1PMT4124E3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT4124E3/TR13 is a surface mount low noise 1 watt Zener diode in the Powermite package. It provides a nominal Zener voltage of 43 V at a test current of 250 µA, with a maximum impedance of 250 Ohms and reverse leakage current of 0.01 µA. The device features a full metallic bottom for heat dissipation and solder flux elimination. It operates within a junction temperature range of -55 to +150 °C, supports steady-state power dissipation up to 1.0 W, and includes automatic insertion equipment compatibility.

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 specification measured over a 1–3 kHz frequency bandpass filter

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix against official documentation to confirm tape and reel packaging quantities and RoHS compliance status. Confirm that the e3 designation aligns with lead-free plating requirements. Ensure the part number matches the exact voltage tolerance level required for the circuit design before finalizing procurement orders.

Single Zener Diodes Selection Notes

Select this component when a 1-watt surface mount Zener diode with low noise characteristics is required. The Powermite package offers superior thermal performance compared to standard axial equivalents. Consider the 43 V nominal voltage and 250 µA test current specifications to ensure proper biasing conditions are met within the target application circuit constraints.

Single Zener Diodes Part Context

This device belongs to the Microchip Powermite series of low noise 1 watt Zener diodes. It is designed as a surface mount replacement for the JEDEC registered 1N4099 through 1N4135 and 1N4625 through 1N4627 series components. The series provides extensive selection from 5.1 to 100V Zener voltages while maintaining high power handling capabilities in a compact form factor.

Single Zener Diodes Replacement Considerations

Direct surface mount replacements include other variants within the 1PMT4099–1PMT4135e3 series. For axial-leaded equivalents, consider the 1N4099–1N4135 series. Surface mount axial equivalents are available in the DO-213AA package as 1N4099UR–1N4135UR.
