STMicroelectronics | SMTPA68

The SMTPA68 is a SMTPA Series of 150 mA 68 V Bidirectional Protecting Trisil SMT - DO-214AA. These Trisil series have been designed to protect telecommunication equipment against lightning and transient induced by AC power lines. They are available in SMA, SMB and DO-15 packages.

Features:

• Bidirectional crowbar protection
• Voltage range from 62 V to 320 V
• Low capacitance from 12 pF to 20 pF @ 50 V
• Low leakage current : IR = 2 μA max
• Holding current: IH = 150 mA min
• Repetitive peak pulse current :
  • IPP = 50 A (10/1000 μs)

Main applications:

• Telecommunication equipment such as:
• Analog and digital line cards (xDSL, T1/E1,ISDN, ...)
• Terminals (phone, fax, modem, ...) and central office equipment
