The TISP61089ADR-S is a dual-p gate SCR manufactured by Bourns. It is designed for high performance power switching applications with a fast forward switching current of 4A. This SCR is encapsulated in a small SMD package for improved thermal dissipation. It also features low on-state voltage, low trigger current, and low gate threshold. The SCR also has an extended working temperature range (-40 °C to 125 °C). This makes it suitable for use in harsh industrial environments.
