2SC5250, 2SC3896, 2SC3894

The transistor is primarily developed for use in TV and monitor deflection circuitry, but its excellent specifications also make it suitable for use in a wide range of high voltage and high-speed switching applications, as well as a wide range of general-purpose applications. This transistor can be utilized for audio amplification in addition to switching applications.

Toshiba is a household name in Japan and has long been viewed as a symbol of the country's technological prowess. Its reputation has since been affected following an accounting scandal in 2015 and the bankruptcy of subsidiary energy company Westinghouse in 2017, after which it was forced to shed several underperforming businesses, essentially eliminating the company's century-long presence in consumer markets.
