Product details

10V rail clamp with 11.1V breakdown floor

Its minimum breakdown voltage of 11.1V ensures the device starts clamping before the protected circuitry sees overvoltage, while the 17V maximum clamping voltage at 29.4A peak pulse current limits the let-through energy during a surge event.

Active production — no EOL clock yet

The - suffix indicates RoHS compliance and lead-free termination finish, confirmed by the product marking.

Wide temperature tolerance for harsh environments

The 500W peak pulse power rating is derated at elevated temperatures per the datasheet curve — at 150°C the derating factor reduces the peak pulse power to approximately 50% of the 25°C rating.

Frequently asked questions

Is SMAJ10AE3/TR13 RoHS compliant?

Yes, the - suffix in the order code indicates RoHS compliance and lead-free termination finish. The part is supplied in Tape & Reel packaging and is suitable for lead-free soldering processes.

What is the peak pulse power of SMAJ10AE3/TR13?

500W peak pulse power for a 10/1000µs waveform. This rating defines the surge energy the device can absorb in a single transient event before failure.

What is the difference between SMAJ10A and SMAJ10CA?

SMAJ10A is a unidirectional TVS (single diode for one polarity), while SMAJ10CA is a bidirectional TVS (two Zener diodes back-to-back for AC or bipolar rail protection). The SMAJ10AE3/TR13 is the unidirectional variant, suitable for DC rails where the signal stays above ground.
