Bidirectional TVS for 110V rails — clamping at 182V
The 1N6066A is a bidirectional Zener TVS diode from Microchip Technology, designed to clamp transients on symmetrical AC or DC lines. Its 110V reverse standoff voltage means it sits across a 110V nominal rail without conducting, and when a surge hits, it clamps at 182V maximum while shunting 8.2A of peak pulse current in the 10/1000µs waveform. The 1.5 kW peak pulse power rating gives you a rough energy budget — enough for secondary lightning surge protection on industrial controls or telecom line cards, but not a primary mains protector. The bidirectional channel means you can drop it across an AC signal pair without worrying about polarity; no orientation guesswork in the field.
DO-13 through-hole — field-swappable, no hot air needed
The DO-13 package is a metal-can through-hole case, same footprint as the classic 1N60xx series. Through-hole means you can swap it on site with a soldering iron and a desoldering pump — no hot-air station, no lab bench. The junction temperature range spans -55°C to 175°C, so it survives the thermal cycling you see in outdoor cabinets or engine bays. No power line protection — this part is designed for signal or low-power DC/AC rails, not mains AC. If you are protecting a 120V AC input, the 110V standoff is close but the clamping at 182V may not leave enough margin for a 170V peak rectified waveform; check your transient profile against the clamp voltage.
Active production — no end-of-life clock ticking
