Product details
Overview
PMEG4010CPA-QX from Nexperia is a dual Schottky barrier rectifier in common-cathode configuration, designed for low-voltage, high-efficiency power conversion. It delivers 1 A average forward current per diode at ≤440 mV forward voltage (IF = 1 A, Tj = 25 °C), with 40 V reverse voltage rating and AEC-Q101 qualification - enabling use in automotive-grade DC-DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG4010CPA-QX datasheet, PMEG4010CPA-QX pinout, PMEG4010CPA-QX application, or PMEG4010CPA-QX equivalent, key selection criteria include its low VF performance, thermal-enhanced DFN2020-3 (SOT1061) package with exposed cathode pad, dual-anode/common-cathode topology, and verified operation up to 150 °C junction temperature.
Technical Context
This device integrates two planar Schottky diodes sharing a common cathode terminal, with an on-chip guard ring for enhanced ESD and surge stress resilience. Its low-barrier metal-semiconductor junction enables fast switching (trr = 45 ns typical) and negligible reverse recovery charge - critical for high-frequency SMPS topologies operating above 20 kHz.
The SOT1061 package features an exposed copper cathode pad that serves as both thermal sink and electrical return path, reducing Rth(j-sp) to 12 K/W and supporting 1.8 W total power dissipation when mounted on ceramic substrate. Thermal derating curves confirm sustained 1 A IF(AV) capability up to 110 °C ambient on FR4 with 1 cm² cathode pad.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VF @ 1 A | 440–500 mV - Enables <0.5 W conduction loss per diode at full load, improving system efficiency in battery-powered DC-DC stages. |
| VR | 40 V - Supports 24 V automotive rail and 36 V industrial bus applications with 10 % safety margin. |
| IF(AV) per diode | 1 A - Rated for continuous square-wave operation (δ = 0.5, f = 20 kHz) with ambient ≤110 °C on ceramic PCB. |
| IR @ 40 V | 12–55 µA - Low leakage preserves battery standby life in always-on mobile charger circuits. |
| trr | 45 ns - Minimizes switching losses and EMI in synchronous rectifier and flyback converter designs. |
| Rth(j-sp) | 12 K/W - Direct thermal path from junction to solder point enables compact layout without external heatsink. |
| Package | DFN2020-3 (SOT1061) - 2 mm × 2 mm × 0.65 mm footprint with 1.3 mm pin pitch; compatible with standard reflow profiles. |
Pinout & Package

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-40TR | Single-diode SOD-123FL package; 40 V VR, 0.5 A IF(AV); VF = 450 mV @ 0.5 A | Limited to single-rail use; lower current rating requires paralleling for 1 A loads | Select only when space allows two devices and thermal budget permits higher Rth(j-a). |
| SS34-HF | DO-214AC package; 40 V VR, 3 A IF(AV); VF = 500 mV @ 3 A; no AEC-Q101 qualification | Through-hole or larger SMD footprint; lacks automotive qualification and guarded die structure | Prefer for cost-sensitive industrial power supplies where AEC-Q101 is not required. |
Compared with RB055LAM-40TR and SS34-HF, PMEG4010CPA-QX uniquely combines dual-diode integration, AEC-Q101 compliance, 1 A per diode rating, and ultra-low-profile thermal packaging - making it optimal for space-constrained automotive and portable power designs requiring reliability and efficiency.

FAQ
What is the maximum allowable junction temperature for PMEG4010CPA-QX?
The absolute maximum junction temperature is 150 °C, validated per IEC 60134 limiting values. Operation at this limit requires thermal design ensuring Rth(j-a) ≤70 K/W on ceramic PCB or active cooling; derating to 125 °C junction is recommended for >10-year automotive reliability.
Can PMEG4010CPA-QX be used in parallel for higher current handling?
No - the device is not characterized or guaranteed for parallel operation. Its matched dual-diode structure is intended for independent anode routing, not current sharing. For >1 A per path, select a higher-rated single-diode part or verify matching with thermal feedback in prototype testing.
Is the exposed cathode pad electrically isolated from other terminals?
Yes - the exposed cathode pad (Pin 3, CC) is the sole electrical connection to the cathode of both diodes and is not internally connected to any other terminal. It must be soldered to a dedicated PCB copper pour serving as both thermal sink and circuit return path.
Does PMEG4010CPA-QX support wave soldering or hand soldering?
No - the datasheet explicitly states reflow soldering is the only qualified method (J-STD-020 compliant). Wave soldering causes delamination due to thermal mismatch, and hand soldering risks exceeding peak temperature limits; both void the AEC-Q101 qualification.
