The BC858B,215 is a PNP general-purpose transistor manufactured by Nexperia in the SOT23 (TO-236AB) surface-mounted package. It features a collector-emitter voltage of -30 V and a continuous collector current of -100 mA. The device provides a DC current gain range of 220 to 475 at a collector current of -2 mA and -5 V. Key electrical characteristics include a collector-base breakdown voltage of -30 V and an emitter-base breakdown voltage of -5 V.
Verify the specific ordering suffix matches the required packaging format. Confirm that the component version aligns with non-automotive qualification requirements as specified in the product data sheet revision history. Ensure design compliance with absolute maximum ratings for thermal and electrical stress conditions.
Select this component when a low-voltage PNP transistor with moderate current handling is required. The BC858B variant offers a specific gain band suitable for consistent amplification performance. Consider the SOT23 footprint for space-constrained printed circuit board layouts requiring standard surface-mount assembly techniques.
This part belongs to the BC856/BC857/BC858 family of PNP general-purpose transistors. The BC858B designation specifically indicates the lower voltage rating compared to the BC856 series variants within the same package type. It serves as a complementary device to the BC848B NPN transistor.
