The recommended operating temperature range for the RS403L is -55°C to 150°C.
To ensure reliability, it's recommended to derate the power dissipation of the RS403L according to the ambient temperature, and to use a heat sink if necessary.
The maximum allowable voltage for the RS403L is 400V, but it's recommended to operate within the specified voltage range to ensure reliability.
To prevent ESD damage, it's recommended to handle the RS403L with an anti-static wrist strap or mat, and to use ESD-protected packaging and storage.
Yes, the RS403L can be used in switching power supply applications, but it's recommended to ensure that the device is operated within its specified voltage and current ratings.
