Single bidirectional channel — one device clamps both polarities, which simplifies PCB layout on AC or bipolar DC lines compared to back-to-back unidirectional TVS diodes. ## Through-hole mounting and thermal envelope Operating junction temperature spans -50 °C to +175 °C — wide enough for outdoor telecom cabinets, industrial power supplies, and motor-drive DC buses where ambient heat and self-heating from repetitive surges stack. ## Sourcing and lifecycle posture No official second-source or successor cross-reference is recorded — the part is specified as-is for the protection requirement.","metaTitle":"Diotec 1.5KE440C Bidirectional TVS, 1.5kW, DO-201","metaDescription":"Diotec Semiconductor 1.5KE440C bidirectional TVS diode, 1500W peak pulse power, 356V standoff, 631V clamping.
