1.5kW bidirectional transient suppressor in a DO-201 axial body
The 1.5KE82CA B0G: The 70.1V reverse standoff voltage means it sits across a 48V or 60V rail without conducting in normal operation; only a transient exceeding 77.9V breakdown triggers the clamp. The DO-201AA (DO-27) axial body handles the 1500W pulse without package rupture, provided the lead length is kept short to minimise inductive overshoot.
Active production — no end-of-life watch needed
Taiwan Semiconductor Corporation lists the 1.5KE82CA B0G as Active. For a storeroom stocking decision, this part is still a standard catalogue item — no urgency to hoard a lifetime buy. This covers the full industrial and telecom ambient envelope, including the hot side of an outdoor enclosure or an unvented power supply bay.
