Nexperia USA Inc. PMEG10020ELXEX

Overview

PMEG10020ELXEX from Nexperia is a planar Schottky barrier rectifier in CFP3-HP (SOD123HP) package, designed for high-efficiency DC-to-DC conversion and freewheeling applications. It delivers 2 A average forward current at 100 V reverse voltage, with typ. 780 mV forward voltage at 2 A and ultra-low 30 nA reverse leakage at 25 °C - enabling low-loss operation in compact power supplies.

For engineers reviewing the PMEG10020ELXEX datasheet, PMEG10020ELXEX pinout, PMEG10020ELXEX application, or PMEG10020ELXEX equivalent, key selection criteria include its low VF/IR trade-off, clip-bond thermal performance, SOD123HP footprint compatibility, and robust 50 A non-repetitive surge rating for transient resilience.

Technical Context

This Schottky rectifier uses a planar metal–semiconductor junction to achieve fast switching with near-zero reverse recovery charge (Qrr = 13 nC) and sub-4 ns step recovery time - eliminating minority-carrier tail effects typical of PN diodes. Its clip-bond construction directly connects the cathode to an exposed heatsink pad, reducing Rth(j-sp) to 6 K/W.

Thermal derating is defined across three mounting conditions: standard FR4 (Rth(j-a) = 200 K/W), enhanced cathode pad (115 K/W), and solder-point referenced (6 K/W). Junction temperature is rated to 175 °C, supporting operation in thermally constrained industrial and telecom power stages.

Key Specifications

Pinout & Package

Encapsulated in CFP3-HP (SOD123HP) surface-mount plastic package: 2.80 mm × 1.80 mm × 0.90 mm body, with exposed cathode thermal pad on underside. Standard footprint per Fig. 19 (solder land: 2.05 mm × 1.05 mm).

FAQ

What is the maximum junction temperature and how does it affect derating?

The absolute maximum junction temperature is 175 °C. Derating curves in Figures 8–10 show that average forward current drops from 2 A at 25 °C ambient to ~1.2 A at 100 °C ambient on standard FR4, and to ~1.6 A at 100 °C with a 1 cm² cathode pad. Thermal design must respect Rth(j-sp) = 6 K/W to avoid exceeding Tj limit under sustained 2 A load.

Is PMEG10020ELXEX suitable for automotive applications?

No - this device is not AEC-Q200 qualified or automotive grade. Nexperia explicitly states in Section 15 that non-automotive qualified products like PMEG10020ELXEX are unsuitable for safety-critical or life-support systems. It lacks automotive-specific testing for temperature cycling, humidity, and vibration, and carries no automotive warranty.

How does the SOD123HP package differ from standard SOD-123?

SOD123HP (CFP3-HP) features an enlarged, exposed cathode thermal pad on the bottom surface - unlike standard SOD-123 which has fully insulated leads. This enables direct thermal conduction to PCB copper, reducing Rth(j-sp) to 6 K/W versus >30 K/W in standard SOD-123. Footprint dimensions also differ: SOD123HP uses 2.05 mm × 1.05 mm solder land vs. 1.6 mm × 1.6 mm for SOD-123.

Can PMEG10020ELXEX replace a PN junction rectifier in an existing design?

Yes - with caveats. Its 100 V VR and 2 A IF(AV) match many 1N540x or MUR series parts, but its Schottky nature means zero reverse recovery time and lower VF. However, IR rises sharply with temperature (500 µA @ 125 °C), so ensure reverse-bias power dissipation remains within thermal limits. Also verify layout accommodates the SOD123HP footprint and cathode pad.
