Product details
Overview
PMEG2010EH-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1 A forward current, featuring a typical forward voltage of 420 mV at 1 A (25 °C, pulsed), housed in an AEC-Q101-qualified SOD123F package for automotive-grade low-voltage rectification.
For engineers reviewing the PMEG2010EH-QX datasheet, PMEG2010EH-QX pinout, PMEG2010EH-QX application, or PMEG2010EH-QX equivalent, key selection criteria include its ultra-low VF performance, thermal resistance (Rth(j-sp) = 150 K/W), reverse leakage (≤40 µA at 20 V), diode capacitance (66–80 pF), and AEC-Q101 qualification for automotive power rails.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to enhance robustness against electrical overstress and ESD transients. Its low forward voltage stems from optimized metal-semiconductor junction design, enabling high efficiency in low-voltage DC/DC stages.
Thermal performance is defined relative to PCB mounting: Rth(j-a) = 330 K/W on standard FR4, improving to 150 K/W when the cathode pad is extended to 1 cm² - critical for sustained 1 A operation in compact automotive modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - supports 12 V automotive systems with margin for load dump transients |
| Forward Current (IF) | 1 A continuous - suitable for point-of-load converters up to ~12 W at 12 V input |
| Forward Voltage (VF) | 420 mV typ. @ 1 A - reduces conduction loss by >40% vs. standard silicon diodes |
| Reverse Leakage (IR) | 40 µA max. @ 20 V - minimizes standby power loss in always-on circuits |
| Diode Capacitance (Cd) | 66–80 pF @ 1 V - enables fast switching with low ringing in SMPS freewheel paths |
| Junction Temp (Tj) | 150 °C max - allows operation in under-hood environments without derating |
| AEC-Q101 Qualified | Yes - validated for automotive applications including body control modules and infotainment power supplies |
Pinout & Package
Encapsulated in the SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm), with standardized footprint per Figure 6 and cathode marked by a bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; marking bar identifies this pin; connects to ground or return path in buck/flyback outputs |
| 2 | Anode (A) | Positive input terminal; ties to switch node or input rail; carries full forward current during conduction |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Improves ruggedness against ESD and transient overvoltage without increasing VF or size |
| Ultra-low VF at 1 A | 420 mV typ. enables >95% efficiency in 5 V–12 V synchronous rectifier replacements |

| AEC-Q101 qualification | Validated for temperature cycling, HTRB, and ESD per automotive reliability standards |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Reverse polarity protection for 12 V supply rail feeding microcontrollers and CAN transceivers. IC Role / Device Role: Unidirectional blocking diode placed in series with input power path. Use Value: 420 mV VF limits voltage drop to <0.5% at 1 A, preserving brown-out margin while rejecting reverse battery connection. | Use Scenario: Output clamp in USB-C PD sink circuit to prevent backfeed during adapter hot-swap events. IC Role / Device Role: Low-capacitance (66–80 pF) Schottky clamp between VBUS and GND. Use Value: Fast turn-on and low IR ensure clamping within 100 ns while adding negligible signal loading to CC lines. |
| Low-Power IoT Sensor Node | Industrial 24 V DC/DC Auxiliary Rail |
Use Scenario: Input rectification for energy-harvesting boost converter powering BLE MCU from piezoelectric source. IC Role / Device Role: High-efficiency rectifier in AC-to-DC stage operating at µA–mA currents. Use Value: VF as low as 150 mV @ 1 mA enables usable output even at sub-100 mV input amplitudes. | Use Scenario: Freewheel diode in isolated flyback auxiliary winding supplying 3.3 V logic for gate drivers. IC Role / Device Role: Secondary-side rectifier handling 1 A peak current at 100 kHz switching frequency. Use Value: Low Cd and 150 K/W Rth(j-sp) minimize switching loss and thermal rise in confined transformer footprints. |
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 NSR20F20NXT5G | Same 20 V/1 A rating; VF = 450 mV typ. @ 1 A; SOD-123 package (not SOD123F) | Slightly higher VF increases conduction loss by ~7%; no AEC-Q101 documentation publicly available | Select if sourcing flexibility is prioritized over automotive qualification and minimal VF |
| Vishay VS-1EQH02-M3/84A | 20 V/1 A; VF = 490 mV typ.; TO-277A package (larger, 3.5 mm × 1.9 mm) | Higher VF and larger footprint reduce suitability for space-constrained automotive modules | Prefer only where legacy TO-277A board compatibility is required |
Compared with NSR20F20NXT5G and VS-1EQH02-M3/84A, PMEG2010EH-QX delivers the lowest VF (420 mV), smallest footprint (SOD123F), and verified AEC-Q101 compliance - making it optimal for next-gen automotive ECUs where thermal density and reliability are critical.

FAQ
What is the maximum allowable junction temperature for PMEG2010EH-QX?
The absolute maximum junction temperature is 150 °C, as specified in Table 5. Operation above this limit risks permanent degradation. Derating is required above 85 °C ambient when operating at full 1 A current, based on Rth(j-a) = 330 K/W for standard FR4 mounting.
Does PMEG2010EH-QX support reflow soldering per JEDEC standards?
Yes - the SOD123F package is qualified for lead-free reflow per JEDEC J-STD-020. Recommended profile includes peak temperature ≤260 °C, time above 217 °C ≤60 seconds, and ramp rate ≤3 °C/s, using the footprint dimensions shown in Figure 6.
How does the guard ring improve reliability in automotive environments?
The integrated guard ring mitigates edge breakdown under high dv/dt and transient overvoltage conditions common in automotive 12 V systems (e.g., load dump). It enhances ESD robustness (HBM ≥2 kV) and improves long-term stability under thermal cycling without compromising forward conduction characteristics.
Is the cathode marking consistent across all production lots?
Yes - the cathode is consistently indicated by a single bar on the top surface of the SOD123F package, aligned with Pin 1 per Table 2 and Figure 5. Marking code "A9" (per Table 4) appears adjacent to the bar and is verified across all released lots.
