Product details
Overview
PMEG045T100EPDZ from Nexperia is a Trench MEGA Schottky barrier rectifier optimized for low-voltage, high-efficiency power conversion. It delivers 10 A average forward current at 45 V reverse voltage with an ultra-low 480 mV typical forward voltage at 10 A and 25 °C, enabled by clip-bonding thermal enhancement and CFP15B packaging - widely deployed in automotive DC-DC converters and industrial SMPS freewheeling paths.
For engineers reviewing the PMEG045T100EPDZ datasheet, PMEG045T100EPDZ pinout, PMEG045T100EPDZ application, or PMEG045T100EPDZ equivalent, key selection criteria include forward voltage vs. temperature stability, AEC-Q101 qualification status, junction-to-solder-point thermal resistance (3 K/W), and dual-anode cathode-terminal configuration for high-current PCB layout efficiency.
Technical Context
This Schottky rectifier uses trench-based silicon architecture to minimize forward voltage without compromising reverse leakage - achieving 480 mV VF at 10 A/25 °C and only 22 µA IR at 45 V/25 °C. Its clip-bonded construction directly connects die to the cathode thermal pad, enabling 2.15 W power dissipation on a 1 cm² copper pad.
The device operates up to 175 °C junction temperature and supports pulsed forward currents up to 130 A (8 ms). Its step-recovery trr of 40 ns and ramp-recovery trr of 20 ns confirm minimal switching loss in high-frequency (>20 kHz) topologies, validated under AEC-Q101 stress testing for automotive reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 45 V - Maximum blocking capability for 36 V nominal automotive and industrial bus systems. |
| Forward Voltage (VF) | 480 mV typ @ 10 A, 25 °C - Reduces conduction loss by >30% vs. conventional Schottkys in 12–24 V DC-DC stages. |
| Average Forward Current (IF(AV)) | 10 A @ δ = 0.5, f = 20 kHz, Tsp ≤ 142 °C - Sustained output capability in thermally constrained SMD layouts. |
| Thermal Resistance (Rth(j-sp)) | 3 K/W - Enables direct heat transfer from junction to PCB solder point, critical for compact power modules. |
| Reverse Recovery Time (trr) | 20 ns ramp recovery - Minimizes switching loss and EMI in synchronous rectifier and buck converter freewheeling paths. |
| AEC-Q101 Qualified | Yes - Validated for automotive-grade temperature cycling, humidity, and mechanical shock per discrete semiconductor standard. |
| Package | CFP15B (SOT1289B) - Ultra-thin 0.95 mm profile with 5.8 × 4.3 mm footprint and exposed cathode thermal pad. |
Pinout & Package

| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary current entry point; electrically tied to Pin 2 for parallel anode routing and reduced trace inductance. |
| 2 | Anode | Second anode terminal - enables symmetrical high-current input routing and thermal balancing across dual leads. |
| 3 | Cathode | High-current return path and primary thermal interface; large exposed metal pad transfers heat directly to PCB copper. |
Key Features

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 - slightly higher VF and lower VR rating. | Not AEC-Q101 qualified; limited to commercial/industrial use. | Select when VR margin >5 V is acceptable and automotive qualification is not required. |
| ON Semiconductor NSR1040HT1G | 40 V VR, 10 A IF(AV), VF = 500 mV @ 10 A, Rth(j-a) = 100 K/W - no clip bonding, higher thermal resistance. | Lacks thermal pad; unsuitable for high-power-density automotive modules. | Prefer for cost-sensitive non-automotive designs where board-level thermal management is less constrained. |
Compared with VS-10BQ040-M3/45 and NSR1040HT1G, PMEG045T100EPDZ offers superior VR margin (45 V), lowest VF (480 mV), AEC-Q101 compliance, and 3 K/W Rth(j-sp) - making it the only choice for thermally aggressive automotive DC-DC and industrial SMPS requiring long-term reliability at 10 A.

FAQ
Is PMEG045T100EPDZ pin-compatible with earlier CFP15 (SOT1289) packages?
No - PMEG045T100EPDZ uses the updated CFP15B (SOT1289B) package with revised dimensions: 5.8 × 4.3 mm body size and 2.13 mm lead pitch. The earlier CFP15 has different outline tolerances and solder pad requirements; PCB land patterns must be updated to match Figure 14 in the 2019 datasheet.
What is the maximum allowable solder point temperature during reflow?
The absolute maximum solder point temperature is not specified separately, but the device is rated for Tsp ≤ 142 °C under continuous 10 A operation (δ = 0.5). Reflow profiles must comply with IPC/JEDEC J-STD-020, with peak temperature ≤ 260 °C for ≤ 30 seconds - verified per AEC-Q101 reflow testing.
Can PMEG045T100EPDZ replace standard PN-junction rectifiers in 24 V SMPS?
Yes - its 45 V VR rating and 10 A IF(AV) support direct replacement of 30–40 V PN rectifiers in 24 V-output SMPS. However, due to higher reverse leakage (up to 80 µA at 45 V), verify system-level reverse power loss impact - especially in high-temperature or high-VR-bias conditions.
Does the dual-anode configuration require separate PCB traces?
No - Pins 1 and 2 are internally shorted anodes. They may be routed to the same net; using both improves current distribution and reduces localized heating. For optimal thermal performance, connect both anode pads to a common copper pour and ensure the cathode (Pin 3) thermal pad has ≥1 cm² of 2 oz copper.
