Nexperia USA Inc. PMEG1020EH,115

Overview

PMEG1020EH from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 10 V reverse voltage and 2 A forward current, featuring ultra-low forward voltage (350–460 mV at 2 A) in a compact SOD123F surface-mount package. It serves as a low-loss unidirectional power switch in DC/DC converters and polarity protection circuits.

For engineers reviewing the PMEG1020EH datasheet, PMEG1020EH pinout, PMEG1020EH application, or PMEG1020EH equivalent, key selection criteria include its 350–460 mV VF at 2 A, 1.2–3 mA IR at 10 V, 40–50 pF junction capacitance, thermal resistance of 330 K/W (j-a), and SOD123F footprint compatibility with high-density PCB layouts.

Technical Context

This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its ultra-low VF stems from optimized metal–semiconductor interface design and low series resistance, enabling high conduction efficiency at low voltages.

Thermal performance is defined by two mounting conditions: R_th(j-a) = 330 K/W on standard FR4 (single-sided copper), and R_th(j-sp) = 150 K/W when cathode pad area is increased to 1 cm² - critical for sustained 2 A operation in thermally constrained designs.

FAQ

Is PMEG1020EH suitable for automotive applications?

No. The datasheet explicitly states this device is non-automotive qualified. It lacks AEC-Q101 qualification, has no automotive-grade screening, and is not tested to automotive temperature or reliability standards. Automotive alternatives must be selected from Nexperia's -Q qualified portfolio.

What is the maximum continuous forward current at 85 °C ambient?

At T_amb = 85 °C, the maximum continuous forward current is derated to approximately 1.3 A, based on thermal resistance (330 K/W) and junction temperature limit (150 °C). This assumes standard FR4 mounting with single-sided copper and no additional heatsinking.

How does the guard ring affect layout requirements?

The integrated guard ring eliminates need for external field plates or spacing extensions around the die. Layout follows standard SOD123F footprint (Figure 5); no extra clearance beyond datasheet-recommended solder land dimensions is required for voltage standoff.

Can PMEG1020EH replace PMEG2010AE in existing designs?

No. PMEG2010AE has 20 V V_R and 1 A I_F, while PMEG1020EH offers 10 V V_R and 2 A I_F. Substitution would reduce reverse voltage margin and increase forward current capability - only acceptable if system V_R stress remains <10 V and thermal design accommodates higher I_F.
