Product details

PNP small-signal transistor — what the scorch mark tells you

The Infineon BC 856BW H6433 is a 65 V, 100 mA PNP general-purpose transistor in a SOT-323 (SC-70) surface-mount package. It's the kind of part you find in switching and amplifier stages on consumer and industrial boards — signal-level stuff where a PNP is needed for level shifting, current mirror, or low-side drive. The 250 MHz transition frequency tells you it can handle fast edges, and the 250 mW power limit means it's not for heavy lifting. The 15 nA collector cutoff current is tight enough for battery-powered circuits where leakage matters.

Obsolete — the lifecycle reality

This part is officially marked obsolete. The SOT-323 footprint is common, so a pin-compatible PNP with similar ratings is the practical path.

Key ratings for the BOM fit

The 65 V collector-emitter breakdown is the rail-voltage ceiling.

Package and footprint

The SOT-323 (SC-70) package is a three-lead surface-mount. The supplier device package is PG-SOT323.
