Product details
Overview
PMEG2020CPAS-QX from Nexperia is a dual common-cathode Schottky barrier rectifier optimized for low-voltage, high-efficiency power conversion. It delivers 2 A average forward current per diode at ≤420 mV forward voltage (IF = 2 A, Tj = 25 °C), with 20 V reverse voltage rating and AEC-Q101 qualification - deployed in automotive DC-DC converters and mobile battery chargers.
For engineers reviewing the PMEG2020CPAS-QX datasheet, PMEG2020CPAS-QX pinout, PMEG2020CPAS-QX application, or PMEG2020CPAS-QX equivalent, key selection criteria include its ultra-thin DFN2020D-3 package with exposed cathode pad, low thermal resistance (Rth(j-sp) = 12 K/W), and pulsed reverse current <1000 µA at VR = 20 V.
Technical Context
This dual Schottky rectifier uses planar MEGA technology with an integrated guard ring for robust stress protection. Its common-cathode configuration enables compact dual-diode operation in space-constrained layouts while maintaining independent anode control.
The device operates with negligible reverse recovery time (trr = 55 ns typical) and low junction capacitance (Cd = 65 pF at VR = 10 V, f = 1 MHz), supporting high-frequency switching up to 20 kHz in SMPS and freewheeling topologies without significant switching loss penalties.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 2 A | 385–420 mV - Enables ≥92% efficiency in 3.3 V/5 V output DC-DC stages by minimizing conduction loss. |
| VR | 20 V - Rated for 12 V automotive rail systems with margin for load-dump transients. |
| IF(AV) per diode | 2 A - Sustains continuous output current in dual-path 1 A loads or single-path 2 A applications. |
| IR @ 20 V | 380–1000 µA - Low leakage preserves battery runtime in always-on mobile charging circuits. |
| trr | 55 ns - Eliminates snubber requirements in 500 kHz–1 MHz synchronous rectifier designs. |
| Rth(j-sp) | 12 K/W - Direct thermal path from junction to solder point enables >1.5 W dissipation on FR4 with 1 cm² cathode pad. |
| Package | DFN2020D-3 (SOT1061D), 2.0 × 2.0 × 0.65 mm - Ultra-thin footprint reduces PCB area by 40% vs. SO-8. |
Pinout & Package
Encapsulated in a leadless DFN2020D-3 (SOT1061D) package with visible and solderable side pads and an exposed cathode thermal pad (Pin 3). The ultra-thin 0.65 mm profile supports co-planarity in fine-pitch mobile assemblies.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode Diode 1 (A1) | Input node for first rectification path; connects to switching node in buck converter high-side leg. |
| 2 | Anode Diode 2 (A2) | Independent input node for second rectification path; enables dual-output or redundancy schemes. |
| 3 | Common Cathode (K) | Shared output/return node with exposed copper pad - primary thermal and electrical return path to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive under-hood temperature cycling (−40 °C to +150 °C) and mechanical shock. |
| Exposed cathode pad | Reduces Rth(j-a) to 70 K/W on ceramic PCB - enables 1.8 W continuous dissipation without heatsink. |
| Guard ring integration | Prevents edge breakdown under high dv/dt stress in fast-switching SMPS, improving long-term reliability. |
| AOI-compatible side pads | Solderable side terminations allow 100% automated optical inspection of solder joint integrity post-reflow. |
| Low VF temperature stability | VF drift <1.2 mV/°C from −40 °C to +125 °C - maintains regulation accuracy across wide ambient ranges. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | Single diode, 40 V VR, 0.5 A IF(AV), SOD-123FL package | Lacks dual configuration and AEC-Q101 qualification; unsuitable for automotive or dual-load use cases. | Select only for cost-sensitive, non-automotive 5 V systems requiring <0.5 A per path. |
| SS22-AU | Dual common-cathode, 20 V VR, 2 A IF(AV), but VF = 500 mV min at 2 A and no AEC-Q101 rating | Higher conduction loss increases thermal stress in enclosed mobile designs; not validated for automotive temperature cycling. | Acceptable for industrial consumer chargers where AEC-Q101 is not mandated and 80 mV higher VF is tolerable. |
Compared with RB055LAM-40TR and SS22-AU, PMEG2020CPAS-QX uniquely combines AEC-Q101 compliance, 420 mV VF ceiling, and dual-diode DFN packaging - making it the only option qualified for thermally constrained automotive DC-DC and dual-port mobile charging where reliability and efficiency are jointly critical.

FAQ
Is PMEG2020CPAS-QX suitable for reflow soldering on standard FR4 PCBs?
Yes - the DFN2020D-3 package is qualified for lead-free reflow per JEDEC J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds. The exposed cathode pad requires full-surface solder paste coverage and a minimum 1 cm² copper pour for optimal thermal performance per Nexperia's SOT1061D footprint guidelines.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is 150 °C. Under continuous DC operation on FR4 with 1 cm² cathode pad, the device sustains 2 A per diode up to Tamb = 85 °C. Derating begins above this ambient, reaching 0 A at Tamb = 125 °C - values confirmed in Figure 11 of the official datasheet.
Does PMEG2020CPAS-QX support bidirectional current flow?
No - it is a unidirectional Schottky rectifier. Current flows only from anode (Pins 1 or 2) to common cathode (Pin 3). Reverse conduction is blocked above the rated 20 V VR, with leakage limited to ≤1000 µA at 20 V and 25 °C per datasheet Table 7.
How does the guard ring improve reliability in automotive environments?
The integrated guard ring mitigates electric field crowding at the silicon edge during high dv/dt transients (e.g., load dump or ignition noise), preventing premature avalanche breakdown. This extends operational lifetime under repeated thermal and voltage stress - a requirement verified in AEC-Q101 HTRB and AC-H3TRB testing.
