SMCJ17A Description

Short technical summary and product information.

The SMCJ17A is a unidirectional TVS (Transient Voltage Suppression) diode designed for protecting sensitive electronic circuits from voltage transients. It offers a peak pulse power of 1500W (10/1000µs waveform) with a reverse standoff voltage of 17V and a maximum clamping voltage of 27.6V at 54.4A peak pulse current. This device is suitable for general purpose applications and is not intended for power line protection.

 

The SMCJ17A is housed in a DO-214AB (SMC) surface mount package, making it suitable for automated assembly. It operates over a temperature range of -55°C to 150°C. The part is halogen free and lead-free (Pb-free E3) as verified by the datasheet. Note: The datasheet provided is for the general SMCJ series; the specific datasheet for SMCJ17A should be verified for exact parameters.

 

Typical applications include I/O interface protection, VCC bus protection, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics. The device has a fast response time of less than 1.0ps and meets IEC 61000-4-2 ESD requirements.
