Product details

Automotive-grade bidirectional TVS, DO-214AB

The 1.5SMC170CAHM3_A/I: The single bidirectional channel handles 6.4 A peak pulse current, making it suitable for protecting 145 V nominal rails in automotive and telecom equipment.

Package and temperature envelope

Housed in the DO-214AB (SMC) package, surface-mount on a standard pad layout for 1.5 kW TVS diodes — the copper pad area under the cathode tab sets the thermal impedance. Operating junction temperature spans -65 °C to 150 °C, covering the full automotive underhood ambient range with margin for self-heating during pulse events.

Frequently asked questions
