Product details
Overview
PMEG045V150EPDAZ from Nexperia is a 45 V, 15 A low forward-voltage MEGA Schottky barrier rectifier in a CFP15 (SOT1289) thermally enhanced SMD package, featuring integrated guard ring stress protection and clip-bonding for high power capability-used in automotive-grade DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG045V150EPDAZ datasheet, PMEG045V150EPDAZ pinout, PMEG045V150EPDAZ application, or PMEG045V150EPDAZ equivalent, this page delivers verified electrical parameters, thermal performance under FR4 and ceramic PCB mounting, AEC-Q101 qualification status, and real-world design implications of its 430 mV typical VF at 15 A and 270 A IFSM surge rating.
Technical Context
This Schottky rectifier employs planar MEGA technology with an integrated guard ring to suppress edge breakdown and improve reliability under repetitive voltage stress. Its clip-bonded construction directly connects the die to the cathode tab, minimizing thermal resistance and enabling sustained 15 A average forward current at Tsp ≤ 160 °C.
The device exhibits ultra-low forward voltage (430–490 mV at 15 A, 25 °C), negligible reverse recovery (trr < 54 ns step, < 19 ns ramp), and low diode capacitance (610 pF at VR = 10 V), making it suitable for high-frequency switching topologies where conduction loss and switching loss must both be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 15 A | 430–490 mV at 25 °C - enables >95% efficiency in 5–12 V output DC-DC stages with minimal self-heating |
| VR | 45 V maximum reverse voltage - supports 36 V automotive battery systems with 20% margin |
| IF(AV) | 15 A average forward current - rated for continuous operation on FR4 PCB with standard footprint |
| IFSM | 270 A non-repetitive peak forward current - withstands inrush and fault currents in power supply startup |
| Rth(j-sp) | 3 K/W junction-to-solder-point - enables direct thermal coupling to PCB copper pour for high-power density layouts |
| trr (step) | 54 ns - eliminates switching node ringing in synchronous buck freewheeling paths |
| AEC-Q101 | Qualified - validated for automotive under-hood applications including engine control and ADAS power rails |
Pinout & Package
Encapsulated in a CFP15 (SOT1289) thermally enhanced ultra-thin SMD plastic package measuring 5.8 × 4.3 × 0.78 mm, with exposed cathode tab for direct PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary current entry point; dual-anode configuration (Pins 1 & 2) reduces series resistance and current crowding |
| 2 | Anode | Second anode terminal electrically parallel to Pin 1; used for symmetric layout and lower inductance routing |
| 3 | Cathode | Thermally and electrically critical terminal; large copper tab provides low Rth(j-sp) = 3 K/W and serves as main heat path |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge avalanche and improves long-term reliability under repetitive transient overvoltage stress |
| Clip-bonding technology | Reduces thermal resistance by 40% vs. wire-bonded equivalents, enabling higher power density in thin-profile designs |
| 0.78 mm profile height | Enables use in space-constrained automotive modules and portable industrial power supplies |
| Low IR @ 45 V | 260–900 µA reverse leakage - minimizes standby power loss in always-on vehicle subsystems |
| 1870 pF Cd @ 1 V | Supports clean switching in MHz-range DC-DC controllers without added snubbing |

FAQ
What is the maximum allowable solder point temperature for continuous operation?
The datasheet specifies Tsp ≤ 160 °C for IF(AV) = 15 A operation under square-wave conditions (δ = 0.5, f = 20 kHz). Exceeding 160 °C risks derating of average current and accelerated degradation of the clip-bond interface. For DC operation, Tsp must remain ≤ 155 °C per limiting values table.
How does the dual-anode configuration affect PCB layout?
Pins 1 and 2 are internally paralleled anodes, intended for symmetrical routing to minimize loop inductance and current imbalance. Layout best practice requires identical trace length/width from both pins to the input capacitor, with thermal relief minimized to maintain low impedance and uniform current sharing.
Is PMEG045V150EPDAZ suitable for synchronous rectification replacement?
No-it is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier controller or driver. While it can replace older Schottkys in freewheeling roles, it cannot substitute for active gate-driven MOSFETs in synchronous topologies requiring zero-voltage switching control.
What is the significance of the "EPD" suffix in the part number?
The "EPD" denotes Nexperia's Enhanced Power Diode variant: CFP15 package with clip-bonding, guard ring, and AEC-Q101 qualification. It distinguishes this version from earlier SOD123 or SOD128 variants lacking thermal enhancement and automotive qualification.
