Product details
Overview
PMEG050V150EPD from Nexperia is a 50 V, 15 A planar MEGA Schottky barrier rectifier in a CFP15 (SOT1289) surface-mount package, featuring integrated guard ring stress protection and clip-bonding for high thermal performance. It delivers extremely low forward voltage (450–500 mV at 15 A, 25 °C), supports automotive-grade reliability (AEC-Q101 qualified), and is optimized for low-voltage, high-efficiency DC-to-DC conversion in power supplies and freewheeling circuits.
For engineers reviewing the PMEG050V150EPD datasheet, PMEG050V150EPD pinout, PMEG050V150EPD application, or PMEG050V150EPD equivalent, key selection criteria include its 50 V reverse voltage rating, 15 A average forward current capability, sub-0.5 V forward voltage at full load, 175 °C junction temperature limit, and thermal resistance of 3 K/W from junction to solder point - all critical for compact, thermally constrained power designs.
Technical Context
This Schottky rectifier uses a planar MEGA structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reverse leakage stability. Its clip-bonding interconnect and exposed cathode tab enable direct heat transfer to the PCB, supporting high-power operation in ultra-thin SMD form factor (0.78 mm typical height).
The device exhibits fast switching behavior with ramp-mode reverse recovery time of 20 ns and step-mode trr of 51 ns, plus low diode capacitance (570 pF at 10 V), making it suitable for high-frequency SMPS topologies where conduction loss and switching loss trade-offs are critical.
Key Specifications

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-15EWH05-M3 | Same 50 V VR, 15 A IF(AV), but TO-252 (DPAK) package; VF = 490 mV @ 15 A; Rth(j-a) = 45 K/W (vs. 40 K/W for PMEG050V150EPD on ceramic PCB). | Requires larger PCB footprint and lacks AEC-Q101 qualification; better suited for cost-sensitive industrial supplies than automotive. | Select when DPAK mounting is preferred and AEC-Q101 is not required; avoid in space-constrained or automotive designs. |
| ON Semiconductor NSR15H50HT1G | 50 V, 15 A, VF = 470 mV @ 15 A, SOD-123FL package; Rth(j-a) = 110 K/W; no AEC-Q101 rating; trr = 35 ns. | Limited thermal performance and lower surge rating (IFSM = 120 A); intended for low-power consumer adapters, not high-reliability or high-current use. | Only consider for prototyping or low-volume non-automotive applications where footprint size is secondary to cost. |
Compared with VS-15EWH05-M3 and NSR15H50HT1G, the PMEG050V150EPD offers superior thermal performance (3 K/W Rth(j-sp)), AEC-Q101 qualification, and ultra-thin CFP15 packaging - making it the only option among the three viable for production automotive power modules requiring both high current density and long-term reliability.

FAQ
What is the maximum junction temperature rating for the PMEG050V150EPD?
The PMEG050V150EPD has a maximum junction temperature (Tj) rating of 175 °C, as specified in the Absolute Maximum Ratings table. This allows sustained operation in high-ambient environments such as under-hood automotive locations or enclosed industrial enclosures, provided thermal design maintains Tj ≤ 175 °C under worst-case load and ambient conditions. The PMEG050V150EPD datasheet confirms this value applies across all operating conditions.
Does the PMEG050V150EPD support automotive qualification standards?
Yes, the PMEG050V150EPD is qualified to AEC-Q101 for discrete semiconductors, as explicitly stated in Section 11.1 of the official Nexperia datasheet. This qualification covers stress tests including HTGB, HTRB, AC-HAST, and temperature cycling, confirming suitability for automotive powertrain, chassis, and body electronics applications. The PMEG050V150EPD meets these requirements without derating.
How many anode terminals does the PMEG050V150EPD have, and why?
The PMEG050V150EPD has two anode terminals (Pins 1 and 2), both electrically connected to the same internal anode structure. This dual-anode configuration reduces current path inductance and improves current sharing in high-frequency, high-current layouts - especially beneficial in compact DC/DC converters where loop area minimization is critical for EMI control. The PMEG050V150EPD pinning diagram confirms identical anode labeling for both pins.
What is the thermal resistance from junction to solder point (Rth(j-sp)) for the PMEG050V150EPD?
The PMEG050V150EPD has a thermal resistance from junction to solder point (Rth(j-sp)) of 3 K/W, measured at the cathode tab solder joint under standard test conditions. This low value reflects the device's clip-bonding construction and exposed cathode thermal pad, enabling efficient heat transfer directly into the PCB copper. The PMEG050V150EPD datasheet specifies this parameter in Table 6 under "Rth(j-sp)" with footnote [5] identifying the cathode tab as the measurement point.
Can the PMEG050V150EPD be used in reverse polarity protection circuits?
Yes, the PMEG050V150EPD is explicitly listed in the Applications section for reverse polarity protection. Its low forward voltage (≤500 mV at 15 A) minimizes insertion loss, while its 50 V reverse voltage rating provides adequate headroom for 24 V automotive or industrial systems. The PMEG050V150EPD's AEC-Q101 qualification and robust guard ring further ensure reliability in harsh electrical environments where transients and load dumps occur.
