Product details

Transient suppression for 300V rails

The 1.5KE350CA B0G: It clamps transients at 482V maximum, with a reverse standoff of 300V and a breakdown voltage of 333V minimum. This part is active in production.

Clamping window and current capacity

With a standoff voltage of 300V, the diode stays transparent on a nominal 300V DC bus and only starts conducting when the line exceeds 333V. The 482V clamp voltage limits the peak voltage seen by downstream components during a surge. The bidirectional configuration means a single device protects against both positive and negative transients — useful on AC signal lines or DC rails where polarity reversal is possible.

Through-hole package and field service

Housed in a DO-201AA (DO-27) axial-lead package, this TVS is through-hole mounted. The axial leads and standard body size make it a straightforward swap on a board — no hot-air station needed, just a soldering iron.
