Nexperia USA Inc. PMEG045V100EPEZ

Overview

PMEG045V100EPEZ from Nexperia is a 45 V, 10 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) thermally enhanced ultra-thin SMD package. It delivers 450–490 mV forward voltage at 10 A and 25 °C, supports 300 A non-repetitive peak forward current, and enables high-efficiency DC-to-DC conversion in space-constrained power rails.

For engineers reviewing the PMEG045V100EPEZ datasheet, PMEG045V100EPEZ pinout, PMEG045V100EPEZ application, or PMEG045V100EPEZ equivalent, key selection criteria include low VF performance at high ambient temperatures, thermal resistance to solder point (3 K/W), reverse recovery time (≤36 ns), and compatibility with FR4 PCBs using standard or enhanced cathode pad footprints.

Technical Context

This Schottky rectifier uses clip-bond technology to achieve high power capability and low thermal resistance - R_th(j-sp) = 3 K/W - by direct metal attachment of the die to the cathode tab. Its planar structure ensures stable reverse leakage (<600 µA at 45 V, 25 °C) and minimal capacitance (375 pF at 10 V).

The device operates across –40 °C to +175 °C junction temperature, with VF increasing only modestly to 570 mV at –40 °C (10 A) and dropping to 390 mV at 125 °C (10 A), enabling robust performance in wide-temperature industrial and telecom power supplies.

FAQ

What is the maximum allowable solder point temperature for PMEG045V100EPEZ during reflow?

The device is rated for a maximum solder point temperature (T_sp) of 174 °C under δ = 0.5 square-wave conditions. Reflow profiles must ensure peak temperature at the cathode tab does not exceed this limit; Nexperia recommends using the CFP15B footprint in Figure 16 with 0.125 mm stencil thickness for controlled thermal mass.

Can PMEG045V100EPEZ be used in automotive applications?

No - PMEG045V100EPEZ is not AEC-Q200 qualified and is explicitly designated for industrial and commercial use per Nexperia's legal disclaimers. It has not undergone automotive-grade stress testing, and its reliability data does not cover extended temperature cycling or vibration requirements mandated for automotive ECUs or ADAS power rails.

How does the dual-anode configuration affect PCB layout?

The dual-anode (Pins 1 and 2) design allows symmetric high-current routing: both pins must be connected to the same net with equal-length, wide copper traces to balance current distribution and minimize inductive imbalance. This reduces EMI and thermal skew compared to single-anode alternatives in high-di/dt applications.

Is there a recommended minimum copper area for the cathode pad?

Yes - for optimal thermal performance, Nexperia specifies a 1 cm² tin-plated copper pad under the cathode (Pin 3) to achieve the 2.15 W P_tot rating and 3 K/W R_th(j-sp). Using less than 1 cm² reduces safe operating current significantly; Figure 9 shows I_F(AV) drops to ~7.5 A at 25 °C ambient with smaller pads.
