Nexperia USA Inc. PMEG100T10ELR-QX

Overview

PMEG100T10ELR-QX from Nexperia is a 100 V, 1 A trench Schottky barrier rectifier in CFP3 (SOD123W) package, designed for high-efficiency freewheeling and reverse polarity protection in automotive DC-DC converters. It delivers 670 mV typical forward voltage at 1 A and 25 °C, 0.1 µA typical reverse leakage at 100 V/25 °C, and is qualified to AEC-Q101 for under-hood LED lighting and OR-ing applications.

For engineers reviewing the PMEG100T10ELR-QX datasheet, PMEG100T10ELR-QX pinout, PMEG100T10ELR-QX application, or PMEG100T10ELR-QX equivalent, key selection criteria include low IRM (1.2 A), ultra-low Qrr (8 nC), thermal resistance to solder point (130 K/W), and junction temperature rating up to 175 °C - all critical for thermally constrained automotive power rails.

Technical Context

This device uses trench Schottky architecture to minimize forward voltage while maintaining low reverse leakage across temperature. Its clip-bonded construction enables 1.4 A continuous forward current and 40 A non-repetitive surge capability, supporting high-duty-cycle switching in SMPS and OR-ing circuits.

The diode exhibits step-recovery trr of 4 ns and ramp-recovery trr of 11.5 ns, with VFRM of 560 mV during fast dIF/dt transitions. Its capacitance drops from 125 pF at 1 V to 36 pF at 10 V reverse bias, enabling stable high-frequency operation in buck converter freewheel paths.

FAQ

What is the maximum allowable solder point temperature for PMEG100T10ELR-QX during reflow?

The device is rated for a maximum solder point temperature of 166 °C under 0.5 duty cycle square-wave conditions. Reflow profiles must limit peak temperature to ≤260 °C for ≤10 seconds per J-STD-020, with thermal profile validated using the recommended SOD123W footprint (1.2 mm × 1.4 mm cathode land, 0.1 mm stencil).

Does PMEG100T10ELR-QX support bidirectional current flow in OR-ing configurations?

No - it is a unidirectional Schottky rectifier. In OR-ing, it conducts only from anode to cathode, blocking reverse current. For true bidirectional power path control, external MOSFETs with gate drivers are required; this diode serves as passive, low-loss forward conduction element only.

How does the 130 K/W Rth(j-sp) value translate to real-world PCB thermal design?

When mounted on FR4 with a 1 cm² cathode copper pad, the device dissipates 1.15 W at 25 °C ambient before reaching its 175 °C junction limit. This enables 1 A continuous operation without forced air or heatsink in space-constrained automotive modules, provided the pad is solid, unslotted, and tin-plated per Nexperia's layout guidelines.

Is the 0.1 µA reverse leakage specified at DC or pulsed conditions?

The 0.1 µA typical IR value is measured under pulsed conditions (very short pulse to stabilize junction temperature) at VR = 100 V and Tj = 25 °C. At DC bias and elevated temperature (e.g., 125 °C), leakage rises to 0.18–1 mA - a critical design factor for standby power budgeting in always-on vehicle systems.
