Product details
Overview
PMEG4010BEA from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated for 40 V reverse voltage and 1 A forward current, featuring a typical forward voltage of 540 mV at 1 A and 25 °C. It is housed in an ultra-compact SOD323 (SC-76) surface-mount package and is optimized for low-voltage, high-efficiency DC-to-DC conversion in space-constrained portable electronics.
For engineers reviewing the PMEG4010BEA datasheet, PMEG4010BEA pinout, PMEG4010BEA application, or PMEG4010BEA equivalent, key selection criteria include its low VF performance at 1 A, thermal resistance to solder point (90 K/W), diode capacitance (43–50 pF), and suitability for blocking, clamping, and low-power rectification where minimal conduction loss is critical.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability under transient conditions. Its low forward voltage stems from optimized metal-semiconductor junction design, enabling reduced conduction losses in battery-powered and energy-sensitive circuits.
The device operates with a maximum junction temperature of 150 °C and exhibits pulsed peak forward current capability up to 10 A (8 ms square wave), supporting surge-tolerant operation in protection and clamping roles. Thermal resistance from junction to solder point is specified at 90 K/W under defined PCB mounting conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum continuous blocking voltage before breakdown; defines usable input range in DC/DC converters and clamp circuits. |
| Forward Current (IF) | 1 A - Continuous DC current rating at ≤55 °C solder point temperature; sets steady-state power delivery capacity. |
| Forward Voltage (VF) | 540–640 mV @ 1 A, 25 °C - Directly determines conduction loss (0.54–0.64 W at 1 A); enables >90% efficiency in low-VIN buck stages. |
| Reverse Current (IR) | 30–100 µA @ 40 V - Leakage level affecting standby power in always-on systems; low enough for battery-critical applications. |
| Diode Capacitance (Cd) | 43–50 pF @ 1 V, 1 MHz - Limits high-frequency switching noise and affects EMI in fast-switching SMPS feedback paths. |
| Thermal Resistance (Rth(j-sp)) | 90 K/W - Junction-to-solder-point value under specified 1 cm² cathode pad; enables accurate thermal modeling on FR4 PCBs. |
| Junction Temperature (Tj) | 150 °C max - Absolute maximum operating limit; constrains derating curves and long-term reliability in sealed enclosures. |
Pinout & Package
Encapsulated in the SOD323 (SC-76) plastic surface-mount package measuring 1.7 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch, the PMEG4010BEA features a two-terminal configuration optimized for automated placement and reflow soldering on dense PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for forward conduction; connects to load or ground side in rectifier/clamp configurations; thermal path to PCB via exposed cathode pad. |
| 2 | Anode (A) | Input terminal for forward conduction; ties to source or positive rail; polarity-sensitive connection critical for correct rectification direction. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Enhances ESD and transient overvoltage immunity without external components; improves field reliability in unregulated input environments. |
| Very low VF (540 mV typ.) | Reduces forward power loss by ~30% vs. standard Schottkys at 1 A; extends battery runtime in wearables and IoT sensors. |
| SOD323 footprint | 1.7 mm × 1.25 mm body enables placement in <2 mm² board area; supports miniaturized USB-C PD, BLE modules, and hearing aid PCBs. |
| Low leakage (30 µA typ.) | Minimizes quiescent current in always-on protection circuits; maintains system sleep current below 1 µA when paired with low-IQ controllers. |
Applications
| USB Power Delivery Clamp | Wireless Sensor Node Rectifier |
|---|---|
Use Scenario: Clamps transient overvoltage on USB-C VBUS line during hot-plug events or ESD strikes. IC Role / Device Role: Unidirectional voltage clamp placed between VBUS and GND, conducting only during overvoltage excursions. Use Value: 40 V VR rating matches USB PD 3.0 max bus voltage; 10 A non-repetitive surge rating absorbs IEC 61000-4-2 ESD pulses without failure. |
Use Scenario: Rectifies AC output from miniature piezoelectric or RF energy harvesters to charge micro-supercapacitors. IC Role / Device Role: Low-loss AC-to-DC converter front-end in sub-100 µW ambient energy harvesting systems. Use Value: 540 mV VF enables start-up at <200 mV input; 43 pF Cd minimizes capacitive shunting of high-impedance harvester sources. |
| Li-ion Battery Protection Diode | Low-Power MCU Power Rail Blocker |
Use Scenario: Blocks reverse current from parallel Li-ion cells during partial discharge or cell mismatch. IC Role / Device Role: Reverse-battery protection diode in multi-cell battery packs for medical monitors and portable diagnostics. Use Value: 1 A IF rating supports 500 mA charging paths; 30 µA IR prevents measurable self-discharge over 6-month shelf life. |
Use Scenario: Isolates backup power rail (coin cell) from main 3.3 V MCU supply during brown-out or firmware reset sequences. IC Role / Device Role: Low-leakage blocking diode preventing backfeed into primary regulator during power failover. Use Value: 90 K/W Rth(j-sp) allows direct thermal coupling to copper pour; 640 mV max VF ensures <2% voltage drop at 100 mA backup load. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB520S-40T1G (ON Semiconductor) | Same 40 V VR, 1 A IF, but VF = 600 mV typ. @ 1 A; SOD-523 package (smaller: 1.2 × 0.8 mm). | Higher VF increases conduction loss by ~10%; smaller footprint limits thermal dissipation (Rth(j-a) = 500 K/W vs. 450 K/W). | Select when board area is constrained below 1.0 mm² and thermal load remains <300 mW. |
| SBM140 (Diotec) | 40 V VR, 1 A IF, VF = 550 mV typ., but in larger SOD-123 package (3.7 × 1.6 mm); Rth(j-a) = 250 K/W. | Lower thermal resistance supports higher average current in sustained 1 A operation; footprint incompatible with SOD323 land pattern. | Select when thermal margin is prioritized over size and PCB real estate is available for 3.7 mm length. |
Compared with RB520S-40T1G and SBM140, the PMEG4010BEA delivers the best balance of ultra-small size, low VF, and proven thermal performance in SOD323-making it optimal for high-density, thermally managed portable designs where both space and efficiency are co-constrained.

FAQ
What is the maximum allowable soldering temperature profile for PMEG4010BEA?
The PMEG4010BEA is qualified for standard lead-free reflow per JEDEC J-STD-020, with peak temperature up to 260 °C for ≤30 seconds. The recommended reflow footprint uses 0.5 mm wide solder lands per pin (Fig. 5), and thermal relief must avoid excessive copper pour under the cathode pad to prevent tombstoning.
Can PMEG4010BEA be used in automotive applications?
No. Per Nexperia's revision history (v.4, Jan 2023), PMEG4010BEA is explicitly non-automotive qualified. It lacks AEC-Q101 qualification, automotive-grade screening, and extended temperature validation. For automotive use, Nexperia recommends the PMEG4010BEA-Q variant, which undergoes full AEC-Q101 testing and has separate part numbering and qualification documentation.
How does the guard ring affect reverse recovery behavior?
The integrated guard ring does not alter reverse recovery time-it is a structural feature for electric field control, not a charge-storage element. As a Schottky diode, PMEG4010BEA has no minority-carrier storage and exhibits near-zero reverse recovery charge (Qrr ≈ 0), confirmed by absence of Qrr specification in the datasheet and typical fast-switching waveforms in application notes.
Is the marking code 'V3' unique to PMEG4010BEA?
Yes. According to Table 4 of the datasheet, 'V3' is the sole marking code assigned to PMEG4010BEA in the SOD323 package. This two-character laser mark appears on the top surface and is used for traceability and counterfeit detection; no other Nexperia Schottky in SOD323 shares this exact marking.
