SC-7 -UB. ±. Note: Using continuously under heavy loads (e.g. the application of high temperature/current/voltage and the significant change in temperature, etc.) may cause this product to decrease in the reliability significantly even if the operating conditions (i.e. operating temperature/current/voltage, etc.) are within the absolute maximum ratings. Please design the appropriate reliability upon reviewing the Toshiba Semiconductor Reliability Handbook ( Handling Precautions / Derating Concept and Methods ) and individual reliability data (i.e. reliability test report and estimated failure rate, etc). Thermal Characteristics Characteristics Symbol Max Unit Thermal resistance, channel to case R th (ch-c).7 C/W Thermal resistance, channel to ambient R th (ch-a). C/W Note : Ensure that the channel temperature does not exceed. Note : V DD = 9 V, T ch = C (initial), L =. mh, R G = Ω, I AR = A Note : Repetitive rating: pulse width limited by maximum channel temperature This transistor is an electrostatic-sensitive device.
