SMCJ12A Description

Short technical summary and product information.

The Bourns SMCJ12A is a unidirectional transient voltage suppressor diode designed to protect sensitive electronic circuits from voltage transients induced by lightning, inductive load switching, and electrostatic discharge. It features a reverse standoff voltage of 12 V and a clamping voltage of 19.9 V, ensuring rapid clamping of overvoltage events.

 

With a peak pulse power dissipation of 1500 W and a peak pulse current rating of 75.4 A, this device provides robust surge protection. The response time is less than 1.0 picosecond from 0 V to the minimum breakdown voltage, making it suitable for high-speed signal lines.

 

The SMCJ12A is housed in a DO-214AB (SMC) surface mount package, which is compatible with standard pick-and-place equipment. It operates over a junction temperature range of -55°C to +150°C and has a maximum steady-state power dissipation of 5.0 W at a lead temperature of 75°C.
