The 6.9 V gap between standoff and clamp means the protected circuit must survive a 21.2 V transient while the rail normally runs at 12.8 V. The single bidirectional channel handles both polarities without needing two series-connected unidirectional parts. ## Operating environment and package reality Rated for junction temperatures from -55°C to 175°C (TJ), the 1.5KE15CA B0G handles the thermal cycling typical of outdoor telecom, industrial power supplies, and automotive under-hood environments where ambient temps push past 85°C. The DO-201AA (DO-27) axial through-hole package — supplier device package DO-201 — is a standard leaded form factor that hand-solders easily and fits existing THT layouts without a board spin. Bulk packaging means the parts ship loose in a bag or tube, not taped and reeled; factor this into pick-and-place planning if you're running a high-volume SMT line with a through-hole inserter. The device is not rated for power line protection (Power Line Protection: No) — it is intended for secondary-side transient suppression on DC buses, signal lines, and low-voltage AC circuits, not for direct mains clamping where higher-energy movistors or gas discharge tubes are required.","metaTitle":"1.5KE15CA B0G TVS Diode, 1500W Bidirectional, DO-201","metaDescription":"1.5KE15CA B0G bidirectional TVS, 1500W peak pulse, 12.8V standoff, 21.2V clamp.
