Bidirectional 1.5 kW transient suppressor for general-purpose rail clamping
The 1.5KE18C-E3/73: It is marked as general-purpose and suits DC power buses, signal lines, and low-voltage supplies in industrial and telecom equipment.
Parametric envelope and package
Breakdown voltage range starts at 16.2 V minimum, ensuring the device begins conducting before the protected rail reaches damaging levels. The 14.5 V reverse standoff voltage is the maximum DC or peak-AC voltage the TVS can withstand without significant leakage — design the protected line to stay at or below this value. Housed in the DO-201AA (DO-27) axial-lead package, it supports through-hole mounting with a 1.5KE supplier device package code.
Obsolete — sourcing through independent channels
For existing BOM lines or repair stock, the device is available through independent surplus and broker channels.
