Qualified to AEC-Q101, this part carries the automotive-grade reliability screening needed for under-hood or chassis-mounted transient protection. ## EOL lifecycle — sourcing the 1.5KE30CHE3/73 now No official successor order code is recorded for this specific variant. Sourcing is per RFQ; availability and date-code provenance are confirmed at quote time. ## Clamping voltage and temperature envelope With a 24.3 V reverse standoff (working voltage) and a 27 V minimum breakdown, the diode begins conducting just above the 24 V rail — clamping at 43.5 V to protect downstream semiconductors rated for 60 V or less. Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE30CHE3/73 is a through-hole device intended for hand insertion or wave-solder assembly. The 1.5KE supplier device package code matches the standard footprint.","metaTitle":"1.5KE30CHE3/73 TVS Diode, 1500W, 24.3V Standoff, Obsolete","metaDescription":"Obsolete 1.5KE30CHE3/73 Vishay TransZorb® TVS, 1500W peak pulse, 24.3V reverse standoff, AEC-Q101.
