Product details
Overview
PMEG3010BEA-QX from Nexperia is a 1 A, 30 V low-forward-voltage Schottky barrier rectifier in SOD323 (SC-76) package, featuring an integrated guard ring for stress protection and AEC-Q101 qualification for automotive use. It delivers VF = 450–560 mV at IF = 1 A and IR = 40–150 µA at VR = 30 V, enabling high-efficiency DC-to-DC conversion and low-voltage clamping in space-constrained automotive ECUs.
For engineers reviewing the PMEG3010BEA-QX datasheet, PMEG3010BEA-QX pinout, PMEG3010BEA-QX application, or PMEG3010BEA-QX equivalent, key selection criteria include its ultra-low VF, AEC-Q101 qualification, thermal resistance Rth(j-sp) = 90 K/W, SOD323 footprint compatibility, and suitability for automotive-grade reverse polarity protection and blocking diode functions.
Technical Context
This MEGA Schottky rectifier uses planar silicon technology with an integrated guard ring to suppress edge breakdown and improve robustness under transient stress. Its low junction-to-solder-point thermal resistance (90 K/W) supports reliable operation up to 150 °C junction temperature in thermally constrained PCB layouts.
The device exhibits low capacitance (55–70 pF at VR = 1 V, f = 1 MHz) and fast switching behavior due to absence of minority-carrier storage, making it suitable for high-frequency rectification and voltage clamping where low dynamic losses are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 450–560 mV at IF = 1 A - enables <150 mW conduction loss in 3.3 V/5 V rail protection circuits |
| Reverse Voltage (VR) | 30 V maximum - supports 24 V automotive systems with 2× safety margin against load dump transients |
| Reverse Current (IR) | 40–150 µA at VR = 30 V - ensures minimal leakage in battery-backed backup paths |
| Diode Capacitance (Cd) | 55–70 pF at VR = 1 V, 1 MHz - limits high-frequency noise coupling in SMPS feedback networks |
| Junction-to-Solder-Point Rth | 90 K/W - allows direct thermal path to copper pour, reducing thermal derating in compact layouts |
| Peak Forward Surge Current | 10 A (8 ms square wave) - withstands inrush during hot-plug events in infotainment power rails |
| AEC-Q101 Qualified | Yes - validated for automotive applications including engine control, body electronics, and ADAS sensors |
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 cathode-side marking bar. The package is optimized for reflow and wave soldering per IPC-7351B standards.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse-biased protection; marked side of package; primary heat path to PCB copper |
| 2 | Anode (A) | Connected to lower-potential node (e.g., battery negative or ground); electrically isolated from cathode tab in layout |
Key Features
| Feature | Design Value |
|---|---|
| Guard Ring Integration | Suppresses edge breakdown under high dv/dt, improving reliability in noisy automotive environments |
| Low Thermal Resistance | Rth(j-sp) = 90 K/W enables >80% of rated current at Tsp ≤ 55 °C on standard FR4 |
| AEC-Q101 Qualification | Validated across HTOL, TC, HAST, and ESD tests - meets automotive component lifetime requirements |
| Ultra-Small Footprint | SOD323 package saves >60% board area vs. SOD123 while maintaining 1 A rating |
Applications
| Automotive Reverse Polarity Protection | USB Power Path Management |
|---|---|
Use Scenario: Protecting 12 V vehicle infotainment head units from battery misconnection during service. IC Role / Device Role / Timing Role: Series-blocking Schottky diode placed between battery input and system regulator. Use Value: 450 mV VF minimizes voltage drop and power loss (<450 mW at 1 A), preserving system efficiency without heatsinking. |
Use Scenario: OR-ing two USB-C power sources (host + adapter) in portable diagnostic tools. IC Role / Device Role / Timing Role: Low-loss forward path selector preventing backfeed between sources. Use Value: 70 pF capacitance avoids signal integrity degradation on USB 2.0 D+/D− lines near power switches. |
| Low-Voltage DC-DC Output Rectification | ESD-Sensitive Sensor Clamping |
Use Scenario: Secondary-side rectification in 3.3 V synchronous buck converter for ADAS camera modules. IC Role / Device Role / Timing Role: Freewheeling diode replacing MOSFET body diode in asynchronous mode. Use Value: 560 mV max VF reduces conduction loss by ~30% vs. standard Schottky alternatives, lowering thermal load on 4-layer PCB. |
Use Scenario: I/O line clamping for CAN FD transceivers exposed to ISO 10605 ESD pulses. IC Role / Device Role / Timing Role: Low-capacitance shunt clamp limiting transient voltage to <33 V. Use Value: 150 µA max IR at 30 V ensures negligible standby current in always-on sensor nodes. |
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 | Higher VF (550–750 mV @ 1 A), same VR (30 V), SOD-123 package (2.8 mm × 1.7 mm) | Larger footprint; less suitable for ultra-dense automotive modules | Prefer when thermal mass requirement exceeds SOD323 capability and board space permits |
| SS12 | Lower VR (20 V), higher IF (1.2 A), DO-214AC package (4.5 mm × 2.7 mm) | Not AEC-Q101 qualified; unsuitable for automotive under-hood use | Select only for cost-sensitive industrial non-automotive applications with <20 V rails |
Compared with RB050M-30 and SS12, PMEG3010BEA-QX offers the smallest footprint among AEC-Q101-qualified 30 V Schottkys, lowest VF in SOD323, and best thermal performance per unit area-critical for ECU miniaturization and thermal management in confined enclosures.

FAQ
Is PMEG3010BEA-QX suitable for 48 V mild-hybrid automotive systems?
No. Its 30 V reverse voltage rating provides insufficient margin against 48 V system transients (e.g., ISO 16750-2 load dump peaks up to 60 V). For 48 V applications, consider Nexperia's PMEG6020CPA-Q (60 V, SOD323) or PMEG4020CPA-Q (40 V, SOD323), both AEC-Q101 qualified.
What is the maximum continuous forward current at 100 °C ambient temperature?
At Tamb = 100 °C on standard FR4 (single-sided copper), derating reduces the usable IF to approximately 0.65 A, based on thermal resistance Rth(j-a) = 450 K/W and Tj(max) = 150 °C. Layout with extended cathode copper improves this to ≥0.85 A.
Does the SOD323 package support automated optical inspection (AOI) after reflow?
Yes. The SOD323 outline (IEC 60747-16 compliant) and cathode marking bar enable reliable AOI detection. Recommended solder paste stencil aperture is 0.5 mm × 0.6 mm per pad, with 100% coverage and no bridging observed in validated reflow profiles.
Can PMEG3010BEA-QX replace BAT54S in existing designs?
Only with layout review. BAT54S is a dual common-cathode Schottky in SOT-23; PMEG3010BEA-QX is single-diode SOD323. Electrical specs overlap (30 V, ~1 A), but pin count, footprint, and thermal path differ significantly-direct replacement requires PCB redesign and thermal validation.
