The S0802NH is a silicon-controlled rectifier (SCR) from STMicroelectronics, designed for applications requiring direct control of AC power. It is encapsulated in the TO-92 package, which is well-suited for through-hole mounting on printed circuit boards. This SCR is capable of withstanding voltages up to 800V, making it an excellent choice for high-voltage applications.

Key Features

• Peak Repetitive Off-State Voltage (V_DRM): 800V
• Average On-State Current (I_T(AV)): 2A
• Gate Trigger Current (I_GT): Maximum of 200 µA
• Non-Repetitive Surge Current (I_TSM): Provides high surge capability
• Low Gate Trigger Voltage (V_GT): Ensures easy triggering
• High Holding Current (I_H): Prevents unwanted triggering from noise and voltage fluctuation
• TO-92 Package: Compact and suitable for through-hole PCB design

Applications

The S0802NH SCR is versatile and can be used in a variety of applications. Its high blocking voltage and current handling capability make it ideal for:

• Power switching circuits
• Phase control in light dimmers and motor speed controllers
• Over-voltage crowbar protection circuits
• Control systems requiring high voltage/current handling
