Product details

Transient suppressor for 36V rails

It clamps at 54.3V maximum at 23A peak pulse current, making it suitable for protecting 36V nominal DC buses or AC lines against surges. The single bidirectional channel means the part handles both positive and negative transients without polarity concern — useful for floating or AC-coupled lines.

Breakdown and clamping — what the numbers mean for your BOM

The minimum breakdown voltage of 42.4V sets the threshold where the device starts conducting; below that, it looks like an open circuit to the protected line. The maximum clamping voltage of 54.3V at 23A tells you the worst-case voltage the downstream circuitry sees during a surge — ensure your load's absolute maximum rating exceeds this. The 1500W peak pulse rating at 10/1000µs is the energy-handling capability; a shorter pulse (e.g. 8/20µs) allows higher peak current, but the 10/1000µs rating is the standard comparison point for telecom and industrial surge specs.

DO-13 through-hole — legacy footprint considerations

The DO-13 package is a through-hole, hermetically sealed metal can with two leads. It requires a 0.052-inch diameter hole on 0.200-inch lead spacing — verify existing board drill files before committing. Operating temperature range of -65°C to 175°C (junction) covers extreme environments: avionics, downhole, or outdoor telecom cabinets where the ambient can swing wide. No power line protection rating — this part is not designed for AC mains surge suppression; keep it on DC or signal-level buses.

Frequently asked questions

Is 1N6371/TR bidirectional?

Yes — it has one bidirectional channel. That means it clamps equally on positive and negative transients, so polarity does not matter during installation. Use it on AC signal lines or floating DC buses where the surge polarity is unknown.

Can I replace 1N6371 with 1N6371/TR on my BOM?

The 1N6371 and 1N6371/TR share the same silicon die and electrical ratings. The only difference is packaging: 1N6371/TR is supplied on Tape & Reel for automated assembly, while the non-suffix variant typically ships in bulk tubes. If your pick-and-place handles taped through-hole parts, the /TR version is a drop-in replacement. Confirm the carrier format with your line before switching.
