It integrates a 10 kOhm base resistor (R1) and a 47 kOhm base-emitter resistor (R2), so the external bias network is already on-die. This part is designed for low-current switched-load applications where you want to reduce board area and component count — think relay drivers, LED indicators, or logic-level interface buffers. ## Key ratings — what they mean for a replacement search Collector-emitter breakdown is rated at 50 V, and continuous collector current maxes out at 100 mA. The 250 mW power dissipation limit in SOT-723 means this is a signal-level switch, not a power device. DC current gain minimum is 70 at 5 mA collector current, and the transition frequency of 150 MHz is fine for low-speed switching up to a few megahertz. ## Obsolete — sourcing reality Infineon lists the BCR 135F E6327 as Obsolete.","metaTitle":"BCR 135F E6327 NPN Pre-Biased Transistor, 50 V, 100 mA","metaDescription":"Infineon BCR 135F E6327 NPN pre-biased transistor, 50 V, 100 mA, 250 mW, SOT-723.
