Product details
Overview
PMEG050V150EPDAZ from Nexperia is a 50 V, 15 A low forward voltage MEGA Schottky barrier rectifier in a CFP15 (SOT1289) surface-mount package with integrated guard ring for stress protection. It delivers 450 mV typical forward voltage at 15 A and 25 °C, supports 240 A non-repetitive peak forward current, and is AEC-Q101 qualified for automotive power rail protection and DC-DC freewheeling.
For engineers reviewing the PMEG050V150EPDAZ datasheet, PMEG050V150EPDAZ pinout, PMEG050V150EPDAZ application, or PMEG050V150EPDAZ equivalent, this device is selected for low-loss rectification in space-constrained, thermally demanding environments where VF minimization and junction temperature stability up to 175 °C are critical.
Technical Context
This Schottky rectifier uses planar MEGA technology with an integrated guard ring to suppress edge breakdown and improve surge robustness. Its clip-bonded construction enhances thermal conduction from the die to the cathode tab, enabling high power dissipation (3.75 W on ceramic PCB) despite its ultra-thin 0.78 mm profile.
The device exhibits negligible reverse recovery (trr ≤ 51 ns step, ≤ 20 ns ramp), near-zero Qrr, and low diode capacitance (570 pF at 10 V), making it suitable for high-frequency switching topologies. Reverse leakage remains under 1000 µA at 50 V and 25 °C, with thermal runaway mitigation designed into the layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 15 A | 450–500 mV at 25 °C: enables <1.5 W conduction loss in 12 V/15 A output rails |
| VR | 50 V maximum reverse voltage: supports 36 V automotive nominal systems with margin |
| IF(AV) | 15 A average forward current: rated for continuous operation at Tsp ≤ 160 °C on FR4 |
| trr (step) | ≤ 51 ns: eliminates switching node oscillation in synchronous buck freewheel paths |
| Rth(j-sp) | 3 K/W: direct thermal path from junction to cathode solder point enables efficient heat extraction |
| IR @ 50 V | 260–1000 µA at 25 °C: low leakage preserves efficiency in standby and light-load conditions |
| AEC-Q101 | Qualified: validated for automotive under-hood applications including engine control and ADAS power supplies |
Pinout & Package
Encapsulated in a thermally enhanced CFP15 (SOT1289) plastic SMD package measuring 5.8 × 4.3 × 0.78 mm, with exposed cathode tab for heatsinking. The package features dual anode leads and one cathode terminal for low-inductance, high-current routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary high-current input path; electrically tied to Pin 2 for parallel conduction |
| 2 | Anode | Second anode terminal-bonded internally to Pin 1 to halve effective series resistance |
| 3 | Cathode | Thermally and electrically dominant terminal; large copper tab for solder-point thermal transfer |
Key Features
| Feature | Design Value |

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/15 A rating but TO-252 package (2.3 mm height); VF = 490 mV typ. at 15 A | Larger footprint and higher profile limit use in ultra-thin automotive modules | Select when board-level thermal mass exceeds 1 cm² copper and height >2 mm is acceptable |
| ON Semiconductor NSR15F50HT1G | CFP15 package, but VF = 520 mV typ. at 15 A; not AEC-Q101 qualified | Not approved for automotive under-hood deployment; lower surge robustness | Acceptable for industrial DC-DC where qualification is not mandated and 70 mV VF penalty is tolerable |
Compared with VS-15EWH05-M3 and NSR15F50HT1G, PMEG050V150EPDAZ offers the lowest VF in a qualified ultra-thin package, delivering superior thermal performance and automotive compliance without footprint or height trade-offs.

FAQ
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature is 175 °C, and the device is rated for continuous IF(AV) = 15 A at solder point temperature ≤160 °C on FR4 PCB with standard footprint. Derating curves in Figure 9 confirm 12 A average current is sustainable at 100 °C ambient on FR4 with 0.5 duty cycle.
Does PMEG050V150EPDAZ support synchronous rectification replacement?
No-it is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. However, its 20 ns ramp trr and low Qrr make it ideal as a freewheeling diode in synchronous buck topologies where the high-side switch is actively controlled and the low-side path benefits from zero-recovery behavior.
How does the guard ring affect surge performance?
The integrated guard ring redistributes electric field at the silicon periphery, preventing premature edge breakdown during repetitive 40 V load dump transients. This extends time-to-failure under ISO 7637-2 Pulse 5a stress by >3× compared to non-guarded equivalents, as verified in AEC-Q101 HBM and TLP testing.
Can this diode be used in parallel configurations?
Yes-dual anode terminals (Pins 1 and 2) are internally shorted, enabling symmetric current sharing when paralleled with identical devices. Layout must ensure matched thermal paths and equal trace inductance; derating to 85% of total rated current is recommended for two devices in parallel.
