Product details
Overview
PMEG4010EGW-QJ from Nexperia is a 40 V, 1 A planar MEGA Schottky barrier rectifier in SOD123 package, featuring low forward voltage (540 mV typ. at 1 A), low reverse leakage (30 µA typ. at 40 V), and AEC-Q101 qualification for automotive-grade reliability-used in reverse polarity protection and high-efficiency DC-DC conversion stages.
For engineers reviewing the PMEG4010EGW-QJ datasheet, PMEG4010EGW-QJ pinout, PMEG4010EGW-QJ application, or PMEG4010EGW-QJ equivalent, key selection criteria include forward voltage drop under 1 A load, thermal resistance to solder point (190 K/W), junction temperature limit (150 °C), and AEC-Q101 compliance for harsh-environment deployment.
Technical Context
This Schottky rectifier uses a planar MEGA structure with integrated guard ring for enhanced ESD and surge robustness. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer, enabling high conduction efficiency at low voltages.
Designed for unidirectional current flow in low-voltage power rails, it operates with zero minority-carrier storage delay and exhibits minimal reverse recovery charge-critical for high-frequency switching topologies like synchronous buck converters and automotive body control modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 40 V max - defines maximum blocking capability in reverse-biased operation without breakdown. |
| Forward Current | 1 A continuous - supports sustained conduction in low-voltage rectification paths up to ambient 55 °C. |
| Forward Voltage | 540 mV typ. at 1 A - reduces conduction loss by ~30% vs. standard silicon diodes, improving system efficiency. |
| Reverse Current | 30 µA typ. at 40 V - ensures minimal leakage in standby or reverse-polarity protection circuits. |
| Junction Temp | 150 °C max - enables operation in under-hood automotive environments with localized heating. |
| Thermal Rth(j-sp) | 190 K/W - quantifies heat transfer from die to cathode solder point on FR4 PCB, guiding thermal pad design. |
| Diode Capacitance | 43 pF typ. at 1 V - limits high-frequency switching noise and affects snubberless flyback performance. |
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 device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Output terminal for forward conduction; connected to ground or low-side return path in rectifier configurations. |

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-1EQH04-M3/5BT | 45 V VR, 1 A IF, VF = 550 mV typ., no AEC-Q101 certification | Qualified for industrial but not automotive use; higher VR margin at cost of slightly larger SOD-123W footprint | Select when higher reverse margin is prioritized over automotive qualification and board space is less constrained. |
| ON Semiconductor NSR0140HT1G | 40 V VR, 1 A IF, VF = 450 mV typ., AEC-Q101 qualified, SOD-123 package | Lower VF improves efficiency but exhibits 120 µA IR at 40 V-3.5× higher leakage than PMEG4010EGW-QJ | Prefer where ultra-low conduction loss dominates over leakage-sensitive standby modes. |
Compared with VS-1EQH04-M3/5BT and NSR0140HT1G, PMEG4010EGW-QJ delivers optimal balance of AEC-Q101 compliance, 540 mV VF, and 30 µA IR-making it ideal for automotive power rails requiring both efficiency and low-quiescent leakage.

FAQ
What is the maximum allowable junction temperature for PMEG4010EGW-QJ?
The absolute maximum junction temperature is 150 °C, as specified in the limiting values table. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating is required above 125 °C ambient, especially under 1 A continuous load, due to thermal resistance of 190 K/W to solder point.
Is PMEG4010EGW-QJ suitable for synchronous rectification?
No-it is a passive Schottky rectifier, not a controlled MOSFET-based synchronous rectifier IC. However, its low VF and zero reverse recovery make it well-suited as a freewheeling diode in non-synchronous buck or flyback converters operating up to several hundred kHz.
How does the guard ring improve reliability?
The integrated guard ring mitigates electric field concentration at the die edge, raising the effective breakdown voltage under transient stress and improving robustness against ESD (IEC 61000-4-2) and load-dump surges common in automotive 12 V systems.
What is the meaning of the 'QJ' suffix in PMEG4010EGW-QJ?
The 'QJ' suffix denotes Nexperia's automotive-grade variant with full AEC-Q101 qualification, traceable lot documentation, and extended temperature screening-distinct from commercial-grade 'Q' versions which lack automotive test reporting and process controls.
