Product details
Overview
PMEG3010EGWX 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 SOD123 surface-mount package for space-constrained DC-to-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG3010EGWX datasheet, PMEG3010EGWX pinout, PMEG3010EGWX application, or PMEG3010EGWX equivalent, key selection criteria include VF vs. IF trade-off at 25 °C and 150 °C, thermal resistance to solder point (190 K/W), junction temperature limit (150 °C), and SOD123 footprint compatibility with FR4 PCB layouts.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve surge robustness under transient reverse bias. Its low VF stems from optimized metal–semiconductor interface design, enabling high conduction efficiency at low voltages.
Thermal performance is defined by two distinct Rth paths: 310 K/W (junction-to-ambient, free air) and 190 K/W (junction-to-solder point on 1 cm² cathode pad), reflecting its dependency on PCB copper layout for power dissipation management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V maximum - sets upper limit for blocking capability in low-voltage DC rails and flyback snubbers. |
| Forward Current (IF) | 1 A continuous - supports steady-state operation in 5 V/3.3 V buck converter outputs and USB-powered systems. |
| Forward Voltage (VF) | 450 mV typ. at 1 A - reduces conduction loss by ~55% vs. standard PN diodes, critical for >90% efficiency targets. |
| Reverse Leakage (IR) | 40 µA typ. at 30 V - enables low quiescent current in battery backup and always-on monitoring circuits. |
| Junction Temperature (Tj) | 150 °C max - defines safe operating envelope when derated per thermal resistance and ambient conditions. |
| Diode Capacitance (Cd) | 55–70 pF at 1 V - impacts switching speed and EMI in high-frequency SMPS (>500 kHz) and synchronous rectifier gate drive paths. |
Pinout & Package
Encapsulated in a compact SOD123 plastic surface-mount 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) | Output terminal for forward conduction; connects to load side in rectification or to ground in reverse polarity protection. |
| 2 | Anode (A) | Input terminal for forward conduction; connects to source side in rectification or to input rail in polarity protection. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents premature edge breakdown under high dv/dt or mechanical stress, improving reliability in industrial power supplies. |
| Low thermal resistance to solder point | 190 K/W enables 660 mW total power dissipation on standard FR4 with 1 cm² cathode pad-critical for thermally constrained designs. |
| Pulsed peak forward current rating | 9 A non-repetitive (8 ms) supports inrush current handling in hot-swap and capacitor-charging applications. |
| Low capacitance at 1 V reverse bias | 55–70 pF minimizes switching losses and ringing in high-frequency DC/DC converters operating above 1 MHz. |
Applications
| USB Power Delivery Input Stage | Point-of-Load DC/DC Converter Output |
|---|---|
|
Use Scenario: Prevents reverse current flow from downstream 5 V/9 V/15 V rails back into upstream PD controller during fault or disconnect events. IC Role / Device Role / Timing Role: Reverse polarity protection diode placed between PD port and system power domain. Use Value: 450 mV VF limits voltage drop to <1% of 5 V rail, preserving regulation margin while blocking >30 V faults. |
Use Scenario: Freewheeling path in synchronous buck converter output stage where low conduction loss directly improves efficiency. IC Role / Device Role / Timing Role: Low-VF Schottky clamp replacing MOSFET body diode during dead-time intervals. Use Value: 40 µA IR at 12 V ensures <0.5 µW standby loss, supporting Energy Star Level VI and EU CoC Tier 2 requirements. |
| Industrial Sensor Node Power Rail | Low-Power IoT Battery Backup Circuit |
|
Use Scenario: Isolates primary 3.3 V supply from auxiliary 3.3 V sensor bus to prevent cross-talk and backfeed during partial failure. IC Role / Device Role / Timing Role: Bidirectional isolation element in dual-rail sensor subsystems with shared ground. Use Value: SOD123 footprint (2.675 mm × 1.6 mm) fits within 4 mm² board area budget for compact node modules. |
Use Scenario: Blocks main supply from draining coin-cell backup during sleep mode while allowing backup to power RTC and SRAM. IC Role / Device Role / Timing Role: Low-leakage blocking diode in dual-source power path selector. Use Value: 40 µA IR at 3 V extends CR2032 shelf life by >18 months versus standard 1N5819 alternatives. |
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 NSS1C200MT1G | Same 30 V/1 A rating but higher 550 mV VF typ. and 100 µA IR typ.; SOD-123 package. | Higher conduction loss reduces efficiency in high-duty-cycle DC/DC; acceptable for intermittent-use protection. | Select when cost sensitivity outweighs 100 mV VF penalty and thermal margin is ample. |
| Vishay SS12 | 30 V/2 A rating, 500 mV VF typ., 50 µA IR typ.; larger SMA package (4.5 mm × 2.7 mm). | Larger footprint increases board area by 2.7×; higher IF(AV) supports higher average loads. | Choose only if 2 A headroom or legacy SMA footprint compatibility is required over size constraints. |
Compared with NSS1C200MT1G and SS12, PMEG3010EGWX delivers the lowest forward voltage (450 mV) and smallest footprint (SOD123), making it optimal for ultra-compact, high-efficiency 1 A rectification where thermal resistance to solder point (190 K/W) and low leakage (40 µA) are prioritized.

FAQ
What is the maximum allowable junction temperature for PMEG3010EGWX?
The absolute maximum junction temperature is 150 °C, as specified in the limiting values table. Operation above this temperature risks permanent degradation of the Schottky barrier and accelerated reverse leakage. Derating curves in the datasheet require thermal resistance verification based on actual PCB copper area and airflow conditions.
Can PMEG3010EGWX be used in automotive applications?
No-PMEG3010EGWX is explicitly designated as non-automotive qualified in the revision history. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia offers Q-qualified variants such as PMEG3010ERX (with -Q suffix) that meet AEC-Q101 requirements.
How does the guard ring affect surge performance?
The integrated guard ring redistributes electric field lines at the silicon periphery, suppressing edge-initiated avalanche and increasing repetitive peak forward current (IFRM) to 7 A and non-repetitive peak (IFSM) to 9 A-enabling reliable operation during inductive load switching and hot-plug transients without catastrophic failure.
Is the SOD123 footprint compatible with reflow soldering per J-STD-020?
Yes-the device is qualified for standard lead-free reflow profiles per J-STD-020, with peak temperature up to 260 °C. The recommended footprint (Fig. 8) specifies 0.81 mm pad width, 2.36 mm length, and 1.11 mm spacing, matching IPC-7351B SOD123A land pattern for optimal wetting and void control.
