The 170 MHz transition frequency supports switching applications up to several megahertz. That means Infineon has flagged it for eventual discontinuation, though it remains available for existing production runs through the independent distribution channel. ## What the headline ratings mean for your circuit The 45 V Vce breakdown gives headroom for 24 V or 36 V rails with derating. The 500 mA Ic maximum covers driving relays, solenoids, small DC motors, or LED strings — but watch the 1 W power dissipation limit: at 500 mA, the Vce drop must stay under 2 V to stay within the package's thermal budget. The 170 MHz fT means it can switch at a few hundred kilohertz without significant gain roll-off, useful for low-frequency PWM or DC-DC converter pre-drive. The 100 nA maximum collector cutoff current (ICBO) is tight enough for battery-powered circuits where leakage matters. ## Package and thermal notes The SC-74 (SOT-457) is a six-lead package with a small footprint — roughly 2.9 mm x 1.6 mm. The supplier device package is PG-SC74-6. For continuous operation near the 500 mA limit, ensure adequate trace width and via stitching to the ground plane.","metaTitle":"Infineon BC817SUE6327HTSA1 NPN Transistor, 45 V, 500 mA","metaDescription":"Infineon BC817SUE6327HTSA1 NPN transistor, 45 V Vce, 500 mA Ic, 170 MHz fT, SC-74 package.
