Overview
The CMLT3474 BK is a dual, low VCE(SAT) silicon transistor in an SOT-563 surface mount package. It integrates one NPN and one PNP transistor designed for small signal general purpose amplifier and switching applications requiring low collector-emitter saturation voltage. Maximum ratings include a collector-base voltage of 40V, collector-emitter voltage of 25V, emitter-base voltage of 6.0V, continuous collector current of 1.0A, peak collector current of 1.5A, and power dissipation of 350mW at 25°C ambient temperature.
Feature Summary
- Dual configuration integrating complementary NPN and PNP transistors within a single compact surface mount package.
Applications
- Small signal general purpose amplifier circuits
- Low voltage switching applications
Procurement Notes
This component has been officially transitioned to End of Life (EOL) status by Central Semiconductor Corp. The effective date for placing last purchase orders is six months from the notice date, with final shipments occurring twelve months after the notice. Minimum order quantities may apply during this period. No direct replacement part numbers are currently available from the manufacturer.
Selection Notes
Select this device when a compact solution for complementary NPN/PNP switching or amplification is required. Verify that the 25V collector-emitter voltage and 350mW power dissipation limits meet the circuit requirements. Note that the specific suffix indicates the plating type, which must be confirmed against environmental compliance needs.
Part Context
The CMLT3474 belongs to a family of dual low VCE(SAT) transistors manufactured by Central Semiconductor Corp. Other variants in this series include the CMLT3410 (dual NPN) and CMLT7410 (dual PNP). All devices share the same SOT-563 package outline and similar electrical characteristics tailored for low saturation voltage performance.
Replacement Considerations
No replacement part numbers are listed by the manufacturer for this discontinued item. Designers should consult the manufacturer's support team via their online inquiry portal to locate potential alternate sources or suitable substitutes.
