1500W bidirectional transient suppressor for 30.8V rails
The 1.5KE36CA-G: It clamps transients at 49.9V maximum when the surge current hits 30.06A, making it a fit for protecting 24V to 30V DC rails in industrial and general-purpose equipment. The reverse standoff voltage of 30.8V means the diode stays transparent below that rail level and only starts conducting when the transient exceeds the minimum breakdown of 34.2V. That 3.4V gap between standoff and breakdown gives normal line ripple and regulation tolerance without leakage.
What the key ratings mean for circuit protection
For shorter pulses like 8/20µs the diode handles significantly more current, but the 10/1000µs rating is the conservative cross-comparison number across manufacturers. If the downstream components have a 50V absolute maximum rating, this diode leaves only 0.1V of headroom — a 60V-rated capacitor bank or a 60V MOSFET gives safer margin. The junction rating is the die temperature, not ambient — derate peak pulse power above 25°C per the datasheet curve.
Package and mounting for through-hole assembly
The through-hole body mounts into a 0.052-inch diameter hole on a standard PCB or terminal strip — no reflow profile needed, just wave solder or hand solder. Packaged in Tape & Box (TB), not tape-and-reel — the leads are taped for axial insertion machines but the box format suits lower-volume hand-load or short-run production. Confirm the feed mechanism on your insertion equipment before committing to the full MOQ.
Active production and sourcing posture
No official second-source or pin-compatible cross-reference is recorded from Comchip. If your BOM needs a second source, parametric equivalents from other brands in the 1.5KE36CA footprint exist — confirm the clamping voltage and breakdown tolerance match your design margin before substituting.
