Replacement & Repair Applications
The 2SC6144 can be used as a replacement component when repairing equipment originally fitted with the same transistor. Because power transistor substitutions depend on multiple electrical and thermal parameters, another NPN transistor should not be considered a direct replacement solely because its voltage and current ratings appear similar.
