What this dual NPN pre-biased transistor is
The Infineon BCR119SE6327BTSA1 is a dual NPN pre-biased transistor array in a 6-pin SOT-363 package. Each transistor integrates bias resistors (R1 = 4.7 kΩ) so the base drive network is already on-chip — one less passive per channel on the bill. Collector current is rated 100 mA maximum, with a VCEO breakdown of 50 V and a transition frequency of 150 MHz.
Obsolete — what that means for sourcing
No official successor order code appears on the record.
The 100 mA collector current and 50 V VCEO ceiling suit low-power switching and interface circuits. The 150 MHz transition frequency is adequate for switching up to a few megahertz. Maximum power dissipation is 250 mW.
