Overview
The BC808-25LT1 is a general-purpose PNP silicon epitaxial planar transistor manufactured by onsemi. It is designed for switching, audio frequency (AF) driver, and amplifier applications. The device features a collector-emitter voltage rating of -25 V and a continuous collector current of -500 mA dc. Electrical characteristics include a minimum DC current gain (hFE) of 160 at -100 mA and a transition frequency (fT) of 100 MHz. It is housed in a surface-mount SOT-23 package (CASE 318).
Feature Summary
- PNP silicon epitaxial planar construction optimized for switching and amplification.
- Low collector-emitter saturation voltage for efficient power handling.
- Complementary to the BC817 NPN transistor series.
Applications
- General purpose switching circuits.
- Audio frequency (AF) driver stages.
- Amplifier applications.
Procurement Notes
Verify the specific ordering suffix 'LT1' against the manufacturer's official documentation to confirm tape and reel packaging specifications. Ensure the component meets RoHS compliance requirements if applicable to the design. Cross-reference the marking code '5F' with the datasheet to validate authenticity and manufacturing origin.
Selection Notes
Select this component when a PNP transistor with a -25 V collector-emitter voltage rating is required. Consider the -500 mA continuous current limit and the SOT-23 thermal dissipation characteristics. Verify that the hFE range of 160 to 400 fits the circuit biasing requirements compared to higher gain variants like the BC808-40.
Part Context
This part belongs to the BC808 family of general-purpose PNP transistors from onsemi. It serves as the complementary counterpart to the BC817 NPN transistor. The family includes variants differentiated by breakdown voltage ratings, such as the BC808-25 and BC808-40, allowing designers to choose based on specific voltage headroom needs.
Replacement Considerations
Compatible substitutes include the BC808-40LT1 for higher voltage tolerance or the BC808-25LT1G for lead-free packaging variations. Other manufacturers producing equivalent SOT-23 PNP transistors with matching electrical parameters may also be suitable.
