What this Zener diode protects and where it fits
The 1N6069A is a single-bidirectional-channel Zener diode rated for 1500W peak pulse power. It clamps transients at 261V maximum, with a reverse standoff voltage of 150V and a minimum breakdown of 171V. The DO-13 through-hole package suits point-of-use clamping on power rails in industrial or telecom equipment where board space is not the constraint.
Peak pulse power and voltage ratings for the BOM
The 1500W peak pulse power rating at 10/1000µs defines the surge energy the diode can absorb without failure — critical for selecting the right protection for a 150V rail. The 261V clamping voltage sets the maximum voltage the downstream circuitry sees during a transient event; a 171V breakdown minimum ensures the diode starts conducting before the rail exceeds its safe operating area. The 5.7A peak pulse current rating at the same waveform gives the current-carrying capacity during the surge.
Active lifecycle and sourcing posture
The DO-13 package is a standard through-hole footprint, so second-source equivalents from other manufacturers may exist, but no official cross-reference is listed. Sourced per RFQ against your BOM quantity; confirm the exact voltage and package variant before committing.
