500W Zener TVS in Axial Package
The 1N6132A is a bidirectional Zener transient-voltage-suppression diode from Microchip Technology, rated for 500W peak pulse power per the 10/1000µs waveform. Its 91.2V reverse standoff voltage and 165.1V clamping maximum at 3A define the protection window for 91V nominal rails.
Breakdown and Clamping Margins
Minimum breakdown voltage is 114V, giving a ~23V guard band above the standoff level before the diode starts conducting significantly. The clamping ceiling at 165.1V limits the spike seen by downstream components — useful for telecom or industrial DC buses where transients ride on a 91V line.
Active Lifecycle and Sourcing
It is a through-hole axial device.
Temperature Range and Environment
Rated for -55°C to 175°C junction temperature, the 1N6132A suits high-temperature environments such as engine-bay electronics, industrial motor drives, or outdoor telecom enclosures where ambient heat and surge events coincide.
