| IGBT | BJT |
|---|---|
| IGBT is a voltage controlled device. | BJT is a current controlled device. |
| The input impedance of IGBT is high. | The input impedance of BJT is low. |
| The drive circuit of IGBT is simple. | The drive circuit of IGBT is complex. |
| Switching speed of IGBT is more than BJT. | Switching speed of BJT is in the range of microseconds means slow switching speed. |
| IGBT shows negative temperature coefficient up to 70% after that is shows positive temperature coefficient. | BJT is the negative temperature coefficient device. |
| Conduction losses are low. | Conduction losses are low. |
| Switching losses are low for high frequency. | Switching losses are high for high frequency. |
| IGBT is a bipolar device. | BJT is a bipolar device. |
