Pre-biased NPN for compact switching
The BCR 116F E6327: NPN pre-biased digital transistor in a SOT-723 surface-mount package. It integrates two bias resistors — a 4.7 kΩ base resistor (R1) and a 47 kΩ base-emitter resistor (R2) — so you can drive it directly from a logic output without external resistors. This saves board space and reduces component count in high-density designs like I/O modules, relay drivers, and signal-level switches.
Key ratings at a glance
Collector-emitter breakdown voltage is 50 V, with a maximum continuous collector current of 100 mA. Power dissipation is capped at 250 mW. DC current gain (hFE) is a minimum of 70 at 5 mA collector current and 5 V VCE. Saturation voltage is 300 mV maximum at 500 µA base current and 10 mA collector current. Transition frequency is 150 MHz, adequate for low-speed switching up to a few megahertz.
Package and storage note
Housed in a SOT-723 package (supplier device code PG-TSFP-3), this is a three-lead surface-mount device. Store the reels dry — MSL level is typical for this package class, so keep the moisture barrier bag sealed until reflow.
