1500W Zener TVS – DO-13, bidirectional, 22V standoff
The 1N6370/TR: It is a single bidirectional channel with a reverse standoff voltage of 22V, a minimum breakdown voltage of 25.9V, and a maximum clamping voltage of 32V at 40A peak pulse current.
Bidirectional clamp – one part covers both polarities
Unlike unidirectional TVS diodes that protect only one polarity, the 1N6370/TR's single bidirectional channel clamps both positive and negative transients, simplifying board layout and reducing component count on AC or bipolar DC rails. The 22V standoff voltage means the diode does not conduct during normal 12V or 15V rail operation, only clamping when the line exceeds the 25.9V breakdown threshold – a typical choice for 24V industrial buses or automotive 24V systems.
DO-13 through-hole – rugged for high-reliability assemblies
The DO-13 package is a hermetic metal can with a glass seal, offering superior moisture resistance and mechanical robustness compared to plastic SMD packages – relevant for military, aerospace, or downhole applications where long-term reliability is critical. Supplied on Tape & Reel (TR), though the through-hole format typically requires hand-insertion or selective-solder processes in production.
