4408-KT

Thermal Resistance Tester               

 

The TESEC Thermal Resistance ΔVGS Tester Model 4408-KT measures thermal resistance for Compound semiconductor(GaN/GaAs FET/HEMT) as ΔVGS resulting from the temperature rise during power forcing, compares ΔVGS with limits, decides the result for binning, and displays VGS1, VGS2 and ΔVGS on the LCD panel.
By inputting a thermal coefficient to the tester, it directly displays the raised temperature of the junction.
The tester is furnished with the functions of the contact check and the oscillation detection to prevent measurement errors caused by contact failures and oscillation for improved testing reliability.
In addition, the tester has a device protection circuit which prevents devices from being damaged at the start of an avalanche.
