Nexperia USA Inc. PMEG045T150EPDZ

Overview

PMEG045T150EPD from Nexperia is a 45 V, 15 A Trench MEGA Schottky barrier rectifier in CFP15 (SOT1289) package, designed for high-efficiency DC-to-DC conversion and freewheeling in automotive-grade power supplies. It delivers 480–550 mV forward voltage at 15 A/25 °C, 30–100 µA reverse leakage at 45 V/25 °C, and is AEC-Q101 qualified for under-hood applications.

For engineers reviewing the PMEG045T150EPD datasheet, PMEG045T150EPD pinout, PMEG045T150EPD application, or PMEG045T150EPD equivalent, key selection criteria include low VF performance at high current, thermal resistance to solder point (3 K/W), clip-bonded construction for power density, and validated operation up to 175 °C junction temperature.

Technical Context

This Schottky rectifier employs Trench MEGA technology to suppress leakage while maintaining ultra-low forward voltage-enabling higher efficiency than planar Schottkys at 10–15 A loads. Its dual-anode, single-cathode configuration supports parallel anode routing on PCBs for reduced trace inductance and improved thermal spreading.

The CFP15 package integrates a thermally enhanced copper clip-bonded structure with a 0.78 mm profile and exposed cathode tab, delivering R_th(j-sp) = 3 K/W to the solder point-critical for sustained 15 A average current in space-constrained automotive modules.

FAQ

What is the maximum allowable solder point temperature during reflow for PMEG045T150EPD?

The device is qualified for standard lead-free reflow profiles with peak temperature up to 260 °C for 30 seconds. The cathode solder point must remain below 260 °C to avoid delamination of the clip-bond structure. Reflow footprint per Figure 18 (SOT1289) ensures uniform heating and void-free solder joints.

Can PMEG045T150EPD be used in synchronous rectification circuits?

No-it is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. It functions as a unidirectional freewheeling or output rectification element only. For synchronous designs, a gate driver IC paired with a low-R_DS(on) MOSFET is required.

How does the dual-anode configuration affect PCB layout?

Pins 1 and 2 are internally shorted anodes, enabling symmetrical current injection from both ends of the package. This reduces loop inductance and improves thermal symmetry-layout should route equal-width traces to both pins and maintain identical copper pour area beneath each anode pad.

Is the 15 A rating valid at 125 °C junction temperature?

Yes-the 15 A IF(AV) rating is specified at δ = 0.5, f = 20 kHz, and T_sp ≤ 145 °C. At T_j = 125 °C, VF drops to 405 mV (typical), improving efficiency, but derating applies if ambient exceeds 85 °C or thermal resistance increases beyond design targets.
