For non-RoHS compliant device, delete “L” from part number. For surge ratings, see table below. 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.
