The 1.5KE7.5CA/B is a bidirectional Zener-type TVS diode from YAGEO's 1.5KE series, designed to clamp transients on general-purpose circuit protection lines. The breakdown voltage range starts at 7.13 V minimum, and the device handles a peak pulse current of 134.5 A under the same test condition.
Package and deployment context
Housed in a DO-201AA / DO-27 axial-lead through-hole package (supplier device package DO-201), it mounts into a standard 0.100-inch pitch board hole pattern. No power line protection is built in — this is a bare TVS diode for signal or low-voltage DC rail clamping, not for AC mains surge suppression.
