Product details
Overview
PMEG2020AEA-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 2 A forward current, featuring a typical forward voltage of 450 mV at 2 A and housed in an AEC-Q101-qualified SOD323 (SC-76) package. It serves as a low-loss unidirectional power switch in automotive DC/DC converters and reverse polarity protection circuits.
For engineers reviewing the PMEG2020AEA-QX datasheet, PMEG2020AEA-QX pinout, PMEG2020AEA-QX application, or PMEG2020AEA-QX equivalent, key selection criteria include its 450 mV VF at 2 A, 210 K/W Rth(j-sp), AEC-Q101 qualification, and SOD323 thermal pad layout compatibility with FR4 PCBs using standard reflow footprints.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown and improve reliability under transient stress-critical for automotive 12 V rail applications. Its low VF minimizes conduction loss in high-frequency switching topologies where duty cycles exceed 50 %.
Thermal design relies on junction-to-solder-point resistance (90 K/W) measured at the cathode tab, requiring dedicated 1 cm² copper pour per the datasheet. Reverse leakage remains below 200 µA at 20 V and 25 °C, enabling stable operation in low-power standby paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability in automotive 12 V systems with load-dump transients. |
| Forward Current (IF) | 2 A continuous - Supports sustained output in compact buck converters up to 25 W. |
| Forward Voltage (VF) | 450 mV typ. @ 2 A - Reduces conduction loss to ≤0.9 W, enabling >95 % efficiency at light loads. |
| Reverse Leakage (IR) | 200 µA max @ 20 V - Limits standby power loss in always-on vehicle modules. |
| Diode Capacitance (Cd) | 70 pF max @ 5 V - Enables clean switching in 1–3 MHz DC/DC controllers without excessive ringing. |
| Junction Temp (Tj) | 150 °C max - Allows operation in engine bay environments with localized heating. |
| Rth(j-sp) | 90 K/W - Requires cathode-side thermal pad for reliable 2 A operation on FR4 PCBs. |
Pinout & Package
Encapsulated in a SOD323 (SC-76) surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch and tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Primary heat path; must connect to ≥1 cm² copper pour for thermal management. |
| 2 | Anode (A) | Input side of rectification path; routed with minimal trace inductance for EMI control. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Prevents premature edge breakdown during voltage transients in automotive start-stop cycles. |
| AEC-Q101 qualification | Validated for temperature cycling, HTRB, and ESD per automotive discrete stress test requirements. |
| SOD323 footprint | Enables <1.8 mm² board area usage-ideal for space-constrained ADAS sensor modules. |
| Low Rth(j-sp) | 90 K/W enables 2 A operation without external heatsink when mounted per recommended footprint. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Input Stage |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | 30 V VR, 0.5 A IF, higher VF (550 mV @ 0.5 A), DO-214AC package | Larger footprint, lower current rating, unsuitable for 2 A continuous use | Select only for cost-sensitive non-automotive 12 V inputs with <0.5 A load. |
| SS22H | 20 V VR, 2 A IF, VF = 500 mV @ 2 A, SOD-123 package, no AEC-Q101 | Same electrical rating but lacks automotive qualification and guard ring | Acceptable for industrial DC/DC where AEC-Q101 is not mandated and thermal margin exists. |
Compared with RB050M-30 and SS22H, PMEG2020AEA-QX uniquely combines AEC-Q101 qualification, 2 A continuous rating in SOD323, and 450 mV VF-enabling smaller, more robust automotive power stages without derating or package trade-offs.

FAQ
What is the maximum allowable soldering temperature profile for PMEG2020AEA-QX?
The device complies with JEDEC J-STD-020D for moisture sensitivity level 1 and supports peak reflow temperatures up to 260 °C for ≤30 seconds. Recommended profile uses ramp rate ≤3 °C/s, preheat 150–200 °C for 60–120 s, and time above liquidus (217 °C) of 60 ± 15 s, per Nexperia's SOD323 reflow footprint documentation.
Can PMEG2020AEA-QX replace a standard PN-junction diode in a 12 V automotive circuit?
Yes-it replaces PN diodes like 1N4007 in low-voltage rectification roles, delivering 450 mV VF versus ~900 mV, reducing conduction loss by >50 %. However, its higher reverse leakage (200 µA vs. <5 µA) requires verification in high-impedance bias networks or precision reference paths.
Is the SOD323 package thermally adequate for 2 A continuous operation?
Yes, when mounted per Nexperia's recommended footprint (cathode pad ≥1 cm² copper), Rth(j-sp) = 90 K/W enables 2 A continuous operation at Tsp ≤ 55 °C ambient. Without the thermal pad, derating to 1.2 A is required due to Rth(j-a) = 210 K/W in free air.
Does PMEG2020AEA-QX support bidirectional current flow?
No-it is a unidirectional Schottky rectifier. Forward conduction occurs from anode to cathode; reverse bias blocks current up to 20 V. Bidirectional operation would require back-to-back configuration or a dedicated bidirectional switch, neither supported by this single-diode construction.
