Product Overview

The SMCJ15A is a unidirectional surface-mount transient voltage suppressor (TVS) diode designed for protecting sensitive electronic devices. It effectively shields circuits from voltage transients caused by lightning, ESD, and other transient events. With a 1500W peak pulse power capability and excellent clamping performance, it rapidly responds to voltage surges, ensuring stable circuit operation in space-constrained PCB designs.

Key Features

• High-Efficiency Surge Protection: Handles 1500W peak pulse power at 10/1000μs waveform, ideal for non-repetitive transient overvoltage events.
• Precise Clamping Performance: Low incremental surge resistance and fast response time (typically <1.0ps) limit voltage spikes, reducing equipment damage risks.
• Low Leakage Current Design: Typical reverse leakage current (IR) is less than 1μA when the minimum breakdown voltage >12V, enhancing circuit efficiency and reliability.
• Compact Surface-Mount Package: Uses a low-profile DO-214AB package to optimize board space, suitable for high-density surface-mount technology.
• Wide Temperature Range & Compliance: Operates from -65°C to 150°C, with UL V-0 flammability rating, RoHS compliance, and halogen-free design for harsh environments and environmental standards.

Technical Specifications

Typical Applications

• Telecom Equipment: Protects I/O interfaces and power buses from surges, ensuring stable signal transmission.
• Computer Systems: Safeguards USB, HDMI, and other data ports against ESD and EFT, preventing data corruption.
• Industrial Control: Shields sensor and controller circuits in harsh electromagnetic environments, enhancing anti-interference capabilities.
• Consumer Electronics: Protects charging interfaces and RF circuits in smartphones and tablets from daily ESD and voltage fluctuations.
• Automotive Electronics: Meets voltage transient protection needs in high-temperature environments, suitable for in-vehicle communication and entertainment systems.

Why Choose SMCJ15A？

• Superior Protection Capability: 1500W peak power and fast response effectively suppress transient overvoltages.
• Space-Optimized Design: Surface-mount package saves board space for miniaturized device integration.
• High Reliability: Glass-passivated chip junction and built-in strain relief reduce long-term failure risks.
• Harsh Environment Adaptability: Wide temperature range and MSL Level 1 certification support high-temperature reflow soldering (260°C/30s) and harsh environments.
• Compliance & Safety: RoHS, halogen-free, and UL V-0 compliant, meeting global environmental and safety standards.
