The 2N6027 Programmable Unijunction Transistor is designed to enable the engineer to “program’’ unijunction characteristics such as RBB, η, IV, and IP by merely selecting two resistor values.
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.
The CENTRAL SEMICONDUCTOR 2N2906, 2N2907 series types are silicon 60V 600mA 400mW PNP epitaxial planar transistors designed for small signal, general purpose switching applications.
The D81C55HC-2 is a 2k-bit static RAM (256 bytes) with parallel I/O ports and a timer. It uses silicon gate CMOS technology and consumes a standby current of 100 micro ampere, maximum, while the chip is not selected.
