ELECTRICAL CHARACTERISTICS
Unless otherwise specified, these specifications apply over the operating ambient temperature of 0°C to +70
°C

+ 0.5V, and are for DC characteristics only. (Low duty cycle pulse testing techniques are used
which maintains junction and case temperatures equal to the ambient temperature.)
