Obsolete — last-time-buy sourcing for the 1.5KE7.5-E3/54
Vishay has marked the 1.5KE7.5-/54 as obsolete — the manufacturer no longer produces this TransZorb TVS diode. Sourcing now runs through independent surplus and broker channels; quantities are confirmed lot-specific at RFQ time.
Clamp voltage and pulse handling for 6V rail protection
With a 6.05V reverse standoff voltage, it sits across a 5V or 6V DC rail and stays transparent until a transient drives it into avalanche at 6.75V minimum breakdown. The clamp voltage peaks at 11.7V at the full 128A peak pulse current — this is the voltage the downstream circuitry must survive without latch-up or oxide rupture.
Through-hole axial package and temperature range
The wide Tj envelope suits it for environments where ambient heat and transient energy stack: industrial PSU secondary-side clamping, telecom line cards, and automotive auxiliary rails that see under-hood soak temperatures.
Sourcing this obsolete TVS for your BOM line
Because Vishay has discontinued the 1.5KE7.5-/54, no new factory orders are accepted. Our desk sources this part through independent surplus inventory — each reel is traceable and inspected for authenticity before shipment. Submit an RFQ for your target quantity; we confirm availability, date code range, and pricing per lot at quote time.
