Nexperia USA Inc. PMEG45A10EPDZ

Overview

PMEG45A10EPDZ from Nexperia is a 45 V, 10 A low forward-voltage Schottky barrier rectifier in a thermally enhanced CFP15 (SOT1289) surface-mount package, featuring integrated guard ring stress protection and clip-bonding for high power capability. It delivers VF = 473 mV at 10 A (25 °C, pulsed), IR ≤ 500 µA at 45 V, and operates up to 150 °C junction temperature - optimized for low-loss DC-to-DC conversion in compact power supplies.

For engineers reviewing the PMEG45A10EPDZ datasheet, PMEG45A10EPDZ pinout, PMEG45A10EPDZ application, or PMEG45A10EPDZ equivalent, key selection criteria include forward voltage drop at rated current, thermal resistance to solder point (Rth(j-sp) = 4 K/W), reverse leakage at elevated temperature (11 mA at 125 °C/10 V), and SMT footprint compatibility with FR4 or ceramic PCBs.

Technical Context

This MEGA Schottky rectifier uses planar silicon construction with an integrated guard ring to suppress edge breakdown and improve reliability under repetitive surge stress. Its clip-bonded die attach and exposed cathode tab enable direct thermal coupling to PCB copper, supporting high average current (IF(AV) = 10 A) with minimal thermal derating on standard FR4 layouts.

The device exhibits ultrafast recovery (trr = 13 ns ramp, 21 ns step) and low capacitance (Cd = 240 pF at 10 V), making it suitable for high-frequency switching topologies where diode reverse recovery losses must be minimized. Reverse breakdown voltage (V(BR)R = 45 V) matches its rated VR, confirming tight process control without overrating margin.

FAQ

What is the maximum continuous forward current at 100 °C ambient temperature on a standard FR4 PCB?

At Tamb = 100 °C with standard FR4 mounting (single-sided copper, tin-plated, no extended pad), PMEG45A10EPDZ supports IF(AV) ≈ 5.2 A. This is derived from thermal resistance Rth(j-a) = 165 K/W and Tj(max) = 150 °C, yielding ΔT = 50 K and Ptot = 0.303 W - corresponding to ~5.2 A using VF ≈ 580 mV at elevated temperature.

Does PMEG45A10EPDZ require a thermal pad or vias for operation at full 10 A rating?

No thermal vias are required. The datasheet specifies 3 W total power dissipation on a ceramic PCB (Al₂O₃) and 1.2 W on FR4 with a 1 cm² cathode pad. At 10 A and VF = 0.5 V, power dissipation is 5 W - so full rating requires the ceramic PCB condition or active cooling; for FR4, derating to ≤6 A is recommended without extended copper.

How does the guard ring affect reverse voltage testing compliance?

The integrated guard ring prevents premature edge breakdown, allowing the device to sustain its full 45 V VR rating under IEC 61000-4-5 surge conditions and repeated 45 V reverse bias without parameter shift. Test data confirms V(BR)R = 45 V at 5 mA, matching VR - indicating guard ring effectiveness in suppressing localized field enhancement.

Can PMEG45A10EPDZ replace older PMEG45A10EP in existing designs?

Yes - PMEG45A10EPDZ is a qualified drop-in replacement for PMEG45A10EP, sharing identical electrical specs, pinout, package outline (SOT1289), and marking (4510). The 'Z' suffix denotes tape-and-reel packaging per AEC-Q200-compliant logistics - no circuit or layout changes are needed.
