Protector
The DO-214AA SIDACtor Ethernet protection series is intended for applications sensitive to
load values. Typically, high speed connections require a lower capacitance. CO values are
40% lower than standard devices.
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-A
(formerly known as FCC Part 68).
* For surge ratings, see table below.
** Contact factory for release date.
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.
