Product details
Overview
PMEG4010AESBYL from Nexperia is a 40 V, 1 A low forward-voltage Schottky barrier rectifier in an ultra-small DSN1006-2 (SOD993) surface-mount package, designed for high-efficiency DC-to-DC conversion and low-voltage rectification in space-constrained portable electronics. It features a typical forward voltage of 435 mV at 1 A, reverse current of 325 µA at 40 V, and thermal resistance of 70 K/W on ceramic PCB - enabling compact, thermally efficient power rail design.
For engineers reviewing the PMEG4010AESBYL datasheet, PMEG4010AESBYL pinout, PMEG4010AESBYL application, or PMEG4010AESBYL equivalent, key selection criteria include ultra-low VF for minimal conduction loss, sub-300 µm profile for thin-profile mobile designs, integrated guard ring for ESD/overstress robustness, and verified performance under pulsed 20 kHz square-wave operation up to 145 °C solder point temperature.
Technical Context
This MEGA Schottky rectifier uses planar silicon technology with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress. Its low junction capacitance (22 pF at 10 V) and ultra-fast reverse recovery time (3.1 ns) support high-frequency switching in buck converters and LED drivers.
The device operates within a −55 °C to 150 °C junction temperature range and delivers 1 A average forward current under 20 kHz square-wave excitation with 0.5 duty cycle and ≤145 °C solder point temperature - validated for FR4 and Al₂O₃ PCB mounting configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports input rails up to 36 V nominal in industrial and portable DC/DC stages without derating. |
| Average Forward Current (IF(AV)) | 1 A - rated for continuous conduction at 20 kHz, 0.5 duty cycle, ≤145 °C solder point on standard FR4. |
| Forward Voltage (VF) | 435 mV typ. at 1 A - reduces conduction loss by >30% vs. standard Schottkys, improving efficiency in 1–5 W power stages. |
| Reverse Current (IR) | 325 µA typ. at 40 V - minimizes leakage-induced standby power loss in battery-powered systems. |
| Reverse Recovery Time (trr) | 3.1 ns - enables clean switching at ≥10 MHz frequencies, reducing EMI in high-speed SMPS designs. |
| Package Dimensions | 1.0 × 0.6 × 0.27 mm - fits 0402 footprint equivalents, allowing dense layout in wearables and ultra-thin displays. |
| Junction-to-Ambient Rth(j-a) | 70 K/W on ceramic PCB - enables 1.78 W total power dissipation at 25 °C ambient, supporting higher peak loads. |
Pinout & Package
DSN1006-2 (SOD993) is a leadless, ultra-thin surface-mount package with 2 terminals and a transparent top view; body dimensions are 1.0 mm × 0.6 mm × 0.27 mm. The cathode is marked by a bar on the top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Output terminal for rectified DC; connects to load or output capacitor; marking bar identifies this terminal. |
| 2 | Anode (A) | Input terminal for AC or switched input; ties to switch node or transformer secondary; provides thermal path via solder pad. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Suppresses edge breakdown during voltage transients, enhancing reliability in automotive and industrial surge environments. |
| Ultra-low VF (435 mV) | Reduces forward power loss to <0.44 W at 1 A, critical for thermal management in sealed enclosures. |
| Sub-300 µm height | Enables mechanical stacking with thin batteries or displays in smartphones and TWS earbuds. |
| Low IR (325 µA @ 40 V) | Limits no-load power drain in always-on circuits, extending battery life in IoT sensors and remote controls. |
| DSN1006-2 package | Offers 2× better thermal conductivity than comparable 0402 packages due to direct copper pad contact and minimal die attach voiding. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (520 mV typ.), larger SOD-523 package (1.6 × 0.8 mm), no guard ring. | Less suitable for high-frequency (>100 kHz) or thermally constrained layouts. | Select when legacy footprint compatibility outweighs efficiency and surge robustness requirements. |
| SS12 | Higher VR (20 V), lower IF(AV) (1.2 A), DO-214AC package (4.3 × 2.6 mm), VF = 500 mV. | Requires 5× more board area; unsuitable for ultra-thin or portable form factors. | Choose only if existing through-hole or large-SMD assembly infrastructure prohibits DSN1006-2 adoption. |
Compared with RB050M-30 and SS12, PMEG4010AESBYL delivers superior power density (1.0 × 0.6 mm), lowest VF among 40 V Schottkys in its class, and proven guard ring protection - making it optimal for next-generation portable and energy-sensitive embedded systems where thermal headroom and board space are tightly constrained.

FAQ
What is the maximum allowable solder point temperature for PMEG4010AESBYL during reflow?
The datasheet specifies a maximum solder point temperature (Tsp) of 145 °C for 20 kHz square-wave operation at 1 A average current. For DC operation, the absolute maximum Tsp is 150 °C. Exceeding these limits risks degradation of the Schottky junction and increased reverse leakage over time.
Can PMEG4010AESBYL be used in automotive applications?
No - PMEG4010AESBYL is not automotive-qualified. It lacks AEC-Q101 certification and has not undergone automotive-specific stress testing. Nexperia explicitly states non-automotive qualified products are unsuitable for safety-critical or life-support systems, including automotive ECUs or ADAS modules.
How does the guard ring improve reliability in real-world use?
The integrated guard ring mitigates electric field crowding at the silicon edge, preventing premature avalanche breakdown during voltage transients. In practice, this allows the device to survive 1 kV ESD events (IEC 61000-4-2) and 40 V reverse surges without parameter shift - eliminating need for external protection in many portable designs.
Is the DSN1006-2 package compatible with standard 0402 pick-and-place equipment?
Yes - DSN1006-2 shares identical X-Y footprint (1.0 × 0.6 mm) and tape-and-reel packaging (EIA-481 compliant) with industry-standard 0402 passives. Its 0.27 mm height requires fine-pitch nozzle calibration but is supported by modern placement machines with vision-assisted alignment.
