The BC856B/DG/B3,215 is a PNP general-purpose transistor manufactured by Nexperia USA Inc. It utilizes the SOT-416 (SC-74) surface-mount package with three pins. Key electrical parameters include a maximum collector-emitter voltage (VCEO) of -65 V and a collector-base voltage (VCBO) of -80 V. The device supports a maximum continuous DC collector current (IC) of -100 mA and a power dissipation (Pd) of 150 mW. It features a minimum DC current gain (hFE) of 125 at specified test conditions. The transition frequency (fT) is rated at 100 MHz. Operating temperatures range from -65°C to +150°C junction temperature.
Verify the specific suffix 'DG' against official Nexperia documentation to confirm pinout and electrical tolerances, as standard BC856B variants may differ. Ensure the ordering code matches the required gain bin and packaging format. Cross-reference the datasheet revision date to confirm parameter validity. Confirm RoHS compliance status for your region's regulatory requirements before finalizing procurement.
Select this component when a PNP transistor with -65 V breakdown and 100 mA current capacity is required in an SOT-416 footprint. Consider the hFE minimum of 125 for biasing stability. Compare against the NPN complement BC846B if complementary pairs are needed. Verify thermal management needs given the 150 mW power dissipation limit in small packages.
This part belongs to the BC856 series of PNP general-purpose transistors from Nexperia. It is designed as a complement to the BC846 NPN series. The SOT-416 package offers space-saving advantages for dense PCB layouts. The series is widely used in portable devices and industrial applications due to its balance of performance and size.
Official pin-to-pin replacements include BC856BT and BC856BW variants from Nexperia, provided the package and electrical ratings match. Other manufacturers' equivalents must be verified for identical pinout and VCEO/IC specifications.
