Optical isolation The W suffix denotes parameters tested to Teledyne specifications. Low profile hermetic package ELECTRICAL SPECIFICATIONS Built and tested to the requirements of MIL-PRF-28750 (-55C TO +105C UNLESS OTHERWISE NOTED) INPUT (CONTROL) SPECIFICATION DESCRIPTION When used in 2 terminal configuration The Series KD and LD solid-state relays (TTL or direct control) (See Fig. 1) Min Typ Max Units are screened utilizing MIL-PRF-28750 test methods and are packaged in low Input Current V = 5 Vdc (See Fig. 2) 15 mAdc BIAS profile hermetically sealed cases. These relays are constructed with state-of-the- Turn-Off Voltage (Guaranteed Off) 1.5 Vdc art solid state techniques and feature fully floating power FET output Turn-On Voltage (Guaranteed On) 3.8 Vdc technology. This allows the load to be connected to either output terminal and Reverse Voltage Protection -32 Vdc provides a low ON resistance. The input (control) and output are optically isolated Input Supply Range (See Note 1) 3.8 32 Vdc to protect input logic circuits from output INPUT (CONTROL) SPECIFICATION transients. Available options include When used in 3 terminal configuration short circuit and current overload protection, which provides complete (CMOS or open collector TTL) (See Fig. 1) Min Typ Max Units protection for both the relay and system Control Current wiring. This feature not only provides V = 5 Vdc 250 Adc CONTROL protection should a short or overload V = 18 Vdc 1 mAdc occur while the relay is on, but will also CONTROL provide protection should the relay be Control Voltage Range 0 18 Vdc switched into a short. The second option is a status output line. Switch status Bias Supply Voltage (See Note 1) 3.8 32 Vdc returns the true status of the output switch and is optically isolated from the Bias Supply Current 16 mAdc load. It provides status indication independent of the control circuit of the Turn-Off Voltage (Guaranteed Off) 3.2 Vdc relay. The status line provides a logic 0 (low) when the relay output is off with Turn-On Voltage (Guaranteed On) 0.3 Vdc load voltage and continuity present, and a logic 1 (high) when the output is on. 20 18 TELEDYNE RELAYS (800) 284-7007 www.teledynerelays.com KD/LD 1 KD/LD 0 120 18 Q1Series KD/LD OUTPUT (LOAD) SPECIFICATIONS BLOCK DIAGRAM (See Note 2) Min Typ Max Units Continuous Load Current (See Fig. 3) KD and LD series without heat sink 5 Adc LD series with heat sink 10 Adc Leakage Current V =60Vdc LOAD KD00CK, KD20CK 100 A LD00CM, LD20CM 100 A KD02CK, KD22CK 2 mA LD02CM, LD22CM 2 mA Output Voltage Drop KD00CK, KD02CK .60 Vdc KD20CK, KD22CK .70 Vdc LD00CM, LD02CM 10A 1.2 Vdc LD20CM, LD22CM 10A 1.4 Vdc Continuous Operating Load Voltage 60 Vdc Transient Blocking Voltage 25C80 Vdc ON Resistance, I = 100 mA, T = 25C, (See Note 3) NO STATUS LOAD J KD00CK, KD02CK .075 Ohm LD00CM, LD20CM .075 Ohm MECHANICAL SPECIFICATION KD20CK, KD22CK .100 Ohm LD20CM, LD22CM .100 Ohm Turn-On Time (See Fig. 5) 5 ms Turn-Off Time (See Fig. 5) 2 ms Electrical System Spike 25C 600 Vpk Output Capacitance at 25 Vdc, 100 KHz 1600 pF Isolation (Input to Output) KD00CK, KD20CK 10 pF LD00CM, LD20CM 10 pF KD02CK, KD22CK 15 pF LD02CM, LD22CM 15 pF Dielectric Strength 1000 Vac 9 Insulation Resistance 500 Vdc 10 Ohms Output Junction Temperature 130 C I = I LOAD max rated Maximum Junction Temperature 150 C Thermal Resistance Junction to Ambient ( )30 C/W JA Thermal Resistance Junction to Case ()7 C/W JC KD/LD 2 SPECIFICATIONS ARE SUBJECT TO CHANGE WITHOUT NOTICE 20 18 TELEDYNE RELAYS KD/LD 0 120 18 Q1
