Additional Details

The 5KASMC30A is typically available in an SMC (DO-214AB) package. The clamping voltage is specified at a particular test current. The operating temperature range is usually from -55°C to +150°C. The device is designed to absorb high energy transients without failure. The peak pulse power dissipation is 5000W. The unidirectional configuration allows for protection against positive polarity transients. The TVS diode operates by clamping the voltage to a safe level when a transient event occurs, diverting the excess current away from the protected components. Selecting the appropriate TVS diode requires careful consideration of the operating voltage, surge current requirements, and clamping voltage levels of the protected circuit. It is very important to choose the correct standoff voltage.
