See Dissipation Rating Table
Voltage values are with respect to network GND, unless otherwise specified.
This is the voltage between two emitters of a multiple-emitter transistor.
This value applies when the base-emitter resistance (RBE) is equal to or less than 500
Ω.
Both halves of these dual circuits may conduct rated current simultaneously; however, power dissipation averaged over a short time
interval must fall within the continuous dissipation rating.
