Product details
Overview
PMEG2015EJ-QX from Nexperia is a planar Schottky barrier rectifier with integrated guard ring for stress protection, rated at 20 V reverse voltage and 1.5 A forward current, featuring a typical forward voltage of 560 mV at 1.5 A and qualified to AEC-Q101 for automotive use in low-voltage DC-DC converters and polarity protection circuits.
For engineers reviewing the PMEG2015EJ-QX datasheet, PMEG2015EJ-QX pinout, PMEG2015EJ-QX application, or PMEG2015EJ-QX equivalent, key selection criteria include its ultra-low VF (≤660 mV), AEC-Q101 qualification, SOD323F package thermal resistance (Rth(j-sp) = 55 K/W), and 70 µA max reverse leakage at 20 V.
Technical Context
This Schottky diode employs a planar junction structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability under repetitive surge conditions. Its low barrier height enables minimal forward conduction loss while maintaining acceptable reverse leakage up to 20 V.
The device operates with a maximum junction temperature of 150 °C and exhibits thermal resistance of 55 K/W from junction to solder point on FR4 PCB with 1 cm² cathode pad - critical for thermally constrained automotive body control modules and infotainment power rails.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - defines maximum blocking capability in reverse-biased applications like reverse polarity protection. |
| Forward Current (IF) | 1.5 A continuous - supports compact 12 V/5 V DC-DC output stages without forced cooling. |
| Forward Voltage (VF) | 560 mV typ. at 1.5 A - reduces conduction loss by >30% vs. standard silicon diodes in high-efficiency buck converters. |
| Reverse Leakage (IR) | 70 µA max at VR = 20 V - ensures low standby power in always-on automotive subsystems. |
| Diode Capacitance (Cd) | 50 pF max at VR = 1 V - minimizes switching noise and improves EMI performance in high-frequency SMPS. |
| Junction Temperature (Tj) | 150 °C max - enables operation in under-hood environments without derating below 1.5 A. |
| Thermal Resistance (Rth(j-sp)) | 55 K/W - allows direct thermal coupling to PCB copper, simplifying thermal design in space-constrained modules. |
Pinout & Package
Encapsulated in the SOD323F (SC-90) package: 1.7 mm × 1.25 mm × 0.7 mm body, flat lead surface-mount outline with gull-wing terminations optimized for reflow soldering and automated assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in forward conduction; primary heat path to PCB via cathode pad. |
| 2 (A) | Anode | Connected to lower-potential node; carries full forward current with minimal parasitic inductance due to short internal bond. |
Key Features
| Feature | Design Value |
|---|---|
| Guard ring integration | Improves ruggedness against ESD and transient overvoltage without increasing VF or package size. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD (HBM ≥ 2 kV). |
| Ultra-low VF profile | 560–660 mV at 1.5 A enables >95% efficiency in 5 V synchronous rectifier replacement designs. |
| SOD323F footprint | Standardized 0.5 mm pitch, 1.15 mm pad length - compatible with high-volume pick-and-place and AOI inspection. |
Applications
| Automotive Body Control Module | USB-C Power Delivery Clamp |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB050M-30 | Higher VF (750 mV typ. @ 1.5 A); same 20 V VR; TO-236AB package (larger footprint, higher Rth(j-a)) | Less suitable for thermally dense automotive modules; better for cost-sensitive industrial supplies with board space margin | Select when PCB layout permits larger 2.9 mm × 1.3 mm footprint and thermal budget allows 350 K/W Rth(j-a) |
| SS12 | Same SOD-123 package; 20 V VR; 1.2 A IF rating; VF = 500 mV typ. @ 1 A; no AEC-Q101 qualification | Not recommended for automotive production; acceptable for consumer-grade 5 V adapters or prototyping | Choose only for non-automotive prototypes where AEC-Q101 compliance is not required and 1.2 A current limit is sufficient |
Compared with RB050M-30 and SS12, PMEG2015EJ-QX delivers superior thermal performance in minimal area, AEC-Q101 assurance for automotive deployment, and tighter VF consistency across temperature - making it optimal for space- and reliability-critical 12–24 V embedded power rails.

FAQ
Is PMEG2015EJ-QX suitable for synchronous rectification in DC-DC converters?
No - PMEG2015EJ-QX is a unidirectional Schottky rectifier, not a synchronous rectifier IC or MOSFET driver. It functions as a passive freewheeling or clamp diode. For synchronous rectification, a dedicated gate driver paired with a low-RDS(on) MOSFET is required; this diode serves best as a simple, robust, low-VF alternative where active control is unnecessary or cost-prohibitive.
What is the maximum allowable PCB copper area for the cathode pad to achieve the 55 K/W Rth(j-sp)?
The 55 K/W thermal resistance is measured with a 1 cm² tin-plated copper pad on FR4 PCB, single-sided, using the standard SOD323F footprint per Nexperia's Figure 5. Increasing pad area beyond 1 cm² yields diminishing returns; reducing below 0.8 cm² increases Rth(j-sp) nonlinearly - design verification with IR imaging is recommended for pads <0.5 cm².
Does the "EL" marking on the device correspond to PMEG2015EJ-QX?
Yes - per Table 4 of the datasheet, the marking code "EL" is assigned exclusively to the PMEG2015EJ-QX type number. This two-character laser mark appears on the top surface of the SOD323F package and is verified under 20× magnification during final test and packaging.
Can PMEG2015EJ-QX replace a 1N5819 in an existing design?
Yes, with caveats: both are 20 V/1 A Schottky diodes, but PMEG2015EJ-QX offers 1.5 A rating, lower VF (560 mV vs. ~450–600 mV depending on batch), AEC-Q101 qualification, and SOD323F package (vs. DO-41). Layout redesign is required for the smaller footprint, and thermal validation is needed due to different Rth(j-sp) characteristics.
