BC808-40LT1

Overview

The BC808-40LT1 is a PNP silicon epitaxial planar transistor manufactured by onsemi in an SOT-23 package. It features a collector-emitter voltage (VCEO) of -25 V, a continuous collector current (IC) of -500 mA, and a total device dissipation of 225 mW on an FR-5 board at 25°C. The minimum DC current gain (hFE) is 250 at IC = -100 mA and VCE = -1 V. Transition frequency (fT) is 100 MHz.

Feature Summary

PNP silicon epitaxial planar construction for general-purpose switching and amplification
Low collector-emitter saturation voltage for efficient operation
High DC current gain suitable for driver applications

Applications

General purpose switching circuits
Audio frequency (AF) driver stages
Complementary pairing with BC818 NPN transistors

Procurement Notes

Verify the specific ordering suffix to confirm package type and shipping configuration. Confirm RoHS compliance status if required for your assembly process. Check the manufacturer's latest documentation for any updates to mechanical dimensions or electrical limits before finalizing design integration.

Selection Notes

Select this component when a PNP small-signal transistor with -25 V collector-emitter voltage and -500 mA continuous current capability is required. Ensure the application operates within the specified junction temperature range of -55°C to +150°C and respects the thermal resistance limits for the chosen PCB substrate.

Part Context

This device belongs to the BC807/BC808 family of PNP silicon transistors designed for general audio frequency applications. It serves as the complementary counterpart to the BC817/BC818 NPN series, enabling push-pull configurations in amplifier and switching designs.

Replacement Considerations

Compatible substitutes include the BC808-40 from other manufacturers such as Infineon or Nexperia, provided they match the SOT-23 pinout and electrical ratings.
