Nexperia USA Inc. PMEG3005EGWJ

Overview

PMEG3005EGWJ from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 0.5 A average forward current, featuring low 380 mV typical forward voltage and 40 µA typical reverse leakage - deployed in low-voltage DC-DC converters and reverse polarity protection circuits.

For engineers reviewing the PMEG3005EGWJ datasheet, PMEG3005EGWJ pinout, PMEG3005EGWJ application, or PMEG3005EGWJ equivalent, key selection criteria include VF vs. IF trade-off at 500 mA, thermal resistance to solder point (190 K/W), SOD123 footprint compatibility, and non-automotive qualification status per revision v.2.

Technical Context

This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve surge robustness under transient reverse stress. Its low VF stems from optimized metal-semiconductor interface engineering, enabling high efficiency in low-voltage (<5 V) power rails.

Thermal performance is defined relative to two PCB mounting conditions: standard SOD123 footprint (Rth(j-a) = 310 K/W) and enhanced cathode pad (1 cm², Rth(j-sp) = 29 K/W). Reverse recovery is effectively zero, eliminating switching loss in high-frequency SMPS topologies.

Key Specifications

Pinout & Package

FAQ

Is PMEG3005EGWJ qualified for automotive applications?

No. Per revision v.2 (October 2023), PMEG3005EGWJ is explicitly designated as non-automotive. It lacks AEC-Q101 qualification, automotive temperature cycling validation, and failure analysis reporting required for automotive use. For automotive designs, select Nexperia's -Q suffix variants or verified alternatives like NSSR0530MX.

What is the maximum allowable PCB copper area for optimal thermal performance?

For lowest Rth(j-sp), Nexperia specifies a 1 cm² tin-plated copper pad connected to pin 1 (cathode) on FR4 PCB - achieving 29 K/W thermal resistance. Smaller pads increase thermal resistance nonlinearly; using less than 0.5 cm² raises Rth(j-sp) above 50 K/W, risking junction overheating above 0.3 A continuous.

Can PMEG3005EGWJ replace a standard PN-junction rectifier in a 5 V SMPS?

Yes - with measurable benefit. Its zero reverse recovery eliminates switching spikes and EMI associated with PN diodes, and its 380 mV VF reduces conduction loss by ~60% versus a typical 1N5817 (VF ≈ 450–600 mV). Ensure layout accounts for lower Cd (55 pF vs. ~100 pF) to maintain loop compensation stability.

What does the 'GE' marking on the device indicate?

The 'GE' laser marking on the SOD123 body is the unique identifier for PMEG3005EGWJ per Nexperia's ordering table. It is not a date code or lot identifier - it directly maps to the full type number and confirms compliance with the October 2023 v.2 data sheet, including non-automotive status and updated thermal characterization.
