Product details
Overview
PMEG3010EH from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage DC-to-DC conversion and reverse polarity protection in space-constrained SMD applications. It delivers 1 A forward current, 30 V reverse voltage rating, and ultra-low 450 mV typical forward voltage at 1 A - enabling high-efficiency power management in portable and battery-powered systems.
For engineers reviewing the PMEG3010EH datasheet, PMEG3010EH pinout, PMEG3010EH application, or PMEG3010EH equivalent, this device is selected for its verified low VF performance, SOD123F thermal profile, cathode-marked polarity reliability, and suitability in compact 5 V/3.3 V rail protection and synchronous rectification stages.
Technical Context
This Schottky diode uses a planar MEGA (Maximum Efficiency General Application) structure with an integrated guard ring to suppress edge breakdown and improve surge robustness under transient reverse stress. Its low junction capacitance (55–70 pF) and fast switching enable use in high-frequency SMPS output stages without significant switching loss penalties.
The device operates with a maximum junction temperature of 150 °C and exhibits thermal resistance of 330 K/W (junction-to-ambient, free air) and 60 K/W (junction-to-solder point), confirming its suitability for thermally demanding PCB layouts where cathode pad copper area is limited.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current (IF) | 1 A continuous - supports full-rated output in 5 V/3.3 V buck converter secondary side |
| Reverse voltage (VR) | 30 V - provides margin above 24 V industrial rails and 12 V automotive systems |
| Forward voltage (VF) | 450 mV typ. @ 1 A - reduces conduction loss by >30% vs. standard Schottkys (e.g., 600+ mV) |
| Reverse current (IR) | 40 µA max @ 30 V - ensures minimal leakage in battery backup and always-on circuits |
| Junction capacitance (Cd) | 55 pF typ. @ 1 V - enables clean switching in >1 MHz DC-DC topologies without ringing |
| Thermal resistance (Rth(j-sp)) | 60 K/W - allows direct thermal coupling to PCB copper for passive cooling in fanless designs |
| Repetitive peak forward current (IFRM) | 7 A @ tp ≤ 1 ms - withstands startup surges and load-dump transients in power supply inputs |
Pinout & Package
Encapsulated in the SOD123F surface-mount plastic package (3.6 mm × 1.7 mm × 1.0 mm), PMEG3010EH features a two-terminal configuration with cathode marked by a bar on the body. The package supports reflow soldering only and is optimized for thermal dissipation via the cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode | Connected to output rail or ground return path; carries full forward current and dissipates majority of heat |
| 2 | Anode | Connected to input source or switching node; polarity-sensitive - reverse connection causes immediate conduction failure |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents edge breakdown under high dv/dt or mechanical stress - improves long-term reliability in vibration-prone environments |
| Ultra-low VF (450 mV typ.) | Reduces power loss to <450 mW at 1 A - critical for extending battery life in wearables and IoT sensors |
| SOD123F footprint | Enables placement in <2.5 mm² board area - ideal for ultra-thin mobile accessories and modular power modules |
| 150 °C max junction temperature | Supports operation in sealed enclosures or high-ambient industrial control cabinets without derating |
Applications
| USB Power Delivery Protection | 5 V Buck Converter Output Rectification |
|---|---|
Use Scenario: Reverse polarity and overvoltage protection on USB-C receptacle inputs in portable chargers and docking stations. IC Role / Device Role / Timing Role: Unidirectional blocking diode placed between connector and system power rail. Use Value: Prevents damage from misinserted cables while adding <0.5 mΩ effective series resistance due to low VF. |
Use Scenario: Secondary-side rectification in 5 V, 1 A synchronous buck converters for FPGA I/O supplies. IC Role / Device Role / Timing Role: Freewheeling path during high-side switch off-time; requires sub-100 ns recovery. Use Value: Enables >94% efficiency at 1 MHz switching with no reverse recovery charge (Qrr = 0). |
| Industrial Sensor Node Power Rail | Li-ion Battery Backup Circuit |
Use Scenario: Isolation between main 24 V supply and 3.3 V microcontroller rail in factory-floor wireless sensors. IC Role / Device Role / Timing Role: Low-leakage isolation diode preventing backfeed during main supply brownout. Use Value: 40 µA max IR at 30 V ensures <1.2 µA standby current drain - extends 10-year battery life targets. |
Use Scenario: OR-ing diode between primary Li-ion cell and backup coin cell in medical wearables. IC Role / Device Role / Timing Role: Automatic power source selection with minimal voltage drop across backup path. Use Value: 450 mV VF adds only 1.5% voltage loss at 100 mA - preserves usable capacity of 3 V CR2032 cells. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (520 mV typ. @ 1 A); larger SOD-123 package (same outline but 0.2 mm taller) | Marginally lower efficiency in thermally constrained layouts; identical pinout | Select when legacy design reuse or higher surge rating (10 A IFSM) is prioritized over minimal VF |
| SS12 | Lower VR (20 V); TO-277 package (larger, 3.5 mm × 2.5 mm); 550 mV VF @ 1 A | Not suitable for 24 V systems; requires more PCB area and manual rework compatibility | Choose only if existing TO-277 footprint must be retained and 20 V rating suffices |
Compared with RB050M-30 and SS12, PMEG3010EH offers the lowest VF in its class and smallest thermal resistance in SOD123F, making it optimal for high-density, high-efficiency 3.3–24 V power paths where board space and thermal headroom are limiting.

FAQ
What is the maximum allowable ambient temperature for continuous 1 A operation?
At 1 A forward current, PMEG3010EH requires ambient temperature ≤55 °C for continuous operation per datasheet limiting values. Above this, derating is mandatory: at 85 °C ambient, maximum IF drops to 0.65 A to maintain Tj ≤150 °C using Rth(j-a) = 330 K/W.
Is PMEG3010EH suitable for reverse battery protection in automotive applications?
Yes - its 30 V VR rating provides 20 % margin above 24 V nominal automotive systems, and the integrated guard ring enhances survivability during load dump transients. However, it is not AEC-Q200 qualified; for certified automotive use, Nexperia's PMPB20XN series is recommended.
Can PMEG3010EH replace a standard PN-junction diode like 1N4007 in a 5 V supply?
No - while it can block reverse voltage, PMEG3010EH's 30 V VR is insufficient for 1N4007's 1000 V rating, and its 1 A rating matches only light-load scenarios. It is intended for low-VF, high-frequency rectification - not general-purpose AC line rectification.
Does the SOD123F package support wave soldering?
No - Nexperia explicitly states reflow soldering is the only recommended method. Wave soldering is not characterized for PMEG3010EH and risks thermal damage due to its low thermal mass and plastic encapsulation; SOT23 variants in the same family permit wave soldering under strict conditions.
