Nexperia USA Inc. PMEG100T10ELRX

Overview

PMEG100T10ELRX from Nexperia is a trench Schottky barrier rectifier optimized for high-efficiency DC-to-DC conversion and reverse polarity protection, featuring 100 V reverse voltage rating, 1 A average forward current, 670–750 mV forward voltage at 1 A/25 °C, <0.9 µA reverse leakage at 100 V/25 °C, and CFP3 (SOD123W) surface-mount package.

For engineers reviewing the PMEG100T10ELRX datasheet, PMEG100T10ELRX pinout, PMEG100T10ELRX application, or PMEG100T10ELRX equivalent, key selection criteria include low-leakage performance at elevated temperature, thermal resistance to solder point (130 K/W), clip-bonded power capability, and compatibility with compact LED driver and OR-ing circuits requiring minimal footprint and fast recovery.

Technical Context

This device employs trench Schottky architecture to minimize forward voltage while suppressing reverse leakage-critical for maintaining efficiency in high-frequency switching topologies. Its clip-bonding construction enhances thermal transfer from junction to solder point, enabling sustained 1 A operation at ambient temperatures up to 100 °C on standard FR4 PCBs.

The diode exhibits step-recovery behavior with trr = 4 ns and Qrr = 8 nC under defined ramp conditions, supporting clean freewheeling in synchronous rectifiers. Its low Cd (36 pF at 10 V) and stable VF across -40 °C to 150 °C ensure predictable timing and conduction loss in wide-temperature industrial power supplies.

FAQ

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature is 175 °C, and the device is rated for continuous 1 A average forward current at Tsp ≤ 166 °C. Derating curves (Fig. 8–9) confirm full 1 A operation up to 100 °C ambient on standard FR4 with 1 cm² cathode pad, making it suitable for enclosed industrial power supplies without forced cooling.

How does the CFP3 package improve thermal performance over standard SOD123?

The CFP3 (SOD123W) package uses clip-bonding instead of wire bonding, directly attaching the die to the cathode leadframe. This reduces Rth(j-sp) to 130 K/W - 23% lower than typical SOD123 devices - and enables 1.15 W power dissipation with only 150 °C junction rise, critical for high-density board layouts.

Is PMEG100T10ELRX suitable for reverse polarity protection in 24 V automotive accessory circuits?

Yes - its 100 V VR rating provides 4× margin over 24 V nominal systems, and its 0.18–1 mA IR at 125 °C ensures reliable blocking during hot-cranking (−40 °C to +125 °C ambient). However, it is not AEC-Q200 qualified; for automotive-grade use, consult Nexperia's automotive-qualified equivalents.

What is the significance of the "LA" marking on the device body?

The "LA" laser marking identifies the PMEG100T10ELRX variant per Nexperia's ordering matrix. The bar adjacent to pin 1 denotes the cathode terminal - a critical orientation cue during automated placement and visual inspection to prevent reverse installation in polarity-sensitive circuits like OR-ing and reverse protection.
