Brief Description of DB3

DB3 is a part number for a three-layer, two-terminal, bidirectional trigger diode. It is commonly used in electronic circuits as a triggering element for thyristors and triacs.

The DB3 diode has a breakover voltage of around 30V, which means that it conducts current only when the voltage across it exceeds this value. Once the breakover voltage is reached, the DB3 diode switches on and conducts current until the current drops below a certain threshold.

The DB3 diode is often used in circuits that require a simple and reliable way to trigger thyristors and triacs. For example, it can be used in light dimmer circuits or in motor control circuits.

The DB3 diode is housed in a DO-35 package, which is a small and compact package that is commonly used for small-signal diodes. This package allows for easy mounting on printed circuit boards and provides a secure connection to the circuit.

Equivalent for DB3

DB3 is a three-layer, two-junction diode known as a DIAC (diode for alternating current). It is commonly used in triggering and control circuits for thyristors and triacs, among other applications. It has a breakdown voltage range of 28-32V.

If you are looking for a replacement for the DB3 diode, there are several other DIACs that you could consider, depending on your specific requirements. Some possible replacements include the following:

DB4: The DB4 is a DIAC with a breakdown voltage range of 30-36V. It has a slightly higher voltage rating than the DB3, but is otherwise similar in its characteristics.

DB6: The DB6 is a DIAC with a breakdown voltage range of 60-70V. It has a much higher voltage rating than the DB3, and is suitable for use in higher voltage applications.

ST2: The ST2 is a DIAC with a breakdown voltage range of 28-32V, identical to that of the DB3. It is a direct replacement for the DB3, with similar characteristics and performance.

Q4004L4: The Q4004L4 is a DIAC with a breakdown voltage range of 28-36V. It has a slightly higher maximum breakdown voltage than the DB3, but is otherwise similar in its characteristics.
