C1815 Description

Also known as 2SC1815, the C1815 is a bipolar junction NPN transistor widely used in commercial and educational projects. It is designed for audio frequency amplification and high-frequency oscillator(OSC). The collector-base voltage of the C1815 is 50V, hence it can be easily used in circuits using under 50V DC. The collector current of the C1815 is 150mA, therefore it can drive any load under 150mA. The collector power dissipation and DC current gain of the C1815 are quite good, so it is a perfect choice for audio and electronic signal amplification purposes.

The C1815 transistor has a current gain between 70 and 700. The gain of the C1815O ranges from 70 to 140, C1815Y ranges from 120 to 240, C1815GR ranges from 200 to 400, and C1815BL ranges from 350 to 700.

C1815 Marking

The C1815 is short for 2SC1815. The "2S" prefix isn't always printed on the package, so the 2SC1815 transistor is also labeled "C1815."

  The parameter "DC Current Gain-Min (hFE)" in electronic components refers to the minimum value of the DC current gain of a bipolar junction transistor (BJT). It is a measure of how much the transistor amplifies the input current to produce the output current. The hFE value indicates the ratio of the output current to the input current when the transistor is operating in the active region.

Share this postFrequently Asked Questions

1.What is C1815 transistor?

The C1815 is a bipolar junction NPN transistor widely used in commercial and educational projects. It is used for audio amplification and high-frequency oscillator(OSC). It can be easily used in circuits using below 50V DC because the collector-base voltage of this transistor is 50V.

2.How do you know if a transistor is NPN or PNP?

Connect the positive lead of the multimeter to the Base (B) of the transistor and connect the negative lead to the Emitter (E) of the transistor. If it is an NPN transistor then the meter should show a voltage drop between 0.45V and 0.9V. If it is a PNP transistor, it should display “OL” (Over Limit).

3.How to safely long run C1815 in a circuit?

To get long term performance from this transistor it is recommended to not drive load above 150mA with this transistor, always operate it below the max collector-emitter voltage, always use a suitable base resistor to provide require base current to the transistor, do not store or operate the transistor below -55 centigrade and above +150 centigrade.

4.Is 2N5089 a good replacement for the 2SC1815 in a tube screamer build?

Should work fine. The two transistors are used as emitter followers; in this configuration, most small-signal NPN transistors should work OK if not great. 5089 will be great. Get the pinout right! The pins are in a different order on the 2N5089 from 1815. The 5089 is EBC, 1815 is ECB.

5.What’s the alternative for the Toshiba 2SC1815 used in the Mini Zen?

Sounds like most any of the usual suspects would work. If you're bound to a Japanese transistor pinout, something like a 2SC2240 should work fine, otherwise, you could use a plain ol' BC549B/C or BC550B/C. Pay attention to the fact that the C1815 has a "Japanese" ECB pinout, whereas the BC549 family is CBE. If you are careful and insulate the pins, you can twist them into position.RELATED POSTS
