Transient suppressor for 162 V rails — what the ratings mean
The 1.5KE200C-E3/73: Its 162 V reverse standoff voltage means it sits across a 162 V DC or 115 V AC nominal rail without conducting; the 180 V minimum breakdown voltage is where clamping begins.
Package and board integration
Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE200C-/73 mounts into a 1.1 mm diameter hole on a standard PCB or terminal strip. The axial leads allow either vertical or horizontal mounting; the body length and lead spacing suit point-to-point wiring in power supplies and industrial control boards.
No official successor order code is recorded on the lifecycle notice.
Rated for continuous junction operation from -55°C to +175°C, the 1.5KE200C-/73 suits outdoor telecom cabinets, industrial power supplies, and automotive under-hood environments where ambient temperatures exceed 85°C. The 1500 W peak pulse rating is derated linearly above 25°C; at 175°C the derated capability drops to approximately 20% of the 25°C rating, so the thermal environment must be factored into the transient budget.
