Product details
Overview
PMEG3020EGW115 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 PMEG3020EGW115 datasheet, PMEG3020EGW115 pinout, PMEG3020EGW115 application, or PMEG3020EGW115 equivalent, key selection criteria include VF vs. IF trade-off at 25 °C and 150 °C, thermal resistance to solder point (190 K/W), SOD123 footprint compatibility, and non-automotive qualification status.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance surge robustness and reduce field crowding at the junction edge. Its low VF stems from optimized metal-semiconductor interface engineering rather than barrier height reduction alone.
Thermal performance is defined relative to two PCB mounting conditions: standard SOD123 footprint (Rth(j-a) = 310 K/W) and enhanced cathode pad (1 cm², Rth(j-sp) = 29 K/W), enabling accurate power derating in compact power stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability without breakdown under steady-state DC or pulsed conditions at Tj = 25 °C. |
| Average Forward Current (IF(AV)) | 2 A - Sustained DC or square-wave current handling at δ = 0.5, f = 20 kHz, with solder point ≤ 115 °C. |
| Forward Voltage (VF) | 510 mV typ. at IF = 2 A - Directly reduces conduction loss in high-efficiency buck converters and OR-ing circuits. |
| Reverse Current (IR) | 400 µA typ. at VR = 30 V - Low leakage preserves battery life in always-on low-power systems. |
| Diode Capacitance (Cd) | 60–72 pF at VR = 1 V, f = 1 MHz - Limits switching speed impact in high-frequency SMPS output rectification. |
| Junction Temperature (Tj) | 150 °C max - Defines maximum operating junction temperature before permanent degradation. |
| Thermal Resistance (Rth(j-sp)) | 190 K/W - Enables thermal modeling from junction to cathode solder point on FR4 with 1 cm² copper pad. |
Pinout & Package
Encapsulated in a compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode marked by a bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; connected to output rail or ground return path in rectifier and reverse polarity protection configurations. |
| 2 | Anode (A) | Positive terminal; accepts input voltage source or switched node in synchronous rectifier replacement applications. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves ESD and transient overvoltage immunity without increasing VF or leakage - critical for unregulated input interfaces. |
| Low VF at high IF | 510 mV @ 2 A enables >95 % efficiency in 5 V → 3.3 V buck converters at full load. |
| SOD123 footprint | Standardized 2.675 mm × 1.6 mm outline allows drop-in replacement in space-constrained portable designs. |
| Non-automotive qualified | Released per industrial-grade reliability standards; not tested to AEC-Q101 - intended for consumer, computing, and industrial power supplies. |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Used as secondary-side rectifier in 500 kHz synchronous buck converter powering FPGA core voltage. IC Role / Device Role / Timing Role: Uncontrolled rectifying element replacing MOSFET body diode during dead-time, minimizing conduction loss. Use Value: 510 mV VF cuts conduction loss by ~40 % versus standard silicon diodes, directly improving thermal margin at 2 A load. | Use Scenario: Placed in series with VIN rail of USB-powered IoT sensor node to prevent damage from reversed adapter insertion. IC Role / Device Role / Timing Role: Series-blocking diode that conducts only when polarity is correct, with minimal voltage drop. Use Value: 510 mV forward drop preserves >98 % of 5 V supply headroom - critical for brownout-sensitive microcontrollers. |
| Low-Voltage AC/DC Adapter | Load Switch Back-Drive Protection |
Use Scenario: Output rectifier in 12 V AC input, 5 V/2 A flyback adapter for smart home hubs. IC Role / Device Role / Timing Role: Primary unidirectional current path converting transformer secondary AC to regulated DC output. Use Value: 400 µA IR at 30 V ensures <1 µW standby loss - meets Energy Star Level VI no-load power requirements. | Use Scenario: Placed between two independently powered subsystems (e.g., MCU domain and motor driver domain) sharing a common ground. IC Role / Device Role / Timing Role: Prevents back-feed current from higher-voltage domain into lower-voltage domain during power sequencing faults. Use Value: Guard ring structure withstands 30 V reverse transients without latch-up, ensuring fail-safe isolation during hot-plug events. |
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 NSS30201MR6T1G | Same SOD123 package, 30 V/2 A rating, but VF = 520 mV typ. at 2 A and IR = 500 µA typ. at 30 V. | Identical use cases; slightly higher leakage may affect ultra-low-power battery hold-up time. | Select if dual-sourcing required and ON Semi's supply chain alignment is prioritized. |
| Vishay SS23 | SOD-123 package, 30 V/2 A, VF = 500 mV typ. at 2 A, but IR = 1 mA typ. at 30 V - 2.5× higher leakage. | Acceptable in non-battery-critical applications; unsuitable for always-on sensors due to increased standby drain. | Prefer for cost-sensitive consumer adapters where leakage is not constrained. |
Compared with NSS30201MR6T1G and SS23, PMEG3020EGW115 delivers the lowest IR (400 µA) among the three, making it optimal for energy-harvesting and battery-backed systems where microamp-level leakage directly impacts runtime.

FAQ
Is PMEG3020EGW115 automotive-qualified?
No. Per Nexperia's revision history (v.2, October 2023), this part is explicitly designated as non-automotive. It lacks AEC-Q101 qualification and is intended for industrial, computing, and consumer applications only. Automotive designs require variants suffixed with "-Q", such as PMEG3020EGW-Q.
What is the meaning of the marking code "G3" on the device body?
The marking "G3" is the manufacturer-specific identifier for PMEG3020EGW, as confirmed in Table 4 of the datasheet. It is laser-marked on the cathode side and serves as a visual verification tool during assembly and inspection - distinct from date codes or lot identifiers.
Can PMEG3020EGW115 replace a standard PN-junction diode in a 5 V linear regulator output?
Yes, but only where reverse leakage and thermal rise are not limiting. With 400 µA IR at 30 V and 510 mV VF, it reduces dropout voltage and improves efficiency versus 1N400x-series diodes. However, its 150 °C Tj limit requires careful thermal design - unlike PN diodes, it cannot tolerate sustained reverse bias near VR without self-heating risk.
How does the guard ring affect surge performance?
The integrated guard ring mitigates electric field concentration at the junction periphery, raising the device's ability to withstand repetitive 30 V transients without degradation. This is validated in Nexperia's stress testing protocol (IEC 61000-4-5 compliant surge waveforms), enabling reliable operation in unfiltered input rails without external TVS supplementation.
