Product details
Overview
PMEG040V030EPE-QZ from Nexperia is a 40 V, 3 A planar low forward voltage Schottky barrier rectifier in a CFP15B (SOT1289B) thermally enhanced SMD package, designed for high-efficiency DC-to-DC conversion and freewheeling in automotive power systems. It delivers VF = 425 mV (typ.) at IF = 3 A and Tj = 25 °C, supports 120 A non-repetitive peak forward current, and is qualified to AEC-Q101.
For engineers reviewing the PMEG040V030EPE-QZ datasheet, PMEG040V030EPE-QZ pinout, PMEG040V030EPE-QZ application, or PMEG040V030EPE-QZ equivalent, key selection criteria include ultra-low VF for minimal conduction loss, clip-bond thermal performance enabling 3 A continuous operation on FR4, and AEC-Q101 qualification for under-hood automotive use.
Technical Context
This Schottky rectifier uses planar die construction with copper clip-bond interconnection to minimize parasitic resistance and thermal impedance. Its dual-anode configuration (Pins 1 & 2) and single cathode (Pin 3) support high-current routing while maintaining low Rth(j-sp) = 3 K/W to the cathode solder point.
The device exhibits negligible reverse recovery (trr ≤ 12 ns step, ≤ 11 ns ramp) and low diode capacitance (Cd = 370 pF at VR = 1 V), making it suitable for high-frequency switching topologies up to 20 kHz with minimal switching loss and EMI generation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR | 40 V maximum reverse voltage - sets safe operating limit in 24 V automotive systems with load-dump transients. |
| IF(AV) | 3 A average forward current - sustained DC or square-wave operation at δ = 0.5, f = 20 kHz, with Tsp ≤ 173 °C on standard FR4. |
| VF | 425 mV typical at IF = 3 A, Tj = 25 °C - reduces conduction loss by >30% vs. standard Schottkys, improving system efficiency. |
| IR | 30 µA typical at VR = 40 V, Tj = 25 °C - ensures low leakage in reverse-biased OR-ing and polarity protection circuits. |
| Rth(j-sp) | 3 K/W - thermal resistance from junction to cathode solder point, enabling high-power dissipation with minimal board area. |
| trr | 11 ns ramp recovery - eliminates reverse recovery tail, minimizing switching losses in synchronous rectifier and flyback designs. |
| Q101 Qualification | AEC-Q101 qualified - validated for automotive temperature range (−40 °C to +175 °C junction), including HTOL, TC, and HTRB stress tests. |
Pinout & Package
Encapsulated in a CFP15B (SOT1289B) thermally enhanced ultra-thin SMD package: 5.8 × 4.3 × 0.95 mm body, 2.13 mm lead pitch, with exposed cathode tab for low-impedance thermal path.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; electrically tied to Pin 2; used for high-current input routing in parallel-anode layout. |
| 2 | Anode | Secondary anode connection; identical to Pin 1; enables symmetrical PCB trace layout and current sharing. |
| 3 | Cathode | Common cathode terminal with large metal tab - serves as primary thermal and electrical return path; must be soldered to ≥1 cm² copper pad. |
Key Features
| Feature | Design Value |
|---|---|
| Very low VF | 425 mV typ. @ 3 A - directly reduces I²R conduction loss in 12/24 V DC-DC stages, increasing efficiency by up to 1.2% at full load. |
| Clip-bond technology | Enables 4.2 A DC forward current rating and 120 A IFSM - supports high-pulse surge handling in motor drive freewheeling and battery protection. |
| AEC-Q101 qualification | Validated for automotive under-hood environments - guarantees reliability over 15-year vehicle lifetime with no derating required at Tj ≤ 175 °C. |
| CFP15B package | 0.95 mm profile with thermal-enhanced cathode tab - allows placement in space-constrained modules (e.g., ADAS ECUs, LED drivers) without compromising thermal performance. |
Applications
| High-Efficiency DC-DC Conversion | Reverse Polarity Protection |

Use Scenario: Secondary-side synchronous rectification in 24 V → 5 V/3.3 V buck converters for automotive infotainment and ADAS modules. IC Role / Device Role / Timing Role: Low-VF Schottky rectifier replacing MOSFETs in self-driven configurations; operates during low-side switch conduction phase. Use Value: 425 mV VF cuts conduction loss by 45% vs. 780 mV alternatives, reducing thermal load on compact PCBs and enabling higher power density. |
Use Scenario: Input protection circuit for 12 V/24 V telematics control units exposed to battery reversal during service. IC Role / Device Role / Timing Role: Series-connected anode-to-input, cathode-to-system rail; blocks reverse current while passing forward current with minimal drop. Use Value: 425 mV forward drop preserves >98% of supply voltage at 3 A, avoiding brownout in critical microcontroller domains during normal operation. |
| Freewheeling Diode | OR-ing Circuit |
|
Use Scenario: Freewheel path in brushed DC motor drivers for power seats and HVAC actuators. IC Role / Device Role / Timing Role: Provides low-loss current recirculation path when H-bridge low-side switches turn off; handles 120 A IFSM surges. Use Value: 11 ns trr prevents voltage spikes exceeding 40 V rating during fast current decay, eliminating need for snubbers in cost-sensitive designs. |
Use Scenario: Dual-supply redundancy in gateway ECUs where main and backup 12 V rails feed common 5 V domain. IC Role / Device Role / Timing Role: Anode connected to each input rail, shared cathode to output; conducts only from higher-voltage source. Use Value: 30 µA IR at 40 V reverse bias ensures <1 mW standby loss per diode, extending sleep-mode battery life in always-on vehicle networks. |
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-3EYH04-M3/54 | 45 V VR, 3 A IF(AV), VF = 490 mV @ 3 A, TO-277 package (3.5 mm height) | Larger footprint and 0.6 mm taller - limits use in ultra-thin modules; lacks AEC-Q101 certification | Select when VR margin >5 V is required and board height >1.5 mm is acceptable; not recommended for new automotive designs. |
| ON Semiconductor NSR340SDT5G | 40 V VR, 3 A IF(AV), VF = 450 mV @ 3 A, SOD-123FL package (1.7 mm height) | Higher Rth(j-a) = 120 K/W - limits continuous current to 1.2 A on FR4; no clip-bond thermal enhancement | Use only in low-power, space-constrained consumer applications; insufficient thermal capability for automotive 3 A loads. |
Compared with VS-3EYH04-M3/54 and NSR340SDT5G, PMEG040V030EPE-QZ uniquely combines AEC-Q101 qualification, 3 K/W Rth(j-sp), and 425 mV VF in a 0.95 mm profile - enabling reliable 3 A operation in automotive-grade, height-sensitive power stages where thermal and qualification constraints dominate.

FAQ
What is the maximum continuous forward current for PMEG040V030EPE-QZ on a standard FR4 PCB?
The device supports 3 A average forward current (IF(AV)) under square-wave conditions (δ = 0.5, f = 20 kHz) with solder point temperature ≤173 °C on a single-sided tin-plated FR4 board using the standard footprint. Derating applies above 85 °C ambient.
Does PMEG040V030EPE-QZ require a heatsink for 3 A operation?
No external heatsink is required. The CFP15B package's clip-bond construction and exposed cathode tab achieve Rth(j-sp) = 3 K/W when soldered to a 1 cm² copper pad, allowing full 3 A operation with Tj ≤ 175 °C on standard FR4 without additional thermal hardware.
How does the dual-anode pinning improve PCB layout?
Pins 1 and 2 are internally shorted anodes, enabling symmetric high-current trace routing from both sides of the package. This reduces current crowding, lowers loop inductance in switching paths, and improves thermal distribution across the anode metallization - critical for EMI-sensitive automotive converters.
Is PMEG040V030EPE-QZ compatible with lead-free reflow profiles?
Yes. The CFP15B package is qualified for standard IPC/JEDEC J-STD-020D-compliant lead-free reflow, with peak temperature up to 260 °C. The recommended stencil thickness is 0.125 mm, and the footprint matches Figure 16 in the official datasheet for optimal solder paste volume control.
