Product details
Overview
PMEG2010EA-QX from Nexperia is a 20 V, 1 A planar Schottky barrier diode with integrated guard ring for stress protection, housed in an SOD323 (SC-76) package. It delivers ultra-low forward voltage (480–550 mV at 1 A), ultra-high-speed switching, and AEC-Q101 qualification-enabling use in automotive power rail clamping and ESD-sensitive signal path protection.
For engineers reviewing the PMEG2010EA-QX datasheet, PMEG2010EA-QX pinout, PMEG2010EA-QX application, or PMEG2010EA-QX equivalent, key selection criteria include its low VF performance at 1 A, 150 °C junction rating, 220 K/W thermal resistance on 10×10 mm FR4, and cathode/anode terminal assignment in the SOD323 footprint.
Technical Context
This discrete Schottky diode uses a planar silicon structure with an integrated guard ring to suppress edge breakdown under transient stress-critical for automotive load-dump and ISO 7637-2 pulse immunity. Its low barrier height enables sub-550 mV conduction at rated DC current while maintaining <50 µA reverse leakage at 15 V.
Thermal design requires attention to PCB copper area: Rth(j-a) drops from 220 K/W (10×10 mm) to 180 K/W (40×40 mm), and thermal runaway must be evaluated due to voltage-dependent reverse power loss (PR) contribution to total dissipation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Forward Voltage (VF) | 480–550 mV at 1 A, 25 °C - enables <0.55 W conduction loss in 12 V automotive rails |
| Reverse Voltage (VR) | 20 V maximum - supports 12 V nominal systems with 100 % margin against ISO 16750-2 load dump transients |
| Reverse Current (IR) | 10–50 µA at 15 V, 25 °C - ensures minimal standby power drain in always-on vehicle modules |
| Diode Capacitance (Cd) | 19–25 pF at 5 V, 1 MHz - suitable for high-frequency clamping without signal integrity degradation |
| Junction Temperature (Tj) | 150 °C maximum - allows operation in engine bay environments with derated current above 85 °C ambient |
| Thermal Resistance (Rth(j-a)) | 220 K/W on 10×10 mm FR4 - defines minimum PCB copper area needed for 1 A continuous operation |
Pinout & Package
Encapsulated in the SOD323 (SC-76) surface-mount plastic package: 1.7 mm × 1.25 mm × 0.95 mm body, 1.3 mm lead pitch, single-sided copper mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Negative terminal; connects to system ground or lower-potential node during clamping |
| 2 | Anode (A) | Positive terminal; ties to protected line (e.g., CAN bus, sensor supply, MCU I/O) |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Suppresses edge breakdown under repetitive surge stress-extends lifetime in automotive transients |
| AEC-Q101 qualification | Validated for automotive-grade reliability including HTGB, HTRB, and temperature cycling per Q101-004 |
| Ultra-low VF at 1 A | Reduces forward power loss by >30 % vs. standard Schottkys (e.g., PMEG3010CEH), improving thermal margin |
| SOD323 footprint | Enables high-density layout in space-constrained ECUs and ADAS sensor modules without rework risk |
Applications
| Automotive Power Rail Clamping | CAN Bus Transient Protection |
|---|---|
Use Scenario: Suppressing load dump spikes (ISO 16750-2 Pulse 5a) on 12 V battery-fed ECUs. IC Role / Device Role / Timing Role: Unidirectional voltage clamp placed between VBAT and ground. Use Value: Limits peak rail voltage to ≤20 V using inherent Schottky VR, avoiding TVS crowbar activation and system reset. |
Use Scenario: Protecting high-speed CAN FD transceivers from ESD (IEC 61000-4-2) and coupled noise. IC Role / Device Role / Timing Role: Low-capacitance shunt diode across CANH/CANL differential pair. Use Value: 19–25 pF capacitance preserves signal edge integrity up to 5 Mbps while clamping ±15 kV contact discharge. |
| Low-Power Sensor Supply Protection | USB Port Overvoltage Clamp |
Use Scenario: Preventing reverse polarity damage and backfeed in 3.3 V/5 V sensor supply lines. IC Role / Device Role / Timing Role: Series blocking diode or reverse-biased clamp at LDO input. Use Value: 480 mV VF minimizes dropout in low-voltage rails, preserving headroom for precision analog sensors. |
Use Scenario: Safeguarding USB 2.0 data lines and VBUS against hot-plug overshoot and adapter faults. IC Role / Device Role / Timing Role: Bidirectional clamp (anode-to-ground, cathode-to-line) on D+/D− or VBUS. Use Value: Sub-550 mV forward drop avoids false VBUS undervoltage detection; 20 V rating covers 5 V ±10 % tolerance plus margin. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PMESD1CAN-Q | Integrated dual-channel ESD protection + Schottky clamp; higher Cd (35 pF), lower IF (0.3 A) | Optimized for CAN FD compliance; includes IEC 61000-4-2 Level 4 ESD protection | Select when combined ESD + clamping is required and 300 mA current suffices |
| RB055LAM-40TR | Higher VR (40 V), higher VF (620 mV @1 A), same SOD-323 package | Targets 24 V industrial systems; less suitable for 12 V automotive due to excess VF loss | Select for 24 V applications needing wider reverse margin and accepting higher conduction loss |
Compared with PMEG2010EA-QX, PMESD1CAN-Q adds certified ESD protection but sacrifices current handling and speed; RB055LAM-40TR trades low VF for higher reverse rating-making it viable only where 24 V operation and thermal margin outweigh efficiency needs.

FAQ
Is PMEG2010EA-QX suitable for bidirectional transient suppression?
No-PMEG2010EA-QX is a unidirectional Schottky diode with anode and cathode terminals. For bidirectional clamping (e.g., on differential lines), two devices must be used in series-opposed configuration or a dedicated bidirectional TVS/ESD device selected. Its guard ring and low VF are optimized for forward conduction, not reverse avalanche.
What is the maximum continuous forward current at 105 °C ambient?
At Tamb = 105 °C, the maximum continuous forward current is derated to approximately 0.65 A based on thermal resistance (220 K/W) and Tj(max) = 150 °C. This assumes a 10×10 mm FR4 PCB; increasing copper area improves current capability proportionally per the 180 K/W rating on 40×40 mm.
Does the SOD323 package support automated optical inspection (AOI)?
Yes-the SOD323 package has standardized dimensions (1.7 × 1.25 × 0.95 mm) and visible anode/cathode markings (E1 code), enabling reliable AOI detection of placement orientation and solder joint quality in high-volume automotive PCB assembly lines.
How does the guard ring affect surge current handling?
The integrated guard ring prevents premature edge breakdown during repetitive surge events (e.g., ISO 7637-2 pulses), allowing the diode to sustain its full 5 A non-repetitive peak forward current (IFSM) without localized thermal runaway-verified under AEC-Q101 stress testing protocols.
