Product details
Overview
PMEG3020CPA-QX from Nexperia is a dual common-cathode Schottky barrier rectifier in a leadless DFN2020-3 (SOT1061) package, rated for 30 V reverse voltage and 2 A average forward current per diode, with low 410–440 mV forward voltage at 2 A and 25 °C junction temperature. It integrates a guard ring for stress protection and features an exposed cathode pad for enhanced thermal dissipation, targeting high-efficiency DC-DC conversion and automotive-grade reverse polarity protection.
For engineers reviewing the PMEG3020CPA-QX datasheet, PMEG3020CPA-QX pinout, PMEG3020CPA-QX application, or PMEG3020CPA-QX equivalent, key selection criteria include its AEC-Q101 qualification, dual-diode common-cathode topology, 12 K/W junction-to-solder-point thermal resistance, and low VF performance under 2 A continuous load - critical for space-constrained, thermally demanding power rails.
Technical Context
This device implements two planar Schottky diodes sharing a single cathode terminal, enabling compact dual-path rectification or redundancy without external interconnection. Its guard ring structure improves ruggedness against transient overvoltage and ESD stress, while the ultra-thin 0.65 mm profile supports high-density PCB layouts.
The SOT1061 package uses copper-exposed cathode pad soldering to maximize heat transfer to the PCB, achieving 70 K/W Rth(j-a) on ceramic substrate and 130 K/W on FR4 with extended cathode pad - directly supporting sustained 2 A operation in ambient temperatures up to 75 °C under defined pulse conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - defines maximum blocking capability before breakdown; suitable for 24 V automotive and industrial bus systems. |
| Average Forward Current (IF(AV)) | 2 A per diode - sustainable continuous current under square-wave pulse (δ = 0.5, f = 20 kHz) with Tsp ≤ 135 °C. |
| Forward Voltage (VF) | 410–440 mV at IF = 2 A, Tj = 25 °C - enables <1.0 W conduction loss per diode, reducing thermal burden in high-efficiency SMPS. |
| Reverse Current (IR) | 485–2000 µA at VR = 30 V, Tj = 25 °C - low leakage preserves battery runtime in reverse-polarity protection circuits. |
| Thermal Resistance (Rth(j-sp)) | 12 K/W - measured from junction to cathode solder point; enables direct thermal coupling to PCB copper for passive cooling. |
| Diode Capacitance (Cd) | 60 pF at VR = 10 V, f = 1 MHz - minimizes switching noise and EMI in high-frequency DC-DC converters. |
| Reverse Recovery Time (trr) | 50 ns - fast recovery avoids cross-conduction losses in synchronous rectifier topologies. |
Pinout & Package
Package: DFN2020-3 (SOT1061), 2.0 mm × 2.0 mm × 0.65 mm body, leadless, thermal-enhanced plastic with exposed cathode pad (CC) on underside.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input terminal for first rectification path; connects to input rail or switch node in buck converter. |

Use Scenario: Protecting 12 V/24 V automotive ECUs from battery misconnection during service or jump-start events. IC Role / Device Role / Timing Role: Dual-anode configuration allows independent protection of two power domains (e.g., MCU core and CAN transceiver rails) sharing one ground return. Use Value: 30 V VR rating withstands load-dump transients up to ISO 7637-2 Pulse 5a; low VF ensures <200 mW power loss at 2 A, minimizing thermal derating. |
Use Scenario: Secondary-side rectification in 500 kHz synchronous buck converters powering FPGA or DSP cores. IC Role / Device Role / Timing Role: Functions as freewheeling diode in non-synchronous mode or as backup clamp during MOSFET dead-time in hybrid control schemes. Use Value: 50 ns trr and 60 pF Cd limit ringing and EMI generation; 410 mV VF reduces conduction loss by >30% vs. standard silicon diodes at 2 A. |
| USB-C Power Delivery Input Protection | Portable Device Battery Charger Path Control |
|

IC Role / Device Role / Timing Role: Placed between USB-C receptacle and buck controller to prevent backfeed into upstream source during fault conditions. Use Value: 2 A IF(AV) supports 30 W PD3.0 operation; AEC-Q101 qualification ensures robustness across temperature cycling in consumer automotive accessories. |
Use Scenario: OR-ing diode between wall adapter and battery in smartphones and wearables to enable seamless charging handoff. IC Role / Device Role / Timing Role: Dual-anode layout permits separate connection to AC adapter and wireless receiver coils, with shared cathode to battery node. Use Value: 440 mV max VF at 2 A limits voltage drop to <900 mV, preserving charging efficiency; 2000 µA max IR prevents significant standby drain. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSR20F30NXT5G | Same 30 V/2 A rating but TO-277 package (larger footprint, higher Rth(j-a) ≈ 40 K/W); VF = 450 mV typ at 2 A. | Less suitable for ultra-thin designs due to 1.1 mm height; better suited for through-hole or high-reliability industrial boards. | Select when board-level reworkability or legacy footprint compatibility outweighs thermal density requirements. |
| Vishay VSS80LJ30-M3/86A | DFN2020-3 package, 30 V/2 A, but single-diode configuration; VF = 420 mV typ at 2 A; no AEC-Q101 qualification. | Requires two devices for dual-path use, increasing BOM count and layout area; not approved for automotive end-equipment. | Choose only for cost-sensitive non-automotive applications where dual-anode integration is unnecessary. |
Compared with NSR20F30NXT5G and VSS80LJ30-M3/86A, PMEG3020CPA-QX uniquely combines AEC-Q101 compliance, dual-anode integration in 2×2 mm, and lowest VF among qualified equivalents - delivering superior power density and automotive readiness in a single component.

FAQ
Is PMEG3020CPA-QX pin-compatible with standard SOT-23 or SOD-123 packages?
No. PMEG3020CPA-QX uses the DFN2020-3 (SOT1061) leadless package with three terminals in a 2.0 mm × 2.0 mm footprint and an exposed cathode pad on the bottom. It is not mechanically or electrically compatible with SOT-23 (3-pin, gull-wing leads) or SOD-123 (2-pin, molded plastic) packages. PCB layout must follow the exact solder land pattern specified in Figure 16 of the Nexperia datasheet.
What is the maximum allowable soldering temperature profile for PMEG3020CPA-QX?
PMEG3020CPA-QX is qualified for lead-free reflow only, with peak temperature not exceeding 260 °C for ≤ 30 seconds. Preheat ramp rate must stay within 1–3 °C/s, and time above 217 °C must be 60–150 seconds. Wave soldering is explicitly prohibited per Nexperia's datasheet Section 13, as it risks delamination and thermal damage to the die attach and molding compound.
Does the "-QX" suffix indicate automotive qualification beyond AEC-Q101?
Yes. The "-QX" suffix denotes Nexperia's automotive-grade variant, which meets AEC-Q101 stress test requirements and is manufactured in IATF 16949-certified facilities. It includes additional process controls, lot traceability, and extended temperature screening (−55 °C to +150 °C operating range), distinguishing it from commercial-grade PMEG3020CPA parts without the suffix.
Can PMEG3020CPA-QX be used in parallel configurations to increase current handling?
No. Parallel operation of Schottky diodes is strongly discouraged without active current balancing, due to negative temperature coefficient of VF causing thermal runaway. The datasheet specifies absolute maximum ratings per diode (2 A IF(AV)), and thermal coupling via shared cathode pad further increases imbalance risk. For >2 A applications, select a single higher-current device such as PMEG3030CPA-QX (3 A rating).
