Dual NPN in a compact automotive-grade package
250 MHz transition frequency — fast enough for PWM and switching regulators
With a transition frequency of 250 MHz, the BC846UE6327 comfortably handles switching frequencies up to several tens of megahertz, suitable for gate-drive buffering, DC-DC converter feedback, and high-speed logic translation. The minimum DC current gain of 200 at 2 mA, 5 V ensures consistent drive capability across the active region, which simplifies bias network design.
Package and mounting — TSOT-23-6 with 250 mW power dissipation
Housed in a thin SOT-23-6 package (also designated TSOT-23-6), the BC846UE6327 occupies a minimal footprint on the PCB. The supplier package is PG-SC74-6-1. Total power dissipation is rated at 250 mW — adequate for signal-level operation, but thermal design should account for ambient temperatures up to 150°C junction. Surface-mount assembly is standard; no exposed paddle means the thermal path relies on the leadframe and PCB copper.
