The BEP0080SB is a diacs trigger diode manufactured by Bourne and is part of their SMB (DO-214AA) RoHS series. It is an electronic part that is mainly used for triggering AC loads, such as relays or automotive lighting. Its small size and low forward voltage drop makes it suitable for use in a wide range of applications. It comes with an epoxy molding of 8mm (0.3in) that provides excellent heat dissipation and reliability. The BEP0080SB is a RoHS-compliant, surface-mount device that provides excellent noise immunity and is rated for a wide operating temperature range (-65°C to +150°C). It is easily soldered onto the board and provides reliable and repeatable triggering performance over a wide range of temperatures.
