ZD20CF Series 2A, 60 Vdc Optically Isolated Short-Circuit Protected Part Number Description ZD20CF* 2A, 60 Vdc, short-circuit protected up to 33 Vdc, solid-state relay for through-hole mounting SZD20CF* 2A, 60 Vdc, short-circuit protected up to 33 Vdc, solid-state relay for surface mount *W for +25C ambient T for over-temperature screen FEATURES/BENEFITS Short-circuit protected Overload protected ELECTRICAL SPECIFICATIONS 2 Amp load (55C to +105C ambient temperature Low off-state leakage unless otherwise specied) Optical isolation Compact 6-pin package INPUT (CONTROL) SPECIFICATIONS Min Max Units DESCRIPTION Input Current 8 20 mA ZD20CF Series Relays have optical isolation between Input Voltage 10mA 2 3 Vdc relay input and output. Loads may be connected Must Turn-On 8 mA to either the positive or negative output terminals. ZD20CF Relays act as electronic circuit breakers Must Turn-Off Current 100 A that sense shorted loads or other overload events Must Turn-Off Voltage 0.8 Vdc and then trip-off. Relay contacts open and no current Reverse Polarity 6 Vdc ows through the relay and associated loads. These relays prevent overcurrent damage to the system. OUTPUT (LOAD) SPECIFICATIONS Cycling the relay on-off removes the tripped or Min Max Units latched-off condition and returns the relay to the Load Voltage Range 0 60 Vdc normal operating state.
