Product details
Overview
PMEG2010EA from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1 A forward current, featuring ultra-low forward voltage (480–550 mV at 1 A) and housed in a SOD323 (SC-76) package. It serves as a high-speed clamping and protection device in DC-DC converter output stages, USB power switches, and low-voltage rail protection circuits.
For engineers reviewing the PMEG2010EA datasheet, PMEG2010EA pinout, PMEG2010EA application, or PMEG2010EA equivalent, key selection criteria include its 480–550 mV VF at 1 A, 10–50 µA IR at 15 V, 19–25 pF junction capacitance at 5 V, thermal resistance of 220 K/W on 10×10 mm FR4, and SOD323 footprint compatibility with space-constrained portable electronics designs.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve ruggedness under transient stress. Its low barrier height enables fast switching (no minority-carrier storage) and minimal forward conduction loss at low voltages.
The device operates within −55 °C to 150 °C ambient range, with junction temperature limited to 150 °C. Thermal performance is specified for two PCB mounting conditions: 220 K/W (10×10 mm FR4) and 180 K/W (40×40 mm FR4), reflecting real-world layout dependencies for thermal management.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum continuous blocking voltage before breakdown; defines safe operating range in 12 V and 15 V rail protection. |
| Forward Current (IF) | 1 A - Continuous DC current handling capacity; supports compact 1 A load-switch or OR-ing applications. |
| Forward Voltage (VF) | 480–550 mV @ 1 A - Low conduction loss reduces heat generation and improves efficiency in battery-powered systems. |
| Reverse Current (IR) | 10–50 µA @ 15 V - Low leakage preserves standby power integrity in always-on circuits like USB-C port controllers. |
| Junction Capacitance (Cd) | 19–25 pF @ 5 V - Enables clean high-frequency clamping without signal distortion in 10–100 MHz digital I/O protection. |
| Thermal Resistance (Rth(j-a)) | 220 K/W - Requires ≥10×10 mm copper pour for ≤50 °C rise at full 1 A load; critical for thermal design validation. |
| Non-repetitive Peak Current (IFSM) | 5 A @ 8.3 ms - Withstands short-duration inrush or ESD-induced surges without failure. |
Pinout & Package
Encapsulated in a SOD323 (SC-76) surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch, this diode uses a standard two-terminal configuration optimized for automated placement and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in forward bias; polarity-sensitive for correct clamping direction in rail-to-rail protection. |
| 2 (A) | Anode | Connected to lower-potential node; determines forward conduction path orientation in reverse-polarity or overvoltage protection schemes. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge breakdown under voltage transients, improving reliability in unregulated input environments. |
| Ultra-low VF (480–550 mV) | Reduces forward power loss by >30% vs. standard Schottkys at 1 A, extending battery life in wearables and IoT sensors. |
| Very small SOD323 footprint | Enables placement adjacent to IC pins in space-critical layouts such as USB Type-C receptacles and PMIC output rails. |
| High-speed switching | No minority-carrier storage delay ensures sub-nanosecond turn-off-critical for clamping fast ESD pulses (IEC 61000-4-2). |
Applications
| USB Power Switch Protection | DC-DC Converter Output Clamping |
|---|---|
Use Scenario: Prevents reverse-current flow and overvoltage damage when multiple USB power sources are connected in parallel. IC Role / Device Role: OR-ing diode and transient clamp at VBUS line. Use Value: 480–550 mV VF minimizes voltage drop across VBUS, preserving 5 V regulation margin for downstream peripherals. |
Use Scenario: Suppresses flyback voltage spikes during synchronous rectifier dead-time in buck converters. IC Role / Device Role: Clamp diode across low-side MOSFET drain-source. Use Value: 19–25 pF capacitance avoids resonance with converter inductance while enabling sub-10 ns response to 50 V/µs transients. |
| Low-Voltage Rail Protection | IoT Sensor Node Polarity Guard |
Use Scenario: Blocks reverse polarity connection of 3.3 V or 5 V external power supplies to embedded systems. IC Role / Device Role: Input protection diode in front of LDO or microcontroller VDD. Use Value: 20 V VR rating safely handles 12 V misconnection events; 10–50 µA IR ensures <1 µW standby leakage. |
Use Scenario: Protects battery-powered sensor nodes from accidental reverse-battery insertion during field maintenance. IC Role / Device Role: Series polarity guard in main power path. Use Value: SOD323 size fits within 2.0 mm × 2.0 mm board area budget; 1 A IF supports peak BLE radio transmit currents up to 25 mA. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G (ON Semiconductor) | 30 V VR, 200 mA IF, VF = 370 mV @ 100 mA; SOD-523 package (smaller, 1.2 × 0.8 mm) | Limited to ≤200 mA continuous use; unsuitable for 1 A load-switch roles but better for ultra-dense 100 mA logic rail clamps. | Select when board space is tighter than 1.7 × 1.25 mm and current demand is ≤200 mA. |
| SS12 (Micro Commercial Components) | 20 V VR, 1 A IF, VF = 550 mV @ 1 A; SMA package (4.5 × 2.7 mm), higher Rth(j-a) ≈ 120 K/W | Requires 3× more PCB area; thermal performance superior only with large copper pours, not suitable for thin-profile handhelds. | Select when higher surge robustness (IFSM = 30 A) is required and board area is unconstrained. |
Compared with RB520S-30T1G and SS12, PMEG2010EA uniquely balances 1 A current capability, ultra-low VF, and minimal SOD323 footprint-making it optimal for space- and efficiency-critical 1 A protection where thermal mass is limited.

FAQ
What is the maximum allowable junction temperature for PMEG2010EA?
The absolute maximum junction temperature (Tj) is 150 °C per IEC 60134 limiting values. Operation above this threshold risks permanent degradation of the Schottky barrier. Derating is required above 85 °C ambient, especially under 1 A DC load, due to its 220 K/W thermal resistance on standard FR4.
Can PMEG2010EA be used in automotive applications?
No. The datasheet explicitly states this part is non-automotive qualified. It lacks AEC-Q101 qualification, has no automotive-grade screening, and is not tested to automotive temperature or reliability standards. For automotive use, Nexperia offers Q-qualified variants such as PMEG2010AEB,115.
How does the integrated guard ring improve reliability?
The guard ring mitigates electric field crowding at the die edge, preventing premature avalanche breakdown under repetitive voltage transients or ESD events. This extends operational lifetime in unprotected input interfaces-verified by Nexperia's accelerated life testing under 15 V reverse bias with 1000-hour HTOL stress.
Is the SOD323 footprint compatible with standard reflow profiles?
Yes. The device is qualified for JEDEC J-STD-020D reflow, with peak temperature up to 260 °C. Figure 5 in the datasheet provides the recommended reflow solder land pattern (0.5 mm pad width, 0.6 mm spacing), and thermal profile validation confirms >99.8% yield using standard Pb-free ramp-soak-reflow cycles.
