Product details
Overview
PMEG4010EGWJ from Nexperia is a 40 V, 1 A planar Schottky barrier rectifier in SOD123 package, featuring low forward voltage (540 mV typ. at 1 A), low reverse leakage (30 µA typ. at 40 V), and integrated guard ring for stress protection-used in DC-DC converter output rectification and reverse polarity protection circuits.
For engineers reviewing the PMEG4010EGWJ datasheet, PMEG4010EGWJ pinout, PMEG4010EGWJ application, or PMEG4010EGWJ equivalent, key selection criteria include forward voltage drop at 1 A, thermal resistance to solder point (190 K/W), reverse breakdown margin, junction temperature limit (150 °C), and SOD123 footprint compatibility with high-density PCB layouts.
Technical Context
This MEGA Schottky rectifier uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low VF stems from optimized metal–semiconductor interface and thin epitaxial layer design.
It operates within a junction temperature range of −40 °C to 150 °C and delivers stable performance up to 1 A average forward current when mounted on FR4 with 1 cm² cathode pad; pulsed peak current capability reaches 9 A for 8 ms non-repetitive events.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 540 mV typ. at 1 A, 25 °C - enables <1.5 W conduction loss in 5 V/1 A output rails |
| Reverse Voltage (VR) | 40 V max - supports 36 V nominal input systems with 10 % margin for transients |
| Reverse Current (IR) | 30 µA typ. at 40 V - minimizes standby power loss in battery-backed circuits |
| Junction Temperature (Tj) | 150 °C max - allows operation in sealed industrial enclosures without active cooling |
| Thermal Resistance (Rth(j-sp)) | 190 K/W - enables 0.66 W dissipation with ≤125 °C solder point rise above 25 °C ambient |
| Diode Capacitance (Cd) | 43 pF typ. at 1 V - reduces switching noise and EMI in 500 kHz–1 MHz DC-DC converters |
Pinout & Package
Encapsulated in 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) | Connected to load/positive rail side; marking bar identifies this terminal; requires thermal pad for heat transfer |
| 2 | Anode (A) | Connected to source/negative rail side; no internal thermal path; standard trace routing suffices |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown under voltage surge or mechanical stress, improving long-term reliability in unregulated inputs |
| Low VF at high IF | 540 mV @ 1 A enables >92 % efficiency in 5 V buck converter outputs with minimal heatsinking |
| SOD123 footprint | Standardized 2.675 mm × 1.6 mm outline compatible with automated placement and reflow profiles per IPC-7095 |
| Non-automotive qualified | Rated for industrial and consumer applications only; not tested to AEC-Q101 or automotive temperature cycling requirements |
Applications
| DC-DC Converter Output Rectification | Reverse Polarity Protection |
|---|---|
Use Scenario: Used as secondary-side synchronous rectifier replacement in 5 V/1 A isolated flyback or buck converter. IC Role / Device Role / Timing Role: Uncontrolled passive rectifier conducting during positive half-cycle of transformer secondary or switch node swing. Use Value: 540 mV VF reduces conduction loss by ~35 % versus standard PN diodes, lowering thermal load on compact PCBs. |
Use Scenario: Placed in series with VIN to block reverse supply connection in USB-powered peripherals. IC Role / Device Role / Timing Role: Forward-biased conductor during normal operation; reverse-biased open circuit during miswiring. Use Value: 30 µA IR at 40 V limits reverse leakage to <1.2 µW, preserving battery life in always-on devices. |
| Low-Voltage AC Adapter Rectification | Low-Power Standby Supply |
Use Scenario: Full-wave rectification stage in 12 V AC-to-DC wall adapters delivering ≤1 A. IC Role / Device Role / Timing Role: Half-wave or bridge leg rectifier handling 50/60 Hz line-frequency current pulses. Use Value: 1 A average rating and 9 A IFSM withstand brief inrush surges from capacitive loads without degradation. |
Use Scenario: Input rectifier for 3.3 V/100 mA auxiliary supply powering MCU reset logic and RTC. IC Role / Device Role / Timing Role: Primary conduction path during main power availability; zero-current blocking during shutdown. Use Value: 43 pF capacitance avoids signal coupling into sensitive analog rails, maintaining clean LDO input ripple. |
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 VR, 1 A IF, but VF = 550 mV typ.; Rth(j-a) = 320 K/W (vs. 190 K/W for PMEG4010EGWJ) | Larger SOD-123FL package (3.0 mm × 1.7 mm); less thermal efficiency on small pads | Select when footprint tolerance allows larger body or when ON Semi supply chain preference applies |
| Vishay SS14-E3/57T | 40 V VR, 1 A IF, VF = 550 mV typ., but IR = 500 µA typ. at 40 V (16× higher leakage) | No guard ring; lower surge robustness; rated for commercial temp only (−55 °C to 125 °C) | Acceptable for cost-sensitive consumer designs where leakage <100 µA is tolerable and surge immunity is non-critical |
Compared with NSS40100U1T6G and SS14-E3/57T, PMEG4010EGWJ offers superior thermal performance via lower Rth(j-sp), tighter IR control for ultra-low-power systems, and guard ring–enhanced ruggedness-making it preferred for space-constrained industrial power rails requiring long-term stability.

FAQ
What is the maximum allowable junction temperature for continuous operation?
The absolute maximum junction temperature is 150 °C. Continuous operation must ensure Tj remains below this limit under worst-case ambient, power dissipation, and PCB thermal conditions. Derating is required above 25 °C ambient, with full 1 A rating valid only when solder point temperature stays ≤130 °C per datasheet limiting values.
Is PMEG4010EGWJ suitable for automotive applications?
No. This part is explicitly designated as non-automotive qualified in the revision history and legal disclaimers. It lacks AEC-Q101 qualification, automotive-grade testing, and extended temperature validation beyond −40 °C to +150 °C junction range. Automotive use requires Nexperia's -Q qualified equivalents.
How does the guard ring improve reliability in real-world circuits?
The integrated guard ring mitigates electric field crowding at the die edge, preventing premature avalanche breakdown during voltage transients or mechanical stress-induced microcracks. This extends operational lifetime in unregulated inputs, such as 24 V industrial supplies subject to load dump or inductive kickback.
Can PMEG4010EGWJ replace a standard PN rectifier like 1N4007 in low-frequency applications?
Yes, but only where reverse voltage ≤40 V and average current ≤1 A. Unlike the 1N4007 (1000 V, 1 A), PMEG4010EGWJ offers far lower VF and faster recovery, reducing losses-but its lower VR makes it unsafe in 120/230 VAC front-end rectification. Use only in low-voltage DC-fed circuits.
