It provides excellent switching speeds, reliable signal amplification, and robust medium-power handling for a massive variety of everyday circuit applications.NameTypesImagePriceAdd Link2SA733PNP350Add to Basket2SC1623NPN400Add to Basket2SC945NPN350Add to BasketA1015PNP350Add to BasketBC807PNP400Add to BasketBC817NPN300Add to BasketC1815NPN400Add to BasketMMBT2222ANPN350Add to BasketMMBT2907PNP400Add to BasketMMBT3904NPN350Add to BasketMMBT3906PNP350Add to BasketMMBT4403PNP400Add to BasketMMBT5401PNP350Add to BasketMMBT5551NPN350Add to BasketMMBTA42NPN400Add to BasketMMBTA44NPN350Add to BasketMMBTA92PNP350Add to BasketS8050NPN350Add to BasketS8550PNP350Add to BasketS9012PNP350Add to BasketS9013NPN350Add to BasketS9014NPN350Add to BasketS9015PNP350Add to BasketS9018NPN350Add to BasketSI2305P-Channel400Add to BasketMedium-Power High-Side SwitchDesigned for fast, efficient logic-level control, the BC807-25 PNP Transistor comfortably handles continuous collector currents up to -500mA. This makes it the perfect choice for high-side switching. Use it to cleanly route positive power to heavier 5V sensors, drive indicator LEDs, or act as a reliable interface between your microcontroller and larger mechanical relay driver circuits.Compact SOT-23 FootprintModern electronics demand smaller footprints without sacrificing current capacity. The SOT-23 surface-mount package allows you to integrate this versatile transistor into space-constrained IoT devices, wearables, and custom logic boards. Featuring the industry-standard top mark 5B, this component is easy to identify during manual prototyping, inventory management, or automated pick-and-place assembly.Optimal Gain RangeBipolar junction transistors are categorized by their DC current gain (hFE). The “-25” suffix on the BC807-25 PNP Transistor indicates a highly desirable, mid-range gain classification of 160 to 400. This ensures predictable, efficient performance whether you are saturating it fully as a switch or biasing it as a linear amplifier.Key FeaturesHigh Current Capability: Drives continuous loads up to -500mA, ideal for medium-power switching applications where small-signal transistors fail.Predictable Amplification: The “-25” classification ensures a reliable DC current gain (hFE) between 160 and 400.Miniature Footprint: The SOT-23 SMD package optimizes valuable PCB real estate while maintaining great thermal stability.Technical SpecificationsTransistor Polarity: PNP BJTCollector-Emitter Voltage (VCEO): -45V MaximumCollector-Base Voltage (VCBO): -50V MaximumEmitter-Base Voltage (VEBO): -5V MaximumContinuous Collector Current (IC): -500mAPeak Collector Current (ICM): -1.0APower Dissipation (PD): 250mWDC Current Gain (hFE): 160 to 400 (at IC = -100mA)Package Type: SOT-23 (Surface Mount)Common Top Marking Code: 5BIdeal ApplicationsHigh-Side Load Switching: Turning on power to LED strips, small DC motors, relays, and medium-power modules from the positive rail.Signal Amplification: Serving as a reliable driver stage in audio amplifiers and analog sensor circuits.Push-Pull Amplifiers: Pairing with its NPN complement (BC817) for efficient audio and motor drive circuits.Electronics Repair: Replacing faulty 5B-marked PNP transistors in commercial logic boards, toys, and small appliances.
