Product details
Overview
PMEG4010EJ,115 from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 40 V reverse voltage and 1 A forward current, featuring a typical forward voltage of 540 mV at 1 A and reverse leakage of 30 µA at 40 V. It is designed for low-voltage, high-efficiency DC-to-DC conversion in space-constrained SMD applications.
For engineers reviewing the PMEG4010EJ,115 datasheet, PMEG4010EJ,115 pinout, PMEG4010EJ,115 application, or PMEG4010EJ,115 equivalent, key selection criteria include ultra-low VF performance, thermal resistance to solder point (150 K/W), SC-90 package footprint compatibility, and non-automotive qualification status per revision v.6 (2024).
Technical Context
This Schottky diode uses a planar die structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reliability under repetitive surge conditions. Its low junction-to-solder-point thermal resistance (150 K/W) supports stable operation in thermally dense PCB layouts when mounted on FR4 with 1 cm² cathode pad.
The device exhibits strong temperature-dependent VF behavior - dropping from ~640 mV at 25 °C to ~420 mV at 150 °C at 1 A - and reverse leakage increases exponentially with temperature, reaching 100 µA at 25 °C and up to 10⁵ µA at 150 °C under 40 V bias.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - maximum blocking capability without breakdown; defines usable input range in buck converters or reverse polarity protection circuits. |
| Forward Current (IF) | 1 A continuous - sustained conduction rating at ≤55 °C solder point temperature; supports compact 1 A power rail rectification. |
| Forward Voltage (VF) | 540 mV typ. @ 1 A - enables >95% efficiency in 3.3 V–5 V DC-DC outputs by minimizing conduction loss. |
| Reverse Leakage (IR) | 30 µA typ. @ 40 V, 25 °C - low leakage preserves battery life in always-on low-power systems. |
| Diode Capacitance (Cd) | 43 pF typ. @ 1 V, 1 MHz - limits high-frequency switching noise and EMI in SMPS feedback paths. |
| Junction-to-Ambient Rth | 350 K/W - requires careful PCB copper area design to avoid thermal runaway under sustained load. |
| Package | SOD323F (SC-90) - 1.7 mm × 1.25 mm × 0.7 mm footprint ideal for wearables and IoT sensor nodes. |
Pinout & Package
Encapsulated in the SOD323F (SC-90) surface-mount plastic package: 2-terminal, single-die Schottky rectifier with cathode (K) and anode (A) terminals exposed on opposite ends of the 1.7 mm × 1.25 mm body.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output/low-side terminal; connects to ground or return path; carries full forward current and dissipates majority of heat via solder pad. |
| 2 | Anode (A) | Input/high-side terminal; connects to unregulated input or positive rail; electrically isolated from cathode by Schottky junction. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and transient overvoltage robustness without increasing VF or capacitance. |
| Ultra-low VF at 1 A | 540 mV typ. - reduces I²R losses by ~40% vs. standard Schottkys with VF > 700 mV in 1 A DC-DC stages. |
| Low thermal resistance to solder point | 150 K/W - enables direct thermal coupling to PCB copper, critical for thermal management in sealed enclosures. |
| Reflow-only assembly | Qualified only for reflow soldering - eliminates risk of thermal damage during hand-soldering or wave processes. |
| Non-automotive qualification | Per revision v.6 (Feb 2024); not tested to AEC-Q101 - intended for industrial, consumer, and computing applications only. |
Applications
| USB Power Delivery Interface | IoT Sensor Node Power Path |
|---|---|
|
Use Scenario: Bidirectional 5 V power routing between USB-C port and system battery with reverse polarity and backfeed prevention. IC Role / Device Role / Timing Role: Low-loss, fast-recovery reverse-blocking diode in power-path OR-ing configuration. Use Value: 540 mV VF minimizes voltage drop across diode, preserving >4.45 V at load under 1 A; 43 pF capacitance avoids signal integrity issues on CC lines. |
Use Scenario: Input rectification for coin-cell or energy-harvesting supply feeding ultra-low-power microcontroller and BLE radio. IC Role / Device Role / Timing Role: Primary DC rectifier converting harvested AC or pulsed DC into stable DC bus. Use Value: 30 µA IR at 25 °C prevents >1% battery drain in sleep mode; SC-90 footprint fits sub-10 mm² PCB area budgets. |
| Point-of-Load DC-DC Output Stage | Industrial Control Signal Protection |
|
Use Scenario: Synchronous rectifier replacement in 3.3 V/1 A buck converter output stage where gate drive complexity must be avoided. IC Role / Device Role / Timing Role: Freewheeling diode conducting during high-side FET off-time in non-synchronous topology. Use Value: 640 mV max VF ensures <1.2% efficiency penalty vs. ideal synchronous rectifier; 9 A IFSM withstands startup surges. |
Use Scenario: Reverse-polarity protection on 24 V auxiliary supply inputs to PLC I/O modules exposed to field wiring errors. IC Role / Device Role / Timing Role: Series-connected protection diode blocking reverse voltage before LDO or regulator input. Use Value: 40 V VR rating provides 2× margin over 24 V nominal; guard ring prevents latch-up during 1 kV EFT bursts per IEC 61000-4-4. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB521S-40T1G | VF = 370 mV typ. @ 100 mA; IR = 100 µA @ 40 V; same SOD-523 package (smaller than SOD323F). | Lower IF rating (200 mA) limits use to sub-0.2 A loads; higher IR reduces suitability for battery-critical designs. | Select only for <200 mA, ultra-small-footprint applications where VF at low current matters more than surge capability. |
| SS12 | VF = 500 mV typ. @ 1 A; VR = 20 V; DO-214AC package (larger, through-hole compatible). | Half the VR rating restricts use to ≤12 V systems; 7.1 mm × 2.8 mm body incompatible with fine-pitch SMT lines. | Choose only for cost-sensitive, non-SMT legacy designs requiring 1 A/20 V rectification with manual assembly support. |
Compared with RB521S-40T1G and SS12, PMEG4010EJ,115 uniquely balances 1 A continuous rating, 40 V blocking, ultra-low VF at full load, and SOD323F manufacturability - making it optimal for modern 1 A DC-DC outputs where thermal density and board area are constrained.

FAQ
Is PMEG4010EJ,115 qualified for automotive applications?
No. Per Nexperia's revision v.6 (February 2024), PMEG4010EJ,115 is explicitly designated as non-automotive qualified. It has not undergone AEC-Q101 stress testing or PPAP documentation. For automotive use, Nexperia offers the -Q qualified variants such as PMEG4010EJ-Q, which are separately specified and tested.
What is the maximum allowable soldering temperature profile for PMEG4010EJ,115?
PMEG4010EJ,115 is qualified for reflow soldering only, per datasheet section 13. The peak temperature must not exceed 260 °C for ≤10 seconds, with ramp-up ≤3 °C/s and ramp-down ≤6 °C/s. Wave or hand soldering is not recommended and may cause permanent parameter shift or bond wire failure.
Can PMEG4010EJ,115 replace a standard PN-junction diode like 1N4148 in signal clamping?
No. While it conducts at lower voltage, PMEG4010EJ,115 is optimized for power rectification - its 43 pF capacitance and lack of specified reverse recovery time make it unsuitable for high-speed signal clamping. The 1N4148 offers 4 pF capacitance and 4 ns trr, whereas this Schottky's soft recovery and higher Cd degrade signal edge fidelity above 10 MHz.
How does the guard ring affect layout requirements for PMEG4010EJ,115?
The integrated guard ring requires ≥0.25 mm clearance between the cathode pad and any adjacent copper pour or trace, as specified in Nexperia's SC-90 footprint guidelines. Violating this spacing risks electric field crowding and premature breakdown under transient voltage stress, especially in high-humidity or contaminated environments.
