Product details
Overview
PMEG4010CEH-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 a very low 490–570 mV forward voltage at 1 A, housed in an AEC-Q101-qualified SOD123F surface-mount package for automotive-grade low-voltage rectification.
For engineers reviewing the PMEG4010CEH-QX datasheet, PMEG4010CEH-QX pinout, PMEG4010CEH-QX application, or PMEG4010CEH-QX equivalent, key selection criteria include its ultra-low VF performance at high current, AEC-Q101 qualification, thermal resistance (Rth(j-sp) = 150 K/W), and suitability for space-constrained DC-DC converters requiring reverse polarity protection.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability under repetitive surge conditions. Its low VF stems from optimized metal-semiconductor interface design, enabling high conduction efficiency without compromising reverse leakage.
Thermal performance is defined by two mounting configurations: Rth(j-a) = 330 K/W on standard FR4 and Rth(j-sp) = 150 K/W with extended cathode pad, directly supporting thermal management in automotive power rails where ambient temperatures reach 125 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability for 12 V/24 V automotive systems with transient margin. |
| Forward Current (IF) | 1 A continuous - Supports steady-state operation in compact DC-DC output stages and load switches. |
| Forward Voltage (VF) | 490–570 mV @ 1 A - Reduces conduction loss by >30% vs. standard silicon diodes, improving system efficiency. |
| Reverse Leakage (IR) | 6–50 µA @ 40 V - Low leakage preserves battery life in always-on automotive modules. |
| Diode Capacitance (Cd) | 69–77 pF @ 1 V - Enables fast switching in high-frequency SMPS (>500 kHz) with minimal ringing. |
| Junction Temperature (Tj) | 150 °C - Allows operation in engine bay environments without derating at full current. |

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-M3/5AT | Higher VF (620 mV typ @ 1 A); same 40 V rating; TO-277 package (larger, higher Rth). | Less suitable for space-constrained automotive modules; better for industrial boards with thermal vias. | Select if board layout allows larger footprint and higher thermal resistance is acceptable. |
| ON Semiconductor NSR0140HT1G | Lower IR (1 µA @ 40 V); same VF range; SOD-123 package (no guard ring; non-AEC-Q101). | Not qualified for automotive use; limited surge robustness in harsh ESD environments. | Select only for consumer-grade portable devices where AEC-Q101 is not required. |
Compared with VS-1EQH04-M3/5AT and NSR0140HT1G, PMEG4010CEH-QX uniquely combines AEC-Q101 qualification, guard ring protection, and lowest VF in SOD123F-making it optimal for automotive and space-limited high-efficiency rectification where reliability and thermal density are critical.

FAQ
Is PMEG4010CEH-QX suitable for synchronous rectification in DC-DC converters?
Yes - its 490–570 mV forward voltage at 1 A and 77 pF capacitance enable efficient freewheeling operation in buck converters up to 1 MHz. It replaces MOSFETs in cost-sensitive designs where gate drive complexity must be avoided, while maintaining low conduction loss and minimal switching noise.
What is the maximum allowable soldering temperature profile for PMEG4010CEH-QX?
The SOD123F package supports standard lead-free reflow per JEDEC J-STD-020: peak temperature ≤ 260 °C, time above 217 °C ≤ 60 seconds, and ramp rate ≤ 3 °C/s. The device's thermal resistance data assumes tin-plated FR4 with specified solder land geometry (2.8 mm × 1.6 mm cathode pad).
Does the guard ring affect the device's electrical parameters?
No - the guard ring is a passive structural feature surrounding the active junction to suppress edge breakdown; it does not alter forward voltage, leakage current, or capacitance. Its function is purely mechanical/electrical stress mitigation, verified through AEC-Q101 HBM/CDM/ESD testing.
Can PMEG4010CEH-QX replace a standard 1N5819 in existing designs?
Yes - it shares identical SOD123F footprint and pinout, but offers lower VF (vs. 450–600 mV for 1N5819), tighter leakage control (6–50 µA vs. 100–500 µA), and AEC-Q101 qualification. No layout change is needed, though thermal validation is recommended due to higher current density.
