CYTA44D BK

Overview

The CYTA44D is a surface mount dual, isolated high voltage NPN silicon transistor manufactured by Central Semiconductor Corp. Encased in an epoxy molded SOT-228 package, the device utilizes an epitaxial planar process for robust performance. It features two independent transistors with a maximum collector-emitter voltage of 400 V and a continuous collector current rating of 300 mA per element. The unit supports a power dissipation of 2.0 W at 25°C ambient temperature and operates within a junction temperature range of -65 to +150 °C.

Feature Summary

Dual configuration containing two electrically isolated NPN transistors within a single package
High voltage capability suitable for demanding circuit applications
Surface mount construction utilizing an epoxy molded SOT-228 case

Applications

High voltage switching circuits
Isolated signal processing stages
Power management systems requiring dual NPN elements

Procurement Notes

Verify the specific ordering suffix required for your application before purchase. The manufacturer offers distinct plating options that must be explicitly requested during the ordering process. Confirm whether lead-free or tin/lead plating is necessary for your assembly requirements to ensure compliance with project specifications.

Selection Notes

Select this component when a dual NPN configuration with high voltage isolation is required in a surface mount format. Ensure the design accommodates the 2.0 W power dissipation limit and the thermal resistance characteristics of the SOT-228 package. Verify that the 400 V collector-emitter voltage meets the peak operating demands of the target circuit.
