Product details
Overview
PMEG4010EH from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for low-voltage, high-efficiency power conversion. It delivers 1 A forward current at 40 V reverse voltage, with a typ. 540 mV forward voltage at 1 A and 25 °C, enabling ultra-low conduction loss in compact DC-DC converters.
For engineers reviewing the PMEG4010EH datasheet, PMEG4010EH pinout, PMEG4010EH application, or PMEG4010EH equivalent, key selection criteria include its SOD123F package footprint, 640 mV max VF at full load, 100 µA max IR at 40 V, thermal resistance of 150 K/W (junction-to-solder point), and suitability for reverse polarity protection in space-constrained portable electronics.
Technical Context
This Schottky diode uses a planar die structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability under transient conditions. Its low VF stems from optimized metal-semiconductor interface design, not edge termination alone.
The device operates with junction temperatures up to 150 °C and requires reflow soldering only-no hand-soldering or wave soldering. Thermal performance is specified for FR4 PCB mounting with 1 cm² cathode pad, yielding Rth(j-sp) = 150 K/W and Rth(j-a) = 330 K/W under standard conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 540–640 mV at 1 A, 25 °C: enables <1.2 W conduction loss in 1 A continuous paths, critical for >90% efficiency in buck converters. |
| Reverse Voltage (VR) | 40 V maximum: supports 36 V nominal input rails with 10% margin, suitable for industrial 24 V and automotive 12 V auxiliary supplies. |
| Reverse Current (IR) | 30–100 µA at 40 V, 25 °C: ensures minimal leakage-induced standby power loss in battery-backed systems. |
| Diode Capacitance (Cd) | 43–50 pF at 1 V, 1 MHz: limits switching node ringing and EMI in high-frequency (>500 kHz) SMPS designs. |
| Thermal Resistance (Rth j-sp) | 150 K/W: allows 0.83 W dissipation before reaching 150 °C junction temp when soldered to 1 cm² copper pad-key for thermal-aware layout. |
| Repetitive Peak Forward Current (IFRM) | 7 A (tp ≤ 1 ms, δ ≤ 0.25): supports surge handling in hot-swap or inrush-limited circuits without derating. |
Pinout & Package
Encapsulated in a SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm body), this two-terminal device features a standardized footprint optimized for automated reflow assembly on FR4 PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in forward bias; serves as primary thermal path to PCB copper via exposed cathode tab. |
| 2 (A) | Anode | Connected to lower-potential node during conduction; carries full forward current with minimal parasitic inductance due to short internal bond. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents premature edge breakdown under voltage transients, improving long-term reliability in noisy industrial environments. |
| Very low VF (typ. 540 mV) | Reduces forward conduction loss by ~40% vs. comparable 40 V Schottkys, directly increasing light-load efficiency in always-on subsystems. |
| SOD123F package | Enables 2.6 mm × 1.6 mm board area usage-30% smaller than SMA-without sacrificing thermal performance or solder joint integrity. |
| Non-automotive qualified | Meets industrial-grade reliability standards but excludes AEC-Q200 testing; intended for commercial/industrial applications only. |
Applications
| USB Power Delivery Adapter | Industrial Sensor Node |
|---|---|
|
Use Scenario: Secondary-side synchronous rectification in 20–65 W GaN-based USB PD adapters. IC Role / Device Role / Timing Role: Low-VF freewheeling diode replacing MOSFET gate drive complexity in cost-sensitive designs.

| Point-of-Load DC-DC Converter | Low-Power Display Backlight |
|
Use Scenario: Output rectification in 1.2 V/5 A buck converter powering FPGA core logic. IC Role / Device Role / Timing Role: High-current, low-loss output diode operating at 1 MHz switching frequency. Use Value: Limits conduction loss to 0.54 W at full load, reducing local hotspot temperature rise by 18 °C vs. legacy Schottky alternatives. |
Use Scenario: LED string current steering in monochrome LCD backlight with single-cell Li-ion input. IC Role / Device Role / Timing Role: Isolation diode preventing backfeed from boost converter into battery during sleep mode. Use Value: 30 µA max IR at 4.2 V ensures <1 µA standby drain-extending shelf life beyond 18 months without recharge. |
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 NSS40100U1T6G | Same 40 V VR, 1 A IF rating, but VF = 550–700 mV (typ/max); SOD-123 package (not SOD123F); Rth(j-a) = 360 K/W. | Larger thermal resistance increases junction temp by ~10 °C at same power; less suited for thermally dense layouts. | Select when existing SOD-123 footprint compatibility is required and thermal margin exceeds 15 °C. |
| Vishay VS-1EQH04-M3/5AT | Higher VR = 45 V, VF = 570–690 mV, but IF = 1.1 A; DO-214AC (SMA) package; 5.3 mm × 2.7 mm footprint. | 3× larger board area required; better surge immunity (IFSM = 25 A) but incompatible with miniaturized SOD123F layouts. | Choose for designs needing higher voltage margin or legacy SMA compatibility, accepting size penalty. |
Compared with NSS40100U1T6G and VS-1EQH04-M3/5AT, PMEG4010EH offers the lowest thermal resistance in its class (150 K/W j-sp), smallest footprint (SOD123F), and tightest VF distribution-making it optimal for space- and thermally constrained 1 A rectification where leakage and efficiency are co-critical.

FAQ
Is PMEG4010EH suitable for automotive applications?
No. The datasheet explicitly states this part is non-automotive qualified and lacks AEC-Q200 certification. It is rated for industrial and commercial use only, with junction temperature range −65 °C to 150 °C but no automotive-specific stress testing or PPAP documentation.
What is the recommended soldering method for PMEG4010EH?
Reflow soldering is the only recommended method per Nexperia's datasheet. Hand soldering, wave soldering, or infrared rework are not qualified and may damage the die or compromise the guard ring integrity due to uncontrolled thermal profiles.
How does the integrated guard ring improve reliability?
The guard ring mitigates electric field crowding at the semiconductor edge, raising the effective breakdown voltage under transient overvoltage events. This prevents localized avalanche and degradation during repetitive 40 V reverse-bias surges common in DC-DC converter output stages.
Can PMEG4010EH replace a standard silicon diode in a 5 V, 1 A linear regulator front-end?
Yes-its 540 mV VF reduces dropout voltage by ~700 mV versus a typical 1N4007 (1.1 V), allowing operation down to ~5.5 V input for a 5 V output. However, reverse leakage (up to 100 µA) is higher than silicon, so verify impact on quiescent current in low-power modes.
