Vishay 1-Element Uni-Directional Transient Voltage Suppressor 400 W 2-Pin DO-214AC SMAJ30A-E3/61

Vishay SMAJ30A-E3/61 is a 1-element uni-directional transient voltage suppressor (TVS) designed to protect sensitive electronic components from electrostatic discharges and transient voltage spikes. It is rated for a peak pulse power dissipation of 400 W and packaged in a compact 2-pin DO-214AC (SMA) surface mount package, suitable for automated assembly in industrial and automotive electronics.

This TVS diode features a single-element design with a minimum breakdown voltage (Vbr) of 33.3 V, a maximum reverse stand-off voltage (Vwm) of 30 V, and clamps transients at 48.4 V, making it an effective safeguard for power supply circuits and sensitive semiconductors. Designed to operate reliably across a broad temperature range from -55°C to 150°C, it ensures stable performance under demanding environmental conditions.

Key electrical parameters include a test current (It) of 1 mA and a maximum peak pulse current (Ippm) of 8.3 A. The device offers enhanced protection with ESD (Electrostatic Discharge) capability and complies with automotive standard AEC-Q101, reflecting high product quality for use in automotive industry applications. Its compact footprint (4.5 mm length, 2.79 mm width, and 2.09 mm height) allows for efficient use of PCB real estate.
