TSZ12J48SR

The TSZ12J48SR is a kind of solid state AC relay. It is designed for computer peripherals, machine tool controls, process control systems and traffic control systems. There are some features as follows: (1)RMS on-state current: IT(RMS)=12 A; (2)non-repetitive peak off-state voltage: VDSM: 600 V; (3)TTL compatible; (4)isolation voltage (t=1 min): 3750 V AC (input to output) and 1500 V AC (input/output to base).

What comes next is the maximum ratings of TSZ12J48SR (Ta=25): First is about the input (control) section: (1)control input voltage (DC), VF(IN): 5.5 V; (2)control input current (DC), IF(IN): 30 mA. Then is about the output (load) section: (1)non-repetitive peak off-state voltage, VDSM: 600 V; (2)nominal AC line voltage, VAC: 240 V; (3)RMS on-state current, IT(RMS): 12 A; (4)peak one cycle surge on-state current (non-repetitive), ITSM: 120 A (50 Hz) and 132 A (60 Hz); (5)operating frequency range, f: 45-65 Hz; (6)isolation voltage (t=1 min), BVS/AC: 3750 V AC (input to output) and 1500 V AC (input/output to base); (7)operating temperature range, Topr: -20 to 80; (8)storage temperature range, Tstg: -30 to 80.

The following is the electrical characteristics of TSZ12J48SR (Ta=25): First is about the input (control) section: (1)pick up voltage, VFT: 4.0 V max when VAC=100 Vrms, resistive load; (2)drop out voltage, VFD: 0.5 V min when VAC=100 Vrms, resistive load; (3)input resistance, R(IN): 160 typ. Then is about the output (load) section: (1)off-state leakage current, IOL: 6.0 mA max at VAC=200 Vrms, f=50 Hz; (2)peak on-state voltage, VTM: 1.5 V max when IT(RMS)=12 A; (3)dv/dt (off-state), dv/dt: 50 V/s min at VDSM=0.7*rated.
