Product details

Breakdown, clamp, and pulse current — the protection envelope

The 1.5KE11CAH: At the 100A peak pulse current (10/1000µs waveform), the clamping voltage is 15.6V max. The 1500W peak pulse rating defines the energy-handling capability at the 10/1000µs waveform. For shorter pulses (8/20µs), the peak power is higher; for longer events, derate accordingly. The DO-201AA axial package has a low thermal resistance to the leads — the copper trace area on the PCB determines how much steady-state heat the part can sink during repetitive surges.

Active production, automotive-grade traceability

The AEC-Q101 qualification provides lot traceability and reliability data (temperature cycle, HTRB, H3TRB) per the automotive PPAP framework.

Frequently asked questions

Where can I buy 1.5KE11CAH and how is it quoted?

Submit an RFQ for a firm quote with lead time.

What is the closest pin-compatible alternative to 1.5KE11CAH in this Circuit Protection family?

The 1.5KE series includes other bidirectional TVS diodes with different standoff voltages — a parametric search by package (DO-201AA) and power rating (1500W) will identify functionally similar parts, but pinout compatibility is guaranteed only within the same order code.

What compliance documentation does Taiwan Semiconductor Corporation provide for 1.5KE11CAH?

Taiwan Semiconductor Corporation provides RoHS and REACH compliance documentation for the 1.5KE11CAH. The AEC-Q101 qualification includes the associated reliability test reports (temperature cycling, HTRB, H3TRB).
