1500 W peak pulse protection in a DO-201 axial body
The 1.5KE30CA/B: The 25.6 V reverse standoff voltage means it stays transparent on a nominal 24 V rail, only conducting when the line exceeds the 28.5 V minimum breakdown threshold.
What the clamping voltage means for your rail protection
With a maximum clamping voltage of 41.4 V at the rated 36.7 A peak pulse current, this part keeps a 24 V bus within the safe operating area of typical downstream components rated for 50 V or higher. The bidirectional configuration (single channel) protects against both positive and negative transients without needing a series diode — useful on AC signal lines or DC rails where reverse polarity is a risk. The operating temperature range spans -55°C to +150°C junction, so it survives the thermal cycling of outdoor telecom cabinets or under-hood automotive environments without derating the peak power at the high end.
