Publication date: April 2004 SKH00107BED
MA4X746 (MA746)

Silicon epitaxial planar type

For super high speed switching
For small current rectification
■Features
•Two isolated elements are contained in one package, allowing
high-density mounting
•Forward current (Average) IF(AV) = 200 mA and Reverse voltage
VR < 50 V are achieved
•Optimum for high frequency rectification because of its short
reverse recovery time trr
•Low forward voltage VF and good rectification efficiency
■Absolute Maximum Ratings Ta = 25°C
