Product details
Overview
PMEG2015EA-QX 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 qualified to AEC-Q101 for automotive power rail clamping and ESD-sensitive signal line protection.
For engineers reviewing the PMEG2015EA-QX datasheet, PMEG2015EA-QX pinout, PMEG2015EA-QX application, or PMEG2015EA-QX equivalent, key selection criteria include its SOD323 package thermal resistance (Rth(j-sp) = 210 K/W), low 19–25 pF junction capacitance at 5 V, and pulsed reverse leakage performance (≤50 mA @ 15 V).
Technical Context
This discrete Schottky diode uses a planar silicon structure with an integrated guard ring to enhance robustness against electrical overstress and transient voltage events in automotive power domains. Its ultra-low VF enables high-efficiency DC-DC output rectification and low-loss voltage clamping in 12 V systems.
The device operates with junction temperatures up to 125 °C and supports repetitive peak forward currents of 4.5 A (1 ms pulse) and non-repetitive surges up to 10 A (8 ms square wave), making it suitable for load dump and ISO 7637-2 transient suppression circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum continuous blocking voltage in automotive 12 V battery systems with margin for load dump transients. |
| Forward Current (IF) | 1.5 A - Continuous DC current rating at Tsp ≤ 55 °C; defines usable current capacity in compact space-constrained PCB layouts. |
| Forward Voltage (VF) | 560–660 mV @ 1.5 A - Enables <1.0 W conduction loss at full rated current, critical for thermally constrained modules. |
| Reverse Leakage (IR) | 10–50 mA @ 15 V - Confirmed pulsed measurement; informs design margin for voltage clamp hold-off in protection circuits. |
| Junction Capacitance (Cd) | 19–25 pF @ 5 V, 1 MHz - Low capacitance preserves signal integrity in high-speed data line protection (e.g., LIN bus, CAN FD stubs). |
| Thermal Resistance (Rth(j-sp)) | 210 K/W - Measured from junction to solder point on FR4; enables accurate thermal modeling for SMT pad layout and reliability prediction. |
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 tin-plated terminations.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Cathode (K) | Connected to higher-potential node in reverse-biased protection configuration; primary thermal path to PCB via cathode pad. |
| 2 | Anode (A) | Connected to lower-potential node (e.g., ground or return path); carries forward current during clamping or rectification. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Enhances ESD and surge immunity by preventing edge breakdown; validated per AEC-Q101 HBM and CDM test requirements. |
| AEC-Q101 qualification | Qualified for automotive under stress test conditions including temperature cycling, HTGB, and uHAST - supports Tier-1 production use without requalification. |
| Ultra-high-speed switching | Sub-nanosecond reverse recovery (trr not specified but implied by Schottky architecture and 25 pF Cd); eliminates switching losses in >1 MHz DC-DC topologies. |
| Low-profile SMD package | SOD323 footprint occupies only 2.125 mm² board area - enables placement adjacent to connectors or IC pins in ADAS sensor modules and body control units. |
Applications
| Automotive Power Rail Clamping | LIN Bus Transient Protection |
|---|---|
Use Scenario: Suppresses load dump spikes (ISO 7637-2 Pulse 5a) on 12 V supply rails feeding infotainment head units. IC Role / Device Role / Timing Role: Unidirectional voltage clamp placed between battery input and downstream LDO/regulator input. Use Value: Limits transient overshoot to <24 V using 20 V VR rating and low dynamic impedance, preventing regulator latch-up. |
Use Scenario: Protects LIN transceiver I/O pins from ESD (IEC 61000-4-2 ±8 kV contact) and coupled noise in door module wiring harnesses. IC Role / Device Role / Timing Role: Bidirectional clamping diode pair (with complementary device) referenced to VBAT and GND. Use Value: 19–25 pF capacitance avoids signal rise/fall time degradation on 20.2 kbps LIN bus while maintaining <100 ns response. |
| USB-C Port Overvoltage Protection | DC-DC Converter Output Rectification |
Use Scenario: Prevents damage to USB-C port controller ICs during hot-plug events where VBUS exceeds 5.5 V due to source negotiation failure. IC Role / Device Role / Timing Role: Forward-biased crowbar diode shunting excess voltage to system ground when triggered by external supervisor. Use Value: 560–660 mV VF ensures minimal voltage drop during normal operation and fast activation (<10 ns) during overvoltage. |
Use Scenario: Synchronous rectifier replacement in 5 V/3 A buck converter for automotive telematics power supply. IC Role / Device Role / Timing Role: Low-VF freewheeling diode in non-synchronous topology operating at 500 kHz switching frequency. Use Value: Reduces conduction loss by 40% versus standard PN diodes, lowering thermal load on 2-layer FR4 PCB with limited copper area. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-1EQH02-M3/86A | 20 V VR, 1.5 A IF, VF = 550 mV typ @ 1.5 A; SOD-123 package (larger footprint, Rth(j-a) = 500 K/W) | Higher thermal resistance limits use in sealed enclosures above 60 °C ambient; requires larger PCB pad for thermal relief. | Select when legacy SOD-123 footprint compatibility is required and board-level thermal management allows higher junction rise. |
| ON Semiconductor NSR20F20NXT5G | 20 V VR, 2.0 A IF, VF = 520 mV typ @ 2 A; same SOD323 package; AEC-Q101 qualified | Higher current rating enables derated operation for extended lifetime in high-reliability engine control modules. | Prefer for new designs requiring margin on IF or lower VF, especially where 2 A surge capability improves robustness against cranking transients. |
Compared with VS-1EQH02-M3/86A, PMEG2015EA-QX offers 30% lower thermal resistance and smaller footprint; versus NSR20F20NXT5G, it trades 0.5 A IF margin for tighter VF consistency across temperature and lower unit cost in high-volume automotive procurement.

FAQ
Is PMEG2015EA-QX suitable for bidirectional ESD protection?
No - PMEG2015EA-QX is a unidirectional Schottky diode with cathode and anode terminals. For bidirectional ESD protection (e.g., USB or CAN lines), it must be used in conjunction with a complementary diode or as part of a dedicated TVS array. Its guard ring enhances unidirectional surge handling but does not provide symmetrical clamping.
What is the maximum allowable soldering temperature profile for PMEG2015EA-QX?
The device complies with JEDEC J-STD-020D reflow guidelines for MSL1 components. Peak reflow temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Figure 5 in the datasheet specifies the recommended SOD323 reflow footprint with 0.5 mm solder mask defined lands.
Does PMEG2015EA-QX have a specified reverse recovery time (trr)?
No - as a Schottky barrier diode, PMEG2015EA-QX has no minority carrier storage and therefore no defined trr. Its switching is governed by junction capacitance (19–25 pF) and series resistance, enabling effective operation at frequencies exceeding 100 MHz in clamping applications.
Can PMEG2015EA-QX replace a standard 1N5819 in automotive designs?
Yes - with caveats. While both are 20 V/1 A Schottky diodes, PMEG2015EA-QX offers AEC-Q101 qualification, lower VF (560–660 mV vs. ~750 mV), and SOD323 packaging versus DO-41. It is a direct functional upgrade but requires PCB footprint revision and validation of thermal performance in the target application.
