Product details
Overview
PMEG040V050EPDZ from Nexperia is a 40 V, 5 A low forward-voltage Schottky barrier rectifier in a CFP15 (SOT1289) surface-mount package, featuring integrated guard ring stress protection and clip-bonding for enhanced thermal performance. It serves as a high-efficiency freewheeling or reverse polarity protection diode in automotive DC-DC converters and industrial power supplies.
For engineers reviewing the PMEG040V050EPDZ datasheet, PMEG040V050EPDZ pinout, PMEG040V050EPDZ application, or PMEG040V050EPDZ equivalent, key selection criteria include its 475 mV typical VF at 5 A/25 °C, AEC-Q101 qualification, 3 K/W Rth(j-sp), dual-anode cathode-terminal configuration, and ultra-thin 0.78 mm profile for space-constrained PCB layouts.
Technical Context
This MEGA Schottky rectifier uses planar silicon technology with an integrated guard ring to suppress edge breakdown under high dv/dt or mechanical stress. Its clip-bonded construction directly connects the die to the cathode thermal pad, enabling 2.15 W total power dissipation on a 1 cm² copper pad.
The device exhibits negligible reverse recovery (trr ≤ 13 ns step, ≤ 11 ns ramp), making it suitable for high-frequency switching topologies. Its low capacitance (130 pF at VR = 10 V) and temperature-stable VF (415 mV at 5 A/125 °C) support stable operation across automotive ambient ranges (−40 °C to +175 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 5 A, 25 °C | 475 mV typical - enables <1.2 W conduction loss at full load in 12 V systems |
| VR (max) | 40 V - supports 24 V nominal automotive and industrial bus rails with margin |
| IF(AV) (max) | 5 A - rated for continuous square-wave operation at Tsp ≤ 158 °C |
| Rth(j-sp) | 3 K/W - enables efficient heat transfer from junction to solder point via cathode tab |
| trr (step) | 13 ns - eliminates switching losses in >500 kHz SMPS freewheeling paths |
| AEC-Q101 | Qualified - certified for automotive-grade reliability per stress test standard |

Pinout & Package
Encapsulated in a thermally enhanced CFP15 (SOT1289) plastic SMD package with 3 terminals: two anodes (pins 1 and 2) and one cathode (pin 3). The exposed cathode pad provides primary thermal path to PCB.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary current entry point; electrically tied to pin 2; requires symmetric layout for balanced current sharing |
| 2 | Anode | Secondary anode terminal; parallel-connected to pin 1 for 5 A total average current handling |
| 3 | Cathode | Common output terminal and thermal interface; soldered to large copper area for Rth(j-sp) = 3 K/W |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under high dv/dt or mechanical stress in automotive environments |
| Clip-bonding technology | Reduces thermal resistance by direct die-to-cathode metal connection, enabling 2.15 W dissipation |
| Ultra-low VF | 475 mV typ. at 5 A/25 °C - cuts conduction loss by ~35% vs. standard Schottkys in 12 V–24 V systems |
| Thin profile (0.78 mm) | Enables use in height-sensitive applications such as slim automotive ECUs and portable industrial controllers |
| AEC-Q101 qualification | Validated for automotive under-hood and battery-management applications requiring extended temperature and lifetime reliability |
Applications
| Automotive DC-DC Converters | Industrial Power Supplies |
|---|---|
|
Use Scenario: Step-down conversion from 48 V or 24 V battery rail to 5 V/3.3 V logic rails in ADAS ECUs. IC Role / Device Role / Timing Role: Freewheeling diode in synchronous buck converter secondary side, operating at 300–600 kHz. Use Value: 475 mV VF minimizes conduction loss; 13 ns trr prevents shoot-through and EMI during high-frequency switching. |
Use Scenario: Output rectification in isolated flyback or forward converters for factory automation I/O modules. IC Role / Device Role / Timing Role: Low-loss output rectifier replacing conventional PN diodes to improve efficiency above 85%. Use Value: 2.15 W power rating with 1 cm² copper pad allows compact heatsinkless design in sealed enclosures. |
| Reverse Polarity Protection | Low-Power Consumption Devices |
|
Use Scenario: Input protection for 12 V vehicle infotainment head units against accidental battery reversal. IC Role / Device Role / Timing Role: Series-blocking Schottky in high-side configuration, conducting only during correct polarity. Use Value: 32 µA max IR at 40 V/25 °C ensures <0.4 mW standby leakage-critical for always-on subsystems. |
Use Scenario: Power-path management in battery-powered IoT sensors with strict quiescent current budgets. IC Role / Device Role / Timing Role: Reverse-current blocker between Li-ion cell and system load during sleep mode. Use Value: 6 µA typ. IR at 10 V enables sub-1 µA system-level leakage when combined with low-IQ regulators. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| STPS5L40SF | Same 40 V/5 A rating but TO-277 package (3.1 × 3.1 × 0.9 mm); VF = 490 mV typ. at 5 A | Larger footprint and higher Rth(j-a); less suitable for ultra-thin automotive modules | Preferred where legacy TO-277 footprint compatibility is required over thermal or height optimization |
| RB055LAM-40 | 40 V/5 A, CFP15-equivalent package but no AEC-Q101 qualification; VF = 480 mV typ. at 5 A | Not qualified for automotive use; limited to commercial/industrial temperature range (−40 °C to +125 °C) | Cost-optimized alternative for non-automotive applications where AEC-Q101 is not mandated |
Compared with STPS5L40SF and RB055LAM-40, PMEG040V050EPDZ delivers superior thermal performance (Rth(j-sp) = 3 K/W), AEC-Q101 compliance, and lowest VF in its class-making it optimal for space-, thermal-, and reliability-constrained automotive power designs.

FAQ
What is the maximum junction temperature and how does it affect derating?
The absolute maximum junction temperature is 175 °C. Derating begins at Tj > 125 °C: IF(AV) drops linearly from 5 A at 158 °C solder point temperature to zero at 175 °C. Thermal design must maintain Tsp ≤ 158 °C using ≥1 cm² cathode copper for full 5 A rating.
Is the dual-anode configuration internally paralleled or separate dies?
PMEG040V050EPDZ uses a single silicon die with two bonded anode leads (pins 1 and 2) to distribute current and reduce package inductance. Both anodes are electrically common and must be routed with matched impedance to ensure balanced current sharing.
How does the guard ring impact layout requirements?
The integrated guard ring enhances edge breakdown immunity but requires strict adherence to the recommended CFP15 footprint (SOT1289) with 1.7 mm cathode land width and 2.13 mm anode land spacing. Deviations increase risk of localized field concentration and premature failure under surge conditions.
Can this diode replace a standard PN rectifier in existing 24 V designs?
Yes-its 40 V VR rating and 5 A IF(AV) match common 24 V system requirements. Replacing a PN diode reduces conduction loss by ~60% (e.g., from 1.1 V to 0.475 V), lowering thermal stress and improving efficiency by 2–3% in typical buck converters without circuit modification.
