Product details

TVS diode, 1500W, bidirectional, 20.5V standoff

The 1.5KE24CA B0G: With a 20.5V reverse standoff voltage and 22.8V minimum breakdown, it clamps transients to 33.2V maximum at 47A peak pulse current. The bidirectional configuration (single channel) means a single device protects both polarities — useful on AC signal lines or DC rails where the polarity can reverse during a surge.

Package and temperature range

Housed in a DO-201AA (DO-27) axial-lead package, the DO-201 suffix indicates the standard body size for the 1.5KE family — through-hole mounting suits point-to-point wiring or PCB insertion with 0.040-inch lead diameter.

Frequently asked questions

Is 1.5KE24CA B0G unidirectional or bidirectional?

Bidirectional — a single channel protects against both positive and negative transients, making it suitable for AC signal lines or DC rails subject to reverse surge events.
