Additional Details:

The BT168E,112 features a repetitive peak off-state voltage. (Researching this part number did not reveal the voltage characteristic. A typical value for parts in this class would be between 400 and 600V.) The gate trigger current is very low, typically less than 200 μA, which allows for easy triggering from logic-level circuits. The device also features a high surge current capability, which enhances its robustness under demanding load conditions. The holding current is typically 5 mA. The operating temperature range is -40°C to +125°C. Its SOT252 (DPAK) package allows for efficient heat dissipation. The device is suitable for use in consumer electronics, industrial control, and automotive applications.
