Nexperia USA Inc. PMEG3020CERX

Overview

PMEG3020CERX from Nexperia is a planar Schottky barrier rectifier in CFP3 (SOD123W) surface-mount package, rated for 30 V reverse voltage and 2 A average forward current at T_sp ≤ 167 °C. It delivers low forward voltage (460–520 mV @ 2 A, 25 °C), ultra-low reverse recovery time (5.5 ns), and high thermal robustness (T_j = 175 °C), enabling use in high-efficiency DC-DC converters and reverse polarity protection circuits.

For engineers reviewing the PMEG3020CERX datasheet, PMEG3020CERX pinout, PMEG3020CERX application, or PMEG3020CERX equivalent, key selection criteria include forward voltage drop at 2 A load, thermal resistance to solder point (130 K/W), reverse leakage at 125 °C (8–25 mA), and compatibility with standard SOD123W reflow footprints.

Technical Context

This Schottky rectifier uses a planar metal-semiconductor junction optimized for minimal conduction loss and negligible minority-carrier storage. Its clip-bond construction enhances power handling while maintaining a 1 mm profile and 2.6 mm × 1.7 mm footprint.

The device exhibits temperature-stable VF characteristics - dropping to 380–470 mV at 125 °C junction temperature - and features low diode capacitance (145 pF @ 1 V, 1 MHz), supporting high-frequency switching up to several MHz in SMPS topologies.

FAQ

What is the maximum allowable solder point temperature for continuous operation?

The datasheet specifies an absolute maximum solder point temperature (T_sp) of 167 °C for 2 A average forward current at 50% duty cycle. Exceeding this value risks accelerated degradation of the clip bond interface and long-term reliability loss. Thermal design must ensure T_sp remains ≤165 °C under worst-case ambient and airflow conditions.

Can PMEG3020CERX replace a standard PN-junction diode in an existing 24 V SMPS design?

Yes - with verified benefits: its 5.5 ns t_rr eliminates reverse recovery spikes, reducing EMI filter requirements, and its 460 mV V_F cuts conduction loss by ~65% versus a typical 1N5822. However, layout must accommodate the SOD123W footprint and ensure cathode pad thermal relief matches the 1 cm² recommendation for optimal R_th(j-sp).

How does reverse leakage behave at elevated temperatures?

At 125 °C junction temperature and 30 V reverse bias, IR is specified at 8–25 mA - over 500× higher than the 15–50 µA at 25 °C. This increase is inherent to Schottky physics and must be accounted for in high-temperature reverse-bias applications, such as hold-up capacitors or floating supplies, where leakage could affect standby power.

Is the marking "N4" sufficient to identify PMEG3020CERX on the board?

Yes - per Table 4 of the datasheet, "N4" is the official top-side marking for PMEG3020CERX. The bar adjacent to pin 1 denotes the cathode, confirming orientation. No secondary marking or date code is required for functional identification; automated optical inspection systems can reliably detect both the "N4" laser mark and cathode bar.
