Product details
Overview
PMEG4020EP from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency power conversion. It delivers 2 A average forward current at ≤40 V reverse voltage, features 430–490 mV forward voltage at 2 A/25 °C, and uses clip-bond technology in a SOD128 (CFP5) package for enhanced thermal performance in DC-DC converters and SMPS outputs.
For engineers reviewing the PMEG4020EP datasheet, PMEG4020EP pinout, PMEG4020EP application, or PMEG4020EP equivalent, key selection criteria include low VF optimization for efficiency-critical 5–12 V rail rectification, thermal resistance to solder point (12 K/W), and compatibility with reflow/wave soldering on FR4 or ceramic PCBs.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient voltage stress. Its low forward voltage stems from optimized metal-semiconductor interface design, not barrier height reduction alone.
The device operates with zero minority-carrier storage, enabling ultrafast switching (<1 ns recovery) and eliminating reverse recovery charge-critical for high-frequency (>20 kHz) square-wave operation in synchronous rectification and flyback topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 2 A average forward current - supports continuous 2 A load in DC-DC output stage with 140 °C max solder point temperature |
| VR | 40 V peak reverse voltage - suitable for 36 V nominal input rails with 10 % margin against transients |
| VF @ 2 A / 25 °C | 430–490 mV - reduces conduction loss to ≤0.98 W at full load, improving system efficiency by ~1.2 % vs. standard Schottkys |
| IR @ 40 V / 25 °C | 25–100 µA - low leakage preserves battery runtime in always-on low-power circuits |
| Rth(j-sp) | 12 K/W - enables 1.05 W dissipation with only 12.6 °C rise from cathode solder point, critical for compact layouts |
| Cd @ 10 V / 1 MHz | 95 pF - minimizes capacitive switching loss in >1 MHz DC-DC controllers |
Pinout & Package
Encapsulated in a SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4.0 mm lead pitch, flat leads for low-profile mounting and optimal thermal conduction via cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit path; marked with bar; large copper pad required for thermal management and 1.05 W dissipation |
| 2 | Anode (A) | Current entry point; smaller pad area; connects to input rail or switch node in buck/flyback configurations |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge-related avalanche failure, enabling stable 40 V operation without derating at high dv/dt |
| Clip-bond construction | Reduces bond wire inductance and thermal resistance - improves surge current handling (50 A IFSM) and thermal transfer to PCB |
| SOD128 package | Enables 0.5 mm profile height and 2.6 mm width - fits dense power modules where height clearance <1.2 mm is mandatory |
| Reflow/wave solder compatible | Qualified per J-STD-020 and J-STD-006 - eliminates need for special solder profiles or flux types in high-volume manufacturing |
Applications
| Low Voltage Rectification | High-Efficiency DC-DC Conversion |
|---|---|
|
Use Scenario: Output rectification in 3.3 V/5 V buck converters powering FPGAs and microcontrollers. IC Role / Device Role: Unidirectional current path replacing synchronous MOSFETs where gate drive complexity must be avoided. Use Value: 430 mV VF cuts conduction loss by 35 % versus legacy 650 mV Schottkys, directly extending battery life in portable instruments. |
Use Scenario: Secondary-side rectification in isolated 12 V → 5 V flyback supplies for industrial I/O modules. IC Role / Device Role: Freewheeling diode conducting during transformer reset phase. Use Value: 95 pF capacitance limits switching loss at 500 kHz operation, maintaining >92 % efficiency across 10–100 % load range. |
| SMPS Output Stage | Reverse Polarity Protection |
|
Use Scenario: Main output rectifier in 24 V input, 12 V/2 A telecom power supply. IC Role / Device Role: Primary conduction element delivering regulated output with minimal voltage drop. Use Value: 12 K/W Rth(j-sp) allows full 2 A load at 75 °C ambient without heatsink - reducing BOM cost and board area. |
Use Scenario: Input protection in 5 V USB-powered sensor nodes exposed to field wiring errors. IC Role / Device Role: Series-blocking diode preventing damage when power connector is reversed. Use Value: 25 µA max IR at 5 V ensures <13 nW standby power penalty - preserving multi-year battery life in IoT endpoints. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS40201MX | Same 40 V/2 A rating but VF = 480–540 mV @ 2 A; TO-277 package (larger footprint, higher Rth(j-a)) | Less suitable for space-constrained 5 V DC-DC outputs due to 6.5 mm × 3.5 mm body and 180 K/W Rth(j-a) | Select when legacy TO-277 footprint compatibility is required over thermal or height constraints |
| Vishay VSKY240A-M3/84A | 45 V/2 A rating; VF = 450–510 mV @ 2 A; same SOD128 package but no guard ring; IR = 150 µA @ 40 V | Higher leakage increases standby loss in battery-backed systems; lower VR margin for 36 V input rails | Select only if 45 V VR headroom is prioritized over leakage-sensitive operation |
Compared with NSS40201MX and VSKY240A-M3/84A, PMEG4020EP provides the lowest VF (430 mV typ), lowest IR (25 µA max), and integrated guard ring-making it optimal for thermally constrained, high-reliability 5–12 V DC-DC outputs where efficiency and transient robustness are co-prioritized.

FAQ
Is PMEG4020EP suitable for automotive applications?
No. PMEG4020EP is not AEC-Q200 qualified and lacks automotive-grade screening, temperature cycling validation, or guaranteed operation beyond 125 °C junction temperature. It is intended for industrial, computing, and consumer power supplies-not safety-critical vehicle subsystems.
What is the maximum allowable solder point temperature during reflow?
The datasheet specifies Tsp ≤ 140 °C for continuous 2 A operation. Peak reflow temperature must comply with J-STD-020: maximum 260 °C for ≤30 seconds, with ramp rates limited to ≤3 °C/s pre-peak and ≤6 °C/s post-peak to avoid package delamination.
Does PMEG4020EP require a heatsink in 2 A operation?
No heatsink is required if mounted on an FR4 PCB with a 1 cm² cathode copper pad (Rth(j-sp) = 12 K/W). At 2 A and 25 °C ambient, junction temperature rises to ~128 °C - within the 150 °C absolute maximum, provided solder point stays ≤140 °C.
How does the guard ring affect layout requirements?
The guard ring requires ≥0.2 mm clearance between cathode pad edge and adjacent traces or copper pours to prevent field crowding. No additional keep-out is needed beyond standard SOD128 footprint (4.4 mm × 2.1 mm solder land per Fig. 15).
