2SC1740 Transistor Explained / Description:

2SC1740 or C1740 is an NPN BJT transistor available in TO-92 and TO-92S or E-Line package. TO-92S or E-Line package is a smaller package than TO-92. The transistor is designed for general purpose switching, amplification and radio frequency applications.

The maximum collector current of the transistor is 150mA, maximum collector to emitter voltage is 50V, maximum collector dissipation is 300 milliwatt, minimum and maximum DC current gain is 120 to 560, the max transition frequency is 100MHz to 180MHz, some manufacturers make it with 100MHz transition frequency and some make it with 180MHz transition frequency.

Where We Can Use It & How to Use:

C1740 can be used for wide variety of general purpose applications like switching, amplification and RF applications. When used as a switch it is capable to drive load of upto 150mA and the maximum load voltage can be 50V. It can also be used as a preamplifier and amplifier for various types of electronic signals. Other than that it can also be used for radio frequency applications upto 100MHz or 180MHz.

Applications:

Switching loads upto 150mA

Audio preamplifier applications

Audio amplifier applications

Different types of signal amplification

Darlington pairs

NPN Complementary:

PNP Complementary of 2SC1740 is 2SA933AS.

Replacement and Equivalent:

2SC2412K, 2SC4617, 2SC4081, 2SC5658, 2SC1852, 2SD892A, BC337

Safe Operating Guidelines / Absolute Maximum Ratings:

For safe operating this device do not use it on its max ratings we suggest to always stay 20% below from its absolute maximum ratings. The maximum collector current of the transistor is 150mA therefore do not drive load of more than 120mA, the max collector to emitter voltage is 50V so do not drive load of more than 40V and always store of operate the transistor at temperature above -55 °C and below +150 °C.
