Product details
Overview
PMEG3010ET from Nexperia is a single-channel planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage DC-to-DC conversion and reverse polarity protection circuits. It delivers 1 A forward current at ≤30 V reverse voltage, features a very low 450–560 mV forward voltage at 1 A, and uses the SOT23 (TO-236AB) surface-mount package.
For engineers reviewing the PMEG3010ET datasheet, PMEG3010ET pinout, PMEG3010ET application, or PMEG3010ET equivalent, key selection criteria include its 3-pin SOT23 configuration with NC terminal, thermal resistance of 440 K/W (junction-to-ambient), and low 55–70 pF diode capacitance at 1 V - critical for high-frequency switching efficiency and compact power rail protection.
Technical Context
This Schottky rectifier employs a planar MEGA (Maximum Efficiency General Application) structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability in transient-prone environments. Its low VF enables reduced conduction losses in battery-powered and energy-sensitive systems.
The device operates with a maximum junction temperature of 150 °C and exhibits reverse leakage of only 12–30 µA at 10 V and 40–150 µA at 30 V, supporting stable performance across industrial ambient ranges (−65 °C to +150 °C). Its 5 A repetitive peak forward current rating supports pulsed operation in SMPS flyback and synchronous rectification topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward current (IF) | 1 A continuous at Tsp ≤55 °C - supports sustained output rectification in compact DC/DC converters |
| Reverse voltage (VR) | 30 V maximum - suitable for 24 V nominal input rails with safety margin |
| Forward voltage (VF) | 450–560 mV at IF = 1000 mA - minimizes power loss and thermal rise in high-current paths |
| Reverse current (IR) | 12–30 µA at VR = 10 V - ensures low standby leakage in always-on power domains |
| Diode capacitance (Cd) | 55–70 pF at VR = 1 V, f = 1 MHz - enables fast switching with minimal ringing in >1 MHz converters |
| Thermal resistance (Rth(j-a)) | 440 K/W in free air - defines derating curve for PCB layout with standard SOT23 footprint |
| Repetitive peak forward current (IFRM) | 5 A at tp ≤1 ms, δ ≤0.25 - supports short-duration surge handling in load-dump or startup events |
Pinout & Package
Encapsulated in the SOT23 (TO-236AB) plastic surface-mount package - 3-lead, 1.9 mm × 1.1 mm × 0.9 mm body with gull-wing leads. The marking bar on the package indicates the cathode.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Main current entry point; connects to input/source side of rectification path |
| 2 | No connection (n.c.) | Internally unconnected; must remain floating - no routing or grounding allowed |
| 3 | Cathode | Main current exit point; connects to output/load side and serves as thermal reference node |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ESD and transient robustness without external clamping components |
| Very low forward voltage | Reduces conduction loss by ≥30 % vs. standard silicon diodes at 1 A, improving system efficiency |
| SOT23 3-pin configuration | Enables compact layout while isolating unused terminal to prevent accidental shorts |
| Low diode capacitance | Minimizes switching losses and EMI in high-frequency (>500 kHz) buck and boost converters |
| 150 °C max junction temperature | Supports operation in sealed enclosures or high-ambient industrial environments |
Applications
| USB Power Delivery Protection | Point-of-Load DC/DC Converter |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-30T1G | 2-pin SOD-523, 30 V/200 mA, VF = 370 mV @ 100 mA - lower current rating, smaller package | Limited to sub-500 mA loads; unsuitable for 1 A continuous use | Select when board space is critical and load current stays below 200 mA |
| SS12 | 2-pin SMA, 20 V/1 A, VF = 500 mV @ 1 A - higher VF, larger footprint, no guard ring | Higher conduction loss and lower transient immunity than PMEG3010ET | Choose only if SOT23 is unavailable and thermal margin allows 50 mV VF penalty |
Compared with RB520S-30T1G and SS12, the PMEG3010ET uniquely combines 1 A rating, SOT23 footprint, guard ring protection, and sub-560 mV VF - making it optimal for space-constrained, high-reliability 24 V-input DC/DC stages where both efficiency and ruggedness are required.

FAQ
What is the function of Pin 2 (n.c.) on the PMEG3010ET?
Pin 2 is internally not connected and must remain electrically floating in the PCB layout. It is not a thermal pad or auxiliary terminal - routing traces to or grounding this pin may cause manufacturing defects or unpredictable behavior. The SOT23 package uses this pin position solely for mechanical symmetry and alignment during pick-and-place.
Can PMEG3010ET replace a standard silicon diode in a 24 V SMPS output stage?
Yes - with qualification. Its 30 V VR rating provides margin above 24 V nominal rails, and its 450 mV VF cuts conduction loss by ~65 % versus a 1N4007 (1.1 V). However, verify reverse leakage (up to 150 µA at 30 V) does not impact light-load regulation, and confirm thermal design accommodates 440 K/W Rth(j-a) under actual airflow conditions.
Does the guard ring affect soldering or reflow profile requirements?
No - the guard ring is a monolithic silicon feature and imposes no special soldering constraints. Reflow soldering remains the only recommended process, using the JEDEC-standard profile for SnPb or lead-free paste. The SOT23 footprint dimensions and thermal mass align with standard reflow oven settings; no preheat or cooling ramp adjustments are needed due to the guard ring.
How does PMEG3010ET's 5 A IFRM rating translate to real-world pulse handling?
The 5 A repetitive peak rating applies to square-wave pulses ≤1 ms duration with duty cycle ≤25 %. In practice, this supports brief inrush currents during hot-plug events or capacitor charging surges in USB-C PD adapters. It is not rated for sustained 5 A operation - continuous current remains limited to 1 A at Tsp ≤55 °C per datasheet limiting values.
