Nexperia USA Inc. PMEG45U10EPDZ

Overview

PMEG45U10EPDZ from Nexperia is a 45 V, 10 A extremely low forward-voltage Schottky barrier rectifier in a thermally enhanced CFP15 (SOT1289) surface-mount package. It features an integrated guard ring for stress protection, clip-bonding technology for high power capability, and a typical height of only 0.78 mm - optimized for low-voltage rectification and high-efficiency DC-DC conversion in space-constrained power supplies.

For engineers reviewing the PMEG45U10EPDZ datasheet, PMEG45U10EPDZ pinout, PMEG45U10EPDZ application, or PMEG45U10EPDZ equivalent, key selection criteria include its 430–490 mV forward voltage at 10 A, 230–600 µA reverse leakage at 45 V, 180 A non-repetitive peak forward current, thermal resistance as low as 3 K/W (junction-to-solder point), and suitability for freewheeling and reverse polarity protection circuits.

Technical Context

This MEGA Schottky rectifier uses planar silicon construction with an integrated guard ring to improve ruggedness against voltage transients and ESD stress. Its low VF stems from optimized metal-semiconductor interface design and clip-bonding, which reduces bond wire inductance and enhances current sharing across dual anode terminals.

The device operates with zero minority-carrier storage, delivering nanosecond-scale reverse recovery (trr = 16–34 ns) and negligible forward recovery voltage (VFRM ≤ 300 mV). Thermal performance is engineered for direct cathode tab soldering to PCB copper, enabling up to 3.1 W total power dissipation on ceramic substrates.

FAQ

What is the maximum allowable junction temperature for PMEG45U10EPDZ?

The absolute maximum junction temperature is 150 °C, as defined in the limiting values table. Continuous operation above this threshold risks permanent parametric shift and accelerated degradation. Derating curves in the datasheet show that at 130 °C case temperature, the device sustains 10 A average forward current with 50% duty cycle square-wave excitation - confirming safe operation in thermally demanding environments when properly mounted.

Can Pins 1 and 2 be used independently?

No - Pins 1 and 2 are internally connected anodes and must be tied to the same potential. Using them separately violates the device's electrical and thermal design, causing unbalanced current sharing, localized overheating, and premature failure. The dual-anode structure is intended solely to reduce effective series resistance and improve thermal spreading under high-current conditions.

Is PMEG45U10EPDZ suitable for automotive applications?

PMEG45U10EPDZ is not AEC-Q101 qualified and is explicitly designated as non-automotive in Nexperia's legal disclaimers. While its 45 V rating and guard ring provide robustness, it lacks automotive-grade qualification testing (e.g., extended temperature cycling, board-level reliability, and zero-defect screening). For automotive infotainment or body control modules, only AEC-Q101-certified equivalents should be selected.

How does the cathode tab thermal connection affect power dissipation?

Soldering the exposed cathode tab to ≥1 cm² of copper on an FR4 PCB reduces Rth(j-a) from 90 K/W to 40 K/W; using a ceramic Al₂O₃ substrate further lowers it to 70 K/W, and direct solder-point attachment achieves Rth(j-sp) = 3 K/W. This 30× improvement over standard SMD packages allows 3.1 W total power dissipation - enabling operation at full 10 A load without external heatsinking in compact power designs.
