Product details
Overview
PMEG2015EA from Nexperia is a planar Schottky barrier diode with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1.5 A forward current, featuring ultra-low forward voltage (560–660 mV @ 1.5 A) and AEC-Q101 qualification for automotive use in clamping and protection circuits.
For engineers reviewing the PMEG2015EA datasheet, PMEG2015EA pinout, PMEG2015EA application, or PMEG2015EA equivalent, key selection criteria include low VF performance under pulsed 1.5 A load, SOD323 package thermal resistance (Rth(j-sp) = 210 K/W), and AEC-Q101 qualification for automotive-grade reliability.
Technical Context
This Schottky diode uses a planar structure with an integrated guard ring to enhance ruggedness against electrical overstress and improve reverse leakage stability. Its low-barrier metal-semiconductor junction enables fast switching (no minority-carrier storage) and minimal forward conduction loss across ambient temperatures from –65 °C to 125 °C.
Thermal design is constrained by its SOD323 package: junction-to-solder-point resistance is 210 K/W on FR4 with single-sided copper, and junction-to-ambient is 450 K/W under standard mounting. Reverse recovery is effectively zero due to majority-carrier operation, supporting ultra-high-speed clamping in DC-DC and ESD protection paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability before breakdown; defines safe operating range in 12 V automotive rails and 5–15 V logic protection. |
| Forward Current (IF) | 1.5 A continuous - Sustained conduction capacity at Tsp ≤ 55 °C; supports high-duty-cycle clamp loads without derating. |
| Forward Voltage (VF) | 560–660 mV @ 1.5 A - Low conduction loss reduces power dissipation and self-heating in compact layouts. |
| Reverse Current (IR) | 10–50 mA @ 15 V - Leakage level impacts standby power in always-on protection circuits; specified under pulsed test conditions. |
| Diode Capacitance (Cd) | 19–25 pF @ 5 V - Enables high-frequency transient response in ESD and RF-coupled clamping applications. |
| Junction Temp Limit (Tj) | 125 °C - Maximum allowable junction temperature; sets thermal margin for solder-point-limited power dissipation. |
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 space-constrained PCBs and automated reflow assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Negative terminal; connects to higher-potential node during forward bias; solder pad serves as primary thermal path (Rth(j-sp) = 210 K/W). |
| 2 (A) | Anode | Positive terminal; ties to lower-potential node; electrically isolated from thermal mass; defines polarity for unidirectional clamping. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated guard ring | Improves surge robustness and stabilizes reverse leakage under voltage transients, critical for automotive load-dump immunity. |
| AEC-Q101 qualification | Validated for automotive discrete semiconductor stress testing including HTGB, HTRB, and temperature cycling - enables direct use in engine control and body electronics. |
| Ultra-low VF profile | 240–270 mV @ 10 mA and 480–550 mV @ 1 A - minimizes conduction loss across wide dynamic current range in battery-powered systems. |
| SOD323 footprint | 1.7 mm × 1.25 mm body with 1.3 mm pitch - compatible with high-density routing and 0201-class placement equipment; reduces board area vs. SOD123. |
Applications
| Automotive Power Rail Clamping | USB Port ESD Protection |
|---|---|
Use Scenario: Suppressing load-dump transients on 12 V vehicle power buses during alternator regulation faults. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between rail and ground; conducts only during overvoltage events ≥20 V.

IC Role / Device Role / Timing Role: Low-leakage (≤50 mA @ 15 V) front-end protection diode in 24 V industrial input modules. Use Value: Guard-ring-enhanced stability ensures consistent clamping threshold across temperature and lifetime, reducing calibration drift risk. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| ON Semiconductor NSS1C200MZ4T1G | Same SOD323 package; 20 V VR, 1.0 A IF, 600 mV VF @ 1 A - lower current rating and higher VF at 1.5 A. | Not rated for 1.5 A continuous; unsuitable for sustained clamp loads above 1 A. | Select when board space matches but peak current demand is ≤1.0 A and AEC-Q101 is not required. |
| Vishay VS-1EQH02-M3/84A | SOD123 package; 20 V VR, 1.5 A IF, 550 mV VF @ 1.5 A - larger footprint (3.7 mm × 1.7 mm), no AEC-Q101 certification. | Lacks automotive qualification; thermal resistance ~300 K/W - requires additional layout cooling for same power. | Select when AEC-Q101 is unnecessary and PCB real estate allows larger package for marginally lower VF. |
Compared with NSS1C200MZ4T1G and VS-1EQH02-M3/84A, PMEG2015EA uniquely combines AEC-Q101 qualification, 1.5 A continuous rating in SOD323, and guaranteed 560–660 mV VF - making it optimal for space-constrained automotive clamping where reliability and thermal density are prioritized.

FAQ
What is the maximum pulsed forward current rating for PMEG2015EA?
The PMEG2015EA supports 4.5 A repetitive peak forward current (IFRM) with 1 ms pulse width and 25% duty cycle, and 10 A non-repetitive peak forward current (IFSM) for 8 ms square-wave pulses. These ratings assume proper PCB thermal design per SOD323 mounting guidelines and are defined in accordance with IEC 60134 absolute maximum ratings.
Does PMEG2015EA require special PCB layout considerations for thermal performance?
Yes - optimal thermal performance requires maximizing copper area on the cathode (Pin 1) pad per Nexperia's SOD323 footprint recommendations: minimum 1 cm² tin-plated copper on FR4, with solder mask defined to expose full pad. Junction-to-solder-point resistance drops to 210 K/W only under these conditions; insufficient copper raises thermal resistance and limits safe operating current.
Is PMEG2015EA suitable for bidirectional ESD protection?
No - PMEG2015EA is a unidirectional Schottky diode. For bidirectional ESD protection (e.g., USB data lines), two devices must be connected in series opposition (anode-to-anode or cathode-to-cathode), leveraging its low capacitance (19–25 pF @ 5 V) and fast response. Standalone use provides only single-polarity clamping.
How does the guard ring affect reliability in automotive applications?
The integrated guard ring mitigates edge breakdown under high dv/dt and voltage overshoot, improving robustness against load-dump and jump-start transients. It stabilizes reverse leakage across temperature and time, directly supporting AEC-Q101 requirements for HTRB (high-temperature reverse bias) and HTGB (high-temperature gate bias) stress tests - critical for 15-year automotive service life.
