Product details
Overview
PMEG3010EGW-QJ 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, housed in an AEC-Q101-qualified SOD123 package for automotive-grade low-voltage rectification.
For engineers reviewing the PMEG3010EGW-QJ datasheet, PMEG3010EGW-QJ pinout, PMEG3010EGW-QJ application, or PMEG3010EGW-QJ equivalent, key selection criteria include VF vs. IF performance at 25 °C and 150 °C, thermal resistance to solder point (190 K/W), reverse leakage stability under pulsed 30 V bias, and SOD123 footprint compatibility in space-constrained DC/DC and polarity protection circuits.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve surge robustness under repetitive 7 A peak forward current and 9 A non-repetitive surges. Its low VF stems from optimized metal-semiconductor interface design rather than barrier height reduction alone.
Thermal performance is defined relative to two mounting conditions: Rth(j-sp) = 190 K/W on FR4 with 1 cm² cathode pad (critical for automotive thermal cycling reliability), and Rth(j-a) = 310 K/W in free air - both measured using pulsed test methods to avoid self-heating artifacts.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V maximum - defines maximum blocking capability in reverse-biased operation without breakdown. |
| Forward Current (IF) | 1 A continuous - sustainable DC current at ≤55 °C solder point temperature. |
| Forward Voltage (VF) | 450 mV typ. at 1 A, 25 °C - enables high-efficiency rectification with <0.45 W conduction loss. |
| Reverse Current (IR) | 40 µA typ. at 30 V, 25 °C - ensures minimal leakage power in standby or reverse-polarity protection mode. |
| Diode Capacitance (Cd) | 55–70 pF at 1 V, 1 MHz - supports fast switching in SMPS with predictable turn-off behavior. |
| Junction Temperature (Tj) | 150 °C max - enables operation in under-hood automotive environments with derated current above 85 °C. |
| Thermal Resistance (Rth(j-sp)) | 190 K/W - quantifies heat transfer efficiency from junction to cathode solder point on standard FR4 PCB. |
Pinout & Package
Encapsulated in a compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode marked by a bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connects to load ground or return path; marked by bar on package. |
| 2 | Anode (A) | Positive input terminal; accepts input voltage source or switched node in buck/flyback topologies. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under high dv/dt or mechanical stress, improving long-term reliability in automotive transients. |
| AEC-Q101 qualification | Validated for automotive use per stress-test requirements including HTRB, HTGB, and ESD-HBM ≥2 kV. |
| Low thermal resistance to solder point | 190 K/W enables higher sustained current in thermally constrained layouts without heatsinking. |
| Small SOD123 footprint | Reduces PCB area by >40% vs. SMA packages while maintaining 1 A rating - ideal for dense DC/DC modules. |
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 in door modules. IC Role / Device Role: Unidirectional current gate preventing damage during battery jump-start misconnection. Use Value: 450 mV VF minimizes voltage drop across protection diode, preserving >11.5 V at MCU input under 1 A load. | Use Scenario: Input clamp in USB-C PD sink circuit limiting reverse current from VBUS to auxiliary rails. IC Role / Device Role: Low-leakage blocking diode isolating secondary power domains during hot-plug events. Use Value: 40 µA IR at 30 V ensures <1.2 µW standby leakage, critical for battery-backed USB-C accessories. |
| Industrial 24 V DC/DC Converter | Low-Power IoT Sensor Node |
Use Scenario: Output rectification in synchronous buck converter delivering 3.3 V @ 800 mA to FPGA I/O banks. IC Role / Device Role: Freewheeling diode complementing high-side MOSFET in non-synchronous mode or catch diode in pseudo-synchronous designs. Use Value: 55–70 pF capacitance limits ringing during turn-off, reducing EMI in noise-sensitive industrial control systems. | Use Scenario: Supply isolation between coin-cell backup and main Li-ion rail in wireless sensor transceivers. IC Role / Device Role: Leakage-suppressing barrier preventing main battery discharge through backup circuitry. Use Value: 150 µA max IR at 30 V ensures <4.5 µA worst-case leakage into 3 V backup domain - extending shelf life beyond 10 years. |
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 NSS10100HT1G | Same SOD123 package, 30 V VR, but VF = 500 mV min at 1 A - 50 mV higher typical drop. | Higher conduction loss reduces efficiency in thermally limited 1 A DC/DC outputs. | Select when legacy ON Semi BOM alignment is required and 50 mV VF penalty is acceptable. |
| Vishay SS13HE3/5BT | SMA package (larger), 30 V VR, VF = 450 mV typ., but not AEC-Q101 qualified. | Lacks automotive stress qualification - unsuitable for under-hood or safety-critical modules. | Choose only for cost-sensitive industrial or consumer applications where qualification is not mandated. |
Compared with NSS10100HT1G and SS13HE3/5BT, PMEG3010EGW-QJ delivers identical VF performance with guaranteed automotive qualification and superior thermal resistance to solder point - making it optimal for space- and reliability-constrained automotive power rails.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C. Continuous operation at this limit requires strict thermal design: average forward current must be derated to ≤0.5 A at Tsp = 135 °C, and PCB layout must provide ≥1 cm² copper pad on cathode side to maintain Rth(j-sp) ≤190 K/W.
Is PMEG3010EGW-QJ compatible with lead-free reflow soldering profiles?
Yes - it is qualified for standard JEDEC J-STD-020D Level 1 reflow, with peak temperature up to 260 °C for ≤30 seconds. The SOD123 package uses matte tin termination and passes thermal shock testing per AEC-Q101, ensuring interconnect integrity after multiple reflow cycles.
How does the guard ring affect surge performance compared to non-guarded Schottkys?
The integrated guard ring suppresses electric field crowding at the die edge, enabling 9 A non-repetitive peak forward surge (IFSM) and 7 A repetitive surge (IFRM) - exceeding typical unguarded SOD123 Schottkys by ≥20%. This directly improves survivability during load dump or inductive kick events in automotive 12 V systems.
Can this diode replace a standard PN junction rectifier in a 5 V, 1 A linear regulator output?
No - it is not rated for linear regulator output protection due to lack of safe operating area (SOA) characterization under continuous reverse-biased avalanche conditions. Its 30 V VR rating applies only to blocking mode, not to sustained reverse conduction; use only in forward-biased rectification or polarity protection roles.
