Product details
Overview
PMEG2010EA-QF from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1 A forward current, featuring ultra-low forward voltage (480–550 mV @ 1 A) and qualified to AEC-Q101 for automotive use in clamping and protection circuits.
For engineers reviewing the PMEG2010EA-QF datasheet, PMEG2010EA-QF pinout, PMEG2010EA-QF application, or PMEG2010EA-QF equivalent, key selection criteria include low VF performance under 1 A load, thermal resistance (180–220 K/W), SOD323 package footprint compatibility, and AEC-Q101 qualification status for harsh-environment deployment.
Technical Context
This Schottky diode employs a planar structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability in transient-prone automotive subsystems. Its low barrier height enables fast switching (ultra high-speed) and minimal conduction loss.
The device operates with junction temperatures up to 150 °C and supports non-repetitive peak forward currents of 5 A (8.3 ms half-sine). Thermal performance depends on PCB copper area: Rth(j-a) is 220 K/W on 10×10 mm FR4 and 180 K/W on 40×40 mm FR4 - critical for thermal design in space-constrained modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - defines maximum allowable DC or peak reverse bias before breakdown; sets clamping ceiling in protection circuits. |
| Forward Current (IF) | 1 A continuous - specifies steady-state conduction capability; determines trace sizing and thermal pad requirements. |
| Forward Voltage (VF) | 480–550 mV @ 1 A - directly reduces power loss (P = I × VF) and self-heating in high-duty-cycle paths. |
| Reverse Current (IR) | 10–50 µA @ 15 V - low leakage preserves signal integrity in high-impedance nodes and minimizes standby power drain. |
| Diode Capacitance (Cd) | 19–25 pF @ 5 V - enables effective high-frequency clamping without excessive signal distortion or ringing. |
| Junction Temperature (Tj) | 150 °C max - allows operation in under-hood automotive environments without derating at ambient ≤125 °C. |
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, this diode uses a two-terminal configuration optimized for automated placement and reflow soldering on compact PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node during forward conduction; polarity-sensitive terminal for correct orientation in clamping or rectification paths. |
| 2 (A) | Anode | Connected to lower-potential node during forward conduction; forms current path with cathode when forward-biased. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves ESD and surge immunity by distributing electric field stress, extending lifetime in automotive transients. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JEDEC standards. |
| Ultra-low VF | Reduces conduction loss by >30% vs. standard Schottkys at 1 A, lowering thermal load in battery-fed systems. |
| SOD323 footprint | Enables high-density layout in ADAS sensors, body control modules, and infotainment power rails with minimal board area. |
Applications
| Automotive LED Headlamp Clamping | USB Port Overvoltage Protection |
|---|---|
Use Scenario: Suppresses inductive kickback from LED driver MOSFETs during PWM dimming in headlamp modules. IC Role / Device Role / Timing Role: Fast-switching clamp diode placed across driver output to limit voltage spikes to ≤20 V. Use Value: Prevents gate oxide damage to 30 V-rated drivers using only 20 V VR rating, enabled by sub-550 mV VF and <100 ns recovery. |
Use Scenario: Blocks reverse current and clamps ESD transients on VBUS line of USB 2.0 ports in infotainment head units. IC Role / Device Role / Timing Role: Bidirectional protection element between USB connector and PMIC input, leveraging low Cd and fast response. Use Value: Limits clamping voltage to <18 V during ±15 kV contact discharge (IEC 61000-4-2), with leakage <50 µA preserving sleep-mode current budget. |
| Engine Control Unit (ECU) Power Rail Protection | Start-Stop System Battery Backup Diode |
Use Scenario: Isolates main 12 V rail from auxiliary 5 V microcontroller supply during cold-crank events where battery dips to 6 V. IC Role / Device Role / Timing Role: Reverse-polarity and backfeed prevention diode in dual-rail power domain interface. Use Value: Maintains system uptime via <550 mV forward drop at 1 A, minimizing voltage sag while supporting 150 °C junction operation near engine bay heat sources. |
Use Scenario: Enables seamless handover between main battery and supercapacitor backup during engine restart in 48 V mild-hybrid start-stop systems. IC Role / Device Role / Timing Role: Low-loss OR-ing diode in energy storage path, conducting only when backup voltage exceeds main rail. Use Value: Delivers >95% power transfer efficiency (vs. ~90% with standard diodes) due to 480 mV typical VF, reducing thermal stress on 40×40 mm PCB copper. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (550–650 mV @ 1 A), same 20 V VR, larger SOD-123 package (2.5 × 1.3 mm). | Less suitable for ultra-thin modules; acceptable where board space permits and thermal margin exists. | Select when legacy footprint compatibility with SOD-123 is required and AEC-Q101 is not mandatory. |
| SS12-A | Lower IF rating (200 mA), higher VR (25 V), same SOD323 package, no AEC-Q101 qualification. | Not recommended for automotive power rails; limited to low-current signal-level clamping. | Choose only for cost-sensitive consumer electronics where 1 A capacity and automotive qualification are unnecessary. |
Compared with RB050M-30 and SS12-A, PMEG2010EA-QF uniquely combines AEC-Q101 qualification, 1 A current handling, ultra-low VF, and SOD323 miniaturization - making it the only option meeting all three requirements simultaneously for next-gen automotive power management.

FAQ
Is PMEG2010EA-QF suitable for reflow soldering?
Yes. The SOD323 package is fully compatible with standard lead-free reflow profiles, including IPC/JEDEC J-STD-020. Recommended peak temperature is 260 °C for ≤30 seconds, with preheat ramp rate ≤3 °C/s. Footprint dimensions and solder paste stencil recommendations are provided in Figures 5 and 6 of the official datasheet.
What is the meaning of the 'Q' suffix in PMEG2010EA-QF?
The 'Q' suffix denotes AEC-Q101 qualification per Automotive Electronics Council standards, confirming full stress-test validation for temperature cycling, high-temperature reverse bias, and ESD robustness. The 'F' in PMEG2010EA-QF is a Nexperia internal revision code indicating final production release status.
How does the guard ring affect surge performance?
The integrated guard ring redistributes electric field concentration at the PN junction edge, increasing the device's ability to withstand repetitive 100 A/10 ms surges (per ISO 7637-2 Pulse 5a) without degradation. This extends operational life in alternator-load-dump scenarios common in 12 V automotive systems.
Can PMEG2010EA-QF replace a standard silicon diode in existing designs?
Yes, but only where reverse voltage ≤20 V and forward current ≤1 A. Due to its lower VF, it reduces conduction loss and thermal load - however, its higher reverse leakage (up to 50 µA) may affect precision analog sensing nodes. Layout must respect SOD323 pad geometry to avoid tombstoning.
