The BCP5116H6327XTSA1 is a PNP silicon audio frequency transistor from the BCP51 series, manufactured by Infineon Technologies. It operates within a collector-emitter voltage range of 45 V to 80 V depending on the specific variant and supports a continuous collector current of 1 A. The device features a low collector-emitter saturation voltage and a transition frequency of 125 MHz. It is housed in an SOT-223 package with four pins and is qualified according to AEC-Q101 standards for automotive applications.
Verify the exact voltage rating (BCP51, BCP52, or BCP53) required for your application, as the family shares similar characteristics but differs in breakdown voltages. Confirm the suffix '16' indicates the specific DC current gain binning if precise hFE matching is necessary. Ensure the SOT-223-4 footprint matches your PCB design constraints before finalizing procurement.
Select this component when designing audio amplifier circuits that require robust PNP switching capabilities with high current handling. Consider the complementary NPN types (BCP54...BCP56) if a push-pull configuration is needed. Evaluate the thermal resistance requirements, as total power dissipation is limited to 2 W at a case temperature of 120°C. Ensure the operating junction temperature remains within the specified -65°C to 150°C range.
This part belongs to the BCP51...BCP53 family of PNP silicon AF transistors. It is functionally complementary to the BCP54...BCP56 NPN series. The H6327XTSA1 suffix denotes the specific tape and reel packaging format used by Infineon for automated assembly processes.
Complementary replacement options include the BCP54, BCP55, and BCP56 series for NPN applications. Direct substitutes within the same family depend on the required collector-emitter voltage: BCP51 (45V), BCP52 (60V), or BCP53 (80V). Verify pin compatibility in the SOT-223 package.
