Product details
Overview
PMEG4010EH-QX from Nexperia is a 40 V, 1 A planar Schottky barrier rectifier in SOD123F package, featuring 540–640 mV forward voltage at 1 A and ≤100 µA reverse leakage at 40 V. It integrates a guard ring for stress protection and is qualified to AEC-Q101 for automotive-grade reliability in low-voltage DC/DC conversion and reverse polarity protection circuits.
For engineers reviewing the PMEG4010EH-QX datasheet, PMEG4010EH-QX pinout, PMEG4010EH-QX application, or PMEG4010EH-QX equivalent, key selection criteria include its ultra-low VF, AEC-Q101 qualification, thermal resistance (Rth(j-a) = 330 K/W), SOD123F footprint compatibility, and suitability for space-constrained automotive power rails.
Technical Context
This Schottky rectifier uses a planar die structure with integrated guard ring to suppress edge breakdown and improve surge robustness under repetitive and non-repetitive peak currents (IFRM = 7 A, IFSM = 9 A). Its low junction-to-ambient thermal resistance (330 K/W) enables operation up to 150 °C junction temperature on standard FR4 PCBs.
The device delivers stable forward voltage across temperature (−40 °C to 150 °C) and exhibits low diode capacitance (43–50 pF at 1 V), supporting high-frequency switching in buck converters and load-switching applications where fast recovery and minimal switching loss are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 540–640 mV at 1 A - enables <1.5 W conduction loss in 1 A rail, reducing heat sink requirements |
| Reverse Voltage (VR) | 40 V - supports 12 V and 24 V automotive systems with 2× safety margin |
| Reverse Leakage (IR) | ≤100 µA at 40 V / 25 °C - minimizes standby power loss in always-on modules |
| Diode Capacitance (Cd) | 43–50 pF at 1 V / 1 MHz - limits high-frequency displacement current in SMPS feedback paths |
| Junction-to-Ambient Rth | 330 K/W - allows ~375 mW power dissipation at 25 °C ambient without forced cooling |
| Peak Forward Surge (IFSM) | 9 A (8 ms square wave) - withstands cold-crank and load-dump transients in automotive ECUs |
| AEC-Q101 Qualified | Yes - certified for automotive use per stress test qualification for discrete semiconductors |
Pinout & Package
Encapsulated in a compact SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm body), with tin-plated leads and reflow-soldering only process compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connects to ground or return path; larger copper pad required (1 cm²) for thermal management |
| 2 | Anode (A) | Positive input terminal; carries full forward current; polarity-sensitive placement critical for reverse polarity protection |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown under high dv/dt and mechanical stress, improving long-term reliability in vibration-prone automotive environments |
| Ultra-low forward voltage | 540 mV typical at 1 A reduces conduction loss by >30% vs. standard Schottkys, extending battery runtime in low-power modules |
| AEC-Q101 qualification | Validated for automotive temperature cycling, HTRB, HTGB, and ESD per AEC standard - eliminates need for additional qualification testing |
| Low thermal resistance | Rth(j-sp) = 60 K/W to cathode solder point - enables efficient heat transfer to PCB copper, supporting high-density layouts |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VSKY140-E3/54T | 40 V, 1 A; VF = 550 mV typ; no AEC-Q101 qualification; TO-277 package (larger than SOD123F) | Suitable for industrial/commercial designs without automotive qualification mandates | Select when board space is less constrained and AEC-Q101 is not required; verify thermal performance on FR4 with larger footprint |
| ON Semiconductor NSR0140P2T5G | 40 V, 1 A; VF = 450 mV typ; AEC-Q101 qualified; SOD-123 package (slightly larger body than SOD123F) | Better VF but higher cost; requires updated stencil design due to 2.8 mm × 1.8 mm outline | Prefer for ultra-low-loss priority in space-tolerant automotive modules; confirm solder paste volume compatibility with revised land pattern |
Compared with VSKY140-E3/54T and NSR0140P2T5G, PMEG4010EH-QX uniquely balances AEC-Q101 compliance, SOD123F miniaturization, and 540 mV VF-making it optimal for high-volume automotive ECUs where footprint, qualification, and thermal efficiency are jointly constrained.

FAQ
Is PMEG4010EH-QX compatible with lead-free reflow soldering processes?
Yes - the device is qualified exclusively for reflow soldering per J-STD-020, with peak temperature up to 260 °C. Hand soldering and wave soldering are not recommended. The SOD123F package uses matte tin-plated leads compatible with standard SAC305 paste profiles and IPC-A-610 Class 2/3 assembly standards.
What is the maximum continuous forward current at 85 °C ambient?
At Tamb = 85 °C, the maximum continuous forward current is derated to approximately 0.65 A based on thermal resistance (Rth(j-a) = 330 K/W) and Tj(max) = 150 °C. This assumes standard FR4 PCB with single-sided 1 oz copper and no additional heatsinking.
Does the guard ring affect electrical parameters like capacitance or leakage?
No - the guard ring is a passive structural feature surrounding the active junction to prevent premature edge breakdown. It does not alter nominal Cd (43–50 pF) or IR (≤100 µA), but improves long-term stability of those parameters under mechanical stress and high dv/dt conditions.
Can PMEG4010EH-QX replace PMEG4010EH in existing designs?
Yes - PMEG4010EH-QX is the automotive-qualified variant of PMEG4010EH, sharing identical electrical specs, SOD123F package, and pinout. The "-QX" suffix denotes AEC-Q101 qualification and enhanced traceability; no layout or schematic changes are needed for drop-in replacement in automotive designs.
