Product details

Zener TVS for 8 V rail protection

The SMAJ8.0AE3/TR13 is a unidirectional Zener-type transient voltage suppressor from Microchip, designed to clamp voltage spikes on general-purpose 8 V DC rails. Its 500 W peak pulse power rating (10/1000 µs waveform) covers common surge events in industrial control, telecom, and consumer power inputs. With an 8 V reverse standoff voltage, the TVS remains transparent during normal operation and begins avalanche breakdown at a minimum of 8.89 V. The clamping voltage is held to 13.6 V maximum at the rated peak pulse current of 36.7 A.

Supplied in a DO-214AC (SMA) surface-mount package, the SMAJ8.0AE3/TR13 is delivered on Tape & Reel (TR) for automated pick-and-place assembly.

Lifecycle and availability

Microchip lists the SMAJ8.0AE3/TR13 as Active in production.

Frequently asked questions

Is SMAJ8.0AE3/TR13 equivalent to SMAJ8.0A?

The base product number is SMAJ8.0. The '' suffix indicates Microchip's lead-free / RoHS-compliant finish, and '/TR13' specifies Tape & Reel packaging. Electrically, the SMAJ8.0AE3/TR13 shares the same 8 V standoff, 8.89 V breakdown, and 13.6 V clamp as the standard SMAJ8.0A — the difference is the environmental compliance and reel format.

Is SMAJ8.0AE3/TR13 RoHS compliant?

Yes, the '' suffix in the order code designates Microchip's RoHS-compliant / lead-free finish. The part is suitable for lead-free soldering processes.
