Obsolete TVS — sourcing reality for the 1.5KE62ARL4G
The Littelfuse 1.5KE62ARL4G is an obsolete Mosorb™ Zener TVS diode — the manufacturer has discontinued this order code, so new production is not available through the factory channel. Sourcing runs through independent surplus and broker inventory.
Protection window and pulse capability
The 53 V reverse standoff voltage is the maximum DC or AC peak the protected line can carry without the TVS conducting in standby.
Housed in a DO-201AD axial-lead through-hole package — the body is large enough to dissipate the pulse energy without lifting the pad under a hot-air rework station, but the axial leads mean the part stands off the board and needs mechanical support against vibration. Operating temperature range spans -65°C to 175°C junction — wide enough for under-hood automotive or industrial outdoor enclosures where the ambient sees thermal cycling.
