Bourns offers Schottky Rectifier Diodes for rectification applications, in compact chip package DO-214AA (SMB) size format, which offer PCB real estate savings and are considerably smaller than competitive parts. The Schottky Rectifier Diodes offer a forward current of 2 A with a choice of repetitive peak reverse voltage of 20 V up to 60 V. Bourns[®] Chip Diodes conform to JEDEC standards, are easy to handle with standard pick and place equipment and the flat configuration minimizes roll away. ## ~~**Electrical Characteristics (@ TA = 25 °C Unless Otherwise Noted)**~~ |**Parameter**|**Symbol**|**CD214B-**|**CD214B-**|**CD214B-**|**CD214B-**|**CD214B-**|**Unit**| |---|---|---|---|---|---|---|---| |||**B220**|**B230**|**B240**|**B250**|**B260**|| |Forward Voltage (Max.)
