Description:

The BS08D bilateral switch is a
silicon planar monolithic integrated
circuit with the electrical character­istics of a bilateral thyristor.The
device is designed to switch at 7
to 9 volts with a 0.01%/°C temper­ature coefficient and have excel­lently matched characteristics in
both directions.

Features:

□ Low Switching Voltage of

7 to 9 Volts

□ Excellent Switching Voltage

Temperature Characteristics
(0.01%/°C)

□ High Reliability Devices
□ Gate Electrode Facilitating

Switching Operation Control
and Synchronization.

Applications:

□ Trigger Circuits for Thyristor or

Triac, Oscillators, Timers

Ordering Information:

Example: Select the complete five
digit part number you desire from
the table - i.e.BS08D is a 175mA
Silicon Bilateral Switch.
