SILICON BIDIRECTIONAL DIACS

The glass passivated, three-layer, two terminal, axial lead,

hermetically sealed diacs are designed specifically for

triggering thyristors. They demonstrate low breakover current

at breakover voltage as they withstand peak pulse current.

The breakover symmetry is within four volts with a typical

breakover voltage of DB-3 32 V, DB-4 40 V. These diacs are

intended for use in thyristor phase control, circuits for

lamp-dimming, universal-motor speed controls, and heat

controls.

Storage Temperature Range TS - 40 OC to +150 OC

Operating Temperature Range TJ - 40OC to +100 OC

MAXIMUM RATINGS at 50 OC Ambient

Peak Current (10 µs duration, 120 cycle repetition rate) IP ± 2 A Max.

Peak output voltage eP 3 ± Volts Max.
