Product details
Overview
PMEG045T150EPDAZ from Nexperia is a Trench MEGA Schottky barrier rectifier optimized for high-efficiency DC-DC conversion and automotive-grade freewheeling applications, featuring 45 V reverse voltage rating, 15 A average forward current, 480 mV typical forward voltage at 15 A/25 °C, AEC-Q101 qualification, and CFP15 (SOT1289) thermal-enhanced SMD package.
For engineers reviewing the PMEG045T150EPDAZ datasheet, PMEG045T150EPDAZ pinout, PMEG045T150EPDAZ application, or PMEG045T150EPDAZ equivalent, key selection criteria include low VF performance under pulsed 15 A load, thermal resistance to solder point (3 K/W), reverse leakage <100 µA at 45 V/25 °C, and compatibility with FR4 or ceramic PCB mounting configurations.
Technical Context
This Schottky rectifier employs trench-based MEGA architecture to minimize forward voltage drop while maintaining low reverse leakage-critical for synchronous rectification in buck converters and reverse polarity protection circuits. Its clip-bonded construction enables high power capability and direct thermal path from junction to cathode tab.
The device operates with zero minority-carrier storage, delivering 60 ns step-recovery trr and negligible forward recovery voltage (305 mV), making it suitable for high-frequency switching (>20 kHz) where diode switching losses must be minimized. Junction temperature is rated to 175 °C with thermal resistance to ambient as low as 42 K/W on Al₂O₃ ceramic PCB.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 45 V maximum reverse voltage-supports 36 V automotive rail systems with 25 % safety margin. |
| IF(AV) | 15 A average forward current-enables continuous operation in 12–24 V DC-DC stages delivering >180 W output. |
| VF | 480 mV typical at IF = 15 A, 25 °C-reduces conduction loss by ~35 % vs. standard Schottky diodes in same package. |
| IR | 30–100 µA at VR = 45 V, 25 °C-low leakage preserves efficiency in standby and light-load conditions. |
| Rth(j-sp) | 3 K/W thermal resistance to solder point-enables direct heat transfer to PCB copper pour for thermal management. |
| trr | 60 ns step recovery time-eliminates reverse recovery tail, preventing cross-conduction in synchronous FET designs. |
| AEC-Q101 | Qualified for automotive applications-meets stress test requirements for temperature cycling, HTRB, and ESD. |
Pinout & Package
Encapsulated in CFP15 (SOT1289): ultra-thin 5.8 × 4.3 × 0.78 mm surface-mount package with exposed cathode thermal pad and dual anode leads for current sharing and low-inductance layout.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; paralleled with Pin 2 to reduce series resistance and thermal gradient. |
| 2 | Anode | Secondary anode terminal; enables symmetrical PCB routing and balanced current distribution. |
| 3 | Cathode | Thermally enhanced tab-soldered directly to PCB copper pour for optimal heat dissipation (Rth(j-sp) = 3 K/W). |
Key Features
| Feature | Design Value |
|---|---|
| Trench MEGA Schottky technology | Enables 480 mV VF at 15 A while limiting IR to ≤100 µA at 45 V-critical for high-efficiency 12 V/24 V automotive DC-DC stages. |
| Clip-bonded construction | Provides mechanical robustness and low thermal resistance path from die to cathode tab-supports 210 A non-repetitive surge current. |
| CFP15 thermal-enhanced package | 0.78 mm profile allows use in space-constrained modules; 1 cm² cathode pad reduces Rth(j-a) to 70 K/W on FR4. |
| AEC-Q101 qualification | Validated for automotive under-hood environments including temperature cycling (−40 °C to 150 °C) and humidity testing. |
| Step-recovery trr | 60 ns recovery time eliminates reverse recovery charge-prevents shoot-through in synchronous buck controllers operating >500 kHz. |
Applications
| Automotive DC-DC Converters | Industrial SMPS Output Rectification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS1545CGY | 45 V VR, 15 A IF(AV), VF = 520 mV @ 15 A, TO-277 package (3.1 mm height), no AEC-Q101 qualification. | Higher VF increases conduction loss by ~8 %; taller package limits use in ultra-thin modules; not automotive-qualified. | Select when AEC-Q101 is not required and board height >3 mm permits TO-277 footprint. |
| ONsemi NSR1545HT1G | 45 V VR, 15 A IF(AV), VF = 490 mV @ 15 A, SOD-123FL package (1.7 mm height), AEC-Q101 qualified. | Lower current density due to smaller die; Rth(j-a) = 100 K/W limits power handling to ≤5 A continuous on FR4. | Select for space-constrained consumer applications where peak current ≤8 A and thermal budget allows higher Rth. |
Compared with STPS1545CGY and NSR1545HT1G, PMEG045T150EPDAZ delivers lowest VF in its class, best thermal performance via clip-bonded CFP15, and full AEC-Q101 validation-making it the preferred choice for automotive and high-power-density industrial DC-DC designs.

FAQ
What is the maximum allowable junction temperature for PMEG045T150EPDAZ?
The absolute maximum junction temperature is 175 °C, validated per IEC 60134 limiting values. Operation at this temperature requires strict thermal design: Rth(j-sp) = 3 K/W demands direct soldering of the cathode tab to ≥1 cm² copper pour on FR4 or ceramic PCB. Derating curves in Figures 9–12 define safe IF(AV) limits based on ambient or solder point temperature.
Does PMEG045T150EPDAZ have a specified reverse recovery charge (Qrr)?
No-this is a Schottky barrier rectifier with majority-carrier conduction; it exhibits no reverse recovery charge. The datasheet specifies trr = 60 ns (step recovery) and trr = 20 ns (ramp recovery), but these reflect measurement methodology-not stored charge. Qrr is inherently zero, eliminating switching losses associated with minority-carrier diodes.
Can PMEG045T150EPDAZ be used in parallel configurations?
Yes-dual anode terminals (Pins 1 and 2) are internally bonded to the same die region and electrically identical, enabling low-inductance parallel routing. For multi-device paralleling, ensure matched PCB trace lengths and thermal coupling to avoid current imbalance; derate total IF(AV) by 15 % for two devices.
Is the marking code "045T 150E" sufficient to identify PMEG045T150EPDAZ on the device body?
Yes-the top-side marking "045T 150E" corresponds exclusively to PMEG045T150EPD per Table 4 of the datasheet. "045T" denotes 45 V VR and Trench technology; "150E" indicates 15 A IF(AV) and CFP15 package. No other Nexperia part shares this exact marking combination.
