Product details
Overview
PMEG3020CPAS-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 ≤440 mV forward voltage (IF = 2 A, Tj = 25 °C), supports 30 V reverse voltage, and features AEC-Q101 qualification for automotive-grade reliability in space-constrained DC-DC converters and battery charging circuits.
For engineers reviewing the PMEG3020CPAS-QX datasheet, PMEG3020CPAS-QX pinout, PMEG3020CPAS-QX application, or PMEG3020CPAS-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 specification (IR = 485–2000 µA at VR = 30 V).
Technical Context
This dual Schottky rectifier uses planar MEGA technology with an integrated guard ring to suppress edge breakdown and improve surge robustness. Its common-cathode configuration enables shared thermal path and simplified PCB layout in synchronous rectification or dual-rail output stages.
The device operates with zero recovery time (trr = 4 ns typical) and low junction capacitance (Cd = 60 pF at VR = 10 V, f = 1 MHz), minimizing switching losses in high-frequency SMPS topologies up to several hundred kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| IF(AV) | 2 A per diode - supports continuous 2 A load current in each channel under standard thermal conditions (δ = 0.5, f = 20 kHz, Tsp ≤ 135 °C). |
| VF | 410–440 mV at IF = 2 A - reduces conduction loss by >30% vs. standard Schottkys, enabling higher efficiency in <5 V output rails. |
| VR | 30 V - suitable for 24 V automotive systems with margin for transients and ripple. |
| IR | 485–2000 µA at VR = 30 V - low leakage preserves battery life in always-on mobile and telematics modules. |
| trr | 4 ns - eliminates reverse recovery loss, critical for high-frequency (>500 kHz) buck converters and flyback snubbers. |
| Rth(j-sp) | 12 K/W - enables direct thermal coupling to PCB copper, supporting >1.5 W dissipation without heatsink in FR4 layouts. |
| Cd | 60 pF at VR = 10 V - minimizes capacitive switching loss and EMI generation during fast turn-off. |
Pinout & Package
Encapsulated in the ultra-thin DFN2020D-3 (SOT1061D) leadless package (2.0 × 2.0 × 0.65 mm), featuring visible and solderable side pads and an exposed cathode thermal pad on the bottom surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode Diode 1 (A1) | Input terminal for first Schottky diode; connects to input rail or switch node in half-bridge configurations. |
| 2 | Anode Diode 2 (A2) | Independent input terminal for second diode; enables dual-output or redundancy paths without shared anode routing. |
| 3 | Common Cathode (K) | Shared output/return node with large copper area for low-inductance, low-resistance thermal and electrical path to PCB ground plane. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive applications including engine control units and ADAS power supplies with full temperature cycling, HTRB, and ESD testing. |
| Exposed cathode pad | Provides 12 K/W junction-to-solder-point thermal resistance-enables >1.5× higher power handling vs. standard SOT23 packages at same footprint. |
| Guard ring integration | Suppresses edge leakage and improves voltage standoff consistency across manufacturing lots and temperature extremes. |
| AOI-compatible side pads | Enables automated optical inspection of solder joints-reducing field failure risk in high-volume automotive PCB assembly. |
| Ultra-thin 0.65 mm profile | Allows placement under connectors or beneath shields in slim-profile infotainment and ADAS camera modules. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Adapter |
|---|---|
Use Scenario: Dual-rail 5 V/3.3 V local regulation from 12 V battery with reverse polarity protection and load dump tolerance. IC Role / Device Role / Timing Role: Common-cathode dual rectifier provides independent freewheeling paths for two synchronous buck controllers while sharing thermal mass. Use Value: 440 mV VF reduces conduction loss by 0.88 W per diode vs. legacy 600 mV parts-cutting thermal rise by >15 °C in sealed BCM enclosures. | Use Scenario: Secondary-side synchronous rectification in 20–60 W USB-PD flyback adapters with dual output capability (e.g., 5 V + 9 V). IC Role / Device Role / Timing Role: Dual Schottky replaces two discrete devices, simplifying layout and reducing parasitic inductance in high-frequency (≥150 kHz) transformer secondary winding. Use Value: 4 ns trr eliminates reverse recovery spikes, lowering EMI filter component count and passing CISPR-32 Class B with 3 dB margin. |
| Mobile Phone Battery Charger IC | LED Backlight Driver for Automotive Display |
Use Scenario: Input rectification and reverse polarity protection in single-cell Li-ion linear charger modules with tight board area constraints. IC Role / Device Role / Timing Role: Dual anodes accept either USB or proprietary adapter input; common cathode feeds charger IC input with minimal voltage drop. Use Value: 2.0 × 2.0 mm DFN2020D-3 saves 65% board area vs. SO-8 dual diodes-enabling integration into sub-10 mm² charger subsystems. | Use Scenario: Freewheeling path for boost converter driving 4–6 series white LEDs in instrument cluster backlighting (12–48 V input). IC Role / Device Role / Timing Role: Low-VF dual rectifier handles peak currents during PWM dimming transitions while maintaining stable LED current regulation. Use Value: 485 µA max IR at 30 V prevents standby current drain exceeding 1 µA per string-extending display-off battery life beyond 30 days. |
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-30TR | Higher VF (490 mV typ. @ 2 A), larger SOD-123FL package (3.5 × 1.6 mm), no AEC-Q101 rating | Suitable for industrial DC-DC but not automotive due to qualification gap and thermal derating limitations | Select only for cost-sensitive non-automotive designs where 50 mV VF penalty and 3× footprint increase are acceptable |
| SS24HM3/H | Single-diode SOD-123 package, 40 V VR, VF = 500 mV @ 2 A, no common-cathode configuration | Requires two devices and extra routing for dual-channel use-increases layout complexity and parasitic inductance | Choose only when dual-anode/common-cathode topology is unnecessary and board space allows discrete placement |
Compared with RB055LAM-30TR and SS24HM3/H, PMEG3020CPAS-QX offers superior thermal performance (12 K/W vs. ≥45 K/W), 100% smaller footprint than dual SS24s, and automotive qualification-making it the only option meeting AEC-Q101, space, and efficiency requirements simultaneously.

FAQ
What is the maximum allowable junction temperature for PMEG3020CPAS-QX?
The absolute maximum junction temperature is 150 °C, as defined in the limiting values table. Operation above this threshold risks permanent degradation of the Schottky barrier and accelerated leakage current growth. Derating curves in Figures 10–13 show that sustained 2 A average current requires ambient temperatures below 75 °C on FR4 PCBs without forced cooling.
Does PMEG3020CPAS-QX support reflow soldering per JEDEC J-STD-020?
Yes-the DFN2020D-3 package is qualified for standard lead-free reflow profiles (peak 260 °C, 30 s max). Figure 17 provides the recommended solder paste stencil and land pattern, and the device's side-wettable flanks enable AOI verification of solder joint integrity post-reflow.
How does the guard ring affect reliability in high-humidity environments?
The integrated guard ring mitigates surface leakage paths along the silicon edge, reducing sensitivity to moisture-induced surface conduction. This design feature contributes to the device's AEC-Q101 qualification, which includes 1000-hour unbiased HAST (Highly Accelerated Stress Test) at 130 °C/85% RH with no parametric shift beyond limits.
Can PMEG3020CPAS-QX be used in reverse polarity protection with bidirectional current flow?
No-it is a unidirectional Schottky rectifier configured as dual anodes to common cathode. For reverse polarity protection, it must be placed with anodes toward the input and cathode toward the load. Bidirectional current requires external circuitry (e.g., back-to-back MOSFETs); this device conducts only from anode to cathode in both channels.
