Product details

1500W bidirectional TVS for general-purpose rail clamping

The 1.5KE7.5CA R0G: The reverse standoff voltage of 6.4 V means the diode does not conduct during normal DC operation on a 5 V or 6 V bus. Clamping begins when the voltage exceeds the minimum breakdown of 7.13 V, and the maximum clamp at full rated current is 11.3 V — the voltage the protected circuit must survive without damage.

Active production — current ordering code

The R0G suffix indicates Tape & Reel packaging, suitable for automated assembly. The base product number is 1.5KE7.5, and the CA suffix denotes the bidirectional polarity variant.

DO-201 axial package and temperature range

Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE7.5CA R0G is a through-hole device suited for point-to-point wiring or PCB mounting with lead forming. The supplier device package is designated DO-201.

Frequently asked questions

Is the 1.5KE7.5CA R0G a bidirectional or unidirectional device?

This makes it suitable for AC signal lines or DC rails where reverse polarity protection is also needed.
