Do not expose it in temperature above +150 centigrade and below -55 centigrade and always use a suitable base resistor. For best performance we suggest to not touch the max load limit always stay under it. To run this transistor safely in a circuit it is suggested to not operate it voltage over 50V, always connect the pins correctly and do not provide it load above 150mA because the max load this transistor can handle is 150mA. So just look for a substitute that has H FE of at least 100 at an I C of around 10mA, and you should be OK. In your circuit higher gain is better, but 100 is plenty enough. It can also be used in RF circuits under 200MHz frequency. Any substitute that is within or close to that range should be fine (assuming the circuit was designed to accommodate such a wide variation). online, order, part, replacement, replacement part, substitute, sale, shopping. The saturation voltage of most BJT transistors are 0.6V but the C945 has only 0.3V therefore it can perform well in low voltage circuits or in any circuit where low base voltage is available and other BJT transistors are not saturating. Semiconductor: 2SC1815 (2SC 1815) - TRANSISTOR SILICON NPN / 60V / 0.15A. Moreover the transistor is also low noise device, and has a good DC current gain that is 70 to 700.Īs discussed above the transistor has a good DC current gain and low noise type due to which it is ideal to use in audio preamplifier & audio amplifier circuits stages or amplification of other signals in electronic circuits. The saturation voltage of the transistor is only 0.3V which is also a good feature of this transistor. It is manufactured in TO-93 package, the max load this transistor can drive is around 150mA or 0.15A that is enough to operate many devices in a circuit for example LEDs, Relays, ICs, transistors and other parts of a circuit. Max Storage & Operating temperature Should Be: -55 to +150 CentigradeĢN2222, 2N3904, 2SC1815, 2SC3198 (Pin configuration of SOME transistors are different from C945, check pin configuration before replacing in a circuit)Ĭ945 is a general purpose NPN transistor used in wide variety of commercial and educational electronic circuits.Minimum & Maximum DC Current Gain (h FE): 70 – 700 Substitute equivalent to transistor A1015 - A1015 Datasheet Search cross-reference (PDF) 0.1.Max Collector Dissipation (Pc): 400 miliWatt.Note that the lead connections of substitute transistors may vary from those shown in Figure One. striker applauded by away fans after appearing as a substitute. A 2N3819 will work equally well as the MPF102 in the detector and a 2N3904 or 2N2222 can be substituted for the BC548 in the audio amplifier. top brands sell cheap 3000PCS C1815 2SC1815 HF SOT-23 SMD transistor cheap sale outlet. Max Collector-Emitter Voltage (V CE): 50V Obtaining these should pose no difficulty.Advertisements Features / technical specifications:
