The Diotec Semiconductor BCX53-16 is a surface-mount general-purpose PNP transistor housed in an SOT-89 package. It supports a maximum collector current of 1 A and features a collector-emitter breakdown voltage of 80 V, with a collector-base breakdown voltage of 100 V. The device offers a DC current gain (hFE) ranging from 100 to 250 at 150 mA. Power dissipation capabilities vary based on PCB copper pad size, reaching up to 2.0 W with a 2500 mm² pad. The transition frequency is typically 50 MHz, and the junction temperature range spans from -55°C to +150°C.
Verify that the specific ordering suffix matches the required automotive qualification level. Confirm compliance with RoHS, REACH, and Conflict Minerals regulations as stated in the datasheet. Ensure the selected variant aligns with the intended commercial or industrial grade requirements before finalizing procurement.
Select this component when a PNP transistor with high collector current and low saturation voltage is required. Consider the thermal resistance characteristics relative to the available PCB copper area for heat dissipation. Verify that the hFE group meets the circuit's amplification needs and that the operating temperature range fits the environmental conditions.
This part belongs to the BCX53 series of SMD general-purpose PNP transistors manufactured by Diotec Semiconductor. The series includes complementary NPN transistors such as the BCX56. Variants within the family may carry suffixes indicating AEC-Q101 compliance or qualification for automotive standards.
