The SMA ZenBlockä BZG142 is designed to protect the MOSFET in flyback converters against over-voltages caused by the transformer leakage inductance. The SMA ZenBlock BZG142combines a zener/TVS with a fast soft-recovery diode in one package, and can be used to replace double diode, RC or RCD snubbers.
The BZG142 consists of a glass passivated chip in a DO-214AC surface mount package.
The well-defined BZG142 void-free case is of a transfer-moulded thermo-setting plastic. The small rectangular package has two J bent leads.
