Product details
Overview
PMEG4010ETR from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, designed for high-temperature low-VF rectification in compact SMD power supplies. It delivers 1 A average forward current at up to 175 °C junction temperature, 430–490 mV forward voltage at 1 A/25 °C, and 40 V reverse voltage rating - enabling efficient DC-to-DC conversion in space-constrained industrial and automotive-adjacent power modules.
For engineers reviewing the PMEG4010ETR datasheet, PMEG4010ETR pinout, PMEG4010ETR application, or PMEG4010ETR equivalent, key selection criteria include thermal performance on FR4 vs. ceramic PCBs, pulsed reverse leakage behavior at elevated temperature, and clip-bonding-enabled power handling versus standard SOD123 devices.
Technical Context
This Schottky diode uses a planar silicon die with integrated guard ring to suppress edge breakdown and improve reliability under repetitive surge stress. Its clip-bonding construction reduces thermal resistance and enhances current-carrying capability compared to wire-bonded equivalents in the same SOD123W footprint.
The device exhibits ultrafast reverse recovery (trr = 4.4 ns) and low diode capacitance (50 pF at VR = 10 V), making it suitable for high-frequency switching topologies. Forward voltage drops to 290–370 mV at 1 A and 175 °C, supporting stable operation in thermally demanding environments without derating penalties typical of conventional Schottkys.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 1 A - maximum continuous DC or square-wave rectified current at Tsp ≤ 170 °C on standard FR4 PCB |
| VR | 40 V - maximum DC reverse blocking voltage at 25 °C; derates to ~32 V at 175 °C per characteristic curves |
| VF @ 1 A, 25 °C | 430–490 mV - enables >95% efficiency in 5 V–12 V buck converters with minimal conduction loss |
| IR @ 40 V, 25 °C | 10–50 µA - low leakage preserves standby power in always-on systems |
| Tj max | 175 °C - supports operation in engine bay, industrial motor drives, and sealed power enclosures without forced cooling |
| Rth(j-sp) | 18 K/W - thermal resistance from junction to cathode solder point enables direct thermal path to copper pour |
| trr | 4.4 ns - eliminates switching node ringing in MHz-range converters and reduces EMI filter burden |
Pinout & Package
Encapsulated in the CFP3 (SOD123W) surface-mount plastic package: 2.6 mm × 1.7 mm × 1.0 mm body, flat leads, cathode marked by bar on top surface. Optimized for reflow and wave soldering with defined stencil and land patterns per Nexperia footprint guidelines.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Main current exit terminal; large-area tab provides low-inductance, low-resistance thermal and electrical path to PCB copper |
| 2 | Anode (A) | Current entry terminal; smaller pad area reflects lower thermal duty vs. cathode; polarity-sensitive layout critical |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents premature edge breakdown under high dv/dt or mechanical stress, improving long-term reliability in harsh environments |
| Clip-bonding technology | Reduces bond wire inductance and thermal resistance, enabling 1.4 A peak forward current (IF) and 50 A non-repetitive surge capability |
| SOD123W package | Enables 30% higher power density than standard SOD123 while maintaining compatibility with existing pick-and-place and reflow processes |
| 175 °C junction rating | Eliminates need for thermal derating in ambient temperatures up to 140 °C when mounted on FR4 with 1 cm² cathode pad |
| Low VF over temperature | VF drops to 290–370 mV at 175 °C, maintaining high efficiency where conventional Schottkys degrade significantly |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Secondary-side synchronous rectification replacement in isolated 5 V/3.3 V flyback or forward converters operating at 200–500 kHz. IC Role / Device Role / Timing Role: Low-VF unidirectional current valve replacing MOSFET gate drive complexity; handles full load current with <0.5 W conduction loss at 1 A. Use Value: Reduces BOM count and layout area vs. synchronous rectifier IC + MOSFET; maintains >94% efficiency across -40 °C to 125 °C ambient. |
Use Scenario: Input protection for 12 V/24 V industrial controllers exposed to accidental battery reversal during field servicing. IC Role / Device Role / Timing Role: Series-blocking element placed before LDO or DC-DC input; conducts only during correct polarity, clamping reverse voltage to <0.5 V. Use Value: Prevents damage to downstream regulators without adding series resistance or voltage drop in normal operation due to sub-500 mV VF. |
| High-Efficiency Buck Converter Freewheeling | Automotive-Adjacent Power Supply Clamping |
Use Scenario: Freewheeling path in 48 V–12 V buck converters for ADAS domain controllers requiring >96% efficiency at 1–2 A load. IC Role / Device Role / Timing Role: Fast-recovery freewheel diode conducting during high-side switch off-time; complements GaN FET switching at 1 MHz. Use Value: 4.4 ns trr minimizes dead-time losses and voltage overshoot; 50 pF capacitance avoids resonance with PCB trace inductance. |
Use Scenario: Clamp diode in 12 V rail protection circuits for infotainment head units operating near engine compartments (Tamb up to 105 °C). IC Role / Device Role / Timing Role: Transient voltage suppressor for load-dump spikes; leverages 175 °C Tj rating to survive sustained 105 °C board temperature plus self-heating. Use Value: Withstands 50 A IFSM surge without thermal runaway; Rth(j-sp) = 18 K/W ensures rapid heat transfer to chassis ground plane. |
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 NSS40100P5T5G | Same SOD123W package, 40 V/1 A rating, but VF = 490–550 mV @ 1 A/25 °C; no guard ring; Tj max = 150 °C | Limited to lower-temperature applications; higher conduction loss reduces efficiency in high-duty-cycle converters | Select when cost sensitivity outweighs thermal margin and efficiency requirements |
| Vishay VS-1EQH04-M3/86A | DO-214AC (SMA) package, 40 V/1 A, VF = 450–520 mV @ 1 A/25 °C, Tj max = 175 °C, but Rth(j-a) = 110 K/W (vs. 70 K/W for PMEG4010ETR on ceramic) | Requires larger PCB area; less effective thermal management in dense layouts; not SMD footprint-compatible | Select only when legacy SMA footprint must be retained and thermal design allows larger heatsinking |
Compared with NSS40100P5T5G and VS-1EQH04-M3/86A, PMEG4010ETR offers superior thermal performance in miniaturized layouts, lower forward voltage across its full temperature range, and integrated guard ring protection - making it optimal for next-generation high-density, high-reliability power stages.

FAQ
What is the maximum allowable ambient temperature for continuous 1 A operation on standard FR4?
At δ = 0.5 (50% duty cycle), f = 20 kHz square wave, the PMEG4010ETR sustains 1 A average forward current up to 140 °C ambient on standard FR4 with single-sided copper. This is confirmed in Figure 11 of the datasheet, where IF(AV) = 1 A intersects Tamb ≈ 140 °C for δ = 0.5 curve. Derating applies above this point.
Does PMEG4010ETR support automotive qualification?
No - the PMEG4010ETR is explicitly designated as non-automotive qualified per Revision History section 14. It lacks AEC-Q101 stress testing and automotive-grade process controls. For automotive use, Nexperia offers the PMEG4010ET,115-Q variant, which undergoes full AEC-Q101 qualification and includes additional screening.
How does the guard ring affect voltage standoff reliability?
The integrated guard ring mitigates electric field crowding at the silicon periphery, raising the practical reverse breakdown voltage margin by ~15–20% under mechanical stress or contamination. This extends lifetime in humid, vibration-prone, or thermally cycled applications - validated through accelerated life testing per JEDEC JESD22-A108.
Can PMEG4010ETR replace standard SOD123 Schottkys in existing layouts?
Yes - the SOD123W (CFP3) footprint is mechanically compatible with standard SOD123 pads, though optimized land patterns are recommended (see Figure 19). Electrical improvements - lower VF, higher Tj, and better surge rating - deliver immediate system-level benefits without layout changes, provided thermal relief and solder mask definition meet Nexperia's guidelines.
