Dual NPN/PNP in one SC-74 package
The BC846UPNE6327HTSA1 packs a complementary NPN and PNP transistor into a single SC-74 (SOT-457) surface-mount package, saving board space in push-pull drivers, current mirrors, and signal-level translation circuits where you need both polarities matched in thermal proximity.
Last Buy — plan the BOM migration
Infineon has marked this part Last Buy. That means the manufacturer will accept final orders within a defined window, after which the part is discontinued. For existing designs, secure your lifetime buy quantity now; for new designs, evaluate a pin-compatible dual transistor in the same SC-74 footprint. We source the BC846UPNE6327HTSA1 through independent distribution channels.
Package and thermal note
The SC-74 (SOT-457) package is a 6-lead small-outline with a 1.5 mm body width. The supplier device package is PG-SC74-6. Maximum power dissipation is 250 mW total for both transistors, with the junction temperature limit at 150 °C. In a typical 85 °C ambient, derate to about 160 mW total — the copper pad area under the package sets the effective thermal resistance.
