Product details
Overview
PMEG3020EGW-QJ from Nexperia is a 30 V, 2 A planar Schottky barrier rectifier in SOD123 package, featuring low forward voltage (510 mV typ. at 2 A), low reverse leakage (400 µA typ. at 30 V), and AEC-Q101 qualification for automotive use - deployed in reverse polarity protection and DC-DC converter output stages.
For engineers reviewing the PMEG3020EGW-QJ datasheet, PMEG3020EGW-QJ pinout, PMEG3020EGW-QJ application, or PMEG3020EGW-QJ equivalent, key selection criteria include VF/IR trade-off at 25–125 °C, thermal resistance to solder point (190 K/W), and SOD123 footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode uses a planar junction with integrated guard ring for robust ESD and surge stress protection. Its low VF stems from optimized metal-semiconductor interface design, enabling efficient conduction at low voltages without minority-carrier storage delay.
Thermal performance is defined by two distinct Rth paths: 310 K/W (junction-to-ambient, standard footprint) and 190 K/W (junction-to-solder point, 1 cm² cathode pad), directly impacting continuous current derating in automotive under-hood environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 510 mV typ. at 2 A, 25 °C - enables <1.0 W conduction loss in 5 V/2 A rail applications |
| Reverse Leakage (IR) | 400 µA typ. at 30 V, 25 °C - limits standby power loss in battery-backed systems |
| Peak Repetitive Current (IFRM) | 4.5 A at 1 ms pulse - supports transient load surges in automotive DC-DC converters |
| Junction Temperature (Tj) | 150 °C max - allows operation in engine control units with ambient up to 125 °C |
| Diode Capacitance (Cd) | 60 pF typ. at 1 V, 1 MHz - minimizes switching noise in high-frequency SMPS outputs |
| Thermal Resistance (Rth(j-sp)) | 190 K/W - requires ≥1 cm² copper pad on cathode for full 2 A continuous rating |
Pinout & Package
Encapsulated in 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) | Connected to output rail or ground return; carries full forward current and dissipates majority of heat via solder pad |
| 2 | Anode (A) | Connected to input or switched node; voltage referenced to cathode defines reverse blocking capability (30 V) |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD per JESD22-A114 |
| Guard ring integration | Prevents edge breakdown under high dv/dt or mechanical stress, improving long-term field robustness |
| Low thermal resistance to solder point | 190 K/W enables 2 A continuous operation with minimal board area - no heatsink required |
| Small SOD123 footprint | Compatible with 0805-class pick-and-place equipment and high-density routing in ADAS ECUs |
Applications
| Automotive Body Control Module | USB-C Power Delivery Adapter |
|---|---|
Use Scenario: Reverse polarity protection on 12 V supply rail feeding microcontroller and CAN transceiver. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection.

Use Value: 150 °C Tj rating supports operation inside sealed headlamp housings with ambient >105 °C. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EY30-M3/54 | Same 30 V/2 A rating but VF = 540 mV min (vs. 510 mV typ.), IR = 1 mA max (vs. 400 µA typ.) | Higher IR increases standby loss in always-on battery systems; less suitable for ultra-low-power IoT nodes | Select when cost sensitivity outweighs 30 µV VF advantage and AEC-Q101 is not required |
| ON Semiconductor NSR20F30NXT5G | VF = 490 mV typ. at 2 A, but only rated to 125 °C Tj (vs. 150 °C) and not AEC-Q101 qualified | Limited high-temp reliability in under-hood automotive use; acceptable for consumer power adapters | Prefer for non-automotive designs needing lowest possible VF, where thermal margin is ample |
Compared with VS-2EY30-M3/54 and NSR20F30NXT5G, PMEG3020EGW-QJ delivers the best combination of low VF, low IR, 150 °C junction rating, and AEC-Q101 compliance - making it the default choice for automotive power rails where reliability and efficiency are jointly critical.

FAQ
What is the maximum continuous forward current for PMEG3020EGW-QJ at 115 °C solder point temperature?
The datasheet specifies an average forward current (IF(AV)) of 2 A at Tsp ≤ 115 °C with δ = 0.5 duty cycle and 20 kHz square wave. This rating assumes FR4 PCB with standard SOD123 footprint and no additional heatsinking. Derating is required above this temperature.
Does PMEG3020EGW-QJ have a built-in guard ring, and what function does it serve?
Yes - the device integrates a planar guard ring structure around the Schottky junction. It prevents premature edge breakdown under high electric field stress, improving ruggedness against voltage transients and mechanical strain during board flexure or thermal cycling.
Can PMEG3020EGW-QJ be used in place of a standard silicon diode in a 12 V automotive circuit?
Yes, provided reverse voltage does not exceed 30 V. Its 510 mV forward voltage cuts conduction loss by ~65% versus a typical 1N4007 (VF ≈ 1.1 V), reducing heat generation and improving system efficiency - especially beneficial in thermally constrained ECUs.
What is the significance of the "QJ" suffix in PMEG3020EGW-QJ?
The "QJ" suffix denotes Nexperia's automotive-grade variant with full AEC-Q101 qualification, including extended temperature testing (−55 °C to +150 °C), humidity robustness, and lifetime reliability validation - distinct from commercial-grade "Q" versions.
