features l the three layer, two terminal, axial lead, hermetically sealed diacs are designed specifically for triggering thyristors. l they demonstrate low breakover current at breakover voltage as they withstand peak pulse current, the breakover symmetry is within three volts(db3,dc34,DB4) or four volts(db6). l these diacs are intended for use in thyrisitors phase control , circuits for lamp dimming, universal motor speed control ,and heat control. maximum ratings l operating temperature: -40 o c to +11 0 o c l storage temperature: -40 o c to +125 o c electrical characteristics @ 25 o c unless otherwise specified notes:1.electrical characteristics applicable in both forward and reverse directions. 2.connected in parallel with the devices. db3/dc34 and DB4/db6 silicon bidirectional diac power dissipation on printed circuit(l=10mm) p c 150mw t a =50 o c repetitive peak on-state current db3,dc34,DB4 db6 i trm 2.0a 16a t p =10us,f=100hz breakover voltage db3 dc34 DB4 db6 v bo min typ max 28 32 36v 30 34 38v 35 40 45v 56 60 70v c=22nf(note 2) breakover voltage symmetry db3, dc34, DB4 db6 |+v bo | -|-v bo | 3v 4v c=22nf(note 2) output voltage(note 1) v o(min) 5v breakover current(note 1) i bo(max) 100ua c=22nf rise time(note 1) t r 1.5us leakage current(note 1) i b(max) 10ua v b =0.5v bo(max) do-35g inches mm dim min max min max note a --- .150 --- 3.8 b --- .079 --- 2.00 c --- .020 --- .52 d 1.083 --- 27.50 --- a b c d d dimensions
