The ROHM Semiconductor DTB123YK is a digital transistor designed for applications requiring simplified circuit configurations, such as inverters, interfaces, and drivers. It features built-in bias resistors, eliminating the need for external input resistors and facilitating easier device design. This transistor supports a supply voltage (VCC) of up to -50V and a collector current (IC) of -500mA.
The DTB123YK is housed in a SOT-346 (SMT3) surface-mount package. Its inner circuit includes integrated resistors, R1 typically 2.2kΩ and R2 typically 10kΩ, which are thin-film resistors offering complete isolation. This design minimizes parasitic effects and simplifies operation, requiring only the setting of on/off conditions.
Key electrical characteristics include an input voltage range of -12V to 5V, a maximum power dissipation of 200mW, and a junction temperature up to 150℃. The device offers a typical DC current gain (hFE) of 56 and a transition frequency (fT) of 200MHz, making it suitable for various digital switching applications.
