They demonstrate low break over current at break over voltage as they withstand peak pulse current, The breakover symmetry is within three volts(DB6). These diacs are intended for use in thyrisitors phase control,circuits for lamp dimming,universal motor speed control,and heat control. Parameters See FIG.3 2.0 -40--- +125 C=22nf(NOTE 2) See FIG.1 ELECTRICAL CHARACTERISTICS Test Conditions -40--- +125 DB3M DB4M See FIG.2 Max Min Dimensions in millimeters www.shunyegroup.com.cn |
