Product details

Active production — 1500 W bidirectional TVS in DO-201 axial

The 1.5KE33CA-G: Reverse standoff voltage is 28.2 V typical — this is the DC operating level the diode leaves alone; the avalanche breakdown triggers at 31.35 V min. For a 24 V rail with transients riding up to 28 V, this part sits below the trigger threshold and only conducts during the overvoltage event.

Package and rework — DO-201 axial, through-hole friendly

Housed in a DO-201AA / DO-27 axial-lead package, the 1.5KE33CA-G is a through-hole part with a single bidirectional die — one channel, two leads, no polarity marking needed. The axial body is easy to hand-solder or wave-solder; the leads are thick enough to survive a rework cycle without lifting the pad, and the body orientation is unambiguous because bidirectional parts have no cathode band. The tape-and-box packaging (not reel) suits low-to-moderate volume assembly or prototyping.
