Product details
Overview
PMEG2020EPAS-QX from Nexperia is a 20 V, 2 A AEC-Q101-qualified MEGA Schottky barrier rectifier in DFN2020D-3 (SOT1061D) package, featuring low 385–420 mV forward voltage at 2 A, ≤1900 µA reverse leakage at 20 V, and integrated guard ring for stress protection - deployed in automotive-grade DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2020EPAS-QX datasheet, PMEG2020EPAS-QX pinout, PMEG2020EPAS-QX application, or PMEG2020EPAS-QX equivalent, key selection criteria include forward voltage drop under pulsed 2 A load, thermal resistance to solder point (12 K/W), AEC-Q101 qualification status, and dual-anode cathode-tab layout for high-current PCB routing.
Technical Context
This Schottky diode uses planar MEGA technology with an integrated guard ring to suppress edge breakdown and improve surge robustness. Its ultra-thin DFN2020D-3 package features exposed cathode pad for direct thermal and electrical connection to PCB copper.
It operates with zero reverse recovery time (trr < 50 ns), enabling high-frequency switching in SMPS and free-wheeling paths. The dual-anode configuration (Pins 1 & 2) supports parallel current handling while maintaining low VF across temperature (−40 °C to 150 °C junction).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 2 A | 385–420 mV - Enables ≥95% efficiency in 3.3–5 V output DC-DC stages at full load |

| IF(AV) | 2 A - Sustained DC current capability on FR4 PCB with 1 cm² cathode pad |
| IR @ 20 V | 335–1900 µA - Low leakage preserves battery standby life in always-on modules |
| trr | < 50 ns - Eliminates switching losses in >500 kHz buck converters |
| Rth(j-sp) | 12 K/W - Direct thermal path from junction to solder point enables 1.8 W dissipation at Tsp = 135 °C |
| Package | DFN2020D-3 (SOT1061D), 2.0 × 2.0 × 0.65 mm - Ultra-thin footprint saves space in slim mobile and ADAS modules |
Pinout & Package
DFN2020D-3 (SOT1061D) is a leadless, thermally enhanced ultra-thin plastic package with visible and solderable side pads and an exposed cathode thermal pad on the bottom surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | Primary anode terminal; electrically and thermally tied to Pin 2 |

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, 5 A IF(AV), larger SOD-123FL package (3.5 × 1.6 × 1.0 mm) | Higher voltage margin but 2.5× larger footprint and 2.7× higher VF (1.05 V @ 5 A) | Select only if system requires >25 V transient tolerance and board space permits larger device |
| SS22H | 20 V VR, 2 A IF(AV), SMA package (4.5 × 2.7 × 2.1 mm), no AEC-Q101 qualification | Lacks automotive qualification and has 550 mV VF - unsuitable for thermally constrained modules | Acceptable for cost-sensitive industrial prototypes where AEC-Q101 is not mandated |
Compared with RB055LAM-40TR and SS22H, PMEG2020EPAS-QX delivers lowest VF in smallest footprint with certified automotive reliability - making it optimal for space- and efficiency-critical ADAS and body electronics designs.

FAQ
What is the maximum allowable solder point temperature for PMEG2020EPAS-QX?
The absolute maximum solder point temperature (Tsp) is 140 °C under square-wave conditions with 50% duty cycle, and 135 °C for continuous DC operation. Exceeding these limits risks degradation of the die attach and interconnect integrity, especially during reflow or repair cycles.
Does PMEG2020EPAS-QX support bidirectional current flow?
No - PMEG2020EPAS-QX is a unidirectional Schottky rectifier. It conducts only from anode (Pins 1 & 2) to cathode (Pin 3). Reverse conduction is blocked up to 20 V, with leakage current remaining below 1900 µA at rated VR and 25 °C.
How does the dual-anode configuration affect PCB layout?
The dual-anode design (Pins 1 & 2) must be routed with equal trace length and width to ensure balanced current sharing. Both pins connect internally to the same die region, so asymmetry causes localized heating and reduces effective current capacity below 2 A.
Is the exposed cathode pad required to be soldered to PCB copper?
Yes - the exposed cathode pad (Pin 3) must be fully soldered to a minimum 1 cm² copper area for thermal performance. Without this connection, Rth(j-a) degrades from 70 K/W to 250 K/W, limiting average current to ≤0.6 A at Tamb = 80 °C.
