MicroCapacitance (MC) SIDACtor Device MicroCapacitance (MC) SIDACtor Device The TO-92 MC SIDACtor series is intended for applications sensitive to load values. Typically, high speed connections require a lower capacitance. CO values for MC devices are 40% lower than a standard EC part. This MC SIDACtor series is 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-A (formerly known as FCC Part 68) without the need of series resistors.

General 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 (CO) is measured at 1 MHz with a 2 V bias.
