STTH3R04U STMicroelectronics

STTH3R04 Ultrafast recovery diode Features A K Negligible switching losses Low forward and reverse recovery times High junction temperature DO-15 DO-201AD STTH3R04Q STTH3R04 Description Band indicates cathode side. The STTH3R04 series uses ST s new 400 V planar Pt doping technology. The STTH3R04 is specially suited for switching mode base drive and transistor circuits. SMC SMB Packaged in axial and surface mount packages, STTH3R04S STTH3R04U this device is intended for use in low voltage, high frequency inverters, free wheeling and polarity Table 1.
