Product details
Overview
PMEG4010CPA from Nexperia is a dual common-cathode Schottky barrier rectifier in SOT1061 (DFN2020-3) package, rated for 40 V reverse voltage and 1 A average forward current per diode, with typical forward voltage of 440 mV at 1 A and 25 °C. It delivers low conduction loss in compact high-power-density DC/DC converters and automotive-grade reverse polarity protection circuits.
For engineers reviewing the PMEG4010CPA datasheet, PMEG4010CPA pinout, PMEG4010CPA application, or PMEG4010CPA equivalent, this device is selected for low-VF dual-diode rectification where thermal performance on FR4 or ceramic PCBs, AEC-Q101 qualification, and exposed cathode pad for thermal management are critical design requirements.
Technical Context
This dual Schottky rectifier uses planar junction technology with integrated guard ring for robust ESD and surge stress protection. Its common-cathode configuration enables independent anode control while sharing a thermally enhanced cathode pad-critical for parallel-path power routing in space-constrained SMPS outputs.
The device operates with zero minority-carrier storage, delivering 45 ns reverse recovery time and negligible switching loss. Thermal resistance to solder point is 12 K/W when mounted on standard footprint, enabling reliable 1 A continuous operation up to 140 °C solder point temperature under square-wave pulse conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - Maximum blocking capability per diode; defines usable input range in 24 V automotive or 36 V industrial DC bus applications. |
| Average Forward Current (IF(AV)) | 1 A per diode - Sustained DC or pulsed output current capacity under defined thermal mounting conditions (e.g., FR4 with 1 cm² cathode pad). |
| Forward Voltage (VF) | 440 mV typ. at 1 A, 25 °C - Directly reduces conduction loss by ~440 mW per diode versus higher-VF alternatives, improving efficiency in battery-powered systems. |
| Reverse Current (IR) | 12 µA max at 40 V, 25 °C - Low leakage preserves standby power budget in always-on circuits like USB-C PD port protection. |
| Thermal Resistance (Rth(j-sp)) | 12 K/W - Junction-to-solder-point value confirms effective heat extraction via cathode pad; enables stable operation without external heatsink. |
| Reverse Recovery Time (trr) | 45 ns - Confirms true Schottky behavior; eliminates tail current, simplifying EMI filter design in high-frequency (>500 kHz) SMPS. |
Pinout & Package
Encapsulated in SOT1061 (DFN2020-3): 2 mm × 2 mm × 0.65 mm leadless plastic package with exposed cathode thermal pad. Compatible with reflow-only assembly per JEDEC J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (A1) | Anode of Diode 1 | Input node for first rectification path; connects to source-side rail in dual-output or redundancy configurations. |
| 2 (A2) | Anode of Diode 2 | Independent input node for second rectification path; supports OR-ing, input selection, or dual-rail rectification. |
| 3 (CC) | Common Cathode | Shared output terminal and primary thermal interface; must be soldered to ≥1 cm² copper area for rated power dissipation. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive underhood environments (−40 °C to +150 °C junction), including temperature cycling, HTRB, and ESD testing. |
| Exposed cathode pad | Provides simultaneous low-inductance electrical return and <12 K/W thermal path to PCB, eliminating need for discrete thermal vias in many layouts. |
| Guard ring integration | Prevents edge breakdown under transient overvoltage, increasing reliability in load-dump or inductive-switching scenarios. |
| Low capacitance (50 pF at 10 V) | Minimizes high-frequency coupling noise in fast-switching nodes; maintains signal integrity in synchronous rectifier gate-drive paths. |
Applications
| Battery Charger Output Stage | Automotive Reverse Polarity Protection |
|---|---|
Use Scenario: Dual-input USB-C PD charger with independent 5 V/9 V rails feeding shared battery charging IC. IC Role / Device Role / Timing Role: Dual-anode Schottky rectifier isolates input sources while common cathode delivers consolidated low-loss output to charging controller. Use Value: 440 mV VF minimizes voltage drop across each path, preserving headroom for precise CC/CV regulation and reducing thermal load on compact PCB. | Use Scenario: 12 V vehicle infotainment module requiring protection against accidental reverse battery connection. IC Role / Device Role / Timing Role: Common-cathode diode pair placed in series with main power input, conducting only during correct polarity. Use Value: AEC-Q101 rating ensures survival through automotive load-dump transients; 40 V rating covers 24 V system peaks and ISO 7637-2 pulses. |
| High-Efficiency DC/DC Converter Output | Redundant Power Supply OR-ing |
Use Scenario: 1 MHz buck converter supplying 3.3 V/2 A to FPGA core logic in industrial PLC. IC Role / Device Role / Timing Role: Secondary-side synchronous rectifier replacement; conducts during low-side switch ON phase. Use Value: 45 ns trr prevents shoot-through risk during dead-time transitions, enabling stable operation without complex gate timing compensation. | Use Scenario: Dual 5 V power supplies feeding single backplane in telecom shelf, requiring seamless failover. IC Role / Device Role / Timing Role: Each supply feeds one anode; common cathode delivers unified output, blocking reverse current during fault. Use Value: Matched VF between diodes ensures balanced current sharing; low leakage (<55 µA) prevents cross-conduction during hot-swap events. |
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 | 45 V rating, 0.5 A per diode, SOD-323 package, no exposed thermal pad | Limited to lower-current, non-automotive applications due to smaller package and absence of AEC-Q101 qualification | Select when board space is constrained but thermal demand is ≤0.5 A and automotive compliance is not required. |
| SS34-HF | 40 V, 3 A per diode, DO-214AC package, higher VF (550 mV), no AEC-Q101 | Higher current handling but larger footprint and inferior thermal resistance; suited for cost-sensitive consumer adapters | Choose for legacy through-hole or high-current non-automotive designs where 0.5 A margin and thermal pad are unnecessary. |
Compared with RB055LAM-30TR and SS34-HF, PMEG4010CPA uniquely combines AEC-Q101 qualification, 1 A per diode rating, ultra-low 440 mV VF, and thermally optimized SOT1061 packaging-making it the only option meeting all three criteria for space-limited automotive or industrial DC/DC modules.

FAQ
Is PMEG4010CPA 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 exposed cathode pad and thin DFN2020-3 construction. Reflow profile must comply with JEDEC J-STD-020, peak temperature ≤260 °C.
What is the maximum ambient temperature for 1 A continuous operation?
On FR4 PCB with 1 cm² cathode pad, PMEG4010CPA supports 1 A IF(AV) up to 85 °C ambient (Fig. 10). With ceramic Al₂O₃ substrate, ambient limit rises to 110 °C (Fig. 11). Exceeding these requires derating per thermal resistance curves or active cooling.
Does the common cathode require a dedicated ground plane?
No-it requires a dedicated thermal copper area (≥1 cm²) connected to system ground *only if* the output reference is ground. The cathode pad serves primarily as thermal interface; its electrical connection depends on circuit topology (e.g., floating output in isolated DC/DC).
How does the guard ring improve reliability in automotive use?
The integrated guard ring suppresses electric field crowding at the silicon edge, preventing premature avalanche breakdown during load-dump transients (ISO 7637-2 Pulse 5a). This extends device lifetime under repeated 120 V surge events without external TVS clamping.
