Nexperia USA Inc. PMEG2010EH,115

Overview

PMEG2010EH from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1 A forward current, featuring a typical forward voltage of 420 mV at 1 A (pulsed), housed in an SOD123F surface-mount package. It serves as a low-loss unidirectional current switch in DC/DC converters and reverse polarity protection circuits for automotive and industrial power rails.

For engineers reviewing the PMEG2010EH datasheet, PMEG2010EH pinout, PMEG2010EH application, or PMEG2010EH equivalent, key selection criteria include its ultra-low VF (≤500 mV @ 1 A), AEC-Q101 qualification, thermal resistance to solder point (150 K/W), and SOD123F footprint compatibility with space-constrained PCB layouts.

Technical Context

This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve robustness under transient overvoltage stress. Its low junction-to-solder-point thermal resistance (150 K/W) enables reliable operation up to 150 °C junction temperature when mounted on FR4 with cathode pad area of 1 cm².

The device delivers low forward voltage across a wide current range: 210–240 mV at 10 mA, 355–390 mV at 500 mA, and 420–500 mV at 1 A - enabling high-efficiency rectification in low-voltage, high-current paths where conduction loss dominates thermal design.

FAQ

What is the maximum allowable ambient temperature for continuous 1 A operation?

At 1 A continuous forward current, the PMEG2010EH requires ambient temperature ≤55 °C per its limiting values table. This assumes mounting on FR4 with standard footprint (R_th(j-a) = 330 K/W); exceeding 55 °C necessitates derating or improved thermal layout such as enlarged cathode pad (R_th(j-sp) = 150 K/W).

Is the SOD123F package compatible with standard reflow profiles for lead-free soldering?

Yes - Nexperia specifies compatibility with JEDEC J-STD-020D reflow profiles. The recommended peak temperature is 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s. Figure 6 in the datasheet provides the exact solder land pattern (2.9 mm × 1.6 mm) and paste deposit dimensions for optimal wetting and void control.

How does the guard ring affect surge withstand capability?

The integrated guard ring redistributes electric field at the silicon edge, raising the effective breakdown voltage margin and enabling stable operation under repetitive 40 V transients (per AEC-Q101 HBM testing). This eliminates need for external TVS clamping in many 12 V automotive circuits, reducing BOM count and board area.

Can PMEG2010EH replace older PMEG2010EJ in existing designs?

Yes - PMEG2010EH is a direct replacement for PMEG2010EJ with identical electrical specs, pinout, and SOD123F package. Key improvements include updated AEC-Q101 test reporting and enhanced process control; no layout or firmware changes are required for drop-in substitution.
