TIC226A is a bidirectional triode thyristor (triac) which may be triggered from the off-state
to the on-state by either polarity of gate signal with main Terminal 2 at either polarity. […]

A bidirectional triode thyristor, often referred to as a TRIAC (short for TRIode for Alternating Current), is a semiconductor device used in AC power control applications. It is a member of the thyristor family and is designed to control the flow of current in both directions through a load when triggered.

1. Bidirectional Conduction: Unlike some other thyristors (such as SCRs or silicon-controlled rectifiers), a TRIAC can conduct current in both directions when it is triggered. It can switch and control AC power by allowing current to flow in either the positive or negative half-cycles of the alternating current waveform.

2. Three Terminals: TRIACs typically have three terminals: MT1 (Main Terminal 1), MT2 (Main Terminal 2), and G (Gate). MT1 and MT2 are the main terminals through which the load is connected, and the G terminal is used to trigger or control the TRIAC.

3. Triggering: The gate (G) terminal is used to apply a small triggering current to the TRIAC. When the gate current exceeds the gate threshold, the TRIAC turns on and conducts current. The TRIAC turns off automatically when the current through it falls below the holding current level or when the polarity of the applied voltage reverses.
