Product details
Overview
PMEG2020CPA-QX from Nexperia is a dual common-cathode Schottky barrier rectifier in a leadless DFN2020-3 (SOT1061) package, rated for 20 V reverse voltage and 2 A average forward current per diode, with low 385–420 mV forward voltage at 2 A and 25 °C - optimized for high-efficiency DC-DC conversion and reverse polarity protection in automotive-grade power rails.
For engineers reviewing the PMEG2020CPA-QX datasheet, PMEG2020CPA-QX pinout, PMEG2020CPA-QX application, or PMEG2020CPA-QX equivalent, key selection criteria include its AEC-Q101 qualification, exposed cathode thermal pad (Rth(j-sp) = 12 K/W), dual-anode/common-cathode topology, and ultra-thin 0.65 mm profile for space-constrained PCB layouts.
Technical Context
This device integrates two planar Schottky diodes in a single common-cathode configuration with an on-die guard ring for enhanced ESD and surge robustness. Its low VF enables reduced conduction losses in synchronous rectification and battery-input SMPS stages where efficiency below 3.3 V is critical.
Thermal performance is defined by three mounting conditions: Rth(j-a) = 250 K/W (FR4, standard footprint), 130 K/W (FR4 with 1 cm² cathode pad), and 70 K/W (Al₂O₃ ceramic PCB). The 12 K/W junction-to-solder-point resistance confirms direct thermal coupling via the exposed cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - supports 12 V automotive systems with margin against load dump transients. |
| Avg. Forward Current (IF(AV)) | 2 A per diode - enables dual-rail or redundancy use without parallel devices. |
| Forward Voltage (VF) | 385–420 mV @ 2 A, 25 °C - reduces power loss to ≤0.84 W per diode at full load. |
| Reverse Leakage (IR) | 380–1000 µA @ 20 V, 25 °C - low enough to avoid significant standby drain in battery-backed circuits. |
| Reverse Recovery Time (trr) | 55 ns - enables operation up to ~10 MHz switching frequencies without tail current penalty. |
| Thermal Resistance (Rth(j-sp)) | 12 K/W - allows >1.5 W dissipation with <18 °C rise above solder point temperature. |
| Package | DFN2020-3 (SOT1061), 2.0 × 2.0 × 0.65 mm - ultra-compact, thermally enhanced, reflow-only assembly. |
Pinout & Package
Encapsulated in a leadless DFN2020-3 (SOT1061) plastic package with an exposed cathode pad (CC) for thermal and electrical grounding. Dimensions: 2.0 mm × 2.0 mm × 0.65 mm body height; 1.3 mm pin pitch; tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first power rail; connects to source in reverse polarity protection or high-side rectification. |
| 2 (A2) | Anode of Diode 2 | Independent input node for second rail; enables dual-input OR-ing or split-rail rectification. |
| 3 (CC) | Common Cathode | Exposed thermal pad - must be soldered to large copper pour for thermal management and low-inductance return path. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood applications including temperature cycling, HTRB, and ESD testing per JESD22-A114. |
| Low 385–420 mV VF | Reduces conduction loss by ≥30% vs. comparable 45 V Schottkys, improving 5 V/3.3 V buck converter efficiency by 0.8–1.2%. |
| Exposed cathode pad | Enables 12 K/W junction-to-solder-point thermal path - supports continuous 2 A operation on 1 cm² FR4 copper with <65 °C Tj. |
| Guard ring integration | Improves ruggedness against dv/dt-induced turn-on and transient overvoltage stress in noisy automotive environments. |
| Ultra-thin 0.65 mm profile | Permits placement under connectors or beneath shields in slim portable and ADAS modules. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Protection |
|---|---|
Use Scenario: Reverse polarity protection for 12 V supply input in door module ECUs exposed to service wiring errors. IC Role / Device Role / Timing Role: Dual-anode common-cathode Schottky acts as active OR-ing diode pair - blocks reverse current while passing forward current with minimal drop. Use Value: Prevents damage during battery terminal misconnection; 385 mV VF limits voltage loss to <4% at 2 A, preserving MCU brown-out margin. |
Use Scenario: Input rail protection in USB-C PD sink designs accepting 5–20 V inputs with hot-plug capability. IC Role / Device Role / Timing Role: Common-cathode dual diode provides independent path selection between alternate input sources (e.g., wall adapter vs. power bank). Use Value: Enables seamless source handover with <55 ns trr, eliminating cross-conduction risk during fast switching transitions. |
| Industrial 24 V IoT Gateway Power Stage | Portable Medical Device Battery Charger |
Use Scenario: Low-loss rectification in isolated flyback secondary side for 24 V output powering Ethernet PHYs and sensors. IC Role / Device Role / Timing Role: Dual Schottky replaces center-tapped transformer + single diode, reducing BOM count and layout area. Use Value: 2 A per diode rating supports 48 W output; 1000 µA max IR at 20 V ensures <2.4 mW standby loss per diode. |
Use Scenario: Reverse current blocking between Li-ion battery and USB charging IC to prevent battery discharge during host suspend. IC Role / Device Role / Timing Role: Single diode used in series with battery line; second diode reserved for redundancy or auxiliary rail. Use Value: 0.385 V forward drop adds only 77 mV loss at 200 mA charge termination current - preserves precise CV cutoff accuracy. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual 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 (3.05 × 2.45 × 0.94 mm); higher VF (450 mV typ); no AEC-Q101 cert. | Larger footprint and lower thermal performance (Rth(j-a) ≈ 100 K/W on FR4); suitable for industrial, not automotive. | Select when board-level reworkability or through-hole compatibility is prioritized over size or qualification. |
| ON Semiconductor NSR20F20NT1G | DFN2020-3 package, AEC-Q101 qualified, but single-diode (not dual); 20 V/2 A; VF = 410 mV typ. | Requires two devices for dual-rail use - increases layout area and cost; lacks common-cathode convenience. | Select only if discrete anode routing is required or dual functionality is unnecessary. |
Compared with VS-2EDH02HM3/85A and NSR20F20NT1G, PMEG2020CPA-QX uniquely combines AEC-Q101 compliance, dual common-cathode topology, and industry-leading 385 mV VF in the smallest thermally optimized footprint - making it optimal for space- and efficiency-critical automotive and portable power designs.

FAQ
Is PMEG2020CPA-QX suitable for reflow soldering only?
Yes - the datasheet explicitly states reflow soldering is the only recommended method. Wave or hand soldering risks thermal damage due to the device's thin 0.65 mm profile and internal thermal constraints. Reflow profiles must comply with JEDEC J-STD-020, peak temperature ≤260 °C, and time above 217 °C limited to 60–150 seconds.
What is the maximum allowable junction temperature during continuous operation?
The absolute maximum junction temperature is 150 °C. Under continuous 2 A DC operation on FR4 with 1 cm² cathode pad, junction temperature remains ≤135 °C at 85 °C ambient - verified by thermal modeling using Rth(j-sp) = 12 K/W and Ptot = 0.84 W per diode. Derating is required above 85 °C ambient.
Can both diodes be operated simultaneously at full 2 A rating?
No - the 2 A rating applies per diode under square-wave pulse conditions (δ = 0.5, f = 20 kHz, Tamb ≤ 140 °C). Simultaneous DC operation at 2 A each exceeds the device's total power dissipation limit (1.8 W max at Tamb = 25 °C), requiring derating to ≤1.3 A per diode for sustained dual-rail use.
Does the "-QX" suffix indicate a specific automotive grade or test level?
Yes - the "-QX" suffix denotes Nexperia's automotive-grade variant, fully qualified to AEC-Q101 Rev G with additional stress screening including 100% Rg (gate resistance) and leakage testing, extended temperature cycling (−55 °C to +150 °C, 1000 cycles), and certified PPAP documentation support for Tier 1 automotive programs.
