BRY39T Datasheet | Philips Semiconductors

_______________Jl__B_RY_39T__ THYRISTOR TETRODE The BRY39T is a planar p-n-p-n trigger device in a TO-72 metal envelope, intended for use in low-power switching applications such as relay and lamp drivers, sensing network for temperature and as a trigger device for thyristors and triacs. For BRY39P and BRY39S see 'Small signal transistors' handbook.
