General Information
Electrical Characteristics (@ TA= 25 °C Unless Otherwise Noted)
Thermal Characteristics (@ TA= 25 °C Unless Otherwise Noted)
Notes:
1 See Forward Derating Curve.
2 Measured @ 1.0 MHz and applied reverse voltage of 4.0 VDC.
3 Thermal resistance from junction to ambient and from junction to lead P.C.B. mounted on 0.2 ˝ x 0.2 ˝ (5.0 mm x 5.0 mm) copper pad areas.
The markets of portable communications, computing and video equipment are challenging the semiconductor industry to develop
increasingly smaller electronic components. Bourns offers Glass Passivated Rectifiers for rectification applications, in compact chip
DO-214AA (SMB) size format, which offer PCB real estate savings and are considerably smaller than most competitive parts. The Glass
Passivated Rectifier Diodes offer a forward current of 2.0 A with a choice of repetitive peak reverse voltage of 50 V up to 1000 V.
Bourns®Chip Diodes conform to JEDEC standards, are easy to handle on standard pick and place equipment and their flat configuration
minimizes roll away.
