However, it may break down destructively, or may break down safely (zener diodes break down safely). Be careful about reading the specification for PNP transistors, make sure you have the voltage polarity correct (a schematic in your question would be a great benefit). Make sure you are reading between the correct terminals. You can safely apply a forward current to a BE junction which will then limit it to 0.7ish volts, and a reverse voltage of maybe 5 V without worries for 'most' transistors. | |

| May 22, 2022 at 9:48 | comment | added | Finbarr | I suspect that if you look at the data sheet again you'll see that V_EBO is a negative value.. It's the breakdown voltage when the junction is reverse biased. | |
