Product details

TVS selection — 15V rail protection in a surface-mount SMA

Its 16.7V minimum breakdown voltage and 24.4V clamping at 20.6A peak pulse current define the protection window for a 12V or 15V supply bus. Rated for 500W peak pulse power under the 10/1000µs waveform, this part handles common industrial and telecom surge events without exceeding the junction temperature range of -65°C to 150°C.

Package and mounting — DO-214AC (SMA) on tape and reel

Supplied in tape and reel (TR) packaging, the SMAJ15AE3/TR13 uses the DO-214AC (SMA) surface-mount package — a low-profile, two-terminal footprint compatible with standard reflow soldering. No power line protection feature is integrated; this is a dedicated transient suppressor for signal or low-voltage DC rails, not for AC mains.

Frequently asked questions

Is the SMAJ15AE3/TR13 RoHS compliant?

The evidence does not list a specific RoHS status, but Microchip's standard TVS portfolio is generally RoHS-compliant. Confirm with the datasheet or your Microchip representative for this exact ordering code.
