Common Transistors
- Bipolar transistors
- 2N3055: old fashioned, high power switching transistor. These days it almost never makes sense to use a 2N3055 when a MOSFET or IGBT could be used instead.
Bipolar junction: 2N2222, 2N3904, and 2N3906
MOSFET: BS170 and 2N7000
The BS170 is nearly identical to the 2N7000, but handles over twice the power.
- max voltage
- 60 V
- max current
- 200 mA (2N7000) or 500 mA (BS170)
- max power
- 400 mW (2N7000) or 883 mW (BS170)
- on resistance
- 5 Ω at 10 V Vgs
MOSFET IRF510
This is a very popular high power MOSET.
- max voltage
- 100 V
- max current at 100 ℃
- 4 A
- on resistance
- 0.54 Ω at 10 V Vgs
IGBTs: 25N120, 30N120
Diodes
1N4148 and 1N4001
