Product details
Overview
PMEG4010CPASX from Nexperia is a dual common-cathode Schottky barrier rectifier optimized for low-voltage, high-efficiency power conversion. It delivers 1 A average forward current per diode at ≤500 mV forward voltage (IF = 1 A, Tj = 25 °C), with 40 V reverse voltage rating and AEC-Q101 qualification-used in automotive-grade DC-DC converters and mobile battery chargers.
For engineers reviewing the PMEG4010CPASX datasheet, PMEG4010CPASX pinout, PMEG4010CPASX application, or PMEG4010CPASX equivalent, key selection criteria include ultra-low VF for thermal efficiency, DFN2020D-3 package thermal performance, common-cathode dual-diode topology for space-constrained buck/flyback outputs, and AOI-compatible side pads for production traceability.
Technical Context
This dual Schottky rectifier integrates two independent anodes (A1, A2) sharing a single exposed cathode pad (K) in a planar MEGA structure with guard ring stress protection. Its low 440 mV typical VF at 1 A enables high-efficiency synchronous rectification replacement in sub-5 V output rails.
The DFN2020D-3 (SOT1061D) package features solderable side terminals and a thermally enhanced copper cathode pad, achieving 12 K/W junction-to-solder-point thermal resistance-critical for sustained 1 A operation on compact FR4 PCBs without heatsinks.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 1 A | 440–500 mV - Enables ≥92% efficiency in 3.3 V/1 A buck converters with minimal conduction loss |
| VR | 40 V - Supports input ranges up to 36 V automotive systems and 24 V industrial rails |
| IF(AV) per diode | 1 A - Rated for continuous operation at full load in compact DC-DC modules |
| IR @ 40 V | 12–55 µA - Low leakage preserves battery runtime in always-on mobile applications |
| trr | 3.5 ns - Eliminates switching loss penalties in >1 MHz SMPS designs |
| Cd @ 10 V | 50 pF - Minimizes capacitive coupling noise in sensitive analog power domains |
| Rth(j-sp) | 12 K/W - Allows direct thermal coupling to PCB ground plane for passive cooling |
Pinout & Package
Package: DFN2020D-3 (SOT1061D), 2.0 × 2.0 × 0.65 mm, leadless, thermally enhanced with visible side pads and exposed cathode tab.
| Pin/Terminal | Circuit Role | Design Meaning |

| Exposed cathode pad | Reduces thermal resistance by 70% vs. standard SOT packages-enables 1 A operation on 1-layer FR4 |
| Guard ring integration | Prevents edge breakdown under mechanical stress or humidity-critical for automotive vibration environments |
| AOI-compatible side pads | Enables automated optical inspection of solder joints without X-ray-reduces manufacturing defect escape |
| Ultra-thin 0.65 mm profile | Permits stacking under shields or in ultra-slim portable enclosures (e.g., smartphone charging modules) |
Applications
| Automotive USB-C Power Delivery | Mobile Phone Battery Charger IC Output Stage |
|---|---|
Use Scenario: Dual-port 18 W USB-C PD adapter with independent 5 V/3 A and 9 V/2 A outputs. IC Role / Device Role / Timing Role: Common-cathode dual Schottky rectifier replacing two discrete diodes to reduce BOM count and footprint.

IC Role / Device Role / Timing Role: Output rectifier for buck stage feeding linear regulator; handles 1 A continuous output current. Use Value: 12 µA max IR at 40 V prevents standby current drain-extending shelf life of sealed medical wearables beyond 12 months. |

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 | 40 V VR, 0.5 A IF(AV), SOD-323 package, VF = 450 mV @ 0.5 A | Lower current rating; unsuitable for >0.6 A continuous loads | Select only for space-constrained <0.5 A applications where thermal mass is sufficient |
| SS34-HF | 40 V VR, 3 A IF(AV), SMA package, VF = 550 mV @ 3 A, no AEC-Q101 | Larger footprint (4.5 × 2.7 mm), higher VF, non-automotive qualified | Use for cost-sensitive industrial supplies where AEC-Q101 and ultra-low VF are not required |
Compared with RB055LAM-30TR and SS34-HF, PMEG4010CPASX uniquely balances 1 A current, 440 mV VF, AEC-Q101 compliance, and 2.0 mm × 2.0 mm footprint-making it the only option for automotive-compliant, high-density 1 A DC-DC rectification.

FAQ
Is PMEG4010CPASX suitable for synchronous rectification replacement in 1 MHz DC-DC converters?
Yes. With a 3.5 ns reverse recovery time and 50 pF capacitance at 10 V, PMEG4010CPASX minimizes switching losses and EMI generation in high-frequency buck converters. Its low 440 mV forward voltage ensures conduction loss remains below 0.44 W at 1 A-critical for maintaining >90% efficiency at 1 MHz.
What is the maximum allowable ambient temperature for continuous 1 A operation on standard FR4 PCB?
On standard FR4 with single-sided 1 oz copper and no thermal pad, PMEG4010CPASX supports 1 A average forward current up to 110 °C ambient temperature (δ = 0.5, f = 20 kHz square wave). This is validated in Figure 9 of the datasheet and enabled by its 250 K/W junction-to-ambient thermal resistance.
Does the common cathode configuration support independent control of each diode's conduction?
No. The cathodes are internally bonded together and externally accessible only as a single terminal (Pin 3). Each anode (Pins 1 and 2) operates independently, but both share the same cathode potential-ideal for dual-output supplies or redundancy, not for bidirectional or actively switched paths.
How does the guard ring improve reliability in automotive applications?
The integrated guard ring prevents premature edge breakdown under mechanical stress, humidity, or voltage transients-key failure modes in automotive environments. It extends device lifetime under temperature cycling (−40 °C to +125 °C ambient) and dampens localized electric field concentration at silicon edges during load dump events.
