pxxx3u_ Series - Baseband Voice DS1 Protection from SIDACtor Protection Thyristors

Littelfuse products are not designed for, and shall not be used for, any purpose (including, without limitation, automotive, military, aerospace, medical, life-saving, life-sustaining or nuclear facility applications, devices intended for surgical implant into the body, or any other application in which the failure or lack of desired operation of the product may result in personal injury, death, or property damage) other than those expressly set forth in applicable Littelfuse product documentation. Warranties granted by Littelfuse shall be deemed void for products used for any purpose not expressly set forth in applicable Littelfuse documentation. Littelfuse shall not be liable for any claims or damages arising out of products used in applications not expressly intended by Littelfuse as set forth in applicable Littelfuse documentation. The sale and use of Littelfuse products is subject to Littelfuse Terms and Conditions of Sale, unless otherwise agreed by Littelfuse. "Littelfuse" includes Littelfuse, Inc., and all of its affiliate entities.

This balanced protector is a surface mount alternative to the modified TO-220 package. Based on a six-pin surface mount SOIC package, it uses Littelfuse's patented "Y" (US Patent 4,905,119) configuration. It is available in surge current ratings up to 500A.

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 & surge ratings apply to forward and reverse polarities.
Vdrm is measured at Idrm.
Vs is measured at 100 V/µs.
Special voltage (Vs & Vdrm) and holding current (Ih) requirements are available upon request.
Off-state capacitance is measured between Pins 1-3 and 1-4 at 1 MHz with a 2 V bias.
Designed to meet balance requirements of GTS 8700 and GR 974.
