Additional Details

The 5KASMC33A is available in an SMC (DO-214AB) package. The clamping voltage is specified at a particular test current, and the operating temperature range is generally from -55°C to +150°C. This TVS diode is engineered to absorb high-energy transients without experiencing catastrophic failure, ensuring continued protection. The peak pulse power dissipation is rated at 5000W. Its unidirectional configuration provides protection against positive polarity transients. Key to selecting this diode is the correct standoff voltage. Similar to other TVS diodes it should be carefully selected based on the required surge current, voltage level, and clamping level of the protected circuit.
