Drive current into base (negative relative to emitter for PNP forward-active operation). VBE(sat) max -1.2V at IC=-800mA, IB=-80mA. |+| 2 | E | passive | Emitter terminal of the PNP BJT. Typically tied to the higher potential (e.g. VCC) in high-side switching or common-emitter configurations. VEBO max -5.0V. |+| 3 | C | passive | Collector terminal of the PNP BJT. VCBO max -40V, VCEO max -25V, IC max -1.5A.
