Product details
Overview
PMEG3010EGW-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 1 A forward current, featuring low 450 mV typical forward voltage and 40 µA typical reverse leakage - deployed in automotive-grade DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3010EGW-QX datasheet, PMEG3010EGW-QX pinout, PMEG3010EGW-QX application, or PMEG3010EGW-QX equivalent, key selection criteria include AEC-Q101 qualification, SOD123 thermal resistance (190 K/W to solder point), junction temperature limit of 150 °C, and cathode-marked anode-cathode polarity configuration.
Technical Context
This Schottky diode uses a planar silicon structure with integrated guard ring to suppress edge breakdown under high dv/dt or mechanical stress, enabling stable operation in automotive transients. Its low VF stems from optimized metal-semiconductor interface and thin epitaxial layer design.
Thermal performance is defined by two critical paths: Rth(j-sp) = 190 K/W (junction-to-solder-point, cathode pad) and Rth(j-a) = 310 K/W (junction-to-ambient, free air), both measured on FR4 PCB with standardized footprint and 1 cm² cathode copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V maximum - defines maximum blocking capability before breakdown in reverse bias; suitable for 24 V automotive rail protection. |
| Forward Current (IF) | 1 A continuous - supports steady-state conduction in low-voltage power rails without derating below 55 °C solder point temperature. |
| Forward Voltage (VF) | 450 mV typical at 1 A - reduces conduction loss by ~55% vs. standard silicon diodes, directly improving DC-DC efficiency. |
| Reverse Leakage (IR) | 40 µA typical at 30 V - enables low standby power in always-on automotive modules such as body control units. |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood environments with ambient up to 125 °C when properly heatsinked via cathode pad. |
| Diode Capacitance (Cd) | 55–70 pF at 1 V - minimizes switching noise and EMI in high-frequency SMPS (>500 kHz) due to low stored charge. |
Pinout & Package
Encapsulated in a compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm), with cathode identified by a marking bar on the device body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to negative output or ground return path; marked side of package; primary thermal path to PCB copper. |
| 2 | Anode (A) | Connected to input or positive rail; carries full forward current; electrically isolated from thermal pad. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive use per stress test requirements including HTGB, HTRB, and temperature cycling - ensures reliability in engine control and ADAS modules. |
| Guard ring integration | Suppresses edge-related avalanche and leakage under mechanical stress or voltage transients - improves long-term stability in vibration-prone environments. |
| Low Rth(j-sp) = 190 K/W | Enables 1 A continuous operation with ≤30 °C junction-to-pad rise on FR4 - eliminates need for oversized copper or thermal vias in space-constrained layouts. |
| 450 mV VF @ 1 A | Reduces power dissipation to 450 mW versus >1 W for comparable Si diodes - lowers thermal load in sealed enclosures and extends lifetime of adjacent components. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |
|---|---|
|
Use Scenario: Reverse polarity protection on 12 V supply rail feeding microcontroller, CAN transceiver, and LED drivers. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage during battery jump-start misconnection. Use Value: 450 mV VF limits voltage drop to <0.5% of rail, preserving brown-out margin for 3.3 V LDOs downstream. |
Use Scenario: Input clamp in USB-C PD sink circuit protecting buck controller from backfeed during hot-plug events. IC Role / Device Role / Timing Role: Fast-recovery Schottky barrier preventing reverse current flow into source port during cable swap. Use Value: 40 µA IR at 30 V ensures <1 µW standby leakage - critical for meeting USB Battery Charging v1.2 quiescent power limits. |
| Industrial 24 V IoT Gateway | Medical Portable Monitor Power Path |
|
Use Scenario: OR-ing diode in dual-input (main + backup battery) 24 V power system for wireless sensor hub. IC Role / Device Role / Timing Role: Low-loss forward conduction path enabling seamless switchover without voltage sag.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay SS13HE3_A/H | 30 V VR, 3 A IF, VF = 500 mV typ., SMC package (larger than SOD123) | Higher current capacity but 3× larger footprint and 2× higher Rth(j-a); unsuitable for ultra-compact automotive modules | Select only if >1 A average current or higher surge immunity (IFSM = 50 A) is required. |
| ON Semiconductor NSR0130P2T5G | 30 V VR, 300 mA IF, VF = 410 mV typ., SOD-123FL package (same outline, thinner profile) | Lower current rating limits use to sub-500 mA loads; thinner package reduces thermal mass and solder joint reliability in thermal cycling | Prefer for space-constrained wearables where 300 mA suffices and height clearance <1.0 mm is mandatory. |
Compared with SS13HE3_A/H and NSR0130P2T5G, PMEG3010EGW-QX uniquely balances 1 A current, 450 mV VF, AEC-Q101 compliance, and minimal SOD123 footprint - making it optimal for automotive ECUs where thermal density, reliability, and board area are co-constrained.

FAQ
Is PMEG3010EGW-QX suitable for synchronous rectification?
No - PMEG3010EGW-QX is a passive Schottky rectifier, not a MOSFET-based synchronous rectifier IC. It lacks gate drive interface, internal control logic, or timing circuitry. Its role is unidirectional conduction only, with fixed anode-cathode polarity and no active switching capability.
What is the meaning of the 'Q' suffix in PMEG3010EGW-QX?
The 'Q' denotes AEC-Q101 qualification per Automotive Electronics Council standards. The 'X' in PMEG3010EGW-QX is a revision or packaging variant identifier used internally by Nexperia for tape-and-reel configuration or moisture sensitivity level (MSL) differentiation - not a functional change from PMEG3010EGW-Q.
Can PMEG3010EGW-QX replace a standard silicon rectifier like 1N4007?
Only in low-voltage, high-efficiency applications ≤30 V and ≤1 A. Unlike the 1N4007 (1000 V, 1 A, VF ≈ 1.1 V), PMEG3010EGW-QX has lower VR rating and no surge capability (IFSM = 9 A vs. 1N4007's 30 A). It must not be used in AC mains rectification or high-voltage flyback snubbers.
Does the SOD123 package support reflow soldering per J-STD-020?
Yes - Nexperia specifies PMEG3010EGW-QX for lead-free reflow per J-STD-020 Class 3 peak temperature (260 °C), with recommended footprint per Figure 8 (sod123_fr): 2.36 mm × 1.11 mm cathode pad, 0.81 mm × 0.91 mm anode pad, and 0.91 mm solder mask opening.
