Product details
Overview
PMEG2015EH-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 PMEG2015EH-QX datasheet, PMEG2015EH-QX pinout, PMEG2015EH-QX application, or PMEG2015EH-QX equivalent, key selection criteria include its ultra-low VF performance, SOD123F package thermal resistance (Rth(j-sp) = 60 K/W), AEC-Q101 qualification, and 70 µA max reverse leakage at 20 V.
Technical Context
This Schottky diode uses a planar silicon structure with an integrated guard ring to enhance robustness against electrical overstress and improve reliability under repetitive surge conditions. Its low junction-to-solder-point thermal resistance (60 K/W) enables high-current operation on standard FR4 PCBs without heatsinking.
The device delivers stable forward conduction down to −40 °C and up to 150 °C junction temperature, with reverse leakage tightly controlled (≤70 µA at VR = 20 V, Tamb = 25 °C) and capacitance limited to 50 pF at 1 V reverse bias - critical for high-frequency switching efficiency.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 20 V - Maximum blocking capability for 12 V automotive rail protection and 5–12 V DC-DC secondary-side rectification. |
| Forward Current (IF) | 1.5 A continuous - Supports sustained load currents in compact power stages without derating below 55 °C solder point temperature. |
| Forward Voltage (VF) | 560 mV typ. at IF = 1.5 A - Reduces conduction loss by >30% vs. standard silicon diodes, improving efficiency in battery-powered and thermally constrained designs. |
| Reverse Leakage (IR) | 70 µA max at VR = 20 V - Minimizes standby power loss in always-on automotive modules and low-power IoT edge nodes. |
| Diode Capacitance (Cd) | 50 pF max at VR = 1 V, f = 1 MHz - Enables clean switching waveforms in >1 MHz synchronous buck converters with minimal ringing. |
| Junction Temperature (Tj) | 150 °C max - Allows operation in under-hood automotive environments and sealed industrial enclosures without active cooling. |
| Thermal Resistance (Rth(j-sp)) | 60 K/W - Enables 1.5 A operation with ≤90 °C temperature rise above solder point on standard FR4 with 1 cm² cathode pad. |
Pinout & Package
Encapsulated in the SOD123F surface-mount plastic package (2.6 mm × 1.6 mm × 1.1 mm), this two-terminal device features gull-wing leads optimized for reflow soldering and high-density PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (K) | Cathode | Connected to higher-potential node in reverse-biased blocking mode; carries full forward current during conduction; requires thermal pad area for heat dissipation. |
| 2 (A) | Anode | Connected to lower-potential node; serves as return path during forward conduction; electrically isolated from cathode except through Schottky junction. |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-low forward voltage | 560 mV typ. at 1.5 A - Directly reduces I²R losses and improves system efficiency in space-constrained 12 V automotive subsystems. |
| AEC-Q101 qualification | Qualified per Stress Test Qualification for Discrete Semiconductors - Validated for mission-critical automotive applications including body control modules and ADAS power supplies. |
| Integrated guard ring | Planar structure with embedded guard ring - Enhances ruggedness against ESD and transient overvoltage events without external clamping components. |
| SOD123F package | 2.6 mm × 1.6 mm footprint with 1.1 mm height - Enables high-density placement in portable electronics and automotive ECUs where board area is premium. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| RB055LAM-40TR | 40 V VR, 0.5 A IF, VF = 450 mV @ 0.5 A - Higher voltage rating but lower current capacity and smaller package (SOD-323). | Not suitable for 1.5 A continuous loads; better fit for signal-level protection or low-current bias rails. | Select only when VR margin >20 V is required and IF < 0.6 A; avoid in power-path roles. |
| SS12HE3/5BT | 20 V VR, 2 A IF, VF = 550 mV @ 2 A - Higher current rating but larger DO-214AC package (4.5 mm × 2.7 mm) and no AEC-Q101 qualification. | Lacks automotive qualification; thermal resistance ~100 K/W limits high-density layout viability. | Prefer for non-automotive 2 A applications where board space allows larger footprint and qualification is not mandated. |
Compared with RB055LAM-40TR and SS12HE3/5BT, PMEG2015EH-QX uniquely balances AEC-Q101 compliance, 1.5 A capability, ultra-low VF, and SOD123F miniaturization - making it the only option qualified for automotive-grade 12 V power rail protection in space-constrained modules.

FAQ
Is PMEG2015EH-QX suitable for synchronous rectification in DC-DC converters?
No - PMEG2015EH-QX is a passive Schottky rectifier, not a synchronous rectifier controller or MOSFET driver. It functions as a unidirectional conduction device and requires external gate control for true synchronous operation. Its 50 pF capacitance and low VF make it ideal as a freewheeling or output rectifier in non-synchronous topologies up to 1 MHz.
What is the maximum allowable soldering temperature profile for PMEG2015EH-QX?
The SOD123F package is rated for standard lead-free reflow per JEDEC J-STD-020. Peak temperature must not exceed 260 °C for ≤30 seconds, with ramp-up rate ≤3 °C/s and ramp-down rate ≤6 °C/s. Preheat (150–200 °C) duration should be 60–120 seconds to avoid thermal shock to the die or mold compound.
Does PMEG2015EH-QX have a specified avalanche energy rating?
No - As a Schottky barrier diode, PMEG2015EH-QX does not have an avalanche breakdown mode. Its absolute maximum reverse voltage is 20 V; operation beyond this risks immediate irreversible junction failure. Transient overvoltage protection must be implemented externally using TVS diodes or clamping circuits.
Can PMEG2015EH-QX replace a standard 1N5819 in existing designs?
Yes - With identical 20 V VR and 1.5 A IF ratings, plus lower VF (560 mV vs. ~450–600 mV for 1N5819 depending on batch), PMEG2015EH-QX offers improved efficiency and AEC-Q101 qualification. The SOD123F footprint differs from DO-41, so PCB layout revision is required; thermal performance is superior due to lower Rth(j-sp).
