Product Description

The SMCJ220A is a 1500W unidirectional TVS diode in the standard DO-214AB (SMC) package. Designed to protect sensitive electronics, it clamps high-energy transients and surges from lightning, ESD, and inductive switching. With a 220V standoff voltage, it is a direct, reliable, and cost-effective replacement for equivalent parts from NXP and Littelfuse, ensuring robust circuit protection in industrial, automotive, and telecom applications.

Key Parameters

  • Standoff Voltage: 220V – It sits quietly on your 220V rail, minding its own business during normal operation.
  • Breakdown Voltage: 246 - 272V @1mA – The moment voltage spikes past this range, it wakes up instantly and jumps into action.
  • Clamping Voltage: 356V at 4.2A – Even during a serious surge, it holds the line to keep your sensitive chips under 356V.
  • Peak Pulse Power: 1500W – This thing absorbs brutal transient energy like a miniature surge superhero.
  • Ultra-low leakage: Just 1µA – It barely sips any power, so it won’t load your circuit or waste energy.

Typical Applications

  • Industrial Electronics: Protection for PLCs, motor drives, and control systems.
  • Telecommunications: Safeguarding communication lines and data interfaces.
  • Automotive Systems: Protecting ECUs, sensors, and CAN bus networks.
  • Power Supplies: Preventing damage from inductive load switching.
  • Consumer Electronics: Shielding sensitive circuits in appliances and computing devices
