Product details

Pre-biased NPN for switched-load and interface duty

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.

Infineon lists the BCR 135F E6327 as Obsolete.

Frequently asked questions

What is the replacement for BCR 135F E6327?

Infineon has not published a direct official successor for this order code. For a new design, look at current Infineon pre-biased NPN transistors in SOT-723 or SOT-23 packages with R1 = 10 kOhms and R2 = 47 kOhms. The BCR 135 base product number is the family starting point for cross-referencing.
