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).
Note1: Device considered a two-terminal device: Pins 1 and 2 shorted together, and pins 3 and 4 shorted together.
Caution
This device is sensitive to electrostatic discharge. When using this device, please ensure that all tools and equipment are earthed.
