JAJSGA7B September 2018 – November 2021 TVS1401
PRODUCTION DATA
During large transient swings, the TVS1401 will begin clamping the input signal to protect downstream conditions. While this prevents damage during fault conditions, it can cause leakage when the intended input signal has a fast slew rate. To keep power dissipation low and remove the chance of signal distortion, TI recommends that the designer keep the slew rate of any input signal on the TVS1401 below 2.5 V/µs at room temperature and below 1 V/µs at 85°C as shown in Figure 8-6. Faster slew rates will cause the device to clamp the input signal and draw current through the device for a few microseconds, increasing the rise time of the signal. This will not cause any harm to the system or to the device, however, it can cause device overheating if the fast input voltage swings occur regularly.
