Product details

Obsolete — the sourcing reality for this 1.5kW TransZorb

The 1.5KE9.1C-E3/54: Availability and date-code provenance are confirmed at quote time, not before.

Protection thresholds — what the ratings mean for the circuit

As a bidirectional Zener TVS in the TransZorb series, the 1.5KE9.1C-/54 clamps transients on both polarities — useful for AC lines or DC rails where the fault polarity is unknown. The reverse standoff voltage of 7.37 V means the diode stays off below that level, drawing negligible leakage current.

Housed in a DO-201AA (DO-27) axial-lead through-hole package, the 1.5KE9.1C-/54 mounts into a standard 0.100-inch pitch board hole — the same footprint used across the 1.5KE series.
