Nexperia USA Inc. PMEG050V150EPDZ

Overview

PMEG050V150EPDZ from Nexperia is a 50 V, 15 A planar MEGA Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and freewheeling in automotive-grade power supplies. It delivers 450 mV typical forward voltage at 15 A and 25 °C, operates up to 175 °C junction temperature, and is qualified to AEC-Q101.

For engineers reviewing the PMEG050V150EPDZ datasheet, PMEG050V150EPDZ pinout, PMEG050V150EPDZ application, or PMEG050V150EPDZ equivalent, key selection criteria include its ultra-low VF, clip-bonded thermal performance, CFP15 (SOT1289) package height of 0.78 mm, and reverse current ≤1000 µA at 50 V.

Technical Context

This Schottky rectifier uses planar MEGA technology with an integrated guard ring to enhance surge robustness and reduce leakage under transient stress. Its clip-bonding construction directly connects the die to the cathode tab, lowering thermal resistance to 3 K/W (junction-to-solder point) and enabling high-power handling in a thin SMD package.

The device exhibits negligible reverse recovery (trr ≤51 ns step, ≤20 ns ramp), near-zero Qrr, and diode capacitance of 570 pF at 10 V - characteristics critical for minimizing switching losses in high-frequency SMPS and synchronous rectification circuits.

Key Specifications

Pinout & Package

FAQ

What is the maximum allowable solder point temperature for PMEG050V150EPDZ during reflow?

The device is rated for a maximum solder point temperature (Tsp) of 155 °C under continuous DC operation and up to 160 °C for square-wave conditions with 50% duty cycle. Reflow profiles must limit peak temperature to ≤260 °C for ≤10 seconds to avoid delamination or bond degradation, per JEDEC J-STD-020.

Can PMEG050V150EPDZ replace a standard 1N5822 in a 5 V/10 A buck converter?

Yes - with caveats. PMEG050V150EPDZ offers lower VF (450 mV vs. ~550 mV), higher IF(AV) (15 A vs. 3 A), and superior thermal performance, but requires CFP15 footprint and reflow profile validation. Its dual-anode layout also demands updated PCB routing to maintain symmetry and minimize loop inductance.

Does the guard ring affect the device's reverse breakdown behavior?

Yes - the integrated guard ring suppresses premature edge breakdown, raising the effective V(BR)R to 50 V minimum (tested at 5 mA). This allows stable operation at VR = 50 V without derating, unlike non-guarded Schottkys that typically require 20% voltage margin to avoid localized avalanche.

How does thermal resistance change when mounted on FR4 vs. ceramic PCB?

Rth(j-a) drops from 90 K/W (standard FR4) to 40 K/W (Al₂O₃ ceramic), while Rth(j-sp) remains fixed at 3 K/W. The ceramic improvement comes from higher substrate conductivity - enabling 3.75 W total power dissipation at 25 °C ambient versus 1.66 W on standard FR4 - critical for unforced-air environments.
