Three quadrant triacs BTA208B series D, E and F
guaranteed commutation
GENERAL DESCRIPTION QUICK REFERENCE DATA
Glass passivated high commutation SYMBOL PARAMETER MAX. MAX. MAX. UNIT
triacs in a plastic envelope suitable for
surface mounting, intended for use in BTA208B- 500D 600D -
motor control circuits or with other BTA208B- 500E 600E 800E
highly inductive loads. These devices BTA208B- 500F 600F 800F
balance the requirements of VDRM Repetitive peak off-state 500 600 800 V
commutation performance and gate voltages
sensitivity. The "sensitive gate" E IT(RMS) RMS on-state current 8 8 8 A
series and "logic level" D series are ITSM Non-repetitive peak on-state 65 65 65 A
intendedfor interfacingwith lowpower current
drivers, including micro controllers.
