Nexperia USA Inc. PMEG100T50ELPX

Overview

PMEG100T50ELPX from Nexperia is a 100 V, 5 A trench Schottky barrier rectifier in CFP5 (SOD128) package, designed for high-efficiency freewheeling and reverse polarity protection in DC-DC converters and LED drivers. It delivers low forward voltage (815–895 mV at 5 A, 25 °C), ultra-low leakage current (0.25–1.75 µA at 100 V, 25 °C), and high thermal robustness with junction temperature up to 175 °C.

For engineers reviewing the PMEG100T50ELPX datasheet, PMEG100T50ELPX pinout, PMEG100T50ELPX application, or PMEG100T50ELPX equivalent, key selection criteria include reverse leakage at 125 °C, thermal resistance to solder point (12 K/W), clip-bonded power capability, and SOD128 footprint compatibility with high-density PCB layouts.

Technical Context

This device uses trench Schottky architecture to minimize forward voltage drop while maintaining low Qrr (10 nC) and low IRM (1.3 A), enabling fast switching with minimal recovery loss in SMPS freewheel paths. Its clip-bonding construction enhances current handling and thermal transfer versus wire-bonded alternatives.

The CFP5 package integrates a large cathode tab for low Rth(j-sp) = 12 K/W and supports 7.1 A continuous forward current at Tsp ≤ 140 °C. Reverse breakdown is rated at 100 V with tight distribution (min 100 V at IR = 1 mA), and diode capacitance is 85 pF at VR = 10 V, 1 MHz.

FAQ

What is the maximum allowable solder point temperature for PMEG100T50ELPX during reflow?

The device supports peak reflow temperatures up to 260 °C for 30 seconds per JEDEC J-STD-020, with maximum solder point (Tsp) of 140 °C under continuous 5 A operation. Thermal design must ensure Tsp remains ≤140 °C using the 1 cm² cathode pad footprint specified in Figure 19.

Does PMEG100T50ELPX support bidirectional current flow?

No. As a Schottky barrier rectifier, it conducts only from anode to cathode. Reverse conduction is blocked up to 100 V, with leakage current limited to 2.2 mA at 125 °C and 100 V. It is not rated for reverse conduction or AC operation.

How does the 12 K/W Rth(j-sp) value impact PCB layout?

This low thermal resistance requires direct copper connection to the cathode tab using a minimum 1 cm² solder pad with thermal vias to inner ground planes. The footprint must match Nexperia's SOD128 reflow land pattern (Figure 19), with no solder mask over the cathode area to ensure full thermal contact.

Can PMEG100T50ELPX replace a standard PN-junction rectifier in existing designs?

Yes, provided VR ≥ 100 V and IF(AV) ≥ 5 A requirements are met. Its lower VF reduces heat generation, but designers must verify that reduced reverse recovery time (9 ns vs. >500 ns for PN diodes) does not induce ringing in snubberless layouts-especially in high-dV/dt flyback transformers.
