SMCJ85A Description

Short technical summary and product information.

The SMCJ85A is a unidirectional TVS diode from the SMCJ series, designed to protect sensitive electronic equipment from voltage transients induced by lightning and other transient voltage events. It offers a peak pulse power dissipation of 1500W (1.5kW) for a 10/1000µs waveform, making it suitable for general-purpose circuit protection applications.

 

Key electrical specifications include a reverse standoff voltage of 85V and a maximum clamping voltage of 137V at a peak pulse current of 11A. The device is surface mountable and comes in a DO-214AB (SMC) package, with an operating temperature range of -55°C to 150°C. It is designed for unidirectional protection with a single channel.

 

The SMCJ85A is suitable for use in telecom, computer, industrial, and consumer electronic applications where protection of I/O interfaces and VCC buses is required. The device features a glass passivated chip junction and is designed for high temperature reflow soldering up to 260°C.
