivalents in DO-35 or DO-213AA packages, provided power ratings and voltage tolerances match.
