Product details
Overview
PMEG045T030EPDZ from Nexperia is a 45 V, 3 A Trench MEGA Schottky barrier rectifier in CFP15 (SOT1289) package, designed for low-voltage, high-efficiency DC-to-DC conversion and freewheeling in automotive-grade power supplies. It delivers 420–480 mV forward voltage at 3 A and 25 °C, exhibits ≤44 µA reverse leakage at 45 V/25 °C, and is AEC-Q101 qualified for under-hood applications.
For engineers reviewing the PMEG045T030EPDZ datasheet, PMEG045T030EPDZ pinout, PMEG045T030EPDZ application, or PMEG045T030EPDZ equivalent, key selection criteria include low VF performance at high ambient temperatures, thermal resistance to solder point (Rth(j-sp) = 3 K/W), reverse recovery time (trr ≤ 24 ns), and AEC-Q101 qualification for automotive reliability validation.
Technical Context
This Schottky rectifier uses Trench MEGA technology to achieve low forward voltage and low leakage simultaneously-enabled by optimized metal-semiconductor interface and deep trench isolation. Its clip-bonded construction enhances thermal conduction from junction to cathode tab, supporting continuous 3 A average current with Tsp ≤ 168 °C on standard FR4 PCBs.
The device operates without minority-carrier storage, delivering step-recovery trr ≤ 24 ns and ramp-recovery trr ≤ 16 ns. Its diode capacitance drops from 830 pF at 1 V to 350 pF at 10 V reverse bias, enabling stable switching behavior in high-frequency SMPS topologies up to several MHz.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-3EYH04-M3/54 | 45 V, 3 A; VF = 490 mV @ 3 A; Rth(j-a) = 60 K/W; not AEC-Q101 qualified | Limited to industrial/commercial use; unsuitable for automotive due to missing qualification | Select only for cost-sensitive non-automotive designs where 70 mV higher VF is acceptable |
| ON Semiconductor NSR3450HT1G | 45 V, 3 A; VF = 450 mV @ 3 A; Rth(j-sp) = 4.5 K/W; AEC-Q101 qualified | Slightly higher thermal resistance requires larger copper area for same current rating | Prefer when existing layout supports larger thermal pad; avoid if board space restricts cathode copper area |
Compared with VS-3EYH04-M3/54 and NSR3450HT1G, PMEG045T030EPDZ offers the lowest VF (420 mV), best thermal performance (Rth(j-sp) = 3 K/W), and full AEC-Q101 compliance-making it optimal for space- and efficiency-constrained automotive power rails.

FAQ
What is the maximum junction temperature and how is it maintained?
The absolute maximum junction temperature is 175 °C. It is maintained through low Rth(j-sp) = 3 K/W thermal resistance to the solder point, enabled by clip-bonding and the exposed cathode pad. When mounted on a 1 cm² copper area per IPC-2221 guidelines, the device sustains 3 A average current with Tsp ≤ 168 °C at Tamb = 85 °C.
Is PMEG045T030EPDZ suitable for synchronous rectification in high-frequency converters?
Yes - its 24 ns step-recovery trr and 16 ns ramp-recovery trr minimize switching loss and voltage overshoot in converters operating up to 1 MHz. The low diode capacitance (350 pF at 10 V) further stabilizes gate drive behavior in GaN-based topologies.
How does the dual-anode pin configuration improve performance?
Pins 1 and 2 are both anodes, allowing symmetrical PCB routing to halve current density per trace and reduce parasitic inductance. This configuration lowers EMI and improves current sharing in high-dI/dt applications like motor drive freewheeling paths.
What is the significance of the "EPD" suffix in the part number?
The "EPD" suffix denotes Nexperia's Enhanced Power Dissipation variant within the CFP15 package family - indicating optimized clip-bonding, thicker copper leadframe, and thermal pad geometry that achieves Rth(j-sp) = 3 K/W versus 5–6 K/W in standard CFP15 Schottkys.
