This is more of a concern for Darlingtons, Sziklai pairs and similar DC coupled transistors where the junction temperature is very high and the gain is very high. Is in the SPICE model will give you a guess for Icbo. | |

| Apr 5, 2019 at 19:42 | comment | added | Kutsit | Got it but still can you please tell me the magnitude at room temperature ? Because I want to have a idea of the magnitude. | |
| Apr 5, 2019 at 19:42 | comment | added | G36 | But do we really care about \$I_{CBO}\$ when we are using BJT's in modern applications? | |
