Product details
Overview
PMEG2010BEA-QX from Nexperia is a 1 A, 20 V planar Schottky barrier rectifier with integrated guard ring for stress protection, housed in an ultra-compact SOD323 (SC-76) package. It delivers a typical forward voltage of 420 mV at 1 A and 25 °C, enabling high-efficiency low-voltage DC-to-DC conversion and reverse-polarity protection in space-constrained automotive modules.
For engineers reviewing the PMEG2010BEA-QX datasheet, PMEG2010BEA-QX pinout, PMEG2010BEA-QX application, or PMEG2010BEA-QX equivalent, key selection criteria include its AEC-Q101 qualification, 450 K/W junction-to-ambient thermal resistance on FR4, 66–80 pF diode capacitance at 1 V/1 MHz, and cathode/anode polarity mapping for PCB layout verification.
Technical Context
This Schottky rectifier uses a planar die structure with an integrated guard ring to suppress edge breakdown under transient stress, supporting reliable operation in automotive power rails subject to load dump and cold-crank conditions. Its low VF minimizes conduction loss in 3.3 V and 5 V supply paths where forward current remains ≤1 A.
The device operates within a −65 °C to +150 °C ambient range and exhibits thermal runaway sensitivity due to reverse leakage contribution to total power dissipation-requiring thermal design consideration when VR ≥10 V and Tamb >85 °C per manufacturer nomograms.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Current (IF) | 1 A continuous - supports sustained output rectification in compact DC-DC converters without derating on standard FR4 PCB. |
| Reverse Voltage (VR) | 20 V - suitable for 12 V automotive systems with margin for ISO 7637-2 pulse 5a (load dump up to 27 V). |
| Forward Voltage (VF) | 420–500 mV @ 1 A, 25 °C - reduces power loss to ≤500 mW, critical for thermally isolated modules. |
| Reverse Current (IR) | 40–200 µA @ 20 V, 25 °C - limits standby leakage in always-on vehicle networks. |
| Diode Capacitance (Cd) | 66–80 pF @ 1 V, 1 MHz - enables fast switching in buck converter freewheeling paths with minimal ringing. |
| Junction-to-Ambient Rth(j-a) | 450 K/W - defines maximum temperature rise under free-air conditions; requires thermal pad or copper pour for >500 mA operation. |
Pinout & Package
Encapsulated in the SOD323 (SC-76) surface-mount plastic package measuring 1.7 mm × 1.25 mm × 0.95 mm with 1.3 mm lead pitch, this two-terminal device uses standard FR4-compatible reflow footprints (Fig. 5) and wave-solder land patterns (Fig. 6).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse-biased blocking configuration; solder pad serves as primary thermal path (Rth(j-sp) = 90 K/W). |
| 2 | Anode (A) | Connected to lower-potential node during conduction; carries full forward current with minimal parasitic inductance due to short internal bond wire. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q101 qualified | Validated for automotive-grade reliability including HTOL, temperature cycling, and ESD HBM ≥2 kV - eliminates qualification overhead for Tier 1 BOMs. |
| Integrated guard ring | Suppresses edge-related avalanche breakdown under repetitive surge stress, extending lifetime in clamping circuits exposed to ISO 16750-2 transients. |
| Ultra-low VF profile | Sub-500 mV drop at 1 A enables >95% efficiency in 3.3 V buck outputs with minimal heatsinking. |
| SOD323 footprint | 1.7 mm × 1.25 mm body allows placement in dense ADAS sensor modules where board area is constrained by optical or RF layout. |
Applications
| Automotive Body Control Module (BCM) | USB-C Power Delivery Clamp |
|---|---|
Use Scenario: Reverse-polarity protection on 12 V input rail of door module MCU power supply. IC Role / Device Role / Timing Role: Unidirectional blocking diode preventing damage during battery jump-start misconnection.

IC Role / Device Role / Timing Role: Fast-turn-on clamp limiting overshoot to <20 V during ESD or inductive kickback. Use Value: 66–80 pF capacitance ensures sub-nanosecond response without signal integrity degradation on 10 Gbps data lanes. |
| Low-Power IoT Sensor Node | Industrial 24 V Fieldbus Interface |

IC Role / Device Role / Timing Role: Prevents backfeed during main supply brownout while minimizing standby current drain. Use Value: 40 µA max IR at 20 V keeps annual self-discharge below 1% of typical CR2032 capacity. |

Use Value: 10 A non-repetitive peak forward current (IFSM) handles 24 V/1 H solenoid energy without secondary snubber. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30TR | Higher VF (520 mV typ @ 1 A), same 20 V VR, larger SOD-123 package (2.7 mm × 1.6 mm). | Less suitable for ultra-dense layouts; better thermal performance (Rth(j-a) = 300 K/W) in forced-air environments. | Select when board-level airflow exists and footprint tolerance allows +58% area increase. |
| SS12HE3/5BT | Same SOD-323 size but 2 A rating and 30 V VR; VF = 500 mV typ @ 1 A - 80 mV higher than PMEG2010BEA-QX. | Over-specified VR margin for 12 V systems; higher leakage (100 µA typ @ 20 V) increases standby loss. | Choose only if future 24 V system migration or higher surge immunity is required. |
Compared with RB050M-30TR and SS12HE3/5BT, PMEG2010BEA-QX offers the lowest VF in SOD323, making it optimal for thermally isolated, space-limited 12 V automotive nodes where every millivolt of conduction loss impacts thermal budget and battery runtime.

FAQ
Is PMEG2010BEA-QX suitable for synchronous rectification?
No. This is a passive Schottky rectifier with fixed anode/cathode polarity and no gate control. It functions only as a unidirectional conduction path and cannot replace actively switched MOSFETs in synchronous buck topologies requiring gate timing signals.
What is the maximum allowable PCB temperature rise during 1 A DC operation?
At 1 A and 25 °C ambient, junction temperature reaches ~120 °C using Rth(j-a) = 450 K/W. To maintain Tj ≤ 150 °C, PCB temperature rise must be limited to ≤30 °C - achievable with ≥1 cm² cathode-side copper pour per manufacturer thermal guidelines.
Does the "-QX" suffix indicate a different specification than "-Q"?
No. The "-QX" suffix denotes Aetrix Electronics' internal packaging and traceability variant of the standard Nexperia PMEG2010BEA-Q part. Electrical, thermal, and mechanical specifications remain identical to the base -Q grade per datasheet v.3 (20230901).
Can PMEG2010BEA-QX be used in AC rectification?
No. With only 20 V reverse voltage rating and no specified AC waveform derating, it is unsuitable for mains-derived AC/DC applications. It is designed exclusively for low-voltage DC blocking, clamping, and freewheeling in automotive and portable electronics.
