The recommended operating temperature range for the TLP521-4XGB is -40°C to 100°C.
To ensure reliability in high-temperature applications, it is recommended to derate the device's current and voltage ratings according to the datasheet's thermal derating curve.
The maximum allowable voltage for the TLP521-4XGB is 80V, but it is recommended to operate the device at a voltage below 60V for optimal performance and reliability.
The correct resistor value can be calculated using the formula R = (Vcc - Vf) / If, where Vcc is the supply voltage, Vf is the forward voltage of the LED, and If is the desired LED current.
The typical propagation delay time for the TLP521-4XGB is around 10-20 μs, but this can vary depending on the specific application and operating conditions.
