D32BULK

Overview

The D32BULK is a bidirectional trigger diode (DIAC) manufactured by EIC Semiconductor Inc. It features an axial package and operates within a breakover voltage range of 27 to 37 volts. The component supports a breakover current of 100 microamperes and delivers a peak output current of 2 amperes. It is designed for reliable performance across an operating temperature range of -40°C to 100°C junction temperature. This device serves as a symmetric triggering element for controlling AC power applications.

Feature Summary

• Bidirectional symmetrical triggering capability for AC circuits
• Axial leaded package construction for through-hole mounting
• Defined breakover voltage window for consistent gate triggering

Applications

• Triac gate triggering in light dimmer circuits
• Motor speed control systems
• Thermostat switching applications

Procurement Notes

Verify the specific manufacturer part number against official EIC Semiconductor documentation to ensure authenticity. Confirm that the received components match the specified axial package type and electrical characteristics. Check for RoHS compliance status if required by your assembly standards. Ensure storage conditions maintain component integrity prior to soldering.

Selection Notes

Select this component when a precise breakover voltage between 27 and 37 volts is required for triac activation. Consider the 2A peak current rating for load compatibility. The axial package suits standard PCB layouts requiring through-hole integration. Evaluate thermal management needs given the -40°C to 100°C operational range.

Part Context

This DIAC belongs to the family of bidirectional trigger diodes used primarily for initiating conduction in thyristor-based circuits. It functions similarly to other DIACs but offers specific voltage thresholds suitable for standard mains frequency applications. The axial form factor distinguishes it from surface-mount alternatives, catering to traditional electronic assembly methods.
