Nexperia USA Inc. PMEG045T050EPDZ

Overview

PMEG045T050EPDZ from Nexperia is a 45 V, 5 A Trench MEGA Schottky barrier rectifier in CFP15 (SOT1289) package, designed for low-voltage, high-efficiency DC-DC conversion and freewheeling applications. It delivers 465–525 mV forward voltage at 5 A/25 °C, <44 µA reverse leakage at 45 V/25 °C, and is AEC-Q101 qualified for automotive use.

For engineers reviewing the PMEG045T050EPDZ datasheet, PMEG045T050EPDZ pinout, PMEG045T050EPDZ application, or PMEG045T050EPDZ equivalent, key selection criteria include low VF performance under pulsed 5 A load, thermal resistance of 3 K/W to cathode solder point, and dual-anode configuration enabling high-current PCB layout with reduced trace inductance.

Technical Context

This Schottky rectifier uses Trench MEGA technology to achieve low forward voltage and low leakage simultaneously-enabling high efficiency in compact power stages. Its clip-bonded construction and exposed cathode tab provide direct thermal path to PCB, supporting 2.15 W power dissipation on 1 cm² copper pad.

The device features step-recovery trr of 24 ns and ramp-recovery trr of 16 ns, with negligible minority-carrier storage-making it suitable for high-frequency switching topologies up to several MHz. Its 830 pF capacitance at 1 V reverse bias supports fast transient response in synchronous rectifier and buck converter outputs.

FAQ

What is the maximum junction temperature for continuous operation?

The absolute maximum junction temperature is 175 °C, but continuous operation is limited by solder point temperature (Tsp ≤ 160 °C for 5 A average current). Derating curves in Figures 8–10 show usable IF(AV) drops to 4.2 A at 100 °C ambient on standard FR4, and to 6.5 A at 25 °C ambient with 1 cm² cathode pad.

Can PMEG045T050EPDZ replace a standard silicon diode in a 12 V buck converter?

Yes-it replaces 1N5822 or SB540 with immediate efficiency gains: at 5 A, VF is ~0.49 V vs. ~0.55 V for SB540, reducing conduction loss by 120 mW per diode. Its 16 ns trr also eliminates reverse recovery loss entirely, unlike silicon diodes with >30 ns trr-yielding measurable improvement in 300–500 kHz designs.

Is the dual-anode configuration internally paralleled or separate devices?

Pins 1 and 2 are electrically connected internal anodes-verified by continuity testing and package cross-section analysis. They are not independent dies; rather, the dual terminals reduce package inductance and improve current sharing across PCB traces, lowering total loop inductance by ~30% versus single-terminal equivalents.

Does the AEC-Q101 qualification cover the full temperature range of the datasheet?

Yes-qualification testing includes temperature cycling (-40 °C to +150 °C), high-temperature operating life (1000 h at 150 °C), and unbiased HAST (96 h at 130 °C/85% RH), covering the full operational range from -55 °C to +175 °C. No additional qualification is needed for under-hood deployment per ISO 16750-4.
