Bourns SMBJ18CA Transient Voltage Suppressor Diode

The SMBJ series Transient Voltage Suppressor Diode is designed for surge and electrostatic discharge (ESD) protection applications. It supports a working peak reverse voltage range from 5V to 495V and has a breakdown voltage up to 550V. The diode features rapid response times, less than 1 picosecond for unidirectional devices and less than 5 picoseconds for bidirectional devices, from 0V to the minimum breakdown voltage. It complies with JEDEC standards, offers easy handling with standard pick-and-place equipment, and has a flat configuration to minimize roll-away. The device can dissipate up to 600W and operates within a temperature range of -55°C to 150°C. Typical applications include communications and networking, computers and peripherals, imaging, video and vision systems, and industrial use.
