Product details
Overview
PMEG2010EA-QZ 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 at 1 A) and qualified to AEC-Q101 for automotive use in voltage clamping and protection circuits.
For engineers reviewing the PMEG2010EA-QZ datasheet, PMEG2010EA-QZ pinout, PMEG2010EA-QZ application, or PMEG2010EA-QZ equivalent, key selection criteria include low VF performance under 1 A load, thermal resistance (220 K/W on 10×10 mm FR4), SOD323 package footprint compatibility, and AEC-Q101 qualification for under-hood electronics.
Technical Context
This Schottky diode employs a planar die structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability in transient-prone automotive environments. 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 ambient ranges from –55 °C to +150 °C. Reverse leakage remains below 50 µA at 15 V and 25 °C, while diode capacitance is 19–25 pF at 5 V and 1 MHz - critical for EMI-sensitive clamping applications.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage | 20 V - maximum blocking capability without breakdown in protection/clamping paths |
| Forward Current | 1 A continuous - supports power rail protection and signal-level rectification in compact automotive modules |
| Forward Voltage | 480–550 mV at 1 A - reduces conduction loss and self-heating in space-constrained PCB layouts |
| Reverse Leakage | 10–50 µA at 15 V - ensures low standby power loss in always-on vehicle subsystems |
| Diode Capacitance | 19–25 pF at 5 V - minimizes signal distortion in high-frequency clamping and ESD protection networks |
| Junction Temp Limit | 150 °C - enables operation near engine control units and ADAS sensor housings |
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 dense automotive PCBs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in reverse-biased clamping; polarity-sensitive for ESD/TVS function |
| 2 (A) | Anode | Connected to lower-potential reference (e.g., ground or signal return); defines forward conduction direction |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves ruggedness against EOS and improves long-term reliability in automotive transients |
| AEC-Q101 qualification | Validated for automotive-grade production use including temperature cycling, HTRB, and ESD testing |
| Ultra-low VF at 1 A | Enables efficient voltage clamping with <0.55 V drop, reducing heat generation in tight thermal envelopes |
| SOD323 footprint | Matches industry-standard 0805-equivalent land pattern for seamless integration into existing layouts |
Applications
| Automotive Power Rail Protection | USB Port ESD Clamping |
|---|---|
Use Scenario: Protecting 12 V battery-fed ECUs from load dump and ISO 7637-2 pulses. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed across supply rails to shunt surge energy. Use Value: Low VF minimizes voltage overshoot during clamping; AEC-Q101 rating ensures field reliability. | Use Scenario: Safeguarding USB 2.0 data lines against IEC 61000-4-2 contact discharge. IC Role / Device Role / Timing Role: Low-capacitance (19–25 pF) Schottky clamp between D+ and D− lines. Use Value: Fast response and low Cd preserve signal integrity up to 480 Mbps without jitter degradation. |
| DC-DC Converter Output Rectification | Low-Power Sensor Signal Conditioning |
Use Scenario: Secondary-side rectification in 5 V/1 A buck converter for infotainment modules. IC Role / Device Role / Timing Role: Synchronous rectifier replacement in low-voltage, high-efficiency SMPS designs. Use Value: 480–550 mV VF reduces conduction loss by >30% vs. standard silicon diodes, improving efficiency. | Use Scenario: Biasing and overvoltage protection for analog sensor outputs (e.g., pressure, temp). IC Role / Device Role / Timing Role: Low-leakage (≤50 µA) forward/reverse clamp limiting signal swing to safe ADC input range. Use Value: Sub-µA leakage at low bias preserves microamp-level sensor accuracy and battery life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-40TF | Higher VF (550–650 mV at 1 A); same SOD-323 package; no AEC-Q101 certification | Limited to industrial/commercial use; not validated for automotive temperature cycling or humidity testing | Acceptable for cost-sensitive non-automotive designs where AEC-Q101 is not mandated |
| SS12-AU | Lower IF rating (200 mA); larger SOD-123 package; VF = 500 mV at 200 mA | Not suitable for 1 A continuous loads; requires PCB area increase and layout revision | Only viable if system current is ≤200 mA and board space allows SOD-123 footprint change |
Compared with RB050M-40TF and SS12-AU, PMEG2010EA-QZ uniquely delivers AEC-Q101 compliance, 1 A capability in SOD323, and sub-550 mV VF - making it the only drop-in solution for automotive 12 V rail protection requiring zero footprint change and full qualification.

FAQ
Is PMEG2010EA-QZ pin-compatible with standard SOD323 Schottky diodes?
Yes - it uses the standard SOD323 (SC-76) outline with cathode (Pin 1) and anode (Pin 2) assignments matching JEDEC MO-203AA. Footprint dimensions (1.7 mm × 1.25 mm) and solder land patterns align with IPC-7351B generic SOD323 recommendations.
What is the maximum allowable peak forward surge current for PMEG2010EA-QZ?
The non-repetitive peak forward current (IFSM) is 5 A for an 8.3 ms half-sine wave at Tj(init) = 25 °C. This rating supports transient suppression in load-dump events per ISO 7637-2, provided thermal design limits junction temperature rise.
Does PMEG2010EA-QZ require derating above 25 °C ambient?
Yes - forward current must be linearly derated above 25 °C using Rth(j-a) = 220 K/W (10×10 mm FR4). At 85 °C ambient, maximum continuous IF drops to approximately 0.7 A to maintain Tj ≤ 150 °C under natural convection conditions.
Can PMEG2010EA-QZ be used in bidirectional ESD protection configurations?
No - it is a unidirectional Schottky diode. For bidirectional ESD clamping, two devices must be connected in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated TVS array like PESD5V0S1BA should be selected instead.
