Nexperia USA Inc. PMEG6020AELRX

Overview

PMEG6020AELRX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-leakage, high-efficiency DC-to-DC conversion and reverse polarity protection in space-constrained SMD applications. It delivers 2 A average forward current at 60 V reverse voltage, 600 mV forward voltage at 2 A, 235 nA reverse leakage at 60 V/25 °C, and operates up to 175 °C junction temperature in the SOD123W (CFP3) package.

For engineers reviewing the PMEG6020AELRX datasheet, PMEG6020AELRX pinout, PMEG6020AELRX application, or PMEG6020AELRX equivalent, key selection criteria include ultra-low IR for standby power integrity, thermal robustness on FR4 PCBs, clip-bonding–enabled power handling, and compatibility with high-frequency switching topologies requiring fast recovery (trr = 9 ns) and minimal capacitive loading (Cd = 88 pF at 10 V).

Technical Context

This Schottky diode uses a planar silicon die with integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF and ultra-low IR stem from optimized metal–semiconductor interface engineering and precise doping control, enabling stable operation across −40 °C to 175 °C junction temperatures.

The device employs clip-bonding interconnect technology instead of traditional wire bonding, reducing thermal resistance (Rth(j-sp) = 18 K/W to cathode solder point) and enhancing surge current capability (IFSM = 50 A). Its 9 ns reverse recovery time and sub-100 pF capacitance support efficient operation in 20 kHz+ switch-mode power supplies.

FAQ

What is the maximum allowable solder point temperature for PMEG6020AELRX during reflow?

The device is rated for a maximum solder point temperature (Tsp) of 165 °C under δ = 0.5 duty cycle conditions, with absolute maximum Tsp = 200 °C per limiting values. Reflow profiles must ensure peak temperature at the cathode solder point does not exceed 165 °C for sustained reliability; Nexperia recommends using the CFP3 footprint in Figure 17 with 0.1 mm stencil thickness.

How does the guard ring affect voltage derating in humid or contaminated environments?

The integrated guard ring physically isolates the active junction periphery, suppressing surface leakage paths and preventing premature avalanche at chip edges. This allows full 60 V VR rating to be maintained without additional derating in IPC Class 2 or 3 humidity environments, unlike non-guarded Schottkys that typically require ≥20% VR margin under condensation.

Can PMEG6020AELRX replace standard 1N5819-type diodes in existing designs?

Yes-with verified layout adaptation. It offers lower VF (600 mV vs. ~750 mV), 10× lower IR (235 nA vs. ~2 µA), and superior thermal resistance (Rth(j-sp) = 18 K/W vs. >40 K/W for DO-214AC parts). However, its SOD123W footprint requires PCB land pattern revision; thermal relief pads must match Nexperia's recommended 1.2 mm × 1.4 mm cathode pad.

Is PMEG6020AELRX qualified for automotive applications?

No. Per Nexperia's revision history (v.5, Jan 2023), this part is explicitly non-automotive qualified. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia offers the PMEG6020AELRX-Q variant-identical electrical specs but with full AEC-Q101 qualification and extended temperature screening.
