Product details
Overview
PMEG4010CEGWJ from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 40 V reverse voltage and 1 A average forward current, featuring low 490 mV typical forward voltage and 6 µA typical reverse leakage - deployed in DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4010CEGWJ datasheet, PMEG4010CEGWJ pinout, PMEG4010CEGWJ application, or PMEG4010CEGWJ equivalent, this page delivers verified electrical parameters, SOD123 package layout, thermal resistance values (Rth(j-sp) = 185 K/W), and real-world use cases in low-power SMPS and battery-powered systems.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance ruggedness against transient overvoltage and electrostatic stress. Its low VF enables high efficiency in low-voltage rectification paths where conduction loss dominates.
Thermal performance is defined by junction-to-solder-point resistance of 185 K/W on FR4 PCB with cathode pad, and junction-to-ambient resistance of 305 K/W in free air - critical for compact power stage layouts with limited copper area.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability without breakdown under steady-state DC conditions. |
| Average Forward Current (IF(AV)) | 1 A - continuous DC current rating at Tsp ≤ 135 °C with 50% duty cycle square wave. |
| Forward Voltage (VF) | 490 mV typ. at IF = 1 A - reduces conduction loss in high-efficiency buck converters and OR-ing circuits. |
| Reverse Leakage (IR) | 6 µA typ. at VR = 40 V - minimizes standby power loss in battery-backed systems. |
| Diode Capacitance (Cd) | 69 pF typ. at VR = 1 V, 1 MHz - limits switching noise and EMI in high-frequency SMPS designs. |
| Junction Temperature (Tj) | 150 °C max - defines thermal headroom for operation in sealed enclosures or high ambient environments. |
Pinout & Package
Encapsulated in a compact SOD123 surface-mount plastic package (2.675 mm × 1.6 mm × 1.15 mm body), with cathode marked by a bar on the device top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative output terminal; connects to load ground or return path; marked by bar on package. |
| 2 | Anode (A) | Positive input terminal; connects to source rail or switch node; carries full forward current. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves surge robustness and prevents edge breakdown during voltage transients. |
| Low thermal resistance Rth(j-sp) | 185 K/W enables higher power density on standard FR4 PCBs without thermal vias. |
| Small SOD123 footprint | Reduces board area by >40% vs. SMA packages while maintaining 1 A current handling. |
| Low VF / low IR trade-off | Optimized for <12 V systems where both conduction loss and standby leakage impact efficiency. |
Applications
| Battery-Powered IoT Node | USB-C Power Delivery Input Stage |
|---|---|
Use Scenario: Reverse polarity protection for coin-cell or Li-ion powered sensor nodes with tight space constraints. IC Role / Device Role / Timing Role: Unidirectional current gate preventing damage from incorrect battery insertion. Use Value: 490 mV VF limits voltage drop to <2% at 1 A, preserving runtime; 6 µA IR extends shelf life beyond 10 years. |
Use Scenario: Input OR-ing diode in dual-input USB-C PD adapter supporting 5–20 V input rails. IC Role / Device Role / Timing Role: Prevents backfeed between sources while enabling seamless switchover. Use Value: 40 V VR rating covers full USB PD range; SOD123 size fits dense multi-rail PCB layouts. |
| Point-of-Load DC-DC Converter | Industrial Sensor Signal Conditioning |
Use Scenario: Output rectification in 3.3 V/1 A synchronous buck converter operating at 500 kHz. IC Role / Device Role / Timing Role: Freewheeling path during high-side FET off-time. Use Value: 69 pF Cd minimizes switching node ringing; low VF improves light-load efficiency by >3%. |
Use Scenario: Clamp protection and signal rectification in 4–20 mA loop-powered analog sensors. IC Role / Device Role / Timing Role: Overvoltage clamp and AC signal demodulation element. Use Value: Guard ring ensures reliability under 2 kV ESD events per IEC 61000-4-2; 150 °C Tj supports extended temperature operation. |
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 NSR0140HT1G | Same SOD123 package; 40 V VR, 1 A IF(AV), but VF = 550 mV typ. at 1 A - 60 mV higher conduction loss. | Slightly lower efficiency in high-current DC-DC outputs; identical footprint allows drop-in replacement. | Prefer when supply chain diversification is required and 60 mV VF penalty is acceptable. |
| Vishay SS12 | SMA package (larger); 20 V VR, 1 A IF(AV), VF = 500 mV - insufficient reverse voltage for 40 V bus applications. | Not suitable for 36–40 V industrial inputs; requires PCB redesign due to larger footprint and different thermal pad. | Select only if 20 V rating suffices and legacy SMA placement exists; not recommended for new 40 V designs. |
Compared with NSR0140HT1G and SS12, PMEG4010CEGWJ delivers the lowest forward voltage in its class while maintaining full 40 V blocking and SOD123 compactness - making it optimal for space-constrained, high-efficiency 12–36 V systems where thermal margin and leakage are critical.

FAQ
What is the maximum repetitive peak forward current (IFRM) for PMEG4010CEGWJ?
The maximum repetitive peak forward current is 7 A at pulse width ≤ 1 ms and duty cycle ≤ 0.25. This rating applies under pulsed conditions and supports short-duration inrush or transient currents without thermal runaway, provided average power dissipation remains within 410 mW at 25 °C ambient.
Does PMEG4010CEGWJ have automotive qualification?
No. Per Nexperia's revision history, PMEG4010CEGWJ is explicitly designated as non-automotive; it lacks AEC-Q101 qualification and has not undergone automotive-grade stress testing. For automotive applications, select the -Q qualified variant (e.g., PMEG4010CEGWJ-Q).
How does the guard ring improve reliability in PMEG4010CEGWJ?
The integrated guard ring mitigates electric field crowding at the silicon edge, raising the effective breakdown voltage and improving immunity to ESD and fast transient surges. It enables stable operation under repeated 2 kV HBM ESD events and line transients up to 40 V without parameter shift or failure.
What is the recommended solder pad layout for PMEG4010CEGWJ on FR4?
Nexperia specifies a 1 cm² copper pad for the cathode terminal to achieve the rated Rth(j-sp) = 185 K/W. The reflow footprint (Fig. 8) defines solder paste stencil openings of 0.81 mm × 2.36 mm for anode and 0.91 mm × 4.18 mm for cathode, with 1.11 mm solder resist clearance.
