The DC5V 2 Channels Relay Module is similar to the 4-channel version but with two relay channels. It is suitable for projects requiring the control of two separate high-power devices, providing a reliable interface between microcontrollers.
The MJH6287G, MJH-6287, 6287 is a 100V 20A 4MHz 160W–PNP - Darlington Bipolar Transistor Through Hole TO-218 from ON Semiconductor. MJH6284 (NPN), MJH6287 (PNP) Darlington Complementary Silicon Power Transistors.
The MJE350 is a silicon planar PNP transistor intended for use in medium power linear and switching applications. It is mounted in TO-126. The complementary NPN type is MJE340.
The MJH6284G, MJH6284, 6284 is a – 100V 20A 4MHz 160W NPN - Darlington Bipolar Transistor Through Hole TO-218 from ON Semiconductor. MJH6284(NPN), MJH6287(PNP) Darlington Complementary Silicon Power Transistors.
This device is designed as a general−purpose amplifier and switch. The useful dynamic range extends to 60V 200mA 625mW as a switch and to 100MHz as an amplifier.
