It is a general-purpose switching and amplification device rated for 45 V collector-emitter breakdown and 500 mA continuous collector current. The 330 mW power dissipation limit and 150°C junction temperature rating suit it for moderate-load applications in industrial control, power management, and signal conditioning circuits where a small surface-mount PNP is needed. ## What the 250 hFE minimum gain means for your drive circuit The DC current gain is specified at 250 minimum when tested at 100 mA collector current with 1 V VCE. This relatively high gain means the base drive current required to saturate the transistor is low — for a 500 mA load, the base current needed is under 2 mA even at the minimum gain. That keeps the upstream driver stage simple and reduces component count in applications like relay drivers, solenoid drivers, and low-side switches. ## Switching speed and saturation voltage With a 200 MHz transition frequency, this transistor can handle moderate-speed switching in DC-DC converters and signal amplification up to several MHz. The VCE saturation voltage is specified at 700 mV maximum at 50 mA base current and 500 mA collector current — a typical figure for a general-purpose PNP in this current range. The 100 nA maximum collector cutoff current (ICBO) keeps leakage negligible in high-impedance circuits. The BC80740E6327 comes in the industry-standard SOT-23-3 surface-mount package (Infineon code PG-SOT23-3-11). The three-pin footprint is common across the BC807/BC817 family and many other small-signal transistors, making it straightforward to swap in during layout or BOM revision. The Bulk shipping form means it arrives in tubes or trays, not tape-and-reel — factor that into your pick-and-place setup if you are ordering for automated assembly. For dual-sourcing resilience, the BC807 series has multiple hFE-grade variants (BC807-16, BC807-25, BC807-40) that share the same SOT-23-3 footprint and electrical ratings, differing only in the gain bin.","metaTitle":"BC80740E6327 PNP Transistor, 45 V, 500 mA, SOT-23-3","metaDescription":"BC80740E6327 PNP transistor from Infineon. 45 V VCEO, 500 mA IC, 250 hFE min at 100 mA, 200 MHz fT.
