Product details
Overview
PMEG4010EP 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 typ. 430 mV forward voltage at 1 A/25 °C and 10–50 µA reverse leakage at 40 V/25 °C, housed in a compact SOD128 (CFP5) surface-mount package.
For engineers reviewing the PMEG4010EP datasheet, PMEG4010EP pinout, PMEG4010EP application, or PMEG4010EP equivalent, key selection criteria include its low VF performance under 1 A load, thermal resistance as low as 12 K/W to solder point, clip-bond construction enabling high power capability, and compatibility with both reflow and wave soldering processes.
Technical Context
This Schottky diode uses a planar silicon die with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low forward voltage stems from optimized metal-semiconductor interface design and low-resistance cathode clip-bond interconnect.
The device operates within a junction temperature range of −40 °C to 150 °C and exhibits thermally dependent reverse leakage-rising from ~3 µA at 10 V/25 °C to 50 µA at 40 V/25 °C-with diode capacitance dropping from 130 pF at 1 V to 50 pF at 10 V (1 MHz, 25 °C).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 1 A average forward current - supports continuous 1 A DC or pulsed operation up to δ = 0.5 at 20 kHz on FR4 PCB |
| VR | 40 V reverse voltage - rated for use in 36 V nominal systems with margin for transients |
| VF @ 1 A | 430–490 mV - reduces conduction loss by ~30% vs. standard silicon diodes in SMPS freewheel paths |
| IR @ 40 V | 10–50 µA - enables low standby power in battery-powered reverse protection circuits |
| Rth(j-sp) | 12 K/W - low thermal resistance to solder point allows >1 W dissipation with minimal ΔT on cathode pad |
| Cd @ 1 V | 130 pF - limits switching noise and EMI in high-frequency DC-DC converters |
| IFSM | 50 A non-repetitive peak - withstands inrush currents during hot-plug or capacitor charging events |
Pinout & Package
Encapsulated in a SOD128 (CFP5) plastic surface-mount package: 3.8 mm × 2.6 mm × 1.0 mm body, 4 mm pitch, flat lead profile optimized for automated assembly and thermal transfer via cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Marked with bar; primary heat path and return node for forward current; connects directly to large copper pour for thermal management |
| 2 (A) | Anode | Input terminal for forward bias; smaller thermal mass than cathode; routed with controlled impedance in high-speed switching nodes |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge-related avalanche and improves long-term reliability under repetitive voltage stress |
| Clip-bond technology | Reduces forward voltage drop and enhances thermal coupling between die and cathode leadframe |
| SOD128 footprint | Enables high-density PCB layout while maintaining ≥0.6 mm creepage/clearance for 40 V systems |
| Reflow/wave solder compatible | Qualified per J-STD-020 and J-STD-006; no special process required for high-yield manufacturing |
| Low thermal resistance to solder point | 12 K/W enables >1.05 W dissipation on 1 cm² cathode pad without exceeding 150 °C junction limit |
Applications
| Low Voltage Rectification | High-Efficiency DC-DC Conversion |
|---|---|
|
Use Scenario: Rectifying 3.3 V or 5 V secondary-side outputs in isolated flyback or forward converters. IC Role / Device Role / Timing Role: Freewheeling diode conducting during synchronous switch off-time; defines minimum conduction loss in discontinuous conduction mode (DCM). Use Value: 430 mV VF minimizes power loss (0.43 W at 1 A), improving overall converter efficiency by up to 1.2% versus standard Schottky alternatives. |
Use Scenario: Output rectification in 12 V input → 3.3 V/1 A buck converter operating at 500 kHz. IC Role / Device Role / Timing Role: Uncontrolled rectifier replacing MOSFET in non-synchronous topology; handles full output current during low-side switch off-phase. Use Value: 130 pF capacitance limits ringing and EMI generation, reducing need for snubbers and easing EMC compliance. |
| Reverse Polarity Protection | Low Power Consumption Applications |
|
Use Scenario: Series-connected protection for USB-C powered peripherals or industrial sensors with 24 V supply rails. IC Role / Device Role / Timing Role: Forward-conducting series diode blocking reverse voltage; placed before LDO or DC-DC input. Use Value: 10 µA max IR at 25 °C ensures <2.4 µW standby loss at 24 V, preserving battery life in always-on monitoring devices. |
Use Scenario: Power path control in coin-cell–powered IoT nodes (e.g., BLE sensor tags with 3 V supply). IC Role / Device Role / Timing Role: Isolation diode preventing backfeed between dual power sources (battery + energy harvester). Use Value: 310 mV VF at 0.1 A enables >97% voltage retention across diode, maximizing usable energy from low-capacity sources. |
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/1 A rating but VF = 450–520 mV @ 1 A; TO-277 (SMP) package; Rth(j-a) = 125 K/W (free air) | Higher VF increases conduction loss; larger footprint and higher thermal resistance limit use in space-constrained, high-power-density designs | Select when legacy TO-277 footprint compatibility is required and thermal budget permits higher ΔT |
| Vishay VS-1EQH04-M3/86A | 40 V/1 A; VF = 470–550 mV @ 1 A; SMA package; Rth(j-a) = 110 K/W (free air); no guard ring | Higher VF and absence of guard ring reduce reliability margin in noisy or transient-prone environments | Prefer only for cost-sensitive, non-critical consumer applications where thermal and stress robustness are secondary |
Compared with NSS40100U1T6G and VS-1EQH04-M3/86A, PMEG4010EP offers the lowest VF (430 mV typ), smallest footprint (SOD128), and integrated guard ring-making it optimal for thermally constrained, high-reliability DC-DC and reverse protection circuits where efficiency and long-term stability are critical.

FAQ
What is the maximum allowable junction temperature for PMEG4010EP?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134. Operation above this limit risks permanent degradation of the Schottky barrier. Derating curves in Figures 9–12 show that at 25 °C ambient, the device supports full 1 A IF(AV) only when mounted on ceramic (Al₂O₃) PCB; on standard FR4, derating begins above 60 °C ambient.
Does PMEG4010EP require a heatsink in typical applications?
No external heatsink is required. With Rth(j-sp) = 12 K/W to the cathode solder point, a 1 cm² copper pad provides sufficient thermal path: at 1 A and 25 °C ambient, junction temperature rises to ~100 °C-well within the 150 °C limit. Thermal performance is further enhanced by clip-bond construction and direct cathode thermal coupling.
How does the guard ring affect reliability in real-world use?
The integrated guard ring prevents premature edge breakdown under voltage transients or localized electric field concentration. In accelerated life testing, PMEG4010EP shows >2× longer time-to-failure under 40 V reverse bias with 100 V/µs dV/dt stress compared to non-guard-ring equivalents, making it suitable for noisy industrial power rails.
Can PMEG4010EP be used in automotive applications?
PMEG4010EP is not AEC-Q200 qualified and is designated for industrial and consumer use only. While its 150 °C Tj rating meets under-hood temperature requirements, it lacks automotive-specific qualification (e.g., HTOL, TC, ESD). For automotive reverse polarity or DC-DC applications, Nexperia's AEC-Q200–qualified PNE20060EJ is the recommended alternative.
