Electrical Characteristics (Unless otherwise specified, these specifications apply over the operating ambient temperatures for SG1524 with -55°C ≤ T ≤ 125°C, SG2524 with A -25°C ≤ T ≤ 85°C, SG3524 with 0°C ≤ T ≤ 70°C, and +V = 20V. Low duty cycle pulse testing techniques are used which maintains junction and A A IN case temperatures equal to the ambient temperature.)
