6.5 Electrical Characteristics⁽¹⁾

Limits apply over the recommended operating junction temperature (T_J) range of -40 °C to +125 °C, unless otherwise stated. Minimum and Maximum limits are specified through test, design or statistical correlation. Typical values represent the most likely parametric norm at T_J = 25 °C, and are provided for reference purposes only. Unless otherwise stated the following conditions apply: V_IN = 12 V.

(1) Min and Max limits are 100% production tested at 25°C. Limits over the operating temperature range are guaranteed through correlation using Statistical Quality Control (SQC) methods. Limits are used to calculate National’s Average Outgoing Quality Level (AOQL).

(2) Typical numbers are at 25°C and represent the most likely parametric norm.
