Nexperia USA Inc. PMEG4010CEAX

Overview

PMEG4010CEAX from Nexperia is a 40 V, 1 A low forward-voltage Schottky barrier rectifier in SOD323 (SC-76) package, featuring typ. VF = 720 mV at 1 A and typ. IR = 1.5 µA at 40 V/25 °C. It integrates a guard ring for stress protection and is AEC-Q101 qualified for automotive use in reverse polarity protection and DC-DC conversion stages.

For engineers reviewing the PMEG4010CEAX datasheet, PMEG4010CEAX pinout, PMEG4010CEAX application, or PMEG4010CEAX equivalent, key selection criteria include low VF for efficiency-critical 12 V/24 V automotive rails, thermal performance on FR4 PCBs, reverse leakage behavior at 125 °C, and SOD323 footprint compatibility with space-constrained power management layouts.

Technical Context

This MEGA Schottky rectifier uses a planar silicon structure with integrated guard ring to suppress edge breakdown and improve reliability under transient voltage stress. Its low junction capacitance (13.5 pF at VR = 4 V, 1 MHz) and ultrafast trr of 1.8 ns support high-frequency switching in synchronous buck converters.

The device operates with junction temperature up to 150 °C and delivers 1 A average forward current under δ = 0.5 square-wave conditions at Tsp ≤ 110 °C. Thermal resistance Rth(j-sp) is 45 K/W when mounted with a 1 cm² cathode pad - critical for thermal design in sealed automotive modules.

Key Specifications

Pinout & Package

Encapsulated in SOD323 (SC-76), a 2.3 mm × 1.35 mm × 0.95 mm surface-mount plastic package with gull-wing leads. Cathode-side marking "4M" aligns with pin 1.

FAQ

What is the maximum allowable solder point temperature for PMEG4010CEAX during reflow?

The device is rated for a maximum solder point temperature (Tsp) of 110 °C under δ = 0.5 square-wave conditions. For reflow, peak temperature must stay within JEDEC J-STD-020 limits for MSLE Level 1 (260 °C max), but sustained Tsp > 110 °C during operation will derate IF(AV) below 1 A per Fig. 10. Thermal design must ensure steady-state Tsp ≤ 110 °C with defined copper area.

Does PMEG4010CEAX support bidirectional current flow?

No - it is a unidirectional Schottky rectifier. Current flows only from anode to cathode; reverse conduction is blocked up to 40 V. The 1.5 µA reverse leakage at 25 °C is not functional conduction but parasitic leakage, and the device lacks symmetrical structure or control logic for bidirectional operation.

Can PMEG4010CEAX replace a standard PN-junction diode in a 24 V automotive circuit?

Yes - its 40 V VR provides 67 % margin above 24 V nominal, and 720 mV VF cuts conduction loss by ~60 % versus a typical 1N4007 (1.1 V). However, its higher IR at elevated temperature requires verification against system leakage budgets, especially in always-on modules where 1 mA IR at 125 °C may impact sleep current.

Is the "4M" marking on the SOD323 package sufficient for automated optical inspection (AOI)?

Yes - the "4M" laser-marked code meets IPC-A-610 Class 2 contrast and legibility requirements. Its 0.3 mm character height and placement adjacent to cathode (pin 1) enable reliable AOI detection using standard 10 µm/pixel resolution systems, provided lighting is optimized for matte black epoxy surfaces.
