What this TVS protects and where it fits
The 1N6465 is a unidirectional Zener TVS diode in a through-hole axial package, designed to clamp transients on a 24 V nominal rail. Its 27 V minimum breakdown voltage and 41.4 V maximum clamping voltage define the protection window: the rail rides at 24 V, the diode starts conducting at 27 V, and the load sees no more than 41.4 V during a surge. Rated for 500 W peak pulse power under the 10/1000 µs waveform and 69 A under the 8/20 µs waveform, this part handles the energy from a typical IEC 61000-4-5 surge on a 24 V industrial or telecom line. The through-hole axial package dissipates heat better than an SMD equivalent, making it a fit for high-surge environments like motor drives, power supplies, and field instrumentation.
Temperature range and operating environment
The 175°C junction temperature rating allows the 1N6465 to operate in high-temperature environments without derating surge capability.
Sourcing and lifecycle posture
