Product details
Overview
PMEG45T15EPDAZ from Nexperia is a 45 V, 15 A Trench MEGA Schottky barrier rectifier in CFP15 (SOT1289) package, designed for high-efficiency DC-DC conversion and freewheeling paths. It delivers low forward voltage (480–580 mV at 15 A, 25 °C), ultra-low reverse leakage (≤100 µA at 45 V), and thermal resistance as low as 3 K/W junction-to-solder-point - enabling compact, thermally robust power stage designs in space-constrained SMD applications.
For engineers reviewing the PMEG45T15EPDAZ datasheet, PMEG45T15EPDAZ pinout, PMEG45T15EPDAZ application, or PMEG45T15EPDAZ equivalent, key selection criteria include its 45 V reverse rating, 15 A average forward current capability, 60 ns step-recovery time, 2200 pF diode capacitance at 1 V, and clip-bonded thermal performance on FR4 or ceramic PCBs.
Technical Context
This Schottky rectifier uses Trench MEGA technology to suppress leakage current while maintaining low VF - critical for minimizing conduction loss in high-frequency switching topologies. Its dual-anode, single-cathode configuration supports parallel anode routing and optimized current sharing in high-current layouts.
The CFP15 package integrates a thermally enhanced clip-bonded structure with a 0.78 mm profile and exposed cathode tab, enabling direct thermal coupling to PCB copper. Junction-to-solder-point thermal resistance is specified at 3 K/W when soldered to a 1 cm² cathode pad on FR4 - a design-enabling metric for thermal management in 12–48 V industrial and telecom power supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 45 V - defines maximum blocking capability in buck, flyback, or reverse polarity protection circuits. |
| Average Forward Current (IF(AV)) | 15 A - continuous DC current handling at Tsp ≤ 120 °C with 50% duty cycle square wave. |
| Forward Voltage (VF) | 480–580 mV at 15 A, 25 °C - directly reduces conduction loss and improves system efficiency vs. standard Schottkys. |
| Reverse Current (IR) | 30–100 µA at 45 V, 25 °C - low leakage preserves standby power budget in always-on systems. |
| Reverse Recovery Time (trr) | 60 ns (step recovery) - enables operation up to ~5 MHz without significant switching loss penalty. |
| Diode Capacitance (Cd) | 2200 pF at 1 V, 1 MHz - impacts EMI and ringing in high-dV/dt switching nodes; requires layout mitigation. |
| Junction-to-Solder-Point Rth | 3 K/W - enables >1.8 W power dissipation with minimal ΔT on standard FR4 when cathode pad is sized per spec. |
Pinout & Package
Encapsulated in CFP15 (SOT1289): ultra-thin 5.8 × 4.3 × 0.78 mm surface-mount plastic package with thermal-enhanced clip bonding and exposed cathode tab for PCB heat sinking.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Anode | Primary anode connection; electrically identical to Pin 2; intended for parallel routing to reduce trace inductance. |
| 2 (A) | Anode | Secondary anode terminal; shares same internal node as Pin 1 - used for symmetric current distribution in high-current PCB layouts. |
| 3 (K) | Cathode | Exposed metal tab serving as main thermal and electrical return path; must be soldered to ≥1 cm² copper area for rated thermal performance. |
Key Features
| Feature | Design Value |
|---|---|
| Trench MEGA Schottky architecture | Enables simultaneous low VF (480 mV) and low IR (30 µA) - resolving traditional trade-off between conduction loss and leakage. |
| Clip-bonded thermal construction | Reduces Rth(j-sp) to 3 K/W - allows 1.8 W dissipation with only 5.4 °C rise above solder point temperature. |
| Dual-anode, single-cathode topology | Supports symmetrical PCB layout with minimized loop inductance - critical for reducing voltage overshoot in synchronous rectifiers. |
| Ultra-thin 0.78 mm profile | Enables use in height-sensitive applications such as slim AC/DC adapters and stacked power modules. |
Applications
| High-Efficiency DC-DC Converters | Switch-Mode Power Supplies |

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-15EWH04-M3 | 45 V, 15 A; VF = 520–620 mV @ 15 A; Rth(j-a) = 45 K/W (FR4); no dual-anode pinout. | Lacks dual-anode symmetry and clip-bonding - higher thermal resistance limits power density in compact layouts. | Prefer when cost sensitivity outweighs thermal or layout optimization needs. |
| ON Semiconductor NSR15H45HT1G | 45 V, 15 A; VF = 500–600 mV @ 15 A; Rth(j-a) = 50 K/W; TO-277 package (3.5 mm height). | TO-277 footprint increases board height and reduces thermal coupling vs. CFP15's 0.78 mm profile and exposed cathode. | Choose only if existing TO-277 footprint compatibility is mandatory and height is not constrained. |
Compared with VS-15EWH04-M3 and NSR15H45HT1G, PMEG45T15EPDAZ offers superior thermal performance (3 K/W vs. >45 K/W), lower VF at high current, and dual-anode layout flexibility - making it optimal for high-density, high-efficiency 12–48 V power stages where thermal headroom and layout control are critical.

FAQ
What is the maximum junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C. Continuous operation at this limit requires strict thermal design: cathode solder pad ≥1 cm² on FR4, ambient ≤75 °C, and derated current per Figure 1 in the datasheet. At 125 °C junction, VF drops to 405 mV - improving efficiency but demanding tighter thermal control.
Can PMEG45T15EPDAZ replace standard through-hole Schottky diodes in existing designs?
No direct drop-in replacement exists due to its CFP15 (SOT1289) SMD footprint and dual-anode layout. Migration requires PCB redesign to accommodate the 5.8 × 4.3 mm outline, dual-anode routing, and cathode thermal pad. However, its 0.78 mm height and superior thermal metrics often justify the layout update in next-gen compact power designs.
How does the dual-anode configuration affect PCB layout?
Pins 1 and 2 are internally shorted anodes - they must be routed with equal-length, symmetric traces to balance current sharing and minimize parasitic inductance. Unequal routing causes uneven current distribution and localized heating. The recommended layout uses mirrored copper pours connecting both pins to the same net before feeding the power stage.
Is PMEG45T15EPDAZ suitable for automotive applications?
No - this part is not AEC-Q101 qualified and lacks automotive-specific stress testing or qualification documentation. Nexperia explicitly states non-automotive qualification in the datasheet legal section. For automotive use, select Nexperia's AEC-Q101-certified equivalents such as PMEG45T15EPAX or consult official automotive-grade alternatives.
