BCY59X Description

Short technical summary and product information.

The BCY59X is a high-performance NPN bipolar junction transistor housed in a TO-18 metal can package. It is designed for general-purpose switching and amplification applications. Key electrical characteristics include a maximum collector-emitter voltage of 45V, a continuous collector current of 200mA, and a power dissipation of 390mW. The transistor offers a minimum DC current gain (hFE) of 180 at 2mA collector current and 5V collector-emitter voltage. With a typical transition frequency of 200MHz, it is suitable for low to medium frequency amplification. The saturation voltage is 700mV at a base current of 2.5mA and collector current of 100mA. The device is through-hole mounted and operates over a junction temperature range up to 175°C. The TO-18 metal can package provides robust mechanical protection and good thermal performance.
