1500 W pulse rating and automotive qualification
The 1.5KE30CHE3/73 is a 1500 W peak pulse power TVS diode from Vishay's TransZorb® series, rated for a 24.3 V reverse standoff voltage and a 43.5 V maximum clamping point at the 34.5 A peak pulse current (10/1000 µs waveform). 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.
