Product details
Overview
PMEG2020EPA-QX from Nexperia is a dual-anode, single-cathode planar Schottky barrier rectifier in a leadless DFN2020-3 (SOT1061) package, rated for 20 V reverse voltage and 2 A average forward current at Tsp ≤ 140 °C. It delivers low 385 mV typical forward voltage at 2 A/25 °C, features an exposed cathode thermal pad for enhanced heat dissipation, and is AEC-Q101 qualified for automotive power rail protection and DC-DC conversion.
For engineers reviewing the PMEG2020EPA-QX datasheet, PMEG2020EPA-QX pinout, PMEG2020EPA-QX application, or PMEG2020EPA-QX equivalent, key selection criteria include its 2 A continuous current capability on FR4 with 1 cm² cathode pad, 50 ns reverse recovery time, 17 A non-repetitive peak forward surge rating, and thermal resistance of 12 K/W junction-to-solder-point - critical for high-density power management in automotive ECUs and portable chargers.
Technical Context
This Schottky rectifier integrates a guard ring for mechanical and electrical stress protection, enabling robust operation under transient overvoltage conditions in 12 V automotive systems. Its dual-anode configuration allows parallel conduction paths while sharing a common cathode thermal sink, supporting redundancy or current-sharing topologies without external bus bars.
The device operates with zero minority-carrier storage, eliminating reverse recovery charge (Qrr) and associated switching losses. Its 65 pF diode capacitance at 10 V reverse bias and 175 pF at 1 V enable fast switching in high-frequency SMPS (>1 MHz), while the 1.8 W total power dissipation limit at 25 °C ambient reflects optimized thermal coupling to PCB copper.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking voltage before breakdown; suitable for 12 V nominal automotive rails with 100 % margin against load dump transients. |
| Average Forward Current (IF(AV)) | 2 A - Sustained DC or pulsed current capability when mounted on FR4 with 1 cm² cathode pad and Tsp ≤ 140 °C. |
| Forward Voltage (VF) | 385 mV typ. @ 2 A, 25 °C - Low conduction loss reduces power dissipation by >30 % vs. standard silicon diodes in 5–12 V output stages. |
| Reverse Current (IR) | 335 µA typ. @ 20 V, 25 °C - Minimal leakage preserves battery standby time in always-on vehicle modules. |
| Reverse Recovery Time (trr) | 50 ns - Near-instantaneous turn-off enables efficient operation in synchronous rectification and high-frequency flyback converters. |
| Junction-to-Solder-Point Rth | 12 K/W - Direct thermal path from die to PCB solder point enables compact thermal design without heatsinks in space-constrained modules. |
| Package | DFN2020-3 (SOT1061) - 2 mm × 2 mm × 0.65 mm leadless package with exposed cathode pad; supports reflow-only assembly and IPC Class 3 reliability. |
Pinout & Package
Encapsulated in a thermally enhanced DFN2020-3 (SOT1061) plastic package with an exposed cathode thermal pad on the bottom side. The package measures 2.0 mm × 2.0 mm × 0.65 mm and uses a 1.3 mm pin pitch. Reflow soldering is the only recommended assembly method.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode 1 | Primary current input terminal; electrically isolated from A2 but shares same cathode node; supports dual-input redundancy or split-current routing. |
| 2 (A2) | Anode 2 | Secondary current input terminal; identical electrical characteristics to A1; both anodes must be connected in parallel for full 2 A rating per datasheet limiting values. |
| 3 (K) | Cathode | Common output and thermal interface; exposed copper pad on underside provides low-inductance return path and primary heat extraction route to PCB. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing - enables use in engine control, ADAS, and body electronics without additional qualification. |
| Integrated guard ring | Prevents edge breakdown under mechanical stress or contamination; improves long-term stability in humid or vibration-prone environments like under-hood applications. |
| Exposed cathode thermal pad | Reduces Rth(j-sp) to 12 K/W - allows 2 A continuous operation on standard FR4 with minimal copper area, eliminating need for thermal vias or external heatsinks. |
| Low 385 mV VF at 2 A | Minimizes I²R losses in high-current paths; enables >95 % efficiency in 5 V/2 A buck converter outputs where diode conduction dominates loss budget. |
| 50 ns trr and zero Qrr | Eliminates reverse recovery spikes and EMI in high-frequency switching; simplifies EMI filter design in USB-C PD and wireless charging receivers. |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-2EDH02HM3/85A | Same 20 V/2 A rating but TO-277 package (larger, leads required); higher VF = 450 mV typ.; no AEC-Q101 qualification. | Requires through-hole or larger SMD footprint; unsuitable for automated reflow-only lines or automotive production. | Select only if legacy TO-277 compatibility or higher surge rating (25 A IFSM) is prioritized over size and qualification. |
| ON Semiconductor NSR20F20NT1G | DFN2020-3 package, AEC-Q101 qualified, but 450 mV VF typ. @ 2 A and 1000 µA IR @ 20 V. | Higher conduction loss and leakage reduce efficiency in battery-powered applications; same thermal pad layout enables drop-in PCB replacement. | Acceptable for cost-sensitive industrial designs where 5 % efficiency penalty and 3× leakage are tolerable. |
Compared with VS-2EDH02HM3/85A and NSR20F20NT1G, PMEG2020EPA-QX offers the lowest forward voltage and smallest qualified footprint, making it optimal for space-constrained, high-efficiency automotive and portable power systems where thermal performance and qualification rigor are mandatory.

FAQ
Is PMEG2020EPA-QX compatible with lead-free reflow soldering processes?
Yes. The device is qualified for reflow soldering only, per datasheet Section 13. It supports JEDEC J-STD-020 moisture sensitivity level 1 and withstands peak temperatures up to 260 °C for 30 seconds. No wave or hand-soldering is recommended due to thermal pad geometry and internal stress risks.
Can both anode pins (A1 and A2) be used independently in separate circuits?
No. A1 and A2 are electrically isolated but share the same cathode (K) and die substrate. Using them in separate circuits creates unintended current paths and violates the absolute maximum ratings. They must be connected in parallel to achieve the rated 2 A IF(AV), as confirmed in Table 5 footnote [2].
What is the minimum recommended copper area for the cathode thermal pad on FR4?
The datasheet specifies 1 cm² of single-sided, tin-plated copper for the cathode pad to achieve the 960 mW Ptot rating and 130 K/W Rth(j-a). Reducing pad area below this de-rates IF(AV) nonlinearly - e.g., 0.5 cm² limits continuous current to ~1.3 A at 25 °C ambient per Figure 10.
Does PMEG2020EPA-QX have a specified reverse recovery charge (Qrr)?
No. As a Schottky barrier diode, it exhibits majority-carrier conduction with no minority-carrier storage. Therefore, Qrr is effectively zero - a key differentiator from PN-junction diodes. This eliminates reverse recovery loss and associated EMI, confirmed by the absence of Qrr in Tables 7 and 8 of the datasheet.
