Nexperia USA Inc. PMEG045T150EIPDZ

Overview

PMEG045T150EIPD from Nexperia is a 45 V, 15 A Trench MEGA Schottky barrier rectifier in CFP15 (SOT1289) package, designed for low-voltage, high-efficiency DC-to-DC conversion and freewheeling in automotive-grade power supplies. It delivers 510–570 mV forward voltage at 15 A/25 °C, <98 µA reverse leakage at 45 V/25 °C, and is AEC-Q101 qualified for under-hood applications.

For engineers reviewing the PMEG045T150EIPD datasheet, PMEG045T150EIPD pinout, PMEG045T150EIPD application, or PMEG045T150EIPD equivalent, key selection criteria include low VF stability across −40 °C to 125 °C, thermal resistance as low as 3 K/W (junction-to-solder-point), and clip-bonded construction enabling 21 A continuous forward current on FR4 PCB with cathode pad.

Technical Context

This Schottky rectifier employs Trench MEGA technology to suppress reverse leakage while maintaining ultra-low forward voltage-critical for minimizing conduction loss in synchronous buck converters and OR-ing circuits. Its dual-anode, single-cathode configuration supports high-current routing with reduced parasitic inductance.

The CFP15 package integrates a thermally enhanced clip-bonded structure and a 1 cm² cathode thermal pad, achieving R_th(j-sp) = 3 K/W and enabling 2.15 W total power dissipation at 25 °C ambient. Transient thermal impedance data confirms stable operation under pulsed loads up to 130 A (8 ms).

FAQ

What is the maximum allowable solder point temperature for PMEG045T150EIPD during reflow?

The device is rated for a maximum solder point temperature (T_sp) of 118 °C under continuous operation. Reflow profiles must ensure peak temperature at the cathode tab does not exceed this limit; Nexperia recommends using the CFP15-specific footprint in Figure 15 with controlled thermal mass to avoid localized overheating during assembly.

Does PMEG045T150EIPD support bidirectional current flow?

No-it is a unidirectional Schottky rectifier with anode (Pins 1 & 2) and cathode (Pin 3) terminals. Reverse conduction is blocked above its 45 V rating, and intentional reverse bias beyond limiting values causes permanent damage per IEC 60134 absolute maximum ratings.

How does the dual-anode configuration improve thermal performance?

The dual-anode (Pins 1 & 2) provides parallel current paths that reduce effective series resistance and distribute current density across two bond interfaces, lowering localized heating and improving current sharing-especially beneficial during high-pulse transient conditions like motor startup or load dump.

Can PMEG045T150EIPD be used in a synchronous rectification topology?

Yes-its low V_F, fast t_rr (21 ns), and low Q_r make it suitable as a self-driven synchronous rectifier in flyback or forward converters where gate drive complexity must be avoided. However, it cannot replace actively controlled MOSFETs in high-side synchronous configurations requiring bidirectional control.
