Product details

Package and rework — axial leaded, bench-friendly

The 1.5KE120CA R0G: Housed in a DO-201AA (DO-27) axial leaded package with a DO-201 supplier device code, this is a through-hole part. The leads are long enough to form and trim for board mounting, and the body is large enough to read the marking without magnification. Pin 1 is the cathode band; the bidirectional construction means polarity doesn't matter for clamping, but the band still identifies the cathode for test.

The 175°C TJ max gives margin above the 125°C typical for many TVS parts — useful when the ambient around the PCB hits 85°C and the self-heating from repetitive surges adds another 40-50°C.
