The bidirectional structure (single device, one channel) clamps both polarities, so a single part covers the rail-to-ground and reverse-polarity fault paths without a series diode. ## 1500 W pulse rating and clamping behaviour At 4 A peak pulse current (10/1000 µs), the clamping voltage holds at 482 V maximum — this is the voltage the protected circuit must survive across the TVS during the transient event. The 332 V minimum breakdown voltage provides a 32 V guard band above the 300 V standoff, ensuring the device does not conduct at nominal rail voltage but triggers before the transient exceeds the downstream component's absolute maximum rating. Rated for continuous operation from -65°C to 150°C junction temperature, the part handles the self-heating from repetitive pulses in high-ambient environments like outdoor telecom cabinets or industrial enclosures without derating below the 1500 W peak. ## DO-201 axial package for through-hole assembly Housed in a DO-201AA (DO-27) axial-lead package, the 1.5KE350CAE3/TR13 mounts through-hole — the body is cylindrical with wire leads for hand or wave solder, common in high-reliability power supplies where a surface-mount TVS might not survive the reflow profile or board flex. ## Obsolete — sourcing through independent channels No pin-compatible direct replacement is documented by Microsemi — a functional equivalent would need to match the 1500 W peak pulse, 300 V standoff, bidirectional polarity, and DO-201 axial footprint.","metaTitle":"Microsemi 1.5KE350CAE3/TR13 TVS, 1500W, 300V Standoff","metaDescription":"Microsemi 1.5KE350CAE3/TR13 bidirectional TVS diode, 1500W peak pulse power, 300V reverse standoff, 482V clamping.
