Additional Details

The TPSMA30-4/5AT features a standoff voltage of 30V, indicating that it remains non-conductive under normal operating conditions up to this voltage. It rapidly becomes conductive when the voltage exceeds 30V, effectively clamping the transient voltage to protect downstream components. The device exhibits a fast response time and a high surge current capability. The SMA package offers ease of assembly and a low profile, making it suitable for applications with height constraints. This TVS diode is RoHS compliant and halogen-free, aligning with environmental regulations.
