Product details
Overview
PMEG3020EPASX from Nexperia is a 30 V, 2 A low forward voltage Schottky barrier rectifier in a DFN2020D-3 (SOT1061D) ultra-thin leadless package, featuring integrated guard ring stress protection, exposed cathode thermal pad, and AEC-Q101 qualification for automotive reliability. It delivers VF = 410–470 mV at IF = 2 A and IR ≤ 2500 µA at VR = 30 V, enabling high-efficiency DC/DC conversion in space-constrained mobile power systems.
For engineers reviewing the PMEG3020EPASX datasheet, PMEG3020EPASX pinout, PMEG3020EPASX application, or PMEG3020EPASX equivalent, key selection criteria include its 470 mV max forward voltage, dual-anode thermal design, 12 K/W junction-to-solder-point thermal resistance, and suitability for reverse polarity protection and battery charger circuits requiring AEC-Q101 compliance.
Technical Context
This MEGA Schottky rectifier uses planar silicon construction with an integrated guard ring to suppress edge breakdown under transient stress, ensuring stable operation up to 150 °C junction temperature. Its low VF stems from optimized metal-semiconductor interface engineering rather than barrier height reduction alone.
The DFN2020D-3 package places both anode terminals on one side and the large-area cathode pad on the opposite side-enabling simultaneous thermal conduction and electrical current handling via the exposed copper tab. This architecture supports pulsed forward currents up to 17 A (IFSM) and average dissipation of 1800 mW on ceramic PCBs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ IF = 2 A | 410–470 mV - Enables <100 mW conduction loss per diode in 2 A load paths, critical for portable device efficiency. |
| VR | 30 V - Rated for 24 V nominal automotive and industrial bus applications with margin for transients. |
| IF(AV) | 2 A - Sustained DC or square-wave current capability at Tsp ≤ 140 °C, validated on FR4 and ceramic PCBs. |
| IR @ VR = 30 V | 435–2500 µA - Low leakage preserves battery standby time in reverse-polarity protection circuits. |
| trr | 4 ns - Near-zero reverse recovery minimizes switching losses and EMI in high-frequency SMPS freewheeling. |
| Rth(j-sp) | 12 K/W - Direct thermal path from junction to solder point enables compact thermal design without external heatsinks. |
| AEC-Q101 | Qualified - Meets automotive-grade stress testing for temperature cycling, HTRB, and ESD, supporting under-hood use. |
Pinout & Package
Encapsulated in the ultra-thin DFN2020D-3 (SOT1061D) package: 2 × 2 × 0.65 mm body, no leads, visible and solderable side pads, and exposed cathode thermal pad on bottom surface.
| 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 terminal; used with Pin 1 to distribute 2 A average current and improve thermal spreading. |
| 3 | Cathode | Exposed copper thermal pad - serves as main current return path and primary heat sink interface to PCB copper. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Prevents premature edge breakdown under voltage surge or mechanical stress, extending lifetime in automotive environments. |
| Exposed cathode pad | Provides 12 K/W junction-to-solder-point thermal resistance-enabling >1.8 W dissipation on standard FR4 with 1 cm² copper pad. |
| Leadless DFN2020D-3 | Reduces PCB footprint by 60% vs. SOD-123; supports AOI inspection and fine-pitch automated assembly for mobile PCBs. |
| Low VF / low IR trade-off | 470 mV max VF at 2 A with only 2.5 mA max IR at 30 V-optimized for high-efficiency, low-leakage DC/DC stages. |
| AEC-Q101 qualification | Validated for automotive temperature cycling (−40 °C to +125 °C), HTRB (1000 h @ 150 °C), and ESD (HBM ≥ 2 kV). |
Applications
| Mobile Battery Charger | Automotive Reverse Polarity Protection |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-30TR | Higher VF (520 mV typ @ 2 A), same 30 V VR, SOD-523 package (0.6 × 0.3 mm), no exposed thermal pad. | Limited to <0.5 A continuous due to higher thermal resistance (Rth(j-a) ≈ 400 K/W); unsuitable for automotive or high-power mobile use. | Select only for ultra-low-cost, sub-500 mA consumer wearables where board space is more critical than thermal performance. |
| SS32HE3_A/H | Same 30 V/2 A rating, VF = 500 mV max @ 2 A, SMA package (4.5 × 2.7 mm), Rth(j-a) = 65 K/W on FR4. | Larger footprint and higher VF increase conduction loss and require larger PCB area-less optimal for thin mobile designs. | Prefer when legacy SMA footprint compatibility is required and thermal budget allows 100+ mV higher drop. |
Compared with RB055LAM-30TR and SS32HE3_A/H, PMEG3020EPASX offers the lowest VF (470 mV max), best thermal performance (12 K/W j-sp), and smallest footprint (2 × 2 mm), making it the optimal choice for thermally constrained, high-efficiency automotive and mobile power designs.

FAQ
What is the maximum allowable solder point temperature for PMEG3020EPASX during reflow?
The absolute maximum solder point temperature (Tsp) is 140 °C for δ = 0.5 duty cycle at 20 kHz, and 135 °C for DC operation. Exceeding these limits risks delamination or intermetallic degradation. Reflow profiles must follow Nexperia's SOT1061D footprint guidelines with peak temperature ≤ 260 °C for ≤ 30 seconds.
Can Pins 1 and 2 be used independently, or must they be shorted externally?
Pins 1 and 2 are internally connected anodes and must be routed together to a common net. Using them separately violates the device's thermal and current-sharing design-separate routing increases resistance imbalance and localized heating, risking premature failure at rated current.
How does the guard ring affect reverse voltage derating in automotive applications?
The integrated guard ring maintains stable 30 V VR rating across temperature and humidity without additional derating. Unlike conventional Schottkys, it prevents edge-initiated avalanche under transient overvoltage (e.g., load dump), enabling direct use in 24 V systems without external TVS clamping.
Is the cathode pad electrically isolated from the internal die substrate?
No-the cathode pad is the direct metallurgical extension of the die's cathode contact and forms the primary current return path. It must be connected to system ground or the negative rail; floating or insulated mounting degrades thermal performance and may cause thermal runaway under high current.
