Transient suppressor for 256V DC rails
The 1.5KE300CAE3/TR13: This through-hole axial device in a DO-201AA (DO-27) package is designed for general-purpose transient suppression on DC power buses, telecom lines, or industrial control circuits where a single bidirectional device protects against both positive and negative transients.
What the ratings mean for circuit protection
The 256V reverse standoff voltage (VRWM) defines the maximum continuous DC voltage the TVS can withstand without significant leakage — a 250V nominal bus with 5% tolerance sits safely below this threshold. Breakdown voltage is specified at a minimum of 285V, meaning the device begins clamping when the transient exceeds this level, and the clamping voltage is held to 414V maximum at the rated 5A peak pulse current, limiting the voltage stress on downstream components.
Obsolete — sourcing through independent channels
Available through independent surplus and excess inventory channels; each reel is lot-traceable and sourced from franchised or authorized distributor overstock. Quantities are confirmed at RFQ — no standing stock is held.
