Bourns P4SMA-Q Transient Voltage Suppressor Diodes

Bourns P4SMA-Q Transient Voltage Suppressor (TVS) Diodes meet the challenges of the semiconductor industry to develop increasingly smaller electronic components. These devices offer a 5.8V to 214V working voltage, 6.8V to 250V breakdown voltage, 400W power dissipation, and bidirectional or unidirectional polarity. Bourns P4SMA-Q TVS Diodes conform to JEDEC standards. The surface-mount diodes protect surge and ESD applications, including telecom, computers, industrial, and consumer electronics.
