1500 W bidirectional TVS in a DO-201 axial package
The 1.5KE160CA-B: Housed in a DO-201AA (DO-27) axial-lead package, it is intended for through-hole mounting and supplied in bulk — a form factor common in industrial power supplies, telecom rectifiers, and heavy-equipment control boards where board space is less constrained.
Clamping, breakdown, and operating limits
Breakdown occurs at a minimum of 152 V, ensuring the device begins conducting before the protected rail exceeds that threshold. The 219 V clamping voltage limits the peak voltage seen by downstream components during a surge event. The single bidirectional channel protects both polarities in a single package, simplifying layout for AC or bipolar DC lines. Note that this part does not include power line protection features — it is a general-purpose transient suppressor, not a dedicated AC mains protector.
Obsolete — sourcing through independent channels
Diodes Incorporated has marked the 1.5KE160CA-B as obsolete. No official successor part number is recorded in the manufacturer's lifecycle data. For sustainment of existing BOMs, this part is available through independent distribution — sourced against an RFQ with lot traceability and date-code confirmation.
