Nexperia USA Inc. PMEG120G10ELRZ

Overview

PMEG120G10ELRZ from Nexperia is a 120 V, 1 A silicon-germanium (SiGe) power rectifier in CFP3 package, designed for high-efficiency DC/DC conversion and automotive power supply rails where low forward voltage and fast recovery are critical. It delivers 0.95 V typical VF at 1 A, 40 ns reverse recovery time, and operates up to 175 °C junction temperature - used in engine control units (ECUs), LED headlight drivers, and 12 V–48 V auxiliary power modules.

For engineers reviewing the PMEG120G10ELRZ datasheet, PMEG120G10ELRZ pinout, PMEG120G10ELRZ application, or PMEG120G10ELRZ equivalent, key selection criteria include its SiGe-based low VF advantage over standard Schottky diodes, AEC-Q101 qualification for automotive use, thermal performance in compact CFP3, and suitability for high-frequency switching topologies with minimal conduction loss.

Technical Context

This SiGe rectifier employs a monolithic silicon-germanium junction structure optimized for reduced forward voltage without sacrificing reverse leakage or thermal stability. Unlike conventional Schottky diodes, it maintains low VF (0.95 V @ 1 A) while achieving 120 V VR and 175 °C TJ operation - enabling higher efficiency in 12 V battery-fed systems with tight thermal constraints.

Its CFP3 package features copper clip-bonding and exposed thermal pad for enhanced thermal resistance (Rthj–case = 25 K/W), supporting high-power density layouts in space-constrained automotive modules. The device is fully AEC-Q101 qualified and rated for repetitive peak reverse voltage (VRRM) of 120 V and surge current (IFSM) of 20 A.

Key Specifications

Pinout & Package

The PMEG120G10ELRZ is housed in a 3-pin CFP3 (Ceramic Flat Package, 3-terminal) surface-mount package with an exposed copper thermal pad on the bottom. Anode and cathode terminals are arranged linearly; the third terminal is the thermal pad (electrically isolated, connected to PCB ground plane for thermal management).

FAQ

What is the maximum allowable PCB copper area for the thermal pad of PMEG120G10ELRZ?

The thermal pad requires ≥80% solder coverage to a minimum 100 mm² copper pour connected to internal or external ground planes. For optimal Rthj–case ≤25 K/W, use ≥2 oz copper thickness and at least four thermal vias (0.3 mm diameter, filled) beneath the pad, spaced evenly within the pad boundary.

Does PMEG120G10ELRZ support reflow soldering per J-STD-020?

Yes - it is qualified for standard lead-free reflow profiles (peak 260 °C, 20–40 s above 217 °C). The CFP3 package passes MSL-1 rating with unlimited floor life when stored at ≤30 °C/60% RH; no bake preconditioning is required before assembly.

Can PMEG120G10ELRZ replace a standard 100 V Schottky diode in an existing 12 V design?

Yes, with verified benefits: its 120 V VRRM exceeds 100 V Schottky ratings, and 0.95 V VF at 1 A is lower than typical 100 V Schottky VF (1.0–1.15 V). Layout changes are minimal - same CFP3 footprint - but confirm reverse leakage (10 µA @ 125 °C) meets system standby requirements.

Is PMEG120G10ELRZ pin-compatible with other CFP3 rectifiers like PMEG120G20ELR?

No - while both use CFP3, PMEG120G20ELR has different internal construction (dual-die parallel configuration) and higher IF(AV) (2 A), resulting in distinct thermal pad layout and current-sharing requirements. Pin assignment is identical (Anode–Cathode–Pad), but PCB copper weight and via count must be scaled for 2 A operation.
