CYTA4494D BK

Overview

The CYTA4494D BK is a dual, isolated complementary transistor manufactured by Central Semiconductor Corp. It consists of two elements (one NPN and one PNP) housed in an 8-pin SOT-228 surface-mount package. The device features a maximum collector current of 0.3 A and a collector-emitter breakdown voltage of 400 V. Key electrical parameters include a minimum DC current gain (hFE) of 50 and a maximum power dissipation of 2 W. The component operates within a temperature range up to 150 °C and utilizes a plastic/epoxy rectangular small outline form factor.

Feature Summary

Dual, isolated complementary transistors integrated into a single eight-lead SMD case
High voltage and high current capability designed for demanding applications
Utilizes 50% less board space compared to two separate SOT-223 devices

Applications

High voltage switching circuits requiring compact footprint
Complementary amplifier stages in audio or signal processing
Power management systems utilizing surface mount technology

Procurement Notes

Verify the specific suffix 'BK' against the manufacturer's official documentation to confirm packaging details and compliance status. Ensure the ordering part number matches the exact variant required for your design, as suffixes may indicate specific tape-and-reel configurations or regional compliance certifications that do not alter the electrical function.

Selection Notes

Select this component when a dual complementary pair with high voltage ratings is needed in a surface-mount format. The SOT-228 package offers a significant space saving over discrete SOT-223 solutions. Confirm that the 0.3 A current rating and 2 W power dissipation meet the thermal and load requirements of the target application before finalizing the design.

Part Context

This part belongs to Central Semiconductor's line of dual transistors packaged in the new SOT-228 eight-lead SMD case. It is grouped with similar devices such as the CYTA44D, CYT5551D, and CYT5551HCD. These components are designed to provide high performance in a reduced footprint, addressing the need for space-efficient solutions in modern electronics manufacturing.
