Product details
Overview
PMEG045T100EPDAZ from Nexperia is a Trench MEGA Schottky barrier rectifier optimized for low-voltage, high-efficiency power conversion. It delivers 10 A average forward current at 45 V reverse voltage with an ultra-low 480 mV typical forward voltage at 10 A and 25 °C, enabled by clip-bonding thermal enhancement and CFP15B packaging. It serves as a freewheeling or reverse polarity protection diode in automotive DC-DC converters and industrial SMPS.
For engineers reviewing the PMEG045T100EPDAZ datasheet, PMEG045T100EPDAZ pinout, PMEG045T100EPDAZ application, or PMEG045T100EPDAZ equivalent, key selection criteria include its AEC-Q101 qualification, 0.95 mm profile, dual-anode cathode-terminal configuration, and junction-to-solder-point thermal resistance of 3 K/W - critical for thermally constrained automotive PCB layouts.
Technical Context
This Schottky rectifier uses trench-based silicon architecture to minimize forward voltage while maintaining 45 V blocking capability and sub-40 ns step-recovery time. Its dual-anode (pins 1 & 2) and single-cathode (pin 3) layout enables low-inductance current paths and efficient heat extraction via the exposed cathode tab.
The device operates up to 175 °C junction temperature and exhibits <80 µA reverse leakage at 45 V/25 °C, with thermal resistance from junction to solder point rated at 3 K/W when mounted on a 1 cm² cathode pad - enabling sustained 10 A operation under controlled board-level thermal management.
Key Specifications

FAQ
What is the maximum allowable solder point temperature for continuous operation?
The datasheet specifies that average forward current derates to 10 A only when solder point temperature (Tsp) remains ≤142 °C under δ = 0.5 duty cycle. At Tsp = 137 °C, peak forward current reaches 14 A. Exceeding 142 °C requires current reduction per Figure 10 curves to prevent thermal runaway.
Can PMEG045T100EPDAZ replace a standard through-hole Schottky in existing designs?
No direct drop-in replacement exists due to its CFP15B surface-mount footprint and dual-anode layout. Board redesign is required to accommodate the 5.8 × 4.3 mm outline, 2.13 mm pitch, and cathode thermal pad. Thermal simulation is recommended to validate PCB copper area meets the 1 cm² minimum requirement.
How does the dual-anode configuration affect PCB layout?
Pins 1 and 2 are internally shorted anodes, allowing symmetrical trace routing from both sides of the component. This reduces parasitic inductance in high-di/dt applications like buck converters and improves current sharing uniformity across the die - critical for minimizing localized heating at high IF(AV).
Is the 45 V reverse voltage rating suitable for 36 V automotive battery systems?
Yes. The 45 V VR rating provides 25% headroom above nominal 36 V battery voltage and accommodates load-dump transients up to 40 V defined in ISO 7637-2 Pulse 5a. Combined with AEC-Q101 qualification, it meets functional safety requirements for front-end rectification in automotive power modules.
