Product details

1500 W bidirectional transient suppressor

The 1.5KE180CA-E3/54: The single bidirectional channel protects both polarities with one device, simplifying the BOM on AC signal lines or DC rails where the polarity is unknown or can reverse.

DO-201 axial package and thermal envelope

Housed in a DO-201AA (DO-27) axial-leaded through-hole package, the 1.5KE180CA-/54 dissipates the 1500 W pulse through the lead frame and body — the large junction-to-lead thermal path is designed for single-pulse events, not continuous DC dissipation. The through-hole mounting allows the axial leads to be soldered into plated through-holes on a standard PCB or wired into a terminal block — the lead bend radius should be at least twice the lead diameter to avoid cracking the glass passivation layer on the die.

Frequently asked questions

Where can I buy the 1.5KE180CA-/54 and how is it quoted?

The 1.5KE180CA-/54 is sourced through authorized and independent distribution channels.

What does the 154 V standoff rating mean for my circuit?

Below 154 V, the device is effectively an open circuit. Above 171 V (the minimum breakdown), it begins to avalanche and clamp the transient. The 246 V clamping voltage is the maximum voltage the protected circuitry will see during a 6.1 A peak pulse event.

Is this part suitable for power line protection?

No, the 1.5KE180CA-/54 is not rated for power line protection. It is intended for signal and data line transient suppression where the energy is limited to single-pulse events. For AC mains protection, a higher-energy MOV or a TVS rated for continuous AC operation would be required.
