GENERAL DESCRIPTION
The ND16A60 superdiode is a low-frequency rectifier performing a function analogous to the standard diode. Compared to a standard diode, the superdiode will conduct current with much reduced forward voltage drop. Typical forward voltage drop at 16A current is around 75mV. The standard Schottky diode rated for the same maximum forward current will feature substantially more power dissipation due to higher voltage drop across the device. Current [A]
Forward Voltage [mV]The ND16A60 superdiode is designed to operate without a heat-sink. As is the case with all semiconductor devices, forward current flow causes temperature rise of the device beyond the ambient temperature of the environment. The actual maximum sustainable device current is therefore dependent on the ambient temperature. The temperature rise of 50C corresponds to 16A forward current. Nevertheless, the device can sustain an occasional overcurrent exceeding 20A. Temperature [C]
Forward Current [A]
The forward start-up current of ND16A60 is less than 100mA. The
voltage-current characteristic for very low current exhibits negative
resistance.
Reverse Current [uA]
Reverse Voltage [V]The dynamic response of the ND16A60 is fast-on, slow-off. Switching times are somewhat dependent on the overall circuit impedance. The turn-off time when driven with a 20V peak-to-peak function generator square wave with a 50Ohm port is typically around 5ms. The reverse continuous blocking voltage is at least 60V.

The ND16A60 comes in the DO-247 package. With 14ga leads the package
can sustain a low voltage drop operation even with high current
levels. The package does not have a metal plate which makes it very
suitable for placing in an enclosure, such as a junction box, without
a risk of electrical contact. The package is still suitable for
mounting on a heatsink with the standard hardware, although a heat
sink is not necessary to operate the diode up to 16A forward current.
