A single bidirectional channel protects both polarities — useful for AC signal lines, bipolar DC buses, or any application where the surge polarity is unknown. The DO-201AA (DO-27) axial-lead through-hole package suits point-to-point wiring or PCB mounting where a robust mechanical anchor is preferred over surface-mount. ## Active production, wide temperature range The bulk packaging means reels are not split; order the full BOM quantity. No moisture sensitivity level (MSL) concern for axial-lead glass-passivated parts — store in standard dry conditions, no bake required before soldering. ## Clamping voltage and pulse current — the protection envelope A 24V DC bus with 20% tolerance reaches 28.8V at the high end; the 30.6V clamp leaves 1.8V of headroom before the downstream regulator's abs-max rating — tight but workable if the regulator is rated for 36V or higher. The 1500W rating at 10/1000µs is the standard TVS pulse — derate for shorter or longer pulse widths per the manufacturer's pulse-derating curve.","metaTitle":"1.5KE22CA B0G TVS Diode, 1500W, 18.8V, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE22CA B0G bidirectional TVS, 1500W peak pulse, 30.6V clamp, DO-201 axial.
