P1602ABL

The Littelfuse P1602ABL is a two-chip SIDACtor® thyristor housed in a modified TO-220 package, engineered to safeguard baseband equipment from damaging overvoltage transients. This device offers a peak surge current capability that aids in complying with various global regulatory standards for voice and DS-1 equipment.

Key electrical characteristics include a minimum standoff voltage (VDRM) of 65V and a maximum of 95V at 5µA, with a breakdown voltage (VS) ranging from 130V to 190V at 100V/µs. The on-state voltage (VT) is a maximum of 4V at 2.2A. The device also features a minimum holding current (IH) of 150mA and a maximum latch current (IS) of 800mA. Capacitance values are specified at 45pF to 145pF between pins 1-2 and 3-2, and 25pF to 85pF between pins 1-3, measured at 1MHz with a 2V bias.

Designed for through-hole mounting, the P1602ABL offers low voltage overshoot and low on-state voltage. It is built to fail short-circuit when surged beyond its ratings, providing a fail-safe mechanism. The component is RoHS compliant and Pb-free, with a terminal finish of tin (Sn).

This SIDACtor® series is applicable to global standards including TIA-968-A, TIA-968-B, ITU K.20/21, GR 1089, and IEC 61000-4-5. Its robust design ensures that surge capability does not degrade after multiple surge events within specified limits.
