Product details

Clamping and protection ratings

The 1.5SMC82CA V7G: The 70.1 V standoff rating is the working reverse voltage the diode blocks continuously without conducting; the 77.9 V minimum breakdown is where it begins to clamp. 1.5 kW peak pulse rating defines the energy the device can survive at the specified pulse width — for telecom line cards running outdoors or near inductive kick paths, this rating confirms headroom above typical secondary-surge events.

Package and telecom fit

DO-214AB (SMC) is the standard uni-directional/tvSB package for 1.5–3 kW TVS devices — the foot pattern mates with common TVS land patterns on telecom PHY boards and power-supply input stages. Surface-mount reflow profile matches standard SAC305 paste schedules. Telecom is the listed application class — these are typically found on DC power rails feeding DSL, fibre, or base-station modules where lightning-induced surges or ESD from long cable runs must be clamped at the board entry point.

Active production and sourcing

Taiwan Semiconductor Corporation marks this part Active. Operating junction temperature runs to 150 °C, giving margin for thermally challenging enclosures or outdoor cabinet deployments. The -55 °C lower limit covers outdoor cabinet cold-start conditions; the 150 °C junction ceiling is set by the die attach and epoxy system, not the silicon bandgap — derate peak pulse power below the curve if the case temperature climbs.

Frequently asked questions

What is 1.5SMC82CA V7G's listed type?

The part is classified as a Zener bidirectional TVS diode in the 1.5SMC series.

What is the 1.5SMC82CA V7G used for?

Telecom is the stated application — TVS diodes in this voltage range protect DC power rails and signal lines on telecom equipment from surge and ESD events, typically at the board entry point upstream of sensitive PHY circuits.
