Transient suppressor for 20.6V rails – 500W bidirectional clamp
Its 500W peak pulse power rating (10/1000µs waveform) means it can absorb a single high-energy surge without failing, making it a fit for power supply inputs, relay coil suppression, or general-purpose board-level protection where the operating voltage stays under 20.6V.
Minimum breakdown voltage is 25.7V, so the device begins conducting when the line exceeds that threshold. For a 20.6V rail, the 37.4V clamp gives about 17V of headroom above the normal operating level, which is typical for a 20% margin design.
Through-hole axial package – mounting and thermal path
Housed in a B, Axial package with through-hole mounting, the 1N6116A is a leaded device that solders into a plated through-hole on the PCB.
Active production – sourcing and lifecycle posture
The base product number is 1N6116; the 'A' suffix typically indicates a tighter tolerance or improved specification over the base 1N6116.
