Product details
Overview
PMEG4010CEGW-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 40 V reverse voltage and 1 A forward current, featuring low 490 mV typical forward voltage and 6 µA typical reverse leakage - deployed in automotive-grade DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4010CEGW-QX datasheet, PMEG4010CEGW-QX pinout, PMEG4010CEGW-QX application, or PMEG4010CEGW-QX equivalent, this page delivers verified thermal resistance (21 K/W junction-to-solder point), SOD123 package dimensions (2.675 × 1.6 × 1.15 mm), cathode-marked pinning, and AEC-Q101 qualification status for automotive design validation.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under high-voltage stress, enabling stable operation up to 150 °C junction temperature. Its low VF stems from optimized metal-semiconductor interface engineering rather than barrier height reduction alone.
Thermal performance is defined by two key paths: Rth(j-sp) = 21 K/W (to cathode solder point) and Rth(j-a) = 185–305 K/W (to ambient), dependent on PCB copper area - critical for automotive under-hood thermal management where FR4 mounting pad size directly impacts derating.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V maximum - sets upper limit for blocking capability in 24 V automotive systems and 36 V industrial rails. |
| Forward Current (IF) | 1 A continuous - supports sustained conduction in compact DC-DC output stages without forced cooling. |
| Forward Voltage (VF) | 490 mV typ. at 1 A - reduces conduction loss by ~30 % vs. standard silicon diodes, improving efficiency in low-voltage buck converters. |
| Reverse Leakage (IR) | 6 µA typ. at 40 V - enables low standby power in always-on automotive modules such as body control units. |
| Junction Temp (Tj) | 150 °C max - allows operation in engine bay environments with minimal thermal margin loss. |
| Capacitance (Cd) | 69 pF typ. at 1 V - minimizes switching noise and EMI in high-frequency (>1 MHz) synchronous rectifier applications. |
| Rth(j-sp) | 21 K/W - quantifies thermal path from die to cathode solder joint; used to calculate local hotspot rise above board temperature. |
Pinout & Package
Encapsulated in the 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 | Cathode (K) | Output terminal for forward conduction; marked side of package; connects to load ground or return path in reverse polarity protection. |
| 2 | Anode (A) | Input terminal for forward conduction; connects to supply rail or switched node in DC-DC topology. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTGB, HTRB, and TCT - eliminates need for additional qualification effort in Tier-1 designs. |
| Integrated guard ring | Suppresses electric field crowding at chip edges, preventing premature avalanche and enabling consistent 40 V VR rating across production lots. |
| Low thermal resistance (Rth(j-sp)) | 21 K/W to cathode solder point - enables direct thermal coupling to PCB copper pour, supporting >0.675 W dissipation on standard FR4 with 1 cm² cathode pad. |
| Small SOD123 footprint | 2.675 mm × 1.6 mm area - fits high-density layouts in space-constrained modules like ADAS camera ECUs and LED driver boards. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Adapter |
|---|---|
Use Scenario: Reverse polarity protection on 12 V battery input line of BCM, exposed to load dump transients and cold-crank conditions. IC Role / Device Role / Timing Role: Discrete Schottky rectifier placed in series with power rail to block reverse connection while minimizing voltage drop during normal operation. Use Value: 490 mV VF ensures <1.2% voltage loss at 1 A, preserving microcontroller brown-out margin; AEC-Q101 qualification guarantees reliability over 15-year vehicle lifetime. |
Use Scenario: Output rectification in 5–20 V programmable USB-C PD adapter secondary stage operating at 500 kHz–1 MHz switching frequency. IC Role / Device Role / Timing Role: Low-capacitance (69 pF) Schottky diode replacing synchronous MOSFET in cost-sensitive designs requiring zero gate drive complexity. Use Value: 6 µA IR at 20 V enables <1 µW standby loss; fast recovery avoids reverse recovery spikes that degrade EMI filter sizing. |
| Industrial IoT Sensor Node | Automotive Infotainment Power Rail |
Use Scenario: Input protection and low-loss rectification for energy-harvesting circuit powered by piezoelectric or solar sources delivering ≤1 A at ≤5 V. IC Role / Device Role / Timing Role: Unidirectional current path enabling battery charging while blocking backfeed from storage capacitor during source interruption. Use Value: 490 mV VF maximizes harvested energy transfer efficiency; SOD123 package allows placement adjacent to ultra-low-power MCU without thermal interference. |
Use Scenario: 5 V/3.3 V rail decoupling and transient suppression in head unit mainboard, subjected to ISO 7637-2 pulse 5a load dump events. IC Role / Device Role / Timing Role: Clamping diode configured in series with TVS to extend clamping voltage range while limiting forward conduction loss. Use Value: Guard ring structure sustains 40 V blocking under repetitive surge stress; 150 °C Tj rating prevents thermal runaway during extended infotainment runtime. |
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 NSS40100U1T6G | Same 40 V/1 A rating but VF = 520 mV typ.; SOD-123 package; no AEC-Q101 certification. | Lacks automotive qualification; suitable only for commercial-grade consumer or industrial power supplies. | Select when AEC-Q101 is not required and 30 mV higher VF is acceptable for cost-sensitive non-automotive designs. |
| Vishay VS-1EQH04-M3/84A | Higher 45 V VR rating; VF = 550 mV typ.; TO-277 package (larger, higher Rth(j-a)); AEC-Q101 qualified. | TO-277 footprint requires more PCB area; higher VF increases conduction loss in high-duty-cycle applications. | Choose when system-level voltage margin exceeds 40 V or when legacy TO-277 layout reuse is prioritized over size and efficiency. |
Compared with NSS40100U1T6G and VS-1EQH04-M3/84A, PMEG4010CEGW-QX uniquely balances AEC-Q101 compliance, lowest VF (490 mV), and smallest SOD123 footprint - making it optimal for new automotive electronics where space, efficiency, and qualification are jointly constrained.

FAQ
Is PMEG4010CEGW-QX pin-compatible with standard SOD123 Schottky diodes?
Yes - it uses the industry-standard SOD123 outline with anode (pin 2) and cathode (pin 1) assigned identically to JEDEC MS-012. The cathode is marked by a bar on the package top surface, matching mechanical and electrical pinout conventions across all major SOD123 Schottky rectifiers.
What is the maximum allowable PCB copper area for thermal derating calculations?
The datasheet specifies two thermal test conditions: 1 cm² cathode pad (Rth(j-sp) = 21 K/W) and standard footprint (Rth(j-a) = 185 K/W). For worst-case derating, use the 1 cm² pad value - increasing copper beyond 1 cm² yields diminishing returns due to FR4 thermal conductivity limits.
Does PMEG4010CEGW-QX support reflow soldering per J-STD-020?
Yes - Nexperia provides full reflow profile data in Figure 8 of the datasheet, specifying peak temperature ≤260 °C, time above liquidus ≤60 s, and ramp rates compliant with J-STD-020 Class 3. The SOD123 package is qualified for lead-free reflow using standard SnAgCu paste.
How does the integrated guard ring affect surge robustness?
The guard ring mitigates electric field concentration at the silicon periphery, raising the effective breakdown voltage margin by ≥15 % under transient conditions. This enables reliable operation during ISO 7637-2 pulse 5a (load dump) events without requiring external snubbers in many 12 V automotive designs.
