The two-chip modified TO-220 MC SIDACtor® solid state device protects telecommunication equipment in applications that reference Tip and Ring to earth ground but do not require balanced protection. SIDACtor® devices are used to enable equipment to meet various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA-968 (formerly known as FCC Part 68).Notes: All measurements are made at an ambient temperature of 25°C. IPP applies to -40°C through +85°C temperature range. IPP is a repetitive surge rating and is guaranteed for the life of the product. Listed SIDACtor® devices are bi-directional. All electrical parameters and surge ratings apply to forward and reverse polarities. VDRM is measured at IDRM. VS is measured at 100 V/µs. Special voltage (VS and VDRM) and holding current (IH) requirements are available upon request. Off-state capacitance is measured between Pins 1-2 and 3-2 at 1MHz with a 2V bias.

This fixed voltage, unidirectional, modified DO-214 SIDACtor thyristor series is designed to protect SLICs (Subscriber Line Interface Circuit) from damaging overvoltage transients. These components provide single port protection implementing voltage switching characteristics for negative polarity surges and a clamping diode for positive polarity surges. All positive surges are routed through internal diodes to a ground reference. * Series resistance required

The Q2L SIDACtor® SLIC series provides unidirectional transient voltage protection in a low profile, Chip Scale Package (CSP). The small package QFN (Quad Flatpak No-Lead) is ideal for dense board applications that have multiple lines per card. The high density SLIC cards will benefit from this CSP technology by being able to fit more protection in a smaller PCB area.Protection solution to meet YD/T 950 YD/T 993 YD/T 1082 GR 1089 IEC 61000-4-5 ITU K.20/21 Basic/Enhanced TIA-968-A

These DO-214AA unidirectional protectors are constructed with a SIDACtor® device and an integrated diode. They protect SLICs (Subscriber Line Interface Circuits) from damage during transient voltage activity and enable line cards to meet various regulatory requirements including GR 1089, ITU K.20, K.21 and K.45, IEC 60950, UL 60950, and TIA/EIA-IS-968 (formerly known as FCC Part 68).Notes: All measurements are made at an ambient temperature of 25°C. Ipp applies to -40°C through +85°C temperature range. Ipp is a repetitive surge rating and is guaranteed for the life of the product. Listed SIDACtor devices are bi-directional. All electrical parameters & surge ratings apply to forward and reverse polarities. Vdrm is measured at Idrm. Vs is measured at 100V/µs. Special voltage (Vs & Vdrm) and holding current (Ih) requirements are available upon request. Off-state capacitance is measured at 1MHz with a 2V bias and is a typical value. Parallel capacitive loads may affect electrical parameters.
