Product details
Overview
PMEG4010EPK-QYL from Nexperia is a 40 V, 1 A planar Schottky barrier rectifier with integrated guard ring for stress protection, housed in an ultra-small leadless DFN1608D-2 (SOD1608) package. It delivers low forward voltage (540–600 mV @ 1 A), ultra-fast reverse recovery (<3 ns), and AEC-Q101 qualification-enabling use in automotive LED backlighting and high-efficiency DC-DC converters where space, thermal performance, and reliability are critical.
For engineers reviewing the PMEG4010EPK-QYL datasheet, PMEG4010EPK-QYL pinout, PMEG4010EPK-QYL application, or PMEG4010EPK-QYL equivalent, key selection criteria include its 0.37 mm profile, side-wettable flanks for solder joint inspection, 150 °C max junction temperature, and verified performance under pulsed 1 A forward current and 40 V reverse bias.
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve robustness against transient overvoltage and thermal stress. Its low VF and negligible minority-carrier storage enable operation at frequencies up to several MHz without significant switching loss.
The device is optimized for reflow-only assembly on FR4 or ceramic PCBs, with thermal resistance from junction to solder point as low as 20 K/W when mounted on a 1 cm² cathode pad. Its binary marking "1010" and cathode bar orientation support automated optical inspection in high-volume SMT lines.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum continuous blocking capability; suitable for 36 V automotive rail and 24 V industrial systems. |
| Average Forward Current (IF(AV)) | 1 A - Sustained DC or pulsed current handling at ≤90 °C ambient on ceramic PCB; derates to 0.8 A at 125 °C on FR4. |
| Forward Voltage (VF) | 540–600 mV @ 1 A - Reduces conduction loss by >30% vs. standard PN diodes, improving efficiency in battery-powered DC-DC stages. |
| Reverse Recovery Time (trr) | <3 ns - Enables ultra-high-frequency switching (>10 MHz) without tail current or ringing in synchronous rectifiers. |
| Reverse Current (IR) | 0.6–4 µA @ 10 V - Low leakage preserves standby power in always-on circuits like automotive infotainment wake-up paths. |
| Thermal Resistance (Rth(j-sp)) | 20 K/W - Achieved with cathode-side thermal pad; enables direct heat transfer to PCB copper, supporting compact thermal design. |
| Package Dimensions | 1.6 mm × 0.8 mm × 0.37 mm - Ultra-compact footprint fits 0402-class board area; side-wettable flanks allow automated X-ray/solder-joint inspection. |
Pinout & Package
Encapsulated in a leadless DFN1608D-2 (SOD1608) plastic package with visible and solderable side pads, height 0.37 mm, pitch 0.94 mm, and cathode-marked top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Main current exit terminal; connected to thermal pad for enhanced heat dissipation; marked with cathode bar on top surface. |
| 2 (A) | Anode | Current entry terminal; electrically isolated from thermal path; requires precise stencil aperture for reliable reflow wetting. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including temperature cycling, HAST, and mechanical shock per JESD22 standards. |
| Solderable side pads | Enables automated optical inspection (AOI) of solder fillets without X-ray; improves process yield in high-reliability SMT lines. |
| Integrated guard ring | Suppresses edge-related avalanche and leakage at high VR, increasing long-term reliability in transient-prone automotive environments. |
| Ultra-low profile (0.37 mm) | Permits stacking under thin displays or within tight gaps in portable electronics; compatible with conformal coating processes. |
| Low thermal resistance to solder point | 20 K/W to cathode solder point allows direct thermal coupling to inner-layer ground planes-critical for thermally constrained modules. |
Applications
| Automotive LED Backlighting | USB-C Power Delivery Rectification |
|---|---|
|
Use Scenario: High-brightness LED strings in instrument clusters and center displays powered from 12 V automotive rail. IC Role / Device Role / Timing Role: Output rectifier in buck-boost LED driver; handles bidirectional current during PWM dimming transitions.

IC Role / Device Role / Timing Role: Series-connected protection diode placed before LDO or DC-DC regulator input. Use Value: 40 V VR withstands load-dump transients (ISO 7637-2 Pulse 5a); 0.6 µA IR at 10 V ensures <1 µW standby loss. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-1EQH04-M3/86A | 40 V, 1 A, VF = 550 mV @ 1 A; TO-277 package (3.05 mm × 1.65 mm × 1.05 mm); no side-wettable flanks. | Larger footprint and height limit use in ultra-thin devices; lacks AEC-Q101 certification. | Select when board space permits larger package and automotive qualification is not required. |
| ON Semiconductor NSR1040HT1G | 40 V, 1 A, VF = 580 mV @ 1 A; SOD-123FL package (2.8 mm × 1.7 mm × 1.0 mm); Rth(j-a) = 220 K/W (vs. 80 K/W for PMEG4010EPK-QYL on ceramic). | Higher thermal resistance limits power density; not AEC-Q101 qualified. | Choose for cost-sensitive consumer applications where thermal performance and automotive compliance are secondary. |
Compared with VS-1EQH04-M3/86A and NSR1040HT1G, PMEG4010EPK-QYL offers superior board-area efficiency, certified automotive reliability, and 3× lower thermal resistance-making it optimal for space-constrained, thermally demanding, and safety-critical designs.

FAQ
Is PMEG4010EPK-QYL suitable for reflow soldering only?
Yes-Nexperia specifies reflow soldering as the sole recommended method. The DFN1608D-2 package is not rated for wave or hand soldering due to thermal stress risks on side-wettable flanks and internal die attach. Reflow profiles must comply with JEDEC J-STD-020, peak temperature ≤260 °C, and time above 217 °C limited to 60–90 seconds.
What does the "QYL" suffix indicate in PMEG4010EPK-QYL?
The "QYL" suffix denotes Nexperia's tape-and-reel packaging variant with 10,000 units per reel, moisture sensitivity level (MSL) 1, and compliance with AEC-Q101 stress testing. It shares identical electrical and thermal specifications with the base PMEG4010EPK-Q part but is optimized for high-speed pick-and-place assembly.
How does the guard ring improve reliability in automotive applications?
The integrated guard ring reduces electric field crowding at the silicon periphery, suppressing premature edge breakdown during load-dump transients (ISO 7637-2 Pulse 5a) and temperature cycling. This extends operational lifetime under repeated thermal stress and prevents parametric drift in high-humidity underhood environments.
Can PMEG4010EPK-QYL replace a standard 1N5819 in existing designs?
Yes-with layout adaptation. While both are 40 V/1 A Schottky diodes, PMEG4010EPK-QYL uses a 1.6 mm × 0.8 mm DFN package versus the 1N5819's DO-27 (5.2 mm × 2.7 mm). Pad redesign is required for side-wettable flanks, and thermal simulation should confirm junction temperature remains ≤150 °C given its lower Rth(j-sp) and higher power density.
