Overview
The BD136-16STU is a PNP silicon epitaxial planar transistor manufactured by STMicroelectronics, housed in the SOT-32 plastic package. It features a maximum collector-emitter breakdown voltage of 45V and a continuous collector current rating of 1.5A. The device exhibits a DC current gain (hFE) of 100 when tested at an emitter current of 150mA and a collector-emitter voltage of 2V. This component is designed for use in audio amplifiers and drivers utilizing complementary or quasi-complementary circuits.
Feature Summary
- Epitaxial planar construction mounted in a compact SOT-32 plastic package
- Designed specifically for audio amplifier and driver applications
- Suitable for complementary or quasi-complementary circuit topologies
Applications
- Audio amplifiers
- Driver circuits
- Complementary circuit designs
- Quasi-complementary circuit designs
Procurement Notes
Verify that the manufacturer designation on the component matches STMicroelectronics, as this part number is produced by ST rather than Fairchild Semiconductor. Confirm the specific suffix '16' to ensure the correct hFE pre-selection grade is received. Check the package marking for the SOT-32 identifier to distinguish it from other variants in the series.
Selection Notes
Select this component when a PNP transistor with a 45V collector-emitter voltage rating and 1.5A current capacity is required. Ensure the application utilizes complementary or quasi-complementary configurations where this device pairs with NPN types such as the BD135 or BD139. Verify that the SOT-32 package dimensions fit the target PCB layout constraints.
Part Context
The BD136-16 belongs to a family of power bipolar transistors rated below 500V. It serves as the complementary PNP counterpart to the BD139 NPN transistor. The series is characterized by pre-selected DC current gain options to facilitate matched performance in push-pull amplifier stages.
Replacement Considerations
The BD136-16 can be replaced by other BD136 variants with matching electrical ratings if the specific hFE binning is not critical. For direct functional substitution in complementary circuits, the BD139 NPN transistor serves as the paired component.
