Monolithic Eight-Diode Array
Exceptional Efficiency
Low Forward Voltage
Fast Recovery Time
High Peak Current
Small Size
DESCRIPTION
This eight-diode array is designed for high-current, low duty-cycle applications
typical of flyback voltage clamping for inductive loads. The dual bridge connection
makes this device particularly applicable to bipolar driven stepper motors.
The use of Schottky diode technology features high efficiency through lowered for-
ward voltage drop and decreased reverse recovery time.
This single monolithic chip is fabricated in both hermetic CERDIP and copper-
leaded plastic packages. The UC1610 in ceramic is designed for -55擄C to +125擄C
environments but with reduced peak current capability. The UC2610 in plastic and
ceramic is designed for -25擄C to +125擄C environments also with reduced peak
current capability; while the UC3610 in plastic has higher current rating over a 0擄C
to +70擄C temperature range.
