_ 0182998 ACRIAN INC GENERAL DESCRIPTION The TAN250A is a high power common base bipolar transistor. It is designed for pulsed TACAN systems and has 20sec pulse widths and 5% duty factors. The device has gold thin-film metallization and diffused ballasting for proven highest MTTF. Surface passivation eliminates contamination and extends life. Low thermal resistance, hermetically sealed packaging reduces junction temperature, extends life and meets full military requirements.
