Complementary NPN/PNP pair in one SC-74
The Infineon BC817UPNE6327HTSA1 packs one NPN and one PNP transistor into a single SC-74 (SOT-457) surface-mount package, saving board space in push-pull drivers, H-bridge pre-drive stages, and level translators where both polarities are needed. Each transistor is rated for a 45 V collector-emitter breakdown and 500 mA continuous collector current. The 170 MHz transition frequency supports switching into the low-MHz range, and the 160 minimum hFE at 100 mA provides predictable gain for saturating switch designs. Maximum power dissipation is 330 mW, which sets the thermal budget for the combined die in the small SC-74 footprint.
Last Buy — secure inventory now
Infineon has announced the final ordering window; after that date the part will no longer be manufactured. Any BOM line using this order code should either secure lifetime buy quantities or begin qualifying a pin-compatible replacement. The official base product number is BC817, which may share the same die in alternate packages or tape configurations — check the BC817 family for ongoing production variants.
Package and marking verification
The package is SC-74, also designated SOT-457, with the Infineon PG-SC74-6 supplier package code. For a Last Buy part like this, date-code and marking consistency matter: the laser etch on the top of the package should match Infineon's factory format for the production week. Any lot with mismatched fonts or smudged marking should be X-rayed or decapped before acceptance.
