The bidirectional configuration means a single part clamps positive and negative surges equally — useful on AC signal lines or floating DC buses where polarity reversal is possible. ## DO-201 axial package — board integration Housed in a DO-201AA (DO-27) axial-lead through-hole package with a DO-201 supplier device code. No power line protection claim — this is a secondary-side transient suppressor, not a primary AC mains protector. Use it on DC power inputs, signal lines, or low-voltage AC rails downstream of the main fuse. Marked active in production by Taiwan Semiconductor. Sourced through independent and authorized distribution channels. Availability and current pricing confirmed against an RFQ; the DO-201 package is common across multiple TVS families, so alternate sourcing is straightforward.","metaTitle":"1.5KE22CA A0G TVS Diode, 1.5kW, Bidirectional, DO-201","metaDescription":"Taiwan Semiconductor 1.5KE22CA A0G bidirectional TVS, 1500W peak pulse power, 18.8V standoff, 30.6V clamp.
