SMCJ12A Description

Short technical summary and product information.

The Littelfuse Inc. SMCJ12A is a 1500W TVS Diode designed for the protection of I/O interfaces, VCC bus, and other vulnerable circuits. It is ideal for applications requiring protection from lightning-induced voltage transients and other transient voltage events.

 

This surface mount device, packaged in a DO-214AB (SMCJ) case, offers a standoff voltage of 12V and a clamping voltage of 19.9V at 75.4A. It boasts a fast response time of typically less than 1.0ps and excellent clamping capability with low incremental surge resistance.

 

The SMCJ series is suitable for general-purpose applications and operates over a wide temperature range of -55°C to 150°C. It meets MSL level 1 requirements and is RoHS compliant, making it a reliable choice for various electronic systems.

 

Key electrical characteristics include a peak pulse power dissipation of 1500W at a 10/1000μs waveform, and ESD protection up to 30kV (Air and Contact) per IEC 61000-4-2. The device also offers EFT protection for data lines in accordance with IEC 61000-4-4.
