Product details
Overview
PMEG45U10EPDAZ from Nexperia is a 45 V, 10 A extremely low forward-voltage Schottky barrier rectifier in a thermally enhanced CFP15 (SOT1289) surface-mount package, featuring dual-anode / single-cathode configuration, integrated guard ring for stress protection, and clip-bonding technology enabling high power capability with typical height of 0.78 mm - used in high-efficiency DC-DC converters and freewheeling paths in synchronous buck regulators.
For engineers reviewing the PMEG45U10EPDAZ datasheet, PMEG45U10EPDAZ pinout, PMEG45U10EPDAZ application, or PMEG45U10EPDAZ equivalent, key selection criteria include forward voltage at 10 A (430–490 mV), reverse leakage at 45 V (230–600 µA), thermal resistance to solder point (3 K/W), and SOT1289 package compatibility with high-density PCB layouts requiring low-profile thermal management.
Technical Context
This MEGA Schottky rectifier uses planar silicon construction with an integrated guard ring to suppress edge breakdown under high dv/dt or mechanical stress. Its dual-anode layout (Pins 1 & 2) shares cathode current path (Pin 3), enabling symmetrical current distribution and reduced parasitic inductance in high-frequency switching nodes.
The device leverages clip-bonding instead of wire bonding to lower thermal resistance and improve surge current handling (180 A non-repetitive peak). Its ultra-thin 0.78 mm profile and ceramic-compatible footprint support thermal performance on Al₂O₃ substrates (Rth(j-a) = 40 K/W) or FR4 with extended cathode pad (Rth(j-sp) = 3 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 10 A | 430–490 mV - enables ≥95% efficiency in 5 V/12 V output DC-DC stages by minimizing conduction loss |
| VR | 45 V - supports input rails up to 36 V nominal with 20% margin for transient overshoot |
| IF(AV) | 10 A - rated for continuous operation at 130 °C solder point temperature with 50% duty cycle square wave |
| IR @ 45 V | 230–600 µA @ 25 °C - low leakage preserves efficiency in standby and light-load conditions |
| trr (ramp) | 16 ns - eliminates reverse recovery tail, reducing EMI and gate drive losses in synchronous FETs |
| Rth(j-sp) | 3 K/W - direct thermal path from junction to cathode solder point enables >3 W dissipation on optimized PCB |
| Cd @ 10 V | 390 pF - low capacitance minimizes switching loss and ringing in MHz-range converters |
Pinout & Package
Encapsulated in SOT1289 (CFP15): ultra-thin surface-mount plastic package measuring 5.8 × 4.3 × 0.78 mm, with exposed cathode thermal pad and flat leads for low-inductance, high-current routing.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; electrically identical to Pin 2; used for parallel current entry in high-current paths |
| 2 | Anode | Secondary anode connection; symmetric to Pin 1; enables balanced current sharing and reduced trace inductance |
| 3 | Cathode | Common cathode terminal with large copper tab; serves as primary thermal and current return path to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Extremely low VF | 430 mV typ. @ 10 A - reduces conduction loss by >40% vs. standard Schottkys, critical for 5–12 V POL converters |
| Integrated guard ring | Edge termination structure - prevents premature avalanche at junction periphery under high dv/dt or mechanical stress |
| Clip-bonding technology | Eliminates bond wires - lowers RDS(on)-equivalent resistance and improves IFSM to 180 A (8 ms) |
| Ultra-thin SMD profile | 0.78 mm max height - enables use in space-constrained applications including portable power modules and stacked PCBs |
| Thermal-enhanced cathode pad | Direct thermal interface to PCB - achieves 3 K/W Rth(j-sp), supporting >3 W continuous dissipation |

IC Role / Device Role / Timing Role: Output rectifier in compact 2-layer PCB-mounted buck converter; operates continuously at Tsp ≤ 130 °C. Use Value: CFP15 package's 0.78 mm height allows integration beneath connectors and shields, meeting strict Z-axis stacking constraints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSKY10040M | 40 V VR, 10 A IF(AV), VF = 470 mV @ 10 A, TO-277 package (3.5 mm height) | Larger footprint and higher profile limits use in ultra-thin designs; higher Rth(j-a) (15 K/W) | Select when board-level thermal mass compensates for higher VF and package height is not constrained. |
| ON Semiconductor SBRA1045 | 45 V VR, 10 A IF(AV), VF = 480 mV @ 10 A, SOD-123FL package (1.1 mm height) | Single-anode, lower surge rating (120 A IFSM), no guard ring; unsuitable for high-dv/dt freewheeling | Choose only for low-stress, low-frequency rectification where cost outweighs reliability and efficiency requirements. |
Compared with VSKY10040M and SBRA1045, PMEG45U10EPDAZ delivers superior thermal performance (3 K/W Rth(j-sp)), lowest VF in class, and robust guard-ring protection - making it optimal for high-density, high-efficiency, and high-reliability DC-DC applications where board space and thermal headroom are limited.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C, but continuous operation is specified up to Tsp ≤ 130 °C (solder point) under square-wave conditions with 50% duty cycle at 20 kHz. Derating is required above this temperature; thermal design must ensure Rth(j-sp) × Pdiss + Tsp ≤ 150 °C.
Can PMEG45U10EPDAZ be used in place of a standard through-hole Schottky in existing designs?
No - its SOT1289 (CFP15) package is surface-mount only, with a 5.8 × 4.3 mm footprint and 0.78 mm height incompatible with through-hole pads or axial leads. Retrofit requires PCB redesign, stencil adjustment, and reflow profile validation due to its thermal pad and dual-anode layout.
Does the dual-anode configuration require separate PCB traces for Pins 1 and 2?
No - Pins 1 and 2 are internally shorted anodes and may be connected to the same net. However, routing them separately to split high-current paths reduces localized heating and trace inductance; best practice is symmetric copper pours from both pins to a common node before reaching the cathode.
Is PMEG45U10EPDAZ qualified for automotive applications?
No - this part is not AEC-Q101 qualified and lacks automotive-specific testing or qualification documentation. It is intended for industrial, computing, and consumer power applications. For automotive use, Nexperia offers the AEC-Q101-qualified PMEG45U10EPDAX variant with identical electrical specs and enhanced reliability screening.
