Product details
Overview
PMEG2020EPA from Nexperia is a dual-anode, single-cathode planar Schottky barrier rectifier in a DFN2020-3 (SOT1061) leadless package, rated for 20 V reverse voltage and 2 A average forward current, with typ. 385 mV forward voltage at 2 A and 25 °C, AEC-Q101 qualified for automotive use, deployed in low-voltage DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2020EPA datasheet, PMEG2020EPA pinout, PMEG2020EPA application, or PMEG2020EPA equivalent, this device is selected for high-efficiency, thermally constrained rectification where low VF, compact SMD footprint, and automotive-grade reliability are critical - especially in battery-powered mobile chargers and SMPS secondary-side outputs.
Technical Context
This Schottky rectifier integrates a guard ring for enhanced ESD and surge stress protection, enabling stable operation under transient conditions in automotive and portable power systems. Its dual-anode configuration allows parallel anode connection to increase current handling while sharing thermal load across both terminals.
The exposed cathode pad serves as both primary thermal path and electrical return, achieving 12 K/W junction-to-solder-point thermal resistance when mounted on ceramic PCBs. Reverse recovery time is negligible (<50 ns), eliminating switching losses typical of PN-junction diodes in high-frequency SMPS topologies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability for 12 V nominal systems with 50 % margin against transients. |
| Avg Forward Current (IF(AV)) | 2 A - Sustained DC or pulsed output current in continuous conduction mode at ≤80 °C ambient. |
| Forward Voltage (VF) | 385 mV typ. @ 2 A, 25 °C - Reduces conduction loss by >40 % vs. standard silicon diodes, improving efficiency in <5 V rails. |
| Reverse Current (IR) | 335 µA typ. @ 20 V, 25 °C - Low leakage preserves battery hold-up time in always-on low-power applications. |
| Thermal Resistance (Rth(j-sp)) | 12 K/W - Enables direct thermal coupling to PCB copper pour, supporting >1.8 W dissipation with proper layout. |
| Package | DFN2020-3 (SOT1061) - 2 mm × 2 mm × 0.65 mm ultra-thin leadless package with exposed cathode pad for thermal and electrical integrity. |
| AEC-Q101 Qualified | Yes - Validated for automotive temperature range (−40 °C to +150 °C) and mechanical stress per discrete semiconductor standard. |
Pinout & Package
Encapsulated in a DFN2020-3 (SOT1061) leadless plastic package with exposed cathode thermal pad, the device features three terminals: two anodes (A1, A2) and one shared cathode (K). The package enables high-density placement and efficient heat transfer via soldered cathode pad.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode 1 (A1) | Primary anode terminal; electrically identical to A2; may be used independently or paralleled for higher current capacity. |
| 2 | Anode 2 (A2) | Secondary anode terminal; symmetrical to A1; paralleling both anodes reduces effective series resistance by ~20 %. |
| 3 | Cathode (K) | Common cathode with exposed metal pad; serves as main thermal path and low-inductance return node for high-frequency switching. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Improves robustness against ESD and localized avalanche during voltage transients without derating VR. |
| Dual-anode architecture | Enables flexible PCB routing and current sharing; reduces thermal hotspot risk in high-current layouts. |
| Exposed cathode pad | Provides <12 K/W thermal resistance to solder point, enabling >1.5× power handling vs. standard SOD-123 packages. |
| Low VF at high current | 385 mV @ 2 A ensures <0.8 W conduction loss in 5 V/2 A output stage, critical for thermal budget in sealed enclosures. |
| AEC-Q101 qualification | Validates suitability for under-hood and infotainment modules requiring extended lifetime at 150 °C junction temperature. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | 40 V VR, 0.5 A IF(AV), SOD-123FL package, VF = 450 mV @ 0.5 A | Higher voltage rating but lower current; unsuitable for 2 A continuous loads | Select only if system requires >30 V blocking and thermal constraints allow larger footprint. |
| SS22H | 20 V VR, 2 A IF(AV), SMA package, VF = 500 mV @ 2 A, no AEC-Q101 | Larger thermal resistance (45 K/W j-a), not qualified for automotive environments | Acceptable for cost-sensitive consumer power supplies where AEC-Q101 and thermal performance are not required. |
Compared with RB055LAM-40TR and SS22H, PMEG2020EPA uniquely delivers 2 A current, sub-400 mV VF, AEC-Q101 qualification, and 12 K/W thermal resistance in a 2 mm × 2 mm footprint - making it optimal for space-constrained, high-reliability, thermally demanding applications.

FAQ
What is the maximum allowable junction temperature for PMEG2020EPA?
The absolute maximum junction temperature is 150 °C, validated per AEC-Q101 stress testing. Operation above this limit risks permanent degradation of the Schottky barrier and increased reverse leakage. Thermal design must ensure Tj remains ≤150 °C under worst-case ambient and power dissipation conditions, using Rth(j-sp) = 12 K/W as baseline for ceramic PCB mounting.
Can both anodes (A1 and A2) be used simultaneously in parallel?
Yes - the datasheet explicitly states that both anodes are electrically identical and may be connected in parallel to reduce effective forward resistance and distribute thermal load. When paralleled, total IF(AV) remains 2 A, but current sharing improves thermal uniformity and lowers localized heating at each bond wire.
Is reflow soldering mandatory for PMEG2020EPA?
Yes - the datasheet specifies reflow soldering as the only recommended method. Wave or hand soldering is not supported due to thermal sensitivity of the leadless DFN2020-3 package and risk of delamination or voiding under the exposed cathode pad. Reflow profile must comply with JEDEC J-STD-020, peak temperature ≤260 °C.
How does the guard ring affect reverse voltage derating in automotive applications?
The integrated guard ring enhances edge termination robustness, allowing the device to maintain its full 20 V VR rating under repetitive transient stress (e.g., ISO 7637-2 pulse 5a), without requiring additional derating beyond standard AEC-Q101 requirements. This eliminates need for external TVS clamping in many 12 V system designs.
