1PMT4110CE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1PMT4110CE3/TR13 is a surface mount low noise 1 watt Zener diode in the Powermite package. It provides a nominal Zener voltage of 16 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 full-metallic bottom for heat dissipation and soldering reliability. Operating temperature range spans from -55 °C to +150 °C, with steady-state power dissipation rated at 1.0 W.

Single Zener Diodes Feature Summary

• Features a unique locking tab design that serves as an integral heat sink with very low thermal resistance junction-to-case.
• Includes a full-metallic bottom construction that eliminates the possibility of solder flux entrapment during assembly.
• Provides low noise density performance within a specified frequency bandpass filter at the test current.
• Compatible with automatic insertion equipment and designed for high-density and low-profile mounting.

Single Zener Diodes Applications

• Voltage regulation over broad operating current and temperature ranges
• High-density circuit board mounting applications
• Low-noise reference circuits requiring stable breakdown voltage

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required tolerance level and packaging format. Confirm RoHS compliance status by checking for the e3 designation in the part number. Ensure the reel quantity aligns with production requirements. Cross-reference the datasheet revision date to confirm the latest electrical characteristics are applied. Validate the moisture sensitivity classification against storage and handling protocols.

Single Zener Diodes Selection Notes

Select this component when a 1-watt power rating and low noise profile are required for surface mount designs. Consider the DO-216 package dimensions for footprint compatibility. Evaluate the thermal resistance specifications if operating near maximum power dissipation limits. Compare the impedance and leakage parameters against stricter circuit requirements. Verify the temperature coefficient meets the stability needs of the application.

Single Zener Diodes Part Context

This device belongs to the Powermite series of low noise 1 watt Zener diodes manufactured by Microchip Technology. The series offers an extensive selection of voltages ranging from 5.1 V to 100 V. It serves as a surface mount equivalent to JEDEC registered axial-leaded series, providing higher power handling capability in a compact form factor.

Single Zener Diodes Replacement Considerations

Direct replacements include other 1PMT4110 variants with different suffixes for tolerance or packaging. Surface mount equivalents from the 1N4099 through 1N4135 series may be considered if leaded packages are acceptable. Verify pinout and thermal characteristics match before substituting.
