The DTC123JCA NPN Digital Transistor, manufactured by JSCJ (JCET), is available from Supreme Components International, an authorised distributor of electronic components. This Bias Resistor Transistor (BRT) integrates resistors R1=2.2kΩ and R2=47kΩ, streamlining circuit design by eliminating the need for external biasing resistors. Housed in a compact SOT-23 package, this transistor is ideal for space-constrained applications. With a voltage rating of 50V and a current rating of 100mA, the DTC123JCA is well-suited for switching, inverter, and driver circuits. Its integrated resistors ensure stable operation and reduce component count, leading to simplified assembly and improved reliability. This transistor offers a convenient and efficient solution for digital circuit design.
