Product details
Overview
PMEG045T100EPE from Nexperia is a 45 V, 10 A trench Schottky barrier rectifier in a CFP15B (SOT1289B) ultra-thin SMD package, designed for low-voltage, high-efficiency DC-to-DC conversion and freewheeling paths in power supplies. It delivers 480 mV typical forward voltage at 10 A/25 °C, 22 µA max reverse leakage at 45 V/25 °C, and features clip-bonding for enhanced thermal performance in space-constrained applications.
For engineers reviewing the PMEG045T100EPE datasheet, PMEG045T100EPE pinout, PMEG045T100EPE application, or PMEG045T100EPE equivalent, key selection criteria include its ultra-low VF, 0.95 mm profile, 3 K/W junction-to-solder-point thermal resistance, and dual-anode configuration enabling high-current routing with minimal PCB footprint.
Technical Context
This device uses trench Schottky architecture to minimize forward voltage drop while maintaining stable reverse leakage across -40 °C to 125 °C operating junction temperatures. Its dual-anode (pins 1 & 2) and single-cathode (pin 3) terminal arrangement supports parallel current handling without external bus bars.
The CFP15B package integrates a thermally enhanced cathode tab directly bonded to the die, achieving 3 K/W Rth(j-sp) when mounted on a 1 cm² copper pad - critical for sustaining 10 A average forward current at Tsp ≤ 142 °C in compact SMPS designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 10 A | 480–545 mV at 25 °C: enables >95% efficiency in 5 V/12 V buck converters with minimal conduction loss. |
| VR | 45 V maximum: suitable for 36 V nominal input rails with 20% margin, including automotive 24 V systems. |
| IF(AV) | 10 A continuous: supports high-density power stages without forced air cooling on standard FR4 PCBs. |
| IR @ 45 V | 22–80 µA at 25 °C: ensures negligible standby power loss in battery-powered reverse polarity protection circuits. |
| Rth(j-sp) | 3 K/W: allows direct thermal coupling to PCB ground plane, reducing need for heatsinks in <10 W modules. |
| trr | 20 ns ramp recovery: minimizes switching loss and EMI in 500 kHz–1 MHz synchronous rectifier replacements. |
| Package | CFP15B (SOT1289B): 5.8 × 4.3 × 0.95 mm body with 2.13 mm lead pitch - fits tight-layout USB-C PD and PoE injectors. |
Pinout & Package
Encapsulated in a thermally optimized CFP15B (SOT1289B) surface-mount plastic package with exposed cathode thermal pad, 0.95 mm profile, and 2.13 mm lead pitch. The package uses clip-bonding technology to maximize heat transfer from die to solder point.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A) | Anode | Primary anode connection; electrically identical to Pin 2 - enables dual-path current injection for reduced trace resistance. |
| 2 (A) | Anode | Secondary anode; used in parallel with Pin 1 to distribute 10 A forward current across two PCB traces or planes. |
| 3 (K) | Cathode | Thermally enhanced cathode tab; must be soldered to ≥1 cm² copper area to achieve rated 10 A IF(AV) and 3 K/W Rth(j-sp). |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low VF trench Schottky | 480 mV typ. @ 10 A/25 °C - reduces conduction loss by ≥30% vs. planar Schottky alternatives in 5–12 V output rails. |
| Clip-bonded thermal construction | 3 K/W Rth(j-sp) - enables full 10 A rating with only PCB copper as heatsink, eliminating discrete thermal interface materials. |
| Dual-anode configuration | Pins 1 & 2 both anodes - simplifies high-current layout by splitting return path across two vias/traces, lowering IR drop and thermal hotspot risk. |
| 0.95 mm profile | Height compliant with ultra-thin portable electronics (e.g., slim AC adapters, wearable chargers) where Z-height is constrained to <1.0 mm. |
| 175 °C max junction temperature | Supports operation in sealed enclosures or high-ambient environments (e.g., industrial gateways) without derating below 10 A up to 85 °C ambient. |
Applications
| USB-C Power Delivery Adapter | Industrial 24 V DC-DC Converter |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in 65 W USB-C PD adapter with 20 V output. IC Role / Device Role / Timing Role: Low-VF freewheeling diode replacing MOSFET gate driver complexity in cost-sensitive designs. Use Value: 480 mV VF cuts conduction loss by 0.48 W vs. 1 V Si diode, improving full-load efficiency from 92% to 93.5% without changing transformer turns ratio. |
Use Scenario: Input rectification for isolated 24 V → 5 V/3 A flyback converter in PLC I/O module. IC Role / Device Role / Timing Role: Input bridge leg in low-noise industrial supply where reverse leakage must stay <100 µA at 45 V bias. Use Value: 22 µA max IR at 45 V/25 °C prevents >1 µW standby drain - critical for always-on fieldbus nodes with battery backup. |
| Reverse Polarity Protection Circuit | Automotive Body Control Module (Non-AEC-Q) |
|
Use Scenario: Series protection diode on 12 V battery input of smart sensor node. IC Role / Device Role / Timing Role: Unidirectional current valve blocking reverse connection during installation or maintenance. Use Value: Dual-anode layout allows 10 A fault current handling with <0.5 mΩ effective series resistance, limiting voltage drop to <5 mV at 10 A. |
Use Scenario: 12 V auxiliary rail rectification in non-safety-critical BCM subassembly (e.g., mirror heater control). IC Role / Device Role / Timing Role: High-reliability rectifier for 12 V input filtering where thermal cycling exceeds 1000 cycles. Use Value: Clip-bonded construction withstands 175 °C Tj and 130 A IFSM surge, surviving load-dump transients without bond wire lift-off. |
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-10SQ045ST | Same 45 V/10 A rating but TO-277 package (4.5 mm height); VF = 520 mV min @ 10 A; no dual-anode terminals. | Requires larger PCB area and vertical clearance; less suitable for ultra-thin adapters. | Select when board height >1.5 mm is acceptable and thermal pad soldering is not feasible. |
| ON Semiconductor NSR1045HT1G | SOD-123FL package (1.7 mm height); VF = 550 mV typ @ 10 A; IF(AV) derated to 6.5 A at 100 °C ambient. | Limited to lower-power applications (<30 W); higher thermal resistance limits sustained 10 A operation. | Choose for cost-sensitive, low-density layouts where 0.95 mm Z-height is not mandatory. |
Compared with VS-10SQ045ST and NSR1045HT1G, PMEG045T100EPE uniquely combines 0.95 mm profile, dual-anode routing, and 3 K/W thermal resistance - making it the only option capable of delivering full 10 A in <1 mm height with PCB-only thermal management.

FAQ
What is the maximum allowable solder point temperature for continuous 10 A operation?
The datasheet specifies Tsp ≤ 142 °C for δ = 0.5 duty cycle at 20 kHz to sustain 10 A average forward current. This requires a minimum 1 cm² cathode copper pad on FR4 with tin plating. Exceeding 142 °C risks irreversible degradation of the clip-bond interface and accelerated IR drift.
Can Pins 1 and 2 be used independently in separate circuit branches?
No - Pins 1 and 2 are internally shorted anodes and share the same silicon die. Using them in separate branches creates unintended current sharing imbalance and violates the thermal model. They must be routed to the same net to maintain specified VF and thermal performance.
Is this device suitable for automotive applications requiring AEC-Q200 qualification?
No - PMEG045T100EPE is not AEC-Q200 qualified. Nexperia explicitly states in the legal disclaimers that non-automotive qualified products are unsuitable for safety-critical automotive use. For AEC-Q200-compliant alternatives, consult Nexperia's Automotive Schottky portfolio (e.g., PMEG045T100EPAX).
How does the 20 ns trr value impact EMI in high-frequency SMPS designs?
A 20 ns ramp recovery time minimizes reverse recovery charge (Qrr) and associated dI/dt-induced ringing, reducing high-frequency EMI peaks above 30 MHz. This allows simpler input filter design in 1 MHz buck converters, cutting common-mode choke size by ~30% compared to 50 ns trr devices.
