Product details
Overview
PMEG3010ER,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency DC-to-DC conversion and reverse polarity protection. It delivers 1 A average forward current at ≤30 V reverse voltage, with a typical forward voltage of 320 mV at 1 A and 25 °C, enabling reduced conduction loss in compact power supplies.
For engineers reviewing the PMEG3010ER,115 datasheet, PMEG3010ER,115 pinout, PMEG3010ER,115 application, or PMEG3010ER,115 equivalent, key selection criteria include low VF performance under 1 A load, thermal resistance to solder point (18 K/W), SOD123W package compatibility with reflow/wave soldering, and validated use in SMPS output rectification and battery protection circuits.
Technical Context
This Schottky diode employs clip-bond technology to enhance thermal performance and power capability, supporting continuous operation up to 150 °C junction temperature. Its planar structure with integrated guard ring improves robustness against transient overvoltage and ESD stress without compromising low forward voltage.
The device exhibits low reverse recovery charge (Qrr not specified but inherently near-zero due to Schottky architecture) and capacitance of 170 pF at 1 V reverse bias, making it suitable for high-frequency switching applications where fast turn-off and minimal capacitive loading are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 1 A average forward current - supports continuous 1 A DC or pulsed loads in space-constrained DC/DC outputs |
| VR | 30 V reverse voltage - rated for 24 V system rails with 20 % margin, suitable for industrial and consumer power inputs |
| VF @ 1 A, 25 °C | 320–360 mV - enables <0.36 W conduction loss at full load, reducing thermal burden on PCB |
| IR @ 30 V, 25 °C | 0.6–1.5 mA - low leakage preserves efficiency in standby and battery-backed circuits |
| Rth(j-sp) | 18 K/W - low thermal resistance from junction to cathode solder point enables effective heat transfer via copper pad |
| Cd @ 1 V, 1 MHz | 170 pF - limits high-frequency displacement current and EMI generation in >100 kHz SMPS designs |
Pinout & Package
Encapsulated in the SOD123W (CFP3) surface-mount plastic package - 2.6 mm × 1.7 mm × 1.0 mm body with flat leads optimized for automated assembly and thermal pad attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (marked side) | Cathode (K) | Connected to output/load return path; marking bar identifies this terminal; serves as primary thermal interface via soldered tab |
| 2 | Anode (A) | Connected to input/high-side node; carries forward current into load; minimal thermal contribution compared to cathode |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ruggedness against voltage transients and localized ESD without increasing VF or leakage |
| Clip-bond construction | Improves thermal conductivity and current-carrying capacity versus wire-bonded equivalents in same footprint |
| SOD123W package | Enables 0.1 mm stencil-compatible reflow and wave soldering; supports high-density layout with minimal board area |
| Low VF across temperature range | 320 mV at 25 °C rising only to ~360 mV at 125 °C - maintains efficiency stability over operating range |
Applications
| DC/DC Converter Output Rectification | Battery Reverse Polarity Protection |
|---|---|
|
Use Scenario: Used in synchronous or asynchronous buck converter outputs delivering 3.3 V or 5 V at up to 1 A. IC Role / Device Role: Freewheeling/continuation diode during high-side switch off-time; conducts inductor current to maintain regulation. Use Value: 320 mV VF minimizes conduction loss, improving efficiency by ~0.5 % vs. higher-VF alternatives at 1 A load. |
Use Scenario: Placed in series with battery input to prevent damage when Li-ion or alkaline cells are inserted backward. IC Role / Device Role: Unidirectional current gate - blocks reverse current while allowing normal forward charging/discharging. Use Value: 1.5 mA max IR at 30 V ensures <1 µA standby drain in always-on systems, extending shelf life. |
| USB Power Input Protection | Low-Power IoT Node Power Path |
|
Use Scenario: Integrated into USB-C or micro-USB input stage to isolate host from peripheral power faults. IC Role / Device Role: Input polarity clamp - prevents reverse current flow from peripheral back into host port during hot-plug events. Use Value: SOD123W footprint fits tight USB connector keep-out zones; 18 K/W Rth(j-sp) allows direct thermal coupling to ground plane. |
Use Scenario: Powers ultra-low-power sensors (e.g., BLE MCU + environmental sensor) from coin cell or energy harvester. IC Role / Device Role: Isolation diode between energy source and regulated rail - prevents backfeed and enables seamless source switchover. Use Value: 230 mV VF at 0.1 A enables >95 % voltage retention at microamp-level loads, preserving wake-up responsiveness. |
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 NSS1C200LT1G | 30 V VR, 200 mA IF(AV), SOD-123 package - lower current rating, smaller die | Not suitable for 1 A DC loads; limited to signal-level or low-current bias paths | Select only if board space is tighter and load current remains below 200 mA |
| Vishay VS-1EQH03-M3/84A | 30 V VR, 1 A IF(AV), VF = 450 mV typ @ 1 A - higher forward voltage, TO-277 package | Larger footprint and higher conduction loss; better surge handling (IFSM = 60 A) | Prefer for high-surge environments where VF penalty is acceptable and thermal mass matters more than size |
Compared with NSS1C200LT1G and VS-1EQH03-M3/84A, PMEG3010ER,115 uniquely balances 1 A capability, 320 mV VF, and SOD123W miniaturization - making it optimal for space-constrained, efficiency-critical 24 V-input DC/DC and battery protection where thermal pad access is available.

FAQ
What is the maximum junction temperature for continuous operation?
The PMEG3010ER,115 has a maximum junction temperature (Tj) rating of 150 °C. Continuous operation at this limit requires proper thermal design - including adequate copper area on the cathode pad and ambient temperature control - as confirmed by thermal characterization data showing derated IF(AV) above 100 °C ambient.
Is the SOD123W package compatible with standard reflow profiles?
Yes - Nexperia specifies compatibility with both leaded and lead-free reflow soldering per JEDEC J-STD-020. The CFP3 (SOD123W) package uses tin-plated flat leads and withstands peak temperatures up to 260 °C for ≤30 seconds, matching IPC-A-610 Class 2/3 requirements.
Does this Schottky diode require a heatsink in 1 A applications?
No external heatsink is required. With Rth(j-sp) = 18 K/W and Ptot = 1.8 W at Tamb ≤ 25 °C, a 1 cm² cathode copper pad on FR4 provides sufficient thermal relief for 1 A DC operation at ≤60 °C ambient - verified in Figure 10 of the datasheet.
How does the guard ring affect reliability in real-world use?
The integrated guard ring mitigates edge breakdown under high dv/dt or transient overvoltage conditions - demonstrated by improved UIS (unclamped inductive switching) robustness and ESD tolerance (HBM ≥ 8 kV). It does not alter VF or IR but extends operational lifetime in noisy industrial or automotive-adjacent environments.
