Product Description

In modern electronic systems,surge protection is an important part of ensuring safe and stable operation of circuits.The SMCJ43A is a high-power transient voltage suppressor diode housed in a surface-mount SMC (DO-214AB) package.It is widely used in various sensitive electronic devices to protect against transient over-voltage caused by lightning strikes, electrostatic discharge (ESD),switching operations,etc.

Key Parameters

  • Standoff Voltage: 43V – It sits quietly on your 43V rail, minding its own business during normal operation.
  • Breakdown Voltage: 47.8V - 52.8V @1mA – The moment voltage spikes past this range, it wakes up instantly and jumps into action.
  • Clamping Voltage: 69.4V at 21.7A – Even during a serious surge, it holds the line to keep your sensitive chips under 69.4V.
  • 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
