Description
• Low-Leakage
The MB family of bridge rectifiers is a 0.5 A rectifier family that achieves high surge current absorption within a
• Surge Overload Rating: 35 A peak
very small foot print. Within its small 35 mm2 form factor,
the MB family shines in its surge capability. In order to
absorb high surge currents, the design supports a 35 A
• Ideal for Printed Circuit Board
• UL Certified: UL #E258596

SOIC-4
IFSM rating and a 5.0 A2Sec I2T rating. Devices in the
family are also rated to breakdown voltages of up to
1000 V. These features make the MB family ideal for
small power supplies that need a little extra surge capability.
For higher IFAV current ratings, lower profile packaging,
or lower VF values, explore the ON Semiconductor
MDB family of bridge rectifiers. For improved VF and
efficiency values in the MB package or even higher
surge capability, ask about ON Semiconductor’s
pending MBxSV family.

Stresses exceeding the absolute maximum ratings may damage the device. The device may not function or be operable above the recommended operating conditions and stressing the parts to these levels is not recommended. In addition, extended exposure to stresses above the recommended operating conditions may affect device reliability. The
absolute maximum ratings are stress ratings only. Values are at TA = 25°C unless otherwise noted.
