Test Method for Thermal Resistance (Impedance).

Test method : Fujipoly test method FTM P-3010 which gives ASTM D5470 equivalent value.
1) Punched-out specimen in TO-3 package is located between a transistor and heat sink (Fig.1). and secured with screws the position (A),using a screwdriver.
2) DC 10V, 2A (20W) current is applied to the transistor.
3) After three minutes, the thermal resistance is calculated based on the following formula (B).
