ZTX651 Equivalent

This meter is a replacement for the ZTX651 model. It is mainly used for motor drive and circuit amplification.

Picture	Name	Makers	Maximum Power	Maximum Current	Maximum Voltage	Package Type
	ZTX651	Diodes Incorporated	1W	2A	60V	TO-92
	MMBT5551	On Semiconductor	225mW	600mA	160V	SOT-23
	2N3904	On Semiconductor	300mW	600mA	150V	SOT-23
	BD139	NXP Semiconductors	1.5W	1.5A	80V	TO-126
	S8050	JCET	500mW	0.5A	45V	TO-92
	TIP41C	Texas Instruments	4W	6A	100V	TO-220

Note:

The TIP41C and BD139 in the table are very suitable replacements with very similar parameters to the ZTX651. When using the S8050 as a replacement, attention should be paid to the voltage, current and power in the actual circuit. The voltage, current, and power in the circuit should not exceed 45V, 0.5A, and 0.5W, respectively, and care should be taken to ensure that the parameters match when using the other types in the table as replacements.
