Application Scenarios & Design Considerations

Overvoltage Protector Series BIDIRECTIONAL THYRISTOR OVERVOLTAGE PROTECTORS

Alternative Part Number

  • P3500SCLRP --: SIDACtor thyristor surge protector with similar 350V breakover and DO-214AA package, a common cross for TISP overvoltage protectors.
  • P3500SBLRP --: Same SIDACtor family with 350V breakover in SMB package, suitable drop-in replacement for telecom surge protection.
  • TISP4350H3BJR-S --: Bourns TISP series variant with equivalent 350V rating and SMB package, closest electrical match from the same manufacturer.
