DO-214AB (SMC) surface-mount package with the SMC/DO-214AB supplier foot print — the cathodes bar on the package body marks the anode side in the standard polarity convention.","metaTitle":"Diotec 1.5SMCJ33CA-AQ 33V TVS Diode, 1.5kW","metaDescription":"Diotec 1.5SMCJ33CA-AQ bidirectional TVS diode, 33V standoff, 1.5kW peak pulse, DO-214AB SMC package, automotive grade -50 to 150°C.
