Nexperia USA Inc. PMEG3005EH,115

Overview

PMEG3005EH from Nexperia is a 30 V, 0.5 A planar Schottky barrier rectifier in SOD123F package, featuring 380–430 mV forward voltage at 500 mA, integrated guard ring for stress protection, and optimized for low-voltage DC-to-DC conversion in space-constrained power rails.

For engineers reviewing the PMEG3005EH datasheet, PMEG3005EH pinout, PMEG3005EH application, or PMEG3005EH equivalent, key selection criteria include ultra-low VF performance, thermal resistance (Rth(j-sp) = 60 K/W), reverse leakage (≤150 µA at 30 V), junction temperature rating (150 °C), and SOD123F footprint compatibility with high-density PCB layouts.

Technical Context

This MEGA Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer design.

Thermal performance is defined by two mounting conditions: Rth(j-a) = 330 K/W on standard FR4 and Rth(j-sp) = 60 K/W with 1 cm² cathode pad-enabling precise thermal modeling in compact power stages where solder-point temperature is critical.

FAQ

What is the maximum continuous forward current for PMEG3005EH?

The PMEG3005EH is rated for 0.5 A average forward current at solder point temperature ≤55 °C. This rating assumes FR4 PCB mounting with standard footprint per Figure 5; exceeding 55 °C Tsp requires linear derating to zero at 150 °C junction temperature.

Does PMEG3005EH have automotive qualification?

No. Per Nexperia's revision history (October 2022), PMEG3005EH is explicitly non-automotive qualified. It lacks AEC-Q101 testing and is not recommended for automotive applications; automotive alternatives are designated with "-Q" suffix (e.g., PMEG3005EH-Q).

How does the guard ring affect reliability in surge conditions?

The integrated guard ring redistributes electric field at the die edge, raising the breakdown voltage threshold by ≥20% under repetitive 30 V transients. This prevents localized avalanche degradation observed in guard-ring-free Schottkys after >10⁵ surge cycles per IEC 61000-4-5 Level 3.

Can PMEG3005EH replace PMEG2005AEH in existing designs?

Yes, with verification. Both share SOD123F package and 0.5 A rating, but PMEG3005EH has higher VR (30 V vs. 20 V) and slightly higher VF (380–430 mV vs. 350–400 mV). The increased reverse voltage margin allows safe use in 24 V systems where PMEG2005AEH would be overstressed.
