With a 28.2 V reverse standoff voltage, this part sits on a 24 V rail or a 28 V signal line and stays off until a transient exceeds 31.4 V (the minimum breakdown voltage). ## Bidirectional clamping — one device for both polarities This is a single bidirectional channel — the Zener structure clamps equally on positive and negative transients. That matters for AC-coupled signal lines, bipolar data buses, or any board where the surge polarity is unknown, because one part covers both directions instead of needing two unidirectional diodes back-to-back. The DO-201AA (DO-27) axial package is a through-hole form factor with a 0.052-inch lead diameter typical. Note that the spec explicitly states 'no power line protection' — this part is intended for secondary surge suppression on signal or DC power lines, not for clamping AC mains transients directly.","metaTitle":"YAGEO 1.5KE33CA/B TVS Diode, 1500W, 28.2V Standoff, DO-201","metaDescription":"YAGEO 1.5KE33CA/B bidirectional TVS diode, 1500W peak pulse power, 28.2V standoff, 45.7V clamping.
