ARMY TM 9-1290-365-24&P 1.5.7 Types of ESD Sensitive Devices. ESD sensitive devices and information pertaining to susceptibility are listed in Table 1-3. Table 1-3. Device Type an Range of ESD Susceptibility (Volts) Device Type Range of Susceptibility (Volts) VMOS 30 to 1800 MOSFET 100 to 200 GaAsFET 100 to 300 EPROM 100 JFET 140 to 7000 SAW 150 to 500 OP AMP 190 to 2500 CMOS 250 to 3000 Schottky Diodes 300 to 2500 Film Resistors 300 to 3000 Bipolar Transistors 380 to 7000 ECL (PC Board Level) 500 to 1500 SCR 680 to 1000 Schottky TTL 1000 to 2500 1.5.8 Army Adopted Configuration. In general, a protective workstation must occupy a 10-foot (3-meter) square area and be cordoned off with yellow lines or other means of segregation. The area should be posted with signs identifying it as a static-free work area. This protective station may be used for packaging or by maintenance personnel for repairing sensitive devices, but not when applying power to the instrument for testing. 1.5.9 Precautions within 20-foot (6-meter) Distance. For purposes of initially established work-sites, the major controlled area shall be considered as that area within a 20-foot (6-meter) radius of the bench(es). Within this controlled area, the following should be excluded: a. Materials handling trucks, carts, and equipment. b. Conveyor drive mechanisms and moving belts. c. Sandblast and air-cleaning equipment. d. Paint spray booths and ventilating equipment. e. Storage of bulk common plastic materials such as large rolls of cushion wrapping material, loose fills, slab cushioning, or fastpacks. 1.5.10 Precautions within 50-foot (15-meter) Distance. A special hazard exists in areas where stretch and shrink wrapping operations are performed. This is also true where skin packaging, foam-in-place. and plastic bagging are conducted. These types of functions must be kept at least 50 feet (15 meters) away from static-protected worksites. 1-6
