Product details
Overview
PMEG2010EPASX from Nexperia is a 20 V, 1 A low forward voltage Schottky barrier rectifier in a DFN2020D-3 (SOT1061D) leadless package, featuring integrated guard ring stress protection, 320–375 mV VF at 1 A, ≤1900 µA IR at 20 V, and AEC-Q101 qualification for automotive-grade reliability in space-constrained DC/DC and SMPS applications.
For engineers reviewing the PMEG2010EPASX datasheet, PMEG2010EPASX pinout, PMEG2010EPASX application, or PMEG2010EPASX equivalent, this device delivers verified low-VF rectification with thermal performance validated on FR4 and ceramic PCBs, AOI-compatible side pads, and cathode-exposed thermal pad for junction-to-solder-point Rth(j-sp) as low as 12 K/W.
Technical Context
This MEGA Schottky rectifier uses a planar silicon structure with integrated guard ring to suppress edge breakdown and improve surge robustness under repetitive and non-repetitive peak currents up to 7 A (IFRM) and 17 A (IFSM). Its low reverse recovery time (trr = 50 ns) and low diode capacitance (Cd = 65 pF at VR = 10 V) support high-frequency switching in compact power converters.
The dual-anode configuration (Pins 1 & 2) enables parallel current handling while maintaining low thermal resistance - Rth(j-a) is 70 K/W on ceramic PCB and 130 K/W on FR4 with 1 cm² cathode pad - enabling stable operation up to Tj = 150 °C with average forward current derated per ambient and solder point temperature curves.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 1 A | 320–375 mV - Enables <0.4 W conduction loss at full load, critical for >90% efficiency in portable DC/DC stages. |
| VR | 20 V - Rated for 12 V nominal input systems with 50% margin against transients and ripple overshoot. |
| IF(AV) | 1 A - Sustained DC output capability with thermal design validated across FR4 and Al₂O₃ substrates. |
| IR @ 20 V | 335–1900 µA - Low leakage preserves battery life in always-on mobile charger and LED backlight circuits. |
| trr | 50 ns - Minimizes switching losses and EMI in 500 kHz–1 MHz SMPS topologies without snubbers. |
| Rth(j-sp) | 12 K/W - Direct thermal path from junction to solder point enables efficient heat extraction via cathode pad. |
| AEC-Q101 | Qualified - Validated for automotive cabin electronics, infotainment power rails, and ADAS auxiliary supplies. |
Pinout & Package
DFN2020D-3 (SOT1061D) is an ultra-thin 2.0 × 2.0 × 0.65 mm leadless package with exposed cathode thermal pad (Pin 3) and visible, solderable side pads on Pins 1 and 2 for AOI compatibility and mechanical robustness.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode connection; electrically tied to Pin 2 for parallel current sharing and reduced trace inductance. |
| 2 | Anode | Secondary anode; dual-anode layout lowers effective series resistance and improves thermal distribution. |
| 3 | Cathode | Exposed copper thermal pad - serves as main heat sink and return path; requires full-solder coverage for Rth(j-sp) = 12 K/W. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge avalanche, enabling stable 20 V reverse blocking under thermal and voltage stress in automotive environments. |
| Exposed cathode pad | Provides dual function: low-inductance electrical return and direct thermal conduction path to PCB plane. |
| Side-wettable flanks | Enables automated optical inspection (AOI) of solder joint integrity without X-ray, reducing manufacturing QA cost. |
| Ultra-thin profile (0.65 mm) | Supports <1.0 mm total board height in slim mobile devices and wearables where Z-space is constrained. |
| Low Cd (65 pF @ 10 V) | Reduces capacitive switching loss and improves light-load efficiency in adaptive frequency DC/DC controllers. |
Applications
| Mobile Battery Charger | LED Backlight Driver |
|---|---|
Use Scenario: Input rectification in single-cell Li-ion USB-powered chargers with synchronous buck topology. IC Role / Device Role / Timing Role: Low-VF freewheeling diode replacing MOSFET body diode to reduce conduction loss during low-duty-cycle phases.

IC Role / Device Role / Timing Role: Cathode-grounded clamp diode absorbing inductive kickback from boost inductor during switch-off. Use Value: 50 ns trr prevents voltage overshoot beyond LED string rating; 1900 µA max IR avoids standby current drain. |
| Automotive Infotainment PSU | Industrial SMPS Auxiliary Rail |
Use Scenario: 12 V input rectification and reverse protection in head-unit DC/DC modules operating at −40 °C to +105 °C ambient. IC Role / Device Role / Timing Role: AEC-Q101-qualified Schottky providing primary input protection and freewheeling in buck pre-regulator stage.

IC Role / Device Role / Timing Role: High-efficiency secondary-side rectifier delivering 1 A at 5 V/3.3 V with minimal heatsink requirement. Use Value: Rth(j-a) = 70 K/W on ceramic PCB allows full 1 A load without forced air, reducing system BOM cost. |
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 (450 mV @ 1 A), same 20 V VR, larger SOD-123FL package (3.5 × 1.6 mm). | Lacks AEC-Q101 qualification and side-wettable flanks; unsuitable for AOI or automotive use. | Select only for cost-sensitive non-automotive consumer designs where board area is not constrained. |
| SS12 | Same VF range (320–370 mV), but DO-214AC (SMA) package (4.5 × 2.7 mm), no guard ring, IR = 500 µA @ 20 V. | No thermal pad; Rth(j-a) ≈ 150 K/W limits continuous current to ~0.6 A on FR4. | Choose when legacy through-hole or larger SMD footprint is acceptable and AEC-Q101 is not required. |
Compared with RB050M-30 and SS12, PMEG2010EPASX provides superior thermal performance (Rth(j-sp) = 12 K/W), automotive qualification, and 40% smaller footprint - making it optimal for space- and reliability-critical 1 A rectification in modern embedded power systems.

FAQ
What is the maximum continuous forward current for PMEG2010EPASX at 85 °C ambient on FR4 PCB?
At Tamb = 85 °C on standard FR4 PCB (single-sided copper, tin-plated), the device supports 1.0 A average forward current (IF(AV)) with δ = 0.5 duty cycle and f = 20 kHz square wave, per Figure 10. Derating begins above 85 °C ambient, reaching 0.7 A at 125 °C.
Does PMEG2010EPASX require special PCB layout for thermal performance?
Yes - optimal thermal performance requires full-solder coverage of the exposed cathode pad (Pin 3) with ≥1 cm² copper pour on inner or outer layer. The datasheet specifies Rth(j-sp) = 12 K/W only when using this 1 cm² mounting pad on FR4; omitting it degrades Rth(j-a) to 130 K/W.
Is the dual-anode configuration electrically independent or internally bonded?
Pins 1 and 2 are internally shorted anodes - confirmed in Table 2 (Pinning information) and Limiting Values section [2]: "Both anode pins connected." This configuration reduces effective series resistance and distributes current, but does not allow independent circuit routing.
Can PMEG2010EPASX replace standard SOD-123 Schottky diodes in existing layouts?
No - its DFN2020D-3 (2.0 × 2.0 mm) footprint is incompatible with SOD-123 (3.5 × 1.6 mm). Pad layout, stencil aperture, and reflow profile must be redesigned. However, its side-wettable flanks enable reliable AOI verification post-solder, unlike traditional SOD packages.
