Product details
Overview
PMEG45A10EPDAZ from Nexperia is a 45 V, 10 A low forward-voltage Schottky barrier rectifier in a thermally enhanced CFP15 (SOT1289) surface-mount package, featuring integrated guard ring stress protection and clip-bonding for high power capability. It delivers VF = 473–540 mV at 10 A and IR ≤ 500 µA at 45 V, enabling high-efficiency low-voltage DC-to-DC conversion in space-constrained power supplies.
For engineers reviewing the PMEG45A10EPDAZ datasheet, PMEG45A10EPDAZ pinout, PMEG45A10EPDAZ application, or PMEG45A10EPDAZ equivalent, key selection criteria include its ultra-low VF, 0.78 mm profile, dual-anode thermal design, and pulsed reverse recovery time of 13 ns under ramp conditions - critical for synchronous rectification and freewheeling in high-frequency SMPS.
Technical Context
This MEGA Schottky rectifier uses planar silicon construction with an integrated guard ring to suppress edge breakdown and improve reliability under transient voltage stress. Its dual-anode (pins 1 & 2) and single-cathode (pin 3) configuration enables symmetric current sharing and optimized thermal path to the PCB via the cathode tab.
The device leverages clip-bonding technology instead of wire bonding, reducing parasitic inductance and enhancing thermal resistance performance: Rth(j-sp) = 4 K/W to solder point and Rth(j-a) = 50 K/W on ceramic PCB. It exhibits negligible reverse recovery (trr = 13 ns ramp, 21 ns step), eliminating switching losses typical of PN junction diodes.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 10 A | 473–540 mV - Enables ≥95% efficiency in 5 V/12 V output stages by minimizing conduction loss |
| VR | 45 V - Rated for 36 V nominal input rails with 25% margin against transients |
| IF(AV) | 10 A - Sustained average current handling with Tsp ≤ 130 °C on standard FR4 |
| trr (ramp) | 13 ns - Supports >1 MHz switching without reverse recovery tail current or ringing |
| Rth(j-sp) | 4 K/W - Direct thermal path from junction to cathode solder point enables high-power density layout |
| Cd @ 10 V | 240 pF - Low junction capacitance minimizes capacitive switching loss and EMI generation |
| IR @ 45 V | 150–500 µA - Low leakage preserves battery life in always-on reverse polarity protection circuits |
Pinout & Package
Encapsulated in the CFP15 (SOT1289) ultra-thin surface-mount package - 5.8 × 4.3 × 0.78 mm body with exposed cathode thermal pad - optimized for high-power density and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary current entry point; electrically and thermally tied to pin 2 for parallel conduction |
| 2 | Anode | Secondary anode terminal; shares internal die connection with pin 1 to double bond-wire current capacity |
| 3 | Cathode | Common cathode terminal with large copper tab - primary thermal and electrical return path to PCB ground plane |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under dv/dt stress, extending lifetime in noisy industrial SMPS |
| Clip-bonded die attach | Reduces thermal resistance by 40% vs. wire-bonded equivalents and eliminates bond-wire fatigue failure |
| Dual-anode configuration | Enables balanced current distribution and lowers effective series resistance in high-current paths |
| 0.78 mm profile | Allows stacking with low-profile inductors and fits under 1 mm height constraints in portable DC/DC modules |
| FR4-compatible footprint | Standard 1 cm² cathode pad achieves 1.2 W dissipation - no special PCB material required for 10 A operation |

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-10BQ040-M3/45 | 40 V VR, 10 A IF(AV), VF = 490 mV @ 10 A, TO-277 package (1.1 mm height) | Larger footprint and 32% higher profile limits use in ultra-thin modules | Select when board-level thermal mass exceeds 2 cm² and lower cost per unit is prioritized over height |
| ON Semiconductor NSR10F40NXT5G | 40 V VR, 10 A IF(AV), VF = 420 mV @ 10 A, SOD-123FL package (1.1 mm height) | Single-anode, 1.7 A/pin rating - requires parallel placement for 10 A, increasing layout area | Select only for low-current auxiliary rails where 10 A total is distributed across ≥2 devices |
Compared with VS-10BQ040-M3/45 and NSR10F40NXT5G, PMEG45A10EPDAZ uniquely combines 45 V rating, dual-anode 10 A capability, and 0.78 mm height - making it the sole option meeting all three requirements in compact, high-efficiency 24–48 V industrial DC/DC designs.

FAQ
What is the maximum continuous junction temperature for PMEG45A10EPDAZ?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating curves in the datasheet show that at 10 A average current, the junction remains within limit only if the solder point temperature stays below 130 °C on standard FR4 PCBs.
Does PMEG45A10EPDAZ require a heatsink for 10 A operation?
No external heatsink is required. With its clip-bonded construction and exposed cathode pad, the device achieves 1.2 W power dissipation on a 1 cm² FR4 copper pad - sufficient for 10 A at 473 mV VF (4.73 W loss) only if ambient temperature is ≤25 °C and airflow is present. For sealed enclosures, thermal simulation using Rth(j-a) = 50 K/W on ceramic PCB is recommended.
Can PMEG45A10EPDAZ be used in automotive applications?
Nexperia explicitly states this part is not automotive-qualified. It lacks AEC-Q101 stress testing and has no guaranteed operation above 125 °C ambient. While functional in non-safety-critical body control modules, it must not be used in ADAS, powertrain, or safety-related systems - and no warranty applies for automotive use per Nexperia's legal disclaimers.
How does the guard ring affect layout or PCB design?
The integrated guard ring eliminates need for external field plates or increased clearance around the device outline. Layout follows standard IPC-7351B CFP15 footprint - no extra keep-out zones or spacing adjustments are required. However, maintaining uninterrupted copper under the cathode tab (≥1 cm²) is essential to realize the specified Rth(j-sp) = 4 K/W thermal performance.
