The part handles a peak pulse current of 2.1 A at the 10/1000 µs test condition, with the clamping voltage held to 725 V maximum. The bidirectional construction means a single device clamps both polarities — useful on AC lines or DC rails where reverse polarity is possible. ## Package and thermal envelope The wide temperature span suits outdoor telecom enclosures and industrial power supplies where ambient heat and self-heating from repetitive surges must be budgeted together. ## Active production — sourcing posture Littelfuse lists the 1.5KE530CA as Active.","metaTitle":"Littelfuse 1.5KE530CA TVS Diode, 1.5kW, 725V Clamp","metaDescription":"Littelfuse 1.5KE530CA bidirectional Zener TVS, 1500W peak pulse, 725V clamping, DO-201.
