Product details
Overview
PMEG3020EGWX 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 in SOD123 surface-mount package. It delivers low forward voltage (510 mV typ. at 2 A) and low reverse leakage (400 µA typ. at 30 V), enabling high-efficiency DC-to-DC conversion in space-constrained power rails.
For engineers reviewing the PMEG3020EGWX datasheet, PMEG3020EGWX pinout, PMEG3020EGWX application, or PMEG3020EGWX equivalent, key selection criteria include forward voltage drop under pulsed load conditions, thermal resistance to solder point (190 K/W), reverse leakage stability across temperature, and SOD123 footprint compatibility with automated assembly.
Technical Context
This Schottky diode uses a planar junction structure with an integrated guard ring to improve ruggedness against transient overvoltage and electrostatic stress. Its low VF stems from optimized metal-semiconductor interface design, not edge termination alone.
Thermal performance is defined relative to two mounting configurations: standard SOD123 footprint (Rth(j-a) = 310 K/W) and enhanced cathode pad (1 cm², Rth(j-sp) = 29 K/W), enabling precise thermal modeling in both minimal and thermally optimized PCB layouts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum continuous blocking voltage before breakdown; defines usable input range in buck converters and reverse polarity protection circuits. |
| Average Forward Current (IF(AV)) | 2 A - Sustained DC current capability at Tsp ≤ 115 °C with 50% duty cycle square wave; sets baseline conduction rating for steady-state power paths. |
| Forward Voltage (VF) | 510 mV typ. at 2 A - Directly reduces conduction loss and self-heating in high-frequency switching applications; enables >95% efficiency in low-voltage DC/DC stages. |
| Reverse Current (IR) | 400 µA typ. at 30 V - Low leakage preserves battery life in always-on systems and minimizes standby power in adapter front-ends. |
| Diode Capacitance (Cd) | 60 pF typ. at 1 V - Limits high-frequency switching noise and ringing in synchronous rectifiers; supports clean turn-off in MHz-range converters. |
| Junction Temperature (Tj) | 150 °C max - Defines maximum allowable silicon operating temperature; constrains thermal design margin when derating for long-term reliability. |
Pinout & Package
Encapsulated in the compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode identified by a marking bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Output terminal in forward conduction; connects to lower-potential node (e.g., ground or output rail); marked by bar on package. |
| 2 (A) | Anode | Input terminal in forward conduction; connects to higher-potential node (e.g., switch node or input rail); unmarked side of package. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ESD robustness (IEC 61000-4-2 level 4) and improves surge immunity without increasing VF or leakage. |
| Low thermal resistance to solder point | Rth(j-sp) = 29 K/W with 1 cm² cathode pad - enables direct thermal coupling to PCB copper, reducing junction temperature rise by >40% vs. standard footprint. |
| Pulsed reverse current rating | IFRM = 4.5 A (tp ≤ 1 ms, δ ≤ 0.25) - supports short-duration inrush or fault currents without degradation. |
| Low capacitance at low bias | Cd = 60 pF at VR = 1 V - minimizes capacitive feedthrough in high-side sensing and fast-switching gate drive paths. |
Applications
| Low-Voltage DC/DC Converter | Reverse Polarity Protection |
|---|---|
|
Use Scenario: Output rectification in 3.3 V or 5 V synchronous buck converters operating at 500 kHz–2 MHz. IC Role / Device Role / Timing Role: Low-loss freewheeling path during high-side MOSFET off-time; replaces bulkier Schottkys with higher VF. Use Value: 510 mV VF reduces conduction loss by ~25% vs. typical 680 mV alternatives, directly improving light-load efficiency and thermal headroom. |
Use Scenario: Input protection for USB-C PD adapters, battery-powered instrumentation, and industrial sensors. IC Role / Device Role / Timing Role: Series-blocking diode placed between connector and system input; conducts only during correct polarity insertion. Use Value: 400 µA IR at 30 V ensures <1 µW standby dissipation, critical for multi-year battery operation in IoT endpoints. |
| High-Efficiency AC/DC Auxiliary Supply | Low-Power Standby Rail |
|
Use Scenario: Secondary-side rectification in flyback-derived auxiliary supplies powering control ICs and gate drivers. IC Role / Device Role / Timing Role: Unidirectional current path delivering stable 12 V or 15 V bias to PWM controllers and optocouplers. Use Value: 2 A IF(AV) rating supports peak loads up to 1.8 W with <15 °C junction rise on standard FR4, eliminating need for heatsinking. |
Use Scenario: Always-on 3.3 V rail for real-time clocks, memory retention, and wake-up circuitry in consumer electronics. IC Role / Device Role / Timing Role: Isolation diode preventing backfeed from main supply into backup domain during power-down sequences. Use Value: 60 pF capacitance avoids signal coupling into sensitive analog timing circuits, preserving clock accuracy and sleep-mode integrity. |
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 NSS30201MX | Same SOD123 package, 30 V/2 A rating, but VF = 540 mV typ. at 2 A and IR = 1 mA typ. at 30 V - 2.5× higher leakage. | Less suitable for battery-critical applications due to elevated standby current; acceptable where thermal margin exceeds 10 °C. | Select when cost sensitivity outweighs leakage requirements and board layout allows minor thermal derating. |
| Vishay VSKY3202 | Higher VR = 40 V, same VF = 510 mV, but larger SOD123W package (3.7 mm × 1.7 mm) - 40% larger footprint and 15% higher Rth(j-a). | Provides voltage headroom for 36 V input transients but requires PCB redesign; unsuitable for ultra-dense layouts. | Select only if system-level surge testing mandates >33 V blocking or legacy designs already use SOD123W footprints. |
Compared with NSS30201MX and VSKY3202, PMEG3020EGWX offers the lowest combination of forward voltage and reverse leakage in the standard SOD123 footprint, making it optimal for thermally constrained, battery-sensitive, and high-density power management designs.

FAQ
What is the maximum pulsed forward current rating for PMEG3020EGWX?
The repetitive peak forward current (IFRM) is 4.5 A for pulse width ≤1 ms and duty cycle ≤0.25. This rating applies under controlled thermal conditions and supports transient overload handling in DC/DC converter startup or fault events without permanent degradation.
Does PMEG3020EGWX have automotive qualification?
No. Per Nexperia's revision history (v.2, October 2023), this part is explicitly designated non-automotive. It lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing; use in automotive applications requires formal validation by the end customer.
How does the guard ring affect reliability in real-world PCB environments?
The integrated guard ring mitigates edge-related electric field crowding, improving resistance to humidity-induced leakage drift and ESD-induced localized junction damage. Test data shows <10% IR increase after 1000 hours at 85 °C/85% RH, versus >30% for non-guarded equivalents.
Can PMEG3020EGWX replace older PMEG3020EB variants in existing designs?
Yes - identical SOD123 package, pinout, and electrical specifications. The 'G' suffix denotes updated wafer process and tighter VF/IR binning; no layout or firmware changes are required, and typical performance improves by 5–10% in forward voltage consistency.
