IST 8920 DISCRETE SEMICONDUCTOR TEST SYSTEM WITH CURVE TRACER

IST 8920 Product Family

A Complete and Cost Effective Automated Test Equipment (ATE) System
for Testing of Discrete Semiconductor Components from mW to kW

HIGH POWER SEMICONDUCTOR TESTING

Semiconductors should be tested at its actual operating temperature to uncover problems that only appear when a device is under thermal stress. The IST 8920 features a Constant Temperature source to make it easy to test high power devices at their operating temperatures so that failing devices can be detected early before they become a serious problem.

The 8920 supports high power ON-state parameter testing for Vce(sat), Vds(on), Rds(on), Vsd, Vf, and Vtm at force currents of 400 A, 800 A, 1,600 A, 2,400 A, 3,200 A and 4,800 A.

Force voltages for Off-state parameter testing of Breakdown Voltage and Leakage Current measurements can be set to 2.5 KV, 5 KV, 7.5 KV or 10 KV.

KELVIN TEST SOCKET FOR HIGH POWER TESTING

When testing with a Kelvin test socket mounted directly onto the 8920’s high power test head, testing can be performed with currents up to 350 A or voltages up to 5 KV.
Device Packages: TO-220, TO-264, TO-247, 247PLUS, TO-247HV, & ISOPLUSi5-Pak

KELVIN TEST FIXTURES FOR HIGH POWER TESTING

The IST 8920 includes specialized test fixtures that make it easy to setup and measure high power devices such as IGBTs, MOSFETs, Transistors, GTOs, SCRs, and Diodes. The test fixtures provide error-free testing while eliminating tedious and time consuming setups needed to secure test leads and sources to a DUT. Using the test fixtures, testing can be performed at currents up to 4800 A and at voltages up to 10 KV.

SAFETY FEATURES FOR HIGH POWER TESTING

Numerous safety features were designed into the IST 8920 to prevent harm to the DUT, the tester, and the user operating it. Before each test, a safety check is performed to prevent testing on defective, incorrect device types, or pin-outs before power is applied.

During high power testing, a beeper alarm and a high voltage warning light will turn on to warn the user that high voltage is being applied. If an over-current or short circuit condition is sensed or if the DUT’s self break-over or second breakdown condition is reached the tester will shut down as a safety precaution.

The 8920 includes a “Safety Start” feature that protects the user from accidentally starting a test while still handling the device to be tested. When the Safety Start mode is enabled, the user must press a safety button and the Start Test button at the same time in order to run a test.
