Product details

1500 W peak pulse, 40.2 V standoff — Zener TVS for general-purpose transient suppression

The 1.5KE47A-T: The 44.7 V minimum breakdown voltage ensures the device starts conducting before the protected rail exceeds the standoff level, while the 64.8 V clamp limits the transient overshoot — a typical fit for 36 V to 48 V DC bus protection in industrial power supplies or telecom rectifiers.

Obsolete — last-time-buy sourcing through independent channels

Diodes Incorporated has marked the 1.5KE47A-T as obsolete. Quantities are lot-specific; availability and pricing are confirmed at RFQ. No second-source cross-reference is maintained by the original manufacturer.

Housed in a DO-201AA (DO-27) axial-lead package with a through-hole mount, the 1.5KE47A-T suits point-to-point wiring or PCB layouts where the lead bend radius and hole diameter follow the DO-201 footprint. The supplier device package is DO-201. The operating junction temperature range spans -55°C to 175°C, covering military-temperature-grade environments such as avionics power buses or engine-bay transient protection where the ambient sees sustained high heat.
