1PMT4109E3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT4109E3/TR13 is a surface mount low noise 1 watt Zener diode in the Powermite series. It provides a nominal Zener voltage of 15V at a test current of 250µA, with a maximum impedance of 100 Ohms and reverse leakage current of 0.05µA. The device features a metallic bottom for heat dissipation and operates within a junction temperature range of -55°C to +150°C.

Single Zener Diodes Feature Summary

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

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 suffix against official documentation to confirm package type and compliance status. Confirm RoHS compliant versions are available if required by environmental standards. Ensure procurement channels source directly from authorized distributors to guarantee authenticity and traceability of the component.

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 DO-216 package dimensions for PCB layout constraints. Evaluate the low thermal resistance junction-to-case rating for effective heat management in enclosed environments.

Single Zener Diodes Part Context

This part belongs to the Microchip Powermite surface mount low noise 1 watt Zener package series. It serves as a surface mount equivalent to JEDEC registered 1N4099 through 1N4135 series devices but offers additional power handling capabilities and size advantages compared to traditional axial-leaded counterparts.

Single Zener Diodes Replacement Considerations

Surface mount equivalents include the 1N4099UR through 1N4135UR series in the DO-213AA package. Axial-leaded replacements include the standard 1N4099 through 1N4135 series in the DO-35 package.
