=== Turn-on, turn-off, and storage delay ===
{{Main|Baker clamp}}

Bipolar transistors, and particularly power transistors, have long base-storage times when they are driven into saturation; the base storage limits turn-off time in switching applications. A [[Baker clamp]] can prevent the transistor from heavily saturating, which reduces the amount of charge stored in the base and thus improves switching time.<!-- at a cost of increased V<sub>CE,sat</sub> -->
