## Summary description

Diac NTE6408 is a trigger (diac) semiconductor device in a DO-35 package with a maximum forward current (Ifmax) of 2 A and a breakdown voltage range of 28–36 V. RoHS-compliant, it is used to initiate conduction in TRIACs and other AC switching circuits, providing reliable triggering for lighting controls, motor starters, and phase-control dimmers.

## Long description

Diac NTE6408 is a semiconductor trigger diode in a DO-35 glass package designed to provide a well-defined breakover characteristic for AC switching circuits. With a specified breakdown (breakover) voltage range of 28–36 V and a maximum forward current rating of 2 A, this diac is intended to initiate conduction in TRIACs and similar bidirectional devices. The component is RoHS-compliant and suitable for use in circuits that require predictable triggering behavior under alternating current conditions.
Advantages
The device offers a narrow breakover voltage range that ensures repeatable triggering thresholds, improving phase-control accuracy in dimmers and motor controllers. Its DO-35 package provides reliable isolation and straightforward through-hole mounting. The 2 A maximum forward current rating supports brief surge conditions during trigger events while the RoHS compliance ensures the part meets contemporary environmental and regulatory requirements.
Suitable for
Phase-control light dimmers
Motor starter and speed control circuits
AC switching and timing circuits that use TRIACs
Overvoltage or transient trigger applications
Key specifications
Package type: DO-35 glass axial
Breakdown (breakover) voltage: 28–36 V
Maximum forward current (Ifmax): 2 A (pulse/surge conditions)
Bidirectional trigger device suitable for AC operation
Lead configuration: axial leads for through-hole mounting
Compliance: lead-free / RoHS-compatible construction
How to use
Install the diac in the trigger path between the control capacitor and the gate of a TRIAC or equivalent bidirectional switch. Ensure correct orientation of axial leads for secure solder joints and maintain recommended clearances on the PCB for the breakover voltage. In AC phase-control circuits, adjust series resistance and capacitance values to set the RC time constant that determines the firing angle; the diac will conduct once the capacitor voltage reaches the device’s breakover threshold, sending a pulse to the TRIAC gate. Verify that expected surge currents during triggering do not exceed the diac’s maximum forward current rating and provide appropriate snubbing or current-limiting elements where required.
Usage recommendations
For reliable long-term operation, use the diac within its rated voltages and limit repetitive surge currents. When designing dimmers or motor controllers, pair the diac with components rated for the same or higher voltage and provide adequate thermal management and spacing to prevent unintended conduction. Test trigger timing across the intended AC mains range to confirm consistent firing behavior.
