When a transient exceeds the breakdown threshold of 83.3V min, the diode clamps at 121V maximum while conducting 4.1A peak pulse current (10/1000µs waveform), absorbing 500W peak pulse power.
The Tape & Reel (TR) packaging suits automated pick-and-place assembly. The suffix in the order code indicates RoHS compliance — no lead, no restricted substances per the directive.
Yes. The suffix in the order code designates RoHS compliance per Microchip's standard.
No. This is a unidirectional device (one channel). For bidirectional protection on the same rail, look at the SMAJ75CA family — same package, same power rating, but back-to-back Zener structure.
The suffix indicates RoHS compliance. The SMAJ75A (without) is the non-RoHS variant; electrical specifications are identical. The SMAJ75AE3/TR13 is the RoHS-compliant version on Tape & Reel.
