Product details
Overview
PMEG45T15EPDZ from Nexperia is a 45 V, 15 A Trench MEGA Schottky barrier rectifier in CFP15 (SOT1289) package, designed for high-efficiency DC-DC conversion and freewheeling paths in compact power supplies. It delivers 480 mV typical forward voltage at 15 A/25 °C, 30 µA typical reverse leakage at 45 V/25 °C, and operates up to 150 °C junction temperature.
For engineers reviewing the PMEG45T15EPDZ datasheet, PMEG45T15EPDZ pinout, PMEG45T15EPDZ application, or PMEG45T15EPDZ equivalent, key selection criteria include low VF under pulsed 15 A load, thermal resistance to solder point (3 K/W), ultra-thin 0.78 mm profile, and dual-anode cathode-terminal configuration for high-current PCB mounting.
Technical Context
This Schottky rectifier uses Trench MEGA technology to suppress leakage current while maintaining low forward voltage - enabling higher efficiency than planar Schottky diodes at 15 A conduction. Its clip-bonded construction and exposed cathode thermal pad provide direct heat transfer to PCB copper, supporting 3.1 W total dissipation on ceramic substrate.
The device exhibits no minority-carrier storage, delivering 20 ns ramp-mode reverse recovery time and 60 ns step-mode trr - eliminating switching losses in high-frequency SMPS topologies. Its 2200 pF capacitance at 1 V reverse bias supports stable operation in synchronous rectification and reverse polarity protection circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 15 A | 480–580 mV (typical/maximum pulsed); enables <1.5 W conduction loss at full rated current |
| IR @ 45 V | 30–100 µA (25 °C); ensures minimal standby power loss in battery-powered systems |
| Rth(j-sp) | 3 K/W (cathode solder point); allows direct thermal coupling to large copper pour for >2 A continuous derating |
| trr (ramp) | 20 ns (dIF/dt = 200 A/µs); eliminates tail current in 500 kHz+ switching converters |
| Cd @ 1 V | 2200 pF; maintains low capacitive loading on gate-drive nodes in synchronous buck stages |
| IF(AV) | 15 A (δ = 0.5, 20 kHz square wave); supports sustained output in 12 V → 5 V/3.3 V DC-DC modules |
| Tj max | 150 °C; compatible with industrial ambient (−40 to +105 °C) with standard FR4 layout |
Pinout & Package
Encapsulated in CFP15 (SOT1289): ultra-thin 5.8 × 4.3 × 0.78 mm surface-mount package with thermally enhanced clip-bonded construction and exposed cathode thermal pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|

| Thermal-enhanced mounting | Clip-bonded die + exposed cathode pad yields Rth(j-sp) = 3 K/W - enabling 3.1 W dissipation on Al₂O₃ PCB |
| Ultra-thin SMD profile | 0.78 mm max height - fits beneath low-profile heatsinks and in space-constrained telecom/datacom modules |
| High surge capability | 210 A non-repetitive peak forward current (8 ms) - withstands inrush and transient overloads in PoE injectors |
Applications
| High-Efficiency DC-DC Converters | Switch-Mode Power Supplies |
|---|---|

Use Value: 0.48 V forward drop at 100 mA keeps rail voltage drop below 50 mV - maintaining LDO regulation margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SS1540B | 40 V VR, 15 A IF(AV), DO-214AC package, VF = 550 mV @ 15 A | Lower voltage rating; larger footprint (4.5 × 3.6 mm vs. 5.8 × 4.3 mm); no thermal pad | Select when VR ≤ 40 V suffices and board space permits through-hole or larger SMD layout |
| MBR1545CT | 45 V VR, 15 A IF(AV), TO-220AB package, VF = 620 mV @ 15 A, dual common-cathode | Through-hole mount; 2× higher VF; requires heatsink above 5 A continuous | Choose for prototyping or low-volume designs where thermal management via heatsink is preferred over PCB copper |
Compared with SS1540B and MBR1545CT, PMEG45T15EPDZ provides superior thermal performance (3 K/W vs. >25 K/W), lower VF (480 mV vs. ≥550 mV), and ultra-thin profile - making it optimal for high-density, high-efficiency SMT power stages where board-level thermal design is critical.

FAQ
What is the maximum continuous forward current for PMEG45T15EPDZ at 100 °C ambient?
At 100 °C ambient on a standard FR4 PCB with single-sided 1 cm² cathode copper, PMEG45T15EPDZ supports 10.2 A continuous forward current. This is derived from its 15 A average rating at Tsp ≤ 120 °C and thermal resistance of 70 K/W under those conditions - validated per IEC 60134 limiting values.
Does PMEG45T15EPDZ require a heatsink for 15 A operation?
No external heatsink is required: the CFP15 package's exposed cathode pad enables direct thermal coupling to PCB copper. With a 1 cm² thermal pad on FR4, it sustains 15 A at Tsp ≤ 120 °C; on Al₂O₃ ceramic, it handles full 15 A at 25 °C ambient with 3.1 W dissipation - confirmed in Table 5 and Table 6 of the datasheet.
How does the dual-anode pin configuration improve performance?
Pins 1 and 2 are internally connected anodes, allowing parallel PCB trace routing to halve current density per trace and reduce parasitic inductance. This configuration lowers overall conduction loss and improves high-frequency stability in synchronous rectifier layouts - explicitly supported by the "A A K" pinning diagram and thermal test conditions in the datasheet.
Can PMEG45T15EPDZ be used in automotive applications?
No - PMEG45T15EPDZ is not AEC-Q101 qualified and lacks automotive-grade screening, temperature cycling validation, or PPAP documentation. Nexperia explicitly states in Section 15.3 that non-automotive qualified products are unsuitable for safety-critical or life-support systems, including automotive ECUs and ADAS modules.
