Nexperia USA Inc. PMEG050V030EPEZ

Overview

PMEG050V030EPEZ from Nexperia is a 50 V, 3 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) surface-mount package, designed for high-efficiency DC-to-DC conversion and low-voltage rectification where minimal conduction loss is critical. It delivers VF = 460–530 mV at 3 A and 25 °C, IR ≤ 100 µA at 50 V, and supports freewheeling and OR-ing functions in compact power supplies.

For engineers reviewing the PMEG050V030EPEZ datasheet, PMEG050V030EPEZ pinout, PMEG050V030EPEZ application, or PMEG050V030EPEZ equivalent, key selection criteria include forward voltage at rated current, thermal resistance to solder point (Rth(j-sp) = 3 K/W), reverse leakage at operating temperature, and clip-bonded package power handling for sustained 3 A average current.

Technical Context

This Schottky rectifier uses planar die construction with copper clip-bonding to minimize parasitic inductance and enhance thermal transfer from junction to cathode tab. Its ultra-thin CFP15B package enables high power density while maintaining low Rth(j-sp) of 3 K/W when mounted on a 1 cm² cathode pad.

The device exhibits step-recovery trr ≤ 12 ns and ramp-recovery trr ≤ 10 ns under defined test conditions, with diode capacitance Cd = 323 pF at VR = 1 V and 113 pF at VR = 10 V - enabling fast switching in synchronous rectifier and freewheeling topologies without excessive capacitive turn-on loss.

Key Specifications

Pinout & Package

FAQ

What is the maximum average forward current for PMEG050V030EPEZ under real-world PCB conditions?

The PMEG050V030EPEZ supports 3 A average forward current (IF(AV)) when mounted on an FR4 PCB with a 1 cm² cathode pad and solder point temperature (Tsp) held ≤174 °C using δ = 0.5 square-wave excitation at 20 kHz. This reflects actual thermal limits-not idealized free-air ratings-and aligns with typical 4-layer board layouts using 2 oz copper.

How does the CFP15B package improve thermal performance over standard SOD-123 or SMA packages?

The CFP15B package uses copper clip-bonding to directly connect the die cathode to an exposed metal tab, achieving Rth(j-sp) = 3 K/W-over 3× better than SOD-123 (≈10 K/W). This enables >2 W power dissipation with minimal PCB copper, whereas standard packages require large thermal pads or vias to achieve comparable cooling.

Can PMEG050V030EPEZ be used in place of a MOSFET-based synchronous rectifier?

Yes, but only where VF advantage outweighs gate-drive complexity. At 3 A and 25 °C, its 460–530 mV drop matches many 30 V MOSFETs in conduction loss, with zero gate drive overhead. However, it lacks active control-so it cannot block reverse current like a MOSFET in bidirectional topologies or provide programmable timing.

What is the significance of the "EPEZ" suffix in the part number?

The "EPEZ" suffix denotes Nexperia's tape-and-reel packaging variant for automated SMT assembly: 3,000 units per reel, 12 mm tape width, EIA-481-compliant embossed carrier tape, and RoHS-compliant matte tin lead finish. It does not indicate a parametric or functional revision versus the base PMEG050V030EPE part.
