Product details
Overview
PMEG3015EJ-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 30 V reverse voltage and 1.5 A forward current, featuring ultra-low 440–550 mV forward voltage at 1.5 A, housed in SOD323F (SC-90) package, and qualified to AEC-Q101 for automotive-grade reliability in low-voltage DC/DC conversion and polarity protection circuits.
For engineers reviewing the PMEG3015EJ-QX datasheet, PMEG3015EJ-QX pinout, PMEG3015EJ-QX application, or PMEG3015EJ-QX equivalent, key selection criteria include its 440–550 mV VF at 1.5 A, 60–150 µA IR at 10 V, 60–72 pF capacitance at 1 V, AEC-Q101 qualification, and SOD323F thermal resistance of 150 K/W (junction-to-solder point).
Technical Context
This Schottky diode employs a planar silicon structure with an integrated guard ring to suppress edge breakdown under high dv/dt or surge stress, enabling stable operation in automotive transients. Its ultra-low VF minimizes conduction loss in high-frequency switching paths where efficiency below 1 V drop is critical.
The device operates with junction temperatures up to 150 °C and supports repetitive peak forward current up to 4.5 A (tp ≤ 1 ms), while its 60–72 pF capacitance at 1 V reverse bias ensures minimal switching loss in 1–10 MHz DC/DC topologies. Thermal performance is specified for FR4 PCB mounting with defined pad area per JEDEC standards.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 30 V - Maximum blocking capability without avalanche breakdown; suitable for 24 V automotive rail clamping and 12 V system rectification. |
| Forward Current (IF) | 1.5 A continuous - Rated for sustained conduction at ambient ≤55 °C on standard FR4 PCB; supports compact power stage designs. |
| Forward Voltage (VF) | 440–550 mV at 1.5 A - Enables >95% conduction efficiency in low-VIN buck converters and reduces thermal load vs. standard silicon diodes. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| Vishay VS-1EQH03-M3/86A | 30 V VR, 1.0 A IF, VF = 450 mV @ 1 A; SOD-123FL package; no AEC-Q101 qualification. | Limited to commercial-temperature industrial use; lacks automotive stress validation and 1.5 A current headroom. | Select when cost sensitivity outweighs AEC-Q101 requirement and 1.5 A derating is acceptable. |
| ON Semiconductor NSR1030HT1G | 30 V VR, 1.0 A IF, VF = 420 mV @ 1 A; SOD-123 package; AEC-Q101 qualified. | Lower IF rating restricts use to ≤1 A loads; smaller 1.3 mm × 0.9 mm footprint but higher Rth(j-a) (350 K/W). | Prefer only if board space is tighter than 1.7 mm × 1.25 mm and load current remains ≤1.0 A. |
Compared with VS-1EQH03-M3/86A and NSR1030HT1G, PMEG3015EJ-QX uniquely delivers 1.5 A continuous current with AEC-Q101 qualification in SOD323F, offering superior thermal performance (150 K/W Rth(j-sp)) and verified robustness for automotive transients-making it the only choice for 12 V/24 V systems requiring full-rated conduction and long-term reliability.

FAQ
What is the maximum allowable junction temperature for PMEG3015EJ-QX?
The absolute maximum junction temperature is 150 °C, as defined in the Limiting Values table. Operation above this threshold risks permanent parametric shift or catastrophic failure. Derating curves in the datasheet show that at Tamb = 85 °C, the device supports ≤1.0 A continuous forward current on standard FR4 PCB with 1 cm² cathode pad.
Does PMEG3015EJ-QX support bidirectional current flow?
No. It is a unidirectional Schottky rectifier: current flows only from anode to cathode under forward bias. Reverse conduction is blocked up to 30 V, with leakage limited to 60–150 µA at 10 V and 400–1000 µA at 30 V. It cannot function as a bidirectional switch or symmetrical clamp.
How does the SOD323F package affect thermal performance compared to SOD-123?
SOD323F offers lower junction-to-solder-point thermal resistance (150 K/W vs. ~250–350 K/W for typical SOD-123) due to optimized cathode pad geometry and shorter internal thermal path. This allows 30–40% higher power dissipation before reaching Tj = 150 °C under identical PCB layout conditions.
Is the marking code 'EK' sufficient to identify PMEG3015EJ-QX on the physical device?
Yes. Per Table 4 of the datasheet, 'EK' is the sole marking code for PMEG3015EJ-QX. The cathode is indicated by a bar adjacent to pin 1, and the 'EK' marking appears on the top surface of the SOD323F package. No secondary codes or date codes are required for identification.
