.The P4SMAJ36A-AQ with ESD Suppressors / TVS Diodes TVS Diode, SMA, 36V, 400W, Unidir is an ESD suppressor diode manufactured by Diotec. This diode is a Transient Voltage Suppression diode designed to protect against the transient events caused by electrostatic discharge. It is an ultra-fast, surface-mount device with 400W surge capability, a SMA-package, and a 36V unidirectional breakdown voltage. This diode is ideal for use in ESD protection applications, as it quickly and safely dissipates the ESD generated voltage/current before it can damage electrical and electronic components.
