The unidirectional configuration (one channel) is suited for DC power buses where the transient polarity is known — positive spikes above the standoff voltage are shunted to ground, while the forward drop handles negative excursions. This is a common choice for protecting 24 VDC industrial control supplies, telecom rectifiers, or automotive load-dump clamps. ## DO-214AB footprint and temperature range No power line protection feature is claimed — this is a standard TVS for signal or low-impedance DC rails, not a mains-side suppressor. The Tape & Reel packaging suits automated pick-and-place for volume production.","metaTitle":"1.5SMC39A-M3/9AT Vishay TVS, 1500W, 33.3V standoff, DO-214AB","metaDescription":"Active Vishay 1.5SMC39A-M3/9AT TransZorb® TVS, 1500W peak pulse, 33.3V reverse standoff, unidirectional, DO-214AB.
