Pre-biased NPN for space-constrained loads
The BCR 139T E6327: The Infineon BCR 139T is an NPN pre-biased transistor in an SC-75 (SOT-416) surface-mount package, integrating a 22 kOhm base resistor (R1) on-chip. This eliminates one external component per channel, saving board area in high-density designs.
Key ratings at a glance
DC current gain (hFE) minimum is 120 at 5 mA, 5 V. Transition frequency is 150 MHz.
Lifecycle and sourcing posture
The base product number BCR 139 covers multiple R1 value variants; verify the resistor code against your design.
