Nexperia USA Inc. PMEG3010EH-QX

Overview

PMEG3010EH-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 1 A forward current and 30 V reverse voltage, featuring a typical forward voltage of 450 mV at 1 A and qualified to AEC-Q101 for automotive use in low-voltage DC-DC conversion and reverse polarity protection circuits.

For engineers reviewing the PMEG3010EH-QX datasheet, PMEG3010EH-QX pinout, PMEG3010EH-QX application, or PMEG3010EH-QX equivalent, key selection criteria include its ultra-low VF performance, SOD123F package thermal resistance (Rth(j-sp) = 150 K/W), AEC-Q101 qualification, and 9 A non-repetitive peak forward current capability under 8 ms surge conditions.

Technical Context

This Schottky diode employs a planar die structure with an integrated guard ring to enhance ruggedness against electrical overstress and transient voltage spikes. Its low barrier height enables sub-500 mV forward voltage at rated current while maintaining low reverse leakage (≤150 µA at 30 V).

The device operates within a junction temperature range of −65 °C to 150 °C and delivers stable performance across ambient temperatures from −40 °C to +150 °C, supported by validated thermal metrics including Rth(j-a) = 330 K/W (free air) and Rth(j-sp) = 150 K/W on FR4 PCB with cathode pad.

FAQ

Is PMEG3010EH-QX pin-compatible with PMEG3010AEH?

No. PMEG3010EH-QX uses the SOD123F package with 2.6 mm × 1.6 mm body dimensions and specific solder land layout per Figure 6, whereas PMEG3010AEH is in SOD123 (2.7 mm × 1.7 mm) with different thermal pad geometry and footprint tolerances.

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

For Rth(j-sp) = 150 K/W, the datasheet specifies a 1 cm² tin-plated copper pad connected to the cathode terminal. Increasing pad size beyond 1 cm² yields diminishing returns; no derating is required below 55 °C solder point temperature.

Does PMEG3010EH-QX support reflow soldering per JEDEC J-STD-020?

Yes. The SOD123F package is qualified for lead-free reflow per JEDEC J-STD-020D, with peak temperature ≤260 °C and time above 217 °C limited to 60–150 seconds, matching the footprint dimensions shown in Figure 6.

How does guard ring integration affect reverse recovery behavior?

As a Schottky diode, PMEG3010EH-QX has no minority-carrier storage and therefore exhibits zero reverse recovery time (trr). The guard ring improves voltage standoff uniformity and reduces edge leakage but does not alter the intrinsic majority-carrier conduction mechanism.
