Nexperia USA Inc. PMEG10010ELXEX

Overview

PMEG10010ELXEX from Nexperia is a planar Schottky barrier rectifier in CFP3-HP (SOD123HP) package, designed for high-efficiency DC-to-DC conversion and freewheeling roles in power supplies. It delivers 1 A average forward current at 170 °C solder point temperature, 100 V reverse voltage rating, and ultra-low 30–150 nA reverse leakage at 25 °C - enabling low-loss operation in SMPS and OR-ing circuits.

For engineers reviewing the PMEG10010ELXEX datasheet, PMEG10010ELXEX pinout, PMEG10010ELXEX application, or PMEG10010ELXEX equivalent, key selection criteria include its 720–780 mV forward voltage at 1 A/25 °C, 6 K/W junction-to-solder-point thermal resistance, 50 A non-repetitive surge capability, and exposed-cathode thermal pad for enhanced PCB heat dissipation.

Technical Context

This Schottky rectifier uses a planar metal-semiconductor junction architecture optimized for low VF and minimal IR across wide temperature ranges. Its clip-bond construction directly connects the cathode to an exposed copper tab, reducing thermal resistance to just 6 K/W from junction to solder point.

The device exhibits negligible reverse recovery (trr ≤ 4 ns step recovery), no minority-carrier storage, and stable capacitance (25–55 pF) under 1–10 V reverse bias - making it suitable for high-frequency switching topologies where diode switching loss and EMI must be minimized.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable solder point temperature for continuous operation?

The datasheet specifies Tsp ≤ 170 °C for 1 A average forward current at 50% duty cycle. Exceeding this temperature risks accelerated degradation of the clip bond interface and long-term reliability loss. For sustained 1 A operation, maintain the cathode pad temperature below 170 °C using ≥1 cm² copper area and thermal vias if ambient exceeds 85 °C.

Can PMEG10010ELXEX replace a standard SOD123 Schottky in existing layouts?

No - although footprint-compatible, the SOD123HP variant has an extended cathode pad (2.45 mm × 1.05 mm vs. 2.05 mm × 0.75 mm) and requires the larger reflow land pattern shown in Figure 19. Using the standard SOD123 footprint will compromise thermal performance and mechanical reliability due to insufficient solder joint area on the exposed tab.

How does its reverse recovery behavior differ from fast recovery diodes?

As a Schottky device, PMEG10010ELXEX has no minority-carrier storage - resulting in trr ≤ 4 ns (step recovery) and zero reverse recovery charge (Qrr ≈ 0 nC). This eliminates switching tail current and associated losses, unlike PN-junction fast recovery diodes which exhibit Qrr > 10 nC and trr > 25 ns, causing higher EMI and thermal stress at >100 kHz.

Is this part qualified for automotive applications?

No - the datasheet explicitly states this is a non-automotive qualified product. It is not tested to AEC-Q101, lacks automotive-grade process controls, and has no guaranteed operation over -40 °C to +150 °C junction range. For automotive use, select Nexperia's AEC-Q101 qualified equivalents such as PMEG1010AEB,000.
