Product details

1500W transient suppressor for 24V rails

The 1.5KE30A A0G: The 41.4V clamping voltage at the 38A peak pulse current (10/1000µs waveform) defines the maximum voltage the downstream circuit sees during a surge event. This is the number to check against the absolute maximum ratings of the ICs or MOSFETs on the protected rail.

Package, mounting, and temperature range

Housed in a DO-201AA (DO-27) axial-lead package with a DO-201 supplier device case, this is a through-hole part intended for point-to-point wiring or PCB mounting with the leads formed to the hole spacing. The unidirectional configuration (single channel, anode to ground) is the standard choice for DC rail protection where the transient polarity is known. For AC lines or bidirectional clamping, a pair of these or a dedicated bidirectional TVS would be needed.

No pin-compatible second-source or successor is recorded on this line, but the 1.5KE series is a standard JEDEC DO-201 footprint shared by multiple manufacturers.

Frequently asked questions
