TIP142 Equivalent

This is a replacement table for the tip142 equivalent. They both amplify circuits or act as switches.

Picture	Name	Makers	Maximum Power	Maximum Current	Maximum Voltage	Package Type
	TIP142	ON Semiconductor	80W	10A	100V	TO-220
	TIP32C	ON Semiconductor	40W	3A	100V	TO-220
	S8550	Sanken	15W	1.5A	50V	TO-92
	BD139	STMicroelectronics	12W	1.5A	80V	TO-3
	2N5401	ON Semiconductor	80W	10A	150V	TO-220
	MJE2955T	ON Semiconductor	115W	15A	60V	TO-220

Note:

In this table, 2N5041 is the most suitable substitute, and its parameters are fully compatible with TIP142. When using MJE2955T as a replacement, it should be noted that the voltage should not exceed the maximum voltage of MJE2955T, 60 V. When using S8550, BD139 as a replacement, it is necessary to see whether the voltage, current and power in the actual circuit are greater than the maximum parameter, and when replacing it with TIP32C, it is not possible to look at the parameter only, because TIP32 is a PNP transistor, and the polarity is different from that of TIP142, so it is necessary to modify the circuit before replacing it.
