Product details
Overview
PMEG3020EGWJ from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 2 A average forward current, featuring low 510 mV typical forward voltage and 400 µA typical reverse leakage - deployed in low-voltage DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3020EGWJ datasheet, PMEG3020EGWJ pinout, PMEG3020EGWJ application, or PMEG3020EGWJ equivalent, this page delivers verified electrical parameters, SOD123 package layout, thermal resistance values, and application-specific design guidance for high-efficiency power management.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against transient overvoltage and electrostatic stress. Its low VF enables reduced conduction loss in compact power supplies operating below 30 V.
Thermal performance is defined by Rth(j-a) = 310 K/W (free air) and Rth(j-sp) = 190 K/W (with 1 cm² cathode pad), supporting reliable operation up to 150 °C junction temperature under pulsed or continuous DC conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 30 V - maximum blocking capability for 24 V rail protection and buck converter freewheeling |
| Avg Forward Current | 2 A - sustained DC output rectification capacity at Tsp ≤ 115 °C on standard FR4 PCB |
| Forward Voltage | 510 mV typ. @ 2 A - minimizes power loss (1.02 W conduction loss) in high-efficiency SMPS |
| Reverse Leakage | 400 µA typ. @ 30 V - low standby current critical for battery-powered low-power systems |
| Diode Capacitance | 60–72 pF @ 1 V - supports fast switching in >1 MHz DC-DC topologies with minimal ringing |
| Junction Temp Limit | 150 °C - defines maximum thermal headroom before derating in enclosed industrial environments |
Pinout & Package
Encapsulated in the compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm), with cathode marked by a bar on the body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; connected to load/ground side; marking bar identifies this pin |
| 2 | Anode (A) | Input terminal for forward conduction; connects to input rail or switch node in buck/flyback topologies |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD robustness and transient voltage immunity without increasing VF or package size |
| Low thermal resistance to solder point | Rth(j-sp) = 190 K/W enables higher pulsed current handling (IFRM = 4.5 A) with localized heat extraction |
| Optimized for FR4 PCB mounting | Specified power dissipation (660 mW) validated on single-sided tin-plated copper with 1 cm² cathode pad |
| Low capacitance profile | 72 pF max at 1 V reverse bias reduces switching losses and improves EMI behavior in MHz-range converters |
Applications
| USB Power Delivery Adapter | Industrial Sensor Node |
|---|---|
Use Scenario: Secondary-side synchronous rectification in 20–30 V USB PD adapter output stage. IC Role / Device Role / Timing Role: Low-VF Schottky rectifier replacing MOSFETs in cost-sensitive designs where gate drive complexity must be avoided. Use Value: 510 mV VF reduces conduction loss by ~30% vs. standard 1N5819, improving full-load efficiency to >92%. | Use Scenario: Reverse polarity protection for 3.3 V/5 V sensor modules powered by coin-cell or Li-ion batteries. IC Role / Device Role / Timing Role: Series-connected protection diode ensuring system integrity during incorrect battery insertion. Use Value: 400 µA IR at 30 V limits standby drain to <1 µA per module, extending 10-year battery life targets. |
| Point-of-Load DC-DC Converter | Automotive Body Control Module |
Use Scenario: Output rectification in 12 V input → 3.3 V/5 V buck converter for FPGA I/O rails. IC Role / Device Role / Timing Role: Freewheeling path during high-side switch off-time; operates at 500 kHz–1 MHz switching frequencies. Use Value: 60–72 pF capacitance minimizes voltage overshoot and reduces need for snubbers in space-constrained layouts. | Use Scenario: Input protection for 12 V supply rail in non-safety-critical BCM submodules (e.g., mirror control, interior lighting). IC Role / Device Role / Timing Role: Standby-mode reverse-blocking element preventing backfeed from auxiliary circuits. Use Value: Guard ring ensures survivability against load-dump transients up to ISO 7637-2 Pulse 1 (−150 V, 50 ms) when combined with TVS clamping. |
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 SOD123 package; 40 V VR, 2 A IF(AV); VF = 520 mV @ 2 A; IR = 100 µA @ 30 V | Higher reverse voltage margin but lower leakage - better for 36 V nominal systems with infrequent overvoltage events | Select when system requires >30 V transient tolerance and ultra-low standby current is prioritized over minimal VF advantage |
| Vishay SS23 | SOD123 package; 30 V VR, 2 A IF(AV); VF = 500 mV @ 2 A; IR = 500 µA @ 30 V; Cd = 80 pF | Lower VF but higher capacitance - may require additional EMI filtering in >1 MHz converters | Prefer when absolute lowest conduction loss is critical and board area allows for added RC damping |
Compared with NSS40201MUTBG and SS23, PMEG3020EGWJ offers the best balance of low VF (510 mV), moderate leakage (400 µA), and low capacitance (72 pF), making it optimal for space-constrained, high-frequency DC-DC designs requiring stable thermal performance on standard FR4.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The PMEG3020EGWJ has a maximum junction temperature rating of 150 °C. Continuous operation at this limit requires strict thermal management - including use of a 1 cm² cathode copper pad (Rth(j-sp) = 190 K/W) and ambient temperature ≤ 55 °C. Derating curves in the datasheet define safe IF(AV) versus Tsp.
Is PMEG3020EGWJ qualified for automotive applications?
No. Per Nexperia's revision history (v.2, October 2023), PMEG3020EGWJ is explicitly designated as non-automotive. It lacks AEC-Q101 qualification and automotive-grade testing. For automotive use, select the -Q qualified variant (e.g., PMEG3020EGWJ-Q) or equivalent AEC-compliant Schottky rectifiers.
How does the guard ring affect reliability in real-world PCB layouts?
The integrated guard ring improves resistance to edge breakdown during voltage transients and enhances ESD robustness (IEC 61000-4-2 level 4). In practice, it allows the device to withstand repeated 15 kV air-discharge ESD events without parameter shift - critical for unshielded connectors in portable equipment.
Can PMEG3020EGWJ replace a standard 1N5819 in existing designs?
Yes - with identical SOD123 footprint and pinout, PMEG3020EGWJ offers lower VF (510 mV vs. ~550 mV), lower IR (400 µA vs. ~1 mA), and tighter parameter distribution. No layout change is needed, but verify thermal margin since its higher Ptot (660 mW vs. ~500 mW) assumes optimized copper pad area.
