Product details

70V rail transient suppressor in DO-214AC

This unidirectional device suits general-purpose protection where the protected line stays above ground, such as DC power inputs, industrial control buses, or telecom line cards.

Peak pulse current and temperature range

Rated for 4.4A peak pulse current under the 10/1000µs waveform, the SMAJ70AE3/TR13 operates across -65°C to 150°C junction temperature, covering the full industrial and automotive under-hood envelope. The 500W peak pulse power defines the energy-absorption ceiling for a single transient event — derate for repetitive pulses per the datasheet curve.
