SEMICONDUCTOR TESTING

High voltage opto isolators provide high voltage insulation between circuit elements, allowing control signals to be transferred but blocking AC or DC power. Electronic devices and semiconductor ICs used for Insulation are called isolators. This insulation is required to prevent electrical shock to human operators and preventing damage to processors. Some examples of applications that need insulation include industrial automation systems, motor drives, medical equipment, solar inverters, power supplies and electric vehicles. The main categories of insulation are Basic and reinforced insulation. One of the critical parameters that are tested according to standards like IEC 61747-5-5 and IEC 61747-17 is maximum surge isolation voltage (VIOSM). EMC PARTNER provide specialized solutions and accessories to perform insulation tests up to 30kV to improve semiconductor reliability.

EMC TEST SOLUTIONS FOR SEMICONDUCTOR ISOLATORS:

WITH «BASIC INSULATION»

Semiconductors with basic insulation must pass the surge insulation test on component level according to standards IEC 60747-17, IEC 60747-5-5 or similar. Basic Isolator with certain VIOSM as per manufacturer specification are subjected to a surge test at a peak voltage of 1.3 times VIOSM for basic insulation.

WITH «REINFORCED INSULATION»

The same standards IEC 60747-17, IEC 60747-5-5 or similar apply also to semiconductors with reinforced insulation on component level. However reinforced isolators with a certain VIOSM must pass the surge test at a peak voltage of 1.6 times VIOSM. The minimum required test level is 10kV.

ON «SYSTEM LEVEL»

The surge test is also used for compliance to system-level standards, such as the IEC 61800-5-1, IEC 61010-1, IEC 60335-1. Each standard requires a certain level of surge capability for a given system voltage. For example, IEC 61800-5-1 requires for cat. III equipment operating at 1000 Vrms, a minimum surge capability of 8kV for basic and 12kV for reinforced insulation.
