Product details
Overview
PMEG045V150EPE-QZ from Nexperia is a 45 V, 15 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) thermal-enhanced ultra-thin SMD package, designed for high-efficiency DC-to-DC conversion and automotive-grade freewheeling paths. It delivers VF = 510–570 mV at 15 A/25 °C, IR ≤ 600 µA at 45 V, and is qualified to AEC-Q101 for under-hood power management.
For engineers reviewing the PMEG045V150EPE-QZ datasheet, PMEG045V150EPE-QZ pinout, PMEG045V150EPE-QZ application, or PMEG045V150EPE-QZ equivalent, key selection criteria include low-VF performance at high current, junction-to-solder-point thermal resistance of 3 K/W, AEC-Q101 qualification, and dual-anode cathode-tab configuration for high-current PCB mounting.
Technical Context
This Schottky rectifier uses planar die construction with clip-bond interconnect technology to minimize parasitic resistance and enable high-power handling in a 5.8 × 4.3 × 0.95 mm flat-lead package. Its dual-anode (pins 1 & 2) and single-cathode (pin 3) topology supports low-inductance, high-current routing directly to thermal pads on FR4 PCBs.
The device exhibits negligible reverse recovery (trr ≤ 36 ns step, ≤ 19 ns ramp), near-zero Qrr, and stable VF across -40 °C to 125 °C operating range - enabling use in synchronous rectification, OR-ing, and reverse polarity protection where fast switching and minimal switching loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 45 V maximum reverse voltage - sets upper limit for blocking capability in 12 V/24 V automotive bus protection and DC-DC input stages. |
| IF(AV) | 15 A average forward current - supports continuous conduction mode operation in high-density buck converters and battery charging circuits. |
| VF @ 15 A | 510–570 mV at 25 °C - enables <1.5 W conduction loss at full load, reducing thermal stress in space-constrained modules. |
| IR @ 45 V | 150–600 µA at 25 °C - ensures low leakage in reverse-biased OR-ing and polarity protection applications. |
| Rth(j-sp) | 3 K/W - thermal path from junction to cathode solder point allows direct heat transfer to large copper areas, enabling >21 A peak current handling. |
| trr (step) | 36 ns - eliminates reverse recovery tail, minimizing EMI and cross-conduction risk in high-frequency (>500 kHz) SMPS designs. |
| AEC-Q101 | Qualified - validated for automotive temperature cycling, humidity, and mechanical shock, supporting under-hood deployment without derating. |
Pinout & Package
Encapsulated in CFP15B (SOT1289B): ultra-thin 5.8 × 4.3 × 0.95 mm surface-mount package with exposed cathode thermal pad and 2.13 mm lead pitch. Optimized for reflow soldering on FR4 with 1 cm² cathode pad per datasheet footprint (Fig. 16).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Anode | Primary anode connection; electrically tied to pin 2; used for parallel high-current input routing. |
| 2 (A) | Anode | Secondary anode; identical to pin 1 - enables dual-path PCB trace layout for reduced current density and inductance. |
| 3 (K) | Cathode | Thermally enhanced tab; sole cathode terminal and primary heat extraction path to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 510–570 mV @ 15 A/25 °C - reduces conduction loss by ≥30% vs. standard Schottkys, improving efficiency in 12 V → 5 V/3.3 V point-of-load converters. |
| Clip-bond construction | Enables 21 A DC forward current rating and 300 A non-repetitive surge - supports robust start-up and fault-current handling in automotive ECUs. |
| CFP15B thermal design | 3 K/W Rth(j-sp) via cathode tab - allows direct thermal coupling to inner-layer copper planes, eliminating need for thermal vias in many layouts. |
| AEC-Q101 qualification | Validated for automotive ambient temperatures (-40 °C to +175 °C) and mechanical reliability - suitable for engine control, ADAS power rails, and body electronics. |
| Step/ramp trr ≤ 36 ns | Eliminates reverse recovery charge (Qrr ≈ 0) - prevents shoot-through in synchronous rectifiers and simplifies gate drive timing in high-side switch configurations. |

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 VR, 15 A IF(AV), VF = 540 mV @ 15 A, TO-252 package, Rth(j-a) = 45 K/W | Larger footprint, higher thermal resistance - requires larger copper area or forced air for same power dissipation. | Prefer when legacy TO-252 layout exists and AEC-Q101 is not required. |
| ON Semiconductor NSR15H45HT1G | 45 V VR, 15 A IF(AV), VF = 520 mV @ 15 A, SOD-123FL package, Rth(j-a) = 120 K/W | Smaller 2-pin package, no thermal tab - limited to ≤5 A continuous in typical layouts due to thermal constraints. | Prefer only for low-power auxiliary rails where board space is critical and thermal budget permits derating. |
Compared with VS-15EWH04-M3 and NSR15H45HT1G, PMEG045V150EPE-QZ offers superior thermal performance (3 K/W vs. ≥45 K/W), AEC-Q101 compliance, and dual-anode layout for lower PCB inductance - making it optimal for high-reliability, high-current automotive power stages.

FAQ
What is the maximum allowable solder point temperature for PMEG045V150EPE-QZ during reflow?
The device is rated for Tsp ≤ 174 °C under δ = 0.5 square-wave conditions per datasheet Table 5. Reflow profile must ensure peak solder point temperature does not exceed 174 °C to maintain 15 A average current capability; recommended reflow peak is 245 °C at component body, with cathode tab reaching ~170 °C under standard 1 cm² pad design.
Can PMEG045V150EPE-QZ be used in synchronous rectification topologies?
No - it is a passive Schottky rectifier, not a controlled switch. However, its 36 ns trr and near-zero Qrr make it suitable as a freewheeling or OR-ing diode in synchronous buck converters where the high-side MOSFET is actively driven and this device handles the low-side conduction path without gate control.
How does the dual-anode configuration affect PCB layout?
Pins 1 and 2 are internally shorted anodes, allowing independent high-current traces from two points on the power net to reduce current density and parasitic inductance. Layout best practice is to route both pins to separate wide copper pours converging at the input node, minimizing loop area for high di/dt switching events.
Is the 45 V reverse voltage rating suitable for 24 V automotive systems with load dump?
Yes - the 45 V VR rating meets ISO 7637-2 Pulse 5a (load dump) requirements when combined with appropriate TVS clamping. With typical clamp voltages ≤ 40 V, the device operates safely within its absolute maximum rating, provided board-level transient suppression is implemented per automotive EMC standards.
