Product details
Overview
PMEG4020ETP from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for high-temperature operation up to 175 °C, 40 V reverse voltage rating, 2 A average forward current, and low 430–490 mV forward voltage at 2 A/25 °C - deployed in DC-to-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4020ETP datasheet, PMEG4020ETP pinout, PMEG4020ETP application, or PMEG4020ETP equivalent, key selection criteria include thermal performance on FR4 vs. ceramic PCBs, low-VF behavior across temperature (330–380 mV at 2 A/125 °C), reverse leakage stability (≤100 µA at 40 V/25 °C), and SOD128 package compatibility with reflow and wave soldering.
Technical Context
This Schottky diode uses clip-bonding technology to enhance power capability and thermal transfer, enabling sustained 2 A conduction under δ = 0.5 square-wave conditions with Tsp ≤ 165 °C. Its guard ring structure improves robustness against electrical overstress and localized junction degradation.
Thermal resistance varies significantly with board layout: Rth(j-a) is 200 K/W on standard FR4, 120 K/W with 1 cm² cathode pad, and 60 K/W on Al2O3 ceramic - directly impacting maximum ambient operating temperature and derating curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability without breakdown at Tj = 25 °C |
| Average Forward Current (IF(AV)) | 2 A - sustainable DC or pulsed conduction with δ = 0.5, f = 20 kHz, Tsp ≤ 165 °C |
| Forward Voltage (VF) | 430–490 mV at IF = 2 A, Tj = 25 °C - enables <1 W conduction loss in compact power stages |
| Reverse Current (IR) | 25–100 µA at VR = 40 V, Tj = 25 °C - low leakage preserves efficiency in standby and light-load modes |
| Junction Temperature (Tj) | 175 °C - supports operation in high-ambient environments such as automotive under-hood or industrial motor drives |
| Diode Capacitance (Cd) | 95 pF at VR = 10 V, f = 1 MHz - limits switching noise and EMI in high-frequency SMPS designs |
| Non-repetitive Peak Current (IFSM) | 50 A - withstands short-duration inrush or fault currents (tp = 8.3 ms, half-sine) |
Pinout & Package
Encapsulated in a SOD128 (CFP5) surface-mount plastic package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, flat lead profile optimized for automated assembly and thermal dissipation via cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; marked by bar on package; primary thermal path to PCB via large copper area |
| 2 | Anode (A) | Positive input terminal; carries forward current into device; lower thermal contribution than cathode |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves surge robustness and prevents edge breakdown during transient overvoltage events |
| Clip-bonding construction | Reduces bond wire inductance and enhances thermal conductivity from die to cathode tab |
| High-temperature operation | Rated for continuous 175 °C junction temperature - enables use in sealed enclosures or near heat sources |
| Soldering compatibility | Qualified for both reflow and wave soldering per JEDEC standards - supports mixed-technology PCB assembly |
| Low forward voltage drift | VF drops to 330–380 mV at 2 A/125 °C - maintains efficiency across wide thermal range |
Applications
| Low Voltage Rectification | High-Efficiency DC-DC Conversion |
|---|---|
|
Use Scenario: Converting 5 V or 3.3 V rail outputs in point-of-load regulators where minimal voltage drop is critical. IC Role / Device Role / Timing Role: Output rectifier in synchronous or asynchronous buck converter topologies. Use Value: 430–490 mV VF at 2 A reduces conduction loss by ~30% versus standard silicon diodes, improving overall conversion efficiency. |
Use Scenario: Secondary-side rectification in isolated flyback or forward converters powering FPGA or ASIC core rails. IC Role / Device Role / Timing Role: Unidirectional current path with fast recovery (<10 ns) and low stored charge. Use Value: Low Qrr and 95 pF capacitance minimize switching losses and EMI generation at 500 kHz–1 MHz switching frequencies. |
| Reverse Polarity Protection | High-Temperature Industrial Power |
|
Use Scenario: Input protection for battery-powered equipment or USB-C PD adapters exposed to accidental reverse connection. IC Role / Device Role / Timing Role: Series-blocking diode placed between input connector and system power rail. Use Value: Low VF ensures <100 mV dropout at 1 A, preserving usable input voltage range while surviving 50 A surge transients. |
Use Scenario: Power conditioning in motor drive control boards or solar microinverters operating in ambient temperatures up to 110 °C. IC Role / Device Role / Timing Role: Freewheeling or clamp diode handling inductive kickback in high-temp environments. Use Value: 175 °C Tj rating and validated performance on FR4 with 1 cm² cathode pad allow reliable operation without forced cooling. |
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 NSS40201MUTBG | Same SOD128 package, 40 V/2 A rating, but higher typical VF (470–530 mV @ 2 A/25 °C) and wider IR spread (1–200 µA @ 40 V/25 °C) | Less suitable for ultra-low-loss 125 °C+ operation due to higher VF drift and lower thermal margin | Select when cost sensitivity outweighs 40–60 mV VF advantage and tighter leakage control is not required |
| Vishay VS-40CPH03-M3/45 | TO-220AC package, 45 V/40 A rating, higher current capacity but larger footprint and no SMD compatibility | Used in high-power AC/DC front-ends, not space-constrained DC-DC modules | Choose only when >2 A average current or heatsink mounting is mandatory - not a drop-in replacement |
Compared with NSS40201MUTBG and VS-40CPH03-M3/45, PMEG4020ETP delivers superior thermal efficiency in SMD layouts, tighter leakage control, and verified 175 °C operation - making it optimal for miniaturized, high-density, high-temperature power designs where footprint and thermal management are constrained.

FAQ
What is the maximum allowable solder point temperature during reflow for PMEG4020ETP?
The datasheet specifies Tsp ≤ 165 °C for δ = 0.5 square-wave operation, and the device is qualified for standard lead-free reflow profiles with peak temperatures up to 260 °C for ≤30 seconds - provided the solder point (cathode tab) does not exceed 165 °C during steady-state operation post-reflow.
Can PMEG4020ETP be used in automotive under-hood applications?
No - PMEG4020ETP is not AEC-Q200 qualified and lacks automotive-specific qualification testing. While its 175 °C Tj rating supports high-ambient environments, Nexperia explicitly states non-automotive qualification unless otherwise specified, and automotive use requires formal validation beyond datasheet parameters.
How does thermal resistance change with PCB copper area for the cathode pad?
Rth(j-a) improves from 200 K/W (standard FR4 footprint) to 120 K/W with a 1 cm² cathode pad, and further to 60 K/W on Al2O3 ceramic - directly enabling higher IF(AV) at elevated ambient temperatures, as shown in Figures 9–11 of the datasheet.
Is the marking code 'C2' sufficient to identify PMEG4020ETP on the physical device?
Yes - Table 4 confirms 'C2' is the sole marking code for PMEG4020ETP, applied adjacent to the cathode bar on the SOD128 package. This marking is standardized across production lots and verified in the ordering information section (Table 3).
