Product details

1500 W Zener TVS in DO-201 axial

The 1.5KE24CA-T from Diodes Incorporated is a 1500 W peak-pulse-power Zener TVS diode in a through-hole DO-201AA (DO-27) axial package. It provides a single bidirectional channel, clamping transients on a 20.5 V nominal rail to 33.2 V maximum at the rated 45 A peak pulse current (10/1000 µs waveform).

Clamping voltages and pulse capability

The reverse standoff voltage is 20.5 V typical, meaning the diode draws negligible leakage below this rail voltage. The operating junction temperature range spans -55°C to 175°C, suiting it for industrial and automotive environments where ambient heat and self-heating from repetitive surges must be budgeted.

Obsolete — sourcing through independent channels

Diodes Incorporated lists the 1.5KE24CA-T as obsolete.
