What is ATV254-CuH-S used for?

It is intended for isolated load and signal switching in industrial automation, appliances, communications or security equipment, and suitable equipment-control circuits.

What should engineers review before using ATV254-CuH-S?

Check the 400 V peak AC output-voltage limit, 0.13 A continuous-current limit, 30 Ω maximum on resistance, temperature derating, and the specified turn-on and turn-off timing.

What is the pinout of ATV254-CUH-S?

Use the ATV254-CUH-S datasheet for the official pinout diagram and pin names. In PartGenie, ask Datasheet AI about ATV254-CUH-S pinout to locate pins, power rails, and interface signals before layout.

AI summary

ATV254-CuH-S is an SMD-6 optically isolated MOSFET-output relay for switching loads up to 400 V peak AC and 0.13 A continuous current.

Best for

Low-current isolated AC load switching
Space-constrained SMD control boards
Applications requiring 5,000 Vrms isolation

Avoid if

Low-loss switching is required at the maximum load current
Fast or tightly controlled switching timing is required
Lifecycle-qualified sourcing is mandatory without further supplier confirmation

Check before use

Calculate dissipation at the maximum expected current using worst-case 30 Ω on resistance.
Check load-current derating versus ambient temperature.
Confirm PCB creepage, clearance, and isolation requirements for the application.
