Thyristors

pdf icon Fundamental Characteristics of Thyristors Application Note

The thyristor family of semiconductors consists of several very useful devices. The most widely used of this family are silicon controlled rectifiers (SCRs), triacs, sidacs, and diacs. In many applications these devices perform key functions and are real assets in meeting environmental, speed, and reliability specifications which their electro-mechanical counterparts cannot fulfill. This application note presents the basic fundamentals of SCR, triac, sidac, and diac thyristors so the user understands how they differ in characteristics and parameters from their electromechanical counterparts. Also, thyristor terminology is defined.

pdf icon Mounting and Handling of Semiconductor Devices Application Note

Proper mounting and handling of semiconductor devices, particularly those used in power applications, is an important, yet sometimes overlooked, consideration in the assembly of electronic systems. Power devices need adequate heat dissipation to increase operating life and reliability and allow the device to operate within manufacturers' specifications. Also, in order to avoid damage to the semiconductor chip or internal assembly, the devices should not be abused during assembly. Very often, device failures can be attributed directly to a heat sinking or assembly damage problem. The information in this application note guides the semiconductor user in the proper use of Teccor devices, particularly the popular and versatile TO-220 and TO-202 epoxy packages.

pdf icon Surface Mount Soldering Recommendations Application Note

The most important consideration in reliability is achieving a good solder bond between surface mount device (SMD) and substrate since the solder provides the thermal path from the chip. A good bond is less subject to thermal fatiguing and will result in improved device reliability. This application note discusses the different soldering methods for Littelfuse's Teccor brand thyristor products.

AN1006 Testing Teccor Semiconductor Devices Using Curve Tracers

One of the most useful and versatile instruments for testing semiconductor devices is the curve tracer (CT). Although widely used by semiconductor manufacturers for design and analytical work, the device consumer will find many uses for the curve tracer, such as incoming quality control, failure analysis, and supplier comparison. Curve tracers may be easily adapted for go-no go production testing. This application note describes how to use curve tracers.
