Abstract: Thyristor latching current and maintaining current have important effects on its working state. With thyristor conduction characteristics latching current is derived from carrier density; Based on current gain of NPN transistor, maintaining current is obtained. Compared with simulation results of Sentaurus TCAD software, calculated results have good agreement. It shows correctness of the formula.

Key words: thyristor, latching current, maintain current, current gain
