Product details
Overview
PMEG4010ER 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 40 V reverse voltage, with a typical forward voltage of 430 mV at 1 A and 25 °C, enabling reduced conduction losses in compact power supplies.
For engineers reviewing the PMEG4010ER datasheet, PMEG4010ER pinout, PMEG4010ER application, or PMEG4010ER equivalent, key selection criteria include its low VF performance, SOD123W package thermal profile, clip-bond construction for enhanced power capability, and verified suitability for SMPS output rectification and battery-input polarity protection circuits.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to improve ruggedness against transient overvoltage and ESD stress. Its clip-bond packaging technique directly connects the die to the lead frame, reducing thermal resistance and supporting higher pulsed current handling (50 A IFSM).
The device operates with minimal forward voltage drop across its rated current range and exhibits low reverse leakage (≤50 µA at 40 V, 25 °C), making it suitable for applications where efficiency and thermal management are critical under ambient temperatures up to 150 °C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VR (Reverse Voltage) | 40 V - Maximum continuous blocking voltage before breakdown; defines usable input/output voltage range in buck converters and reverse protection. |
| IF(AV) (Avg. Forward Current) | 1 A - Sustained DC or square-wave current capability at Tsp ≤ 140 °C; supports 5–12 V output rails in compact adapters. |
| VF (Forward Voltage) | 430–490 mV @ 1 A, 25 °C - Low conduction loss enables >95% efficiency in low-Vout SMPS stages and reduces heat sink requirements. |
| IR (Reverse Current) | 10–50 µA @ 40 V, 25 °C - Minimal leakage preserves battery life in always-on reverse-polarity protection circuits. |
| Rth(j-sp) (Junction-to-Solder Point) | 18 K/W - Enables effective thermal transfer to PCB copper; critical for reliability in high-density layouts without external heatsinking. |
| Cd (Diode Capacitance) | 50 pF @ 10 V, 1 MHz - Low capacitance minimizes switching noise and improves EMI performance in high-frequency (>500 kHz) converters. |
Pinout & Package
Encapsulated in the SOD123W (CFP3) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads optimized for reflow soldering and thermal pad attachment.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to positive rail in reverse polarity protection; carries full load current during normal operation in freewheeling/rectification paths. |
| 2 (A) | Anode | Connected to input/battery side in reverse protection; serves as return path in synchronous rectifier auxiliary configurations. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances surge immunity and long-term reliability under repetitive line transients in industrial DC inputs. |
| Clip-bond construction | Reduces thermal resistance by ~30% vs. wire-bond equivalents, enabling higher power density in space-constrained designs. |
| SOD123W footprint compatibility | Matches JEDEC-standard layout for automated assembly and thermal pad routing per Nexperia's recommended 1 cm² cathode pad. |
| Low VF temperature stability | Forward voltage increases only ~0.2 mV/°C - maintains efficiency consistency across −40 °C to 125 °C operating range. |
Applications
| USB-C Power Delivery Adapter | Industrial 24 V DC Input Module |
|---|---|
|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (520 mV typ @ 1 A), same 40 V VR, larger SOD-123 package (no clip-bond). | Lower thermal performance limits use in >70 °C ambient environments without derating. | Select when legacy footprint compatibility is required and 90 mV VF penalty is acceptable for cost-sensitive designs. |
| SS14 | Same SOD-123W package but higher IR (200 µA @ 40 V) and no guard ring; VF = 500 mV typ. | Not recommended for reverse protection in battery-backed systems due to excessive leakage. | Choose only for non-critical, low-cost consumer SMPS where leakage and surge immunity are not design constraints. |
Compared with RB050M-30 and SS14, PMEG4010ER provides superior thermal performance via clip-bonding, lower leakage for battery-sensitive applications, and guard ring-enhanced robustness-making it the preferred choice for industrial and medical-grade power designs demanding long-term reliability.

FAQ
What is the maximum junction temperature for continuous operation?
The PMEG4010ER has a maximum junction temperature (Tj) rating of 150 °C. Operation at this limit requires strict thermal management-such as using the recommended 1 cm² cathode copper pad on FR4-and derating IF(AV) to 0.8 A at 100 °C ambient per Figure 10. Exceeding 150 °C risks permanent parametric shift or bond failure.
Can PMEG4010ER be used in automotive applications?
No-this part is explicitly marked as non-automotive qualified in the 2023 datasheet revision. It lacks AEC-Q101 qualification, automotive-grade process controls, and extended temperature validation. For automotive use, Nexperia offers the PMEG4010ERE3 (Q101-qualified variant) with identical electrical specs but certified reliability testing.
How does the guard ring improve reliability?
The integrated guard ring mitigates edge electric field crowding, raising the effective breakdown voltage margin and improving resistance to ESD (≥8 kV HBM) and repetitive voltage transients. In practice, this extends service life in unregulated 24 V industrial inputs exposed to load-dump spikes or inductive kickback without additional TVS clamping.
Is the SOD123W package compatible with standard reflow profiles?
Yes-the CFP3 (SOD123W) package is qualified for lead-free reflow per J-STD-020. Nexperia specifies a peak temperature of 260 °C for ≤30 seconds, with ramp rates ≤3 °C/s. The recommended stencil thickness is 0.1 mm, and the footprint (Figure 15) includes 1.1 mm × 1.1 mm solder lands aligned to the 2.6 mm × 1.7 mm body outline.
