Transient protection for 100V rails
The 1.5KE120A-G: Its 102V reverse standoff voltage (V_RWM) means it sits across a 100V bus without conducting in normal operation, then clamps a 10/1000µs surge at 165V maximum, passing up to 9.09A of peak pulse current. The 114V minimum breakdown voltage (V_BR) guarantees the avalanche region is entered before the clamp voltage is reached, giving a defined trigger point for the protection.
Package and board integration
Housed in a DO-201AA / DO-27 axial-lead package (supplier device package DO-201), this through-hole part suits point-to-point wiring or PCB mounting where the lead bend radius and hole diameter match the 0.042-inch lead diameter typical of the DO-201 footprint.
