Other Parts Discussed in Thread: STRIKE, TPD1E04U04
Hi,
I am looking for TVS diode for pushbutton connected to MCU GPIO and UART pins connected to non inverting buffer against ESD(+/- 4 KV contact,+/-8 KV air discharge),EFT protection (+/-1KV).
End application having typical operating voltage 3.3 V, MCU GPIO absolute max voltage 3.6 V and buffer absolute max voltage 7.0 V. I found TPD1E1B04 TVS diode having Vrwm = 3.6V , Vbr= 6.4V, Vclamp = 8.5V. For 4 KV ESD, expected current : 15A. As per TLP curve , diode clamping voltage : 8.5V@15A. Does it suitable for our requirement? Please provide your guidance on selection for clamping voltage & peak pulse current parameters.
Also, Does it required unidirectional or bidirectional TVS diode?
Regards,
Ritul
