The SA70A is a unidirectional transient voltage suppression (TVS) diode designed by Littelfuse to protect sensitive electronic equipment from voltage transients induced by lightning and other transient events. It belongs to the SA series with a peak pulse power capability of 500W (10/1000µs waveform) and a fast response time of less than 1.0ps from 0V to breakdown.
Key electrical characteristics include a reverse standoff voltage of 70V, a maximum clamping voltage of 113V at the rated peak pulse current of 4.5A, and a peak forward surge current of 70A (8.3ms). The device is unidirectional with glass passivated chip junction and features low incremental surge resistance.
The SA70A is housed in a DO-204AC (DO-15) axial leaded package designed for through-hole mounting. It operates over a junction temperature range of -55°C to 175°C with a maximum steady state power dissipation of 3.0W on infinite heat sink at lead temperature 75°C. The package is halogen free, RoHS compliant, and has a flammability rating of V-0 per UL.
