PU1xMx/PU2xMx FREDs

Taiwan Semiconductor's PU1xMx/PU2xMx families of fast recovery epitaxial diodes (FREDs) offer optimized switching speed vs. reverse recovery time. These high-reliability (AEC-Q101 qualified) devices' soft reverse recovery results in lower noise switching while achieving low losses and increased efficiency. The micro-SMA package heat spreader contacts provide excellent heat transfer.

Features

• Fast switching and reverse recovery times increases efficiency in a wide range of power electronics designs from medium-voltage to high-voltage applications, lowers EMI and RFI, and simplifies snubber and filtering design
• Low reverse leakage: industry-leading maximum I_R (1 µA at T_J = +25°C) improves efficiency and offers a more controlled switching response between forward and reverse conduction modes
• Low reverse recovery charge: maximum Q_RR (40 nC at I_F = 0.5 A, I_R = 1.0 A, I_RR = 0.25 A) lowers parasitic ringing and EMC, reduces the need for snubbers, increases switching speed, and lowers losses
• Automotive qualified available: all parts in the family meet stringent automotive reliability and performance criteria and production part approval process (PPAP) documentation is available
• Global materials compliance: RoHS compliant, halogen-free (per IEC-61249-2-21), WEEE, REACH, California Prop. 65, JESD-201 Class 2 whisker test, and others
• Small surface-mount micro SMA package is ideal for automated placement. Low-profile packaging with heat-spreader contacts provides excellent thermal management
