Product details
Overview
PMEG1020EH-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 10 V reverse voltage and 2 A forward current, featuring ultra-low forward voltage (350–460 mV at 2 A) in a compact SOD123F surface-mount package. It serves as a low-loss unidirectional power switch in automotive-grade DC/DC converters and polarity protection circuits.
For engineers reviewing the PMEG1020EH-QX datasheet, PMEG1020EH-QX pinout, PMEG1020EH-QX application, or PMEG1020EH-QX equivalent, key selection criteria include its AEC-Q101 qualification, 0.35–0.46 V forward drop at 2 A, 2 mA max reverse leakage at 10 V, thermal resistance of 150 K/W (junction-to-solder point), and SOD123F footprint compatibility with high-density PCB layouts.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown under transient stress, enabling reliable operation in automotive environments. Its low VF stems from optimized metal-semiconductor interface design and thin epitaxial layer control, minimizing conduction loss without sacrificing reverse leakage performance.
The device operates within −65 °C to +150 °C junction temperature range and delivers 7 A repetitive peak forward current (tp ≤ 1 ms) and 9 A non-repetitive surge capability (tp = 8 ms). Thermal performance is specified for two mounting conditions: standard FR4 footprint (Rth(j-a) = 330 K/W) and enhanced cathode pad (Rth(j-sp) = 150 K/W).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 10 V maximum - defines absolute maximum blocking capability in reverse bias; suitable for 5–8 V rail protection and buck converter freewheeling. |
| Forward Current (IF) | 2 A continuous at Tsp ≤ 55 °C - supports sustained load current in compact power stages without forced cooling. |
| Forward Voltage (VF) | 350–460 mV at IF = 2 A - reduces conduction loss by >40% vs. standard silicon diodes, improving efficiency in low-voltage DC/DC stages. |
| Reverse Leakage (IR) | 1.2–3 mA at VR = 10 V, 25 °C - low enough to avoid significant standby power loss in battery-sensitive applications. |
| Diode Capacitance (Cd) | 40–50 pF at VR = 5 V, 1 MHz - enables fast switching with minimal AC coupling in high-frequency SMPS output rectification. |
| Junction Temperature (Tj) | −65 to +150 °C - meets extended automotive ambient requirements and supports operation near engine compartments or under-hood modules. |
Pinout & Package
Encapsulated in the SOD123F plastic surface-mount package (2.6 mm × 1.6 mm × 1.1 mm body), this diode uses a 2-lead configuration with gull-wing leads for reflow soldering on standard FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in reverse-biased blocking mode; carries full forward current during conduction; requires ≥1 cm² copper pad for optimal thermal dissipation (Rth(j-sp) = 150 K/W). |
| 2 (A) | Anode | Connected to lower-potential node; forms the input side of rectification path; electrically isolated from cathode except during forward conduction. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTGB, HTRB, and ESD-HBM ≥ 2 kV - enables deployment in ADAS, body control, and infotainment systems without additional qualification. |
| Ultra-low VF | Typical 350 mV at 2 A - cuts forward power loss to <0.7 W, reducing thermal load in space-constrained modules and extending battery runtime in portable automotive subsystems. |
| Integrated guard ring | Planar structure with edge termination - prevents premature avalanche breakdown at high dv/dt or temperature gradients, improving reliability in noisy vehicle electrical systems. |
| SOD123F footprint | 2.6 mm × 1.6 mm outline with 0.7 mm lead pitch - compatible with high-volume pick-and-place assembly and reflow profiles; occupies ~40% less board area than SMA packages. |
Applications

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 NSR1020HT1G | Same 10 V/2 A rating but VF = 420–520 mV at 2 A; Rth(j-a) = 300 K/W; no AEC-Q101 certification. | Limited to industrial/commercial use; not approved for automotive ECUs or safety-critical modules. | Select when cost sensitivity outweighs automotive qualification and thermal margin is sufficient. |
| Vishay SS12 | 12 V/2 A rating; VF = 500 mV typical at 2 A; SOD-123 package (not SOD123F); Rth(j-a) = 250 K/W. | Higher VR allows margin in 12 V nominal systems but larger VF increases conduction loss by ~150 mW at full load. | Choose if system requires 12 V blocking headroom and layout accommodates slightly longer SOD-123 body (3.7 mm vs. 3.5 mm). |
Compared with NSR1020HT1G and SS12, PMEG1020EH-QX offers the lowest VF in its class, AEC-Q101 compliance, and optimized thermal resistance for solder-point cooling - making it preferred for automotive power rails where efficiency, reliability, and footprint are jointly constrained.

FAQ
Is PMEG1020EH-QX suitable for synchronous rectification?
No - PMEG1020EH-QX is a passive Schottky rectifier, not a synchronous rectifier IC or MOSFET-based solution. It functions as a unidirectional conduction device with fixed forward voltage drop and cannot be actively controlled via gate signal. For synchronous rectification, discrete N-channel MOSFETs with external gate drivers or integrated SR controllers are required.
What is the maximum allowable PCB copper area for cathode pad to achieve Rth(j-sp) = 150 K/W?
The datasheet specifies that Rth(j-sp) = 150 K/W is achieved with a 1 cm² tin-plated copper pad connected to the cathode (Pin 1) on a single-sided FR4 PCB. This pad must be solid, unbroken, and directly attached to the cathode land - split pours, thermal reliefs, or vias reduce effectiveness and increase thermal resistance beyond the rated value.
Does PMEG1020EH-QX have a built-in ESD protection structure?
No dedicated ESD protection circuitry is described in the datasheet. Its AEC-Q101 qualification includes HBM testing to ≥2 kV, which confirms robustness against typical handling ESD, but it lacks explicit on-chip TVS or snapback elements. External ESD protection is recommended if exposed to >8 kV contact discharge per IEC 61000-4-2.
Can PMEG1020EH-QX replace a 1N5819 in existing designs?
Yes - PMEG1020EH-QX matches 1N5819's 10 V/1 A rating (with higher 2 A continuous current), offers significantly lower VF (350–460 mV vs. 450–600 mV), and fits the same SOD123F footprint. However, verify layout thermal relief and ensure the 2 A rating aligns with actual operating current, as derating rules differ between legacy and AEC-Q101 components.
