DESCRIPTION
The TSIxxB1 provides the diode bridge and the crowbar protection function that can be found in most of telecom terminal equipment.
Integrated monolithically within a SO8 package, this ASD device allows space saving on the board and greater reliability.
FEATURES
■ STAND-OFF VOLTAGE FROM 62V TO 265V
■ PEAK PULSE CURRENT : 30 A (10/1000 µs)
■ MAXIMUM DC CURRENT : IF = 0.2 A
■ HOLDING CURRENT :150 mA
BenefitS
■ Diode bridge for polarity guard and crowbar protection within one device.
■ Single chip for greater reliability
■ Reduces component count versus discrete solution
■ Saves space on the board
MAIN APPLICATION
Telecom equipment requiring combined protection against transient overvoltages and rectification by diode bridge :
■ Telephone set
■ Base station for cordless set
■ Fax machine
■ Modem
■ Caller Id equipment
■ Set top box
