SC245 Datasheet, PDF (4/4 Pages) Digitron Semiconductors – THYRISTOR

NOTES:
1. Characteristic values apply lor eithei polarity of main terminal 2
referenced to main terminal 1.
2. Main terminal 1 is the reference t e r m i n a l for main t e r m i n a l 2 and
gate terminal.
3. With Vrj equal to maximum allowable off-state voltage.
4. The junction-to-ambient value is under worst case conditions; i.e.,
with No. 22 copper wire used for electrical contact to the terminals
and natural convection moling.
5. lunction-lo-case steady-state thermal resistance (Rgjc) is tested in
accordance with F l A - N I - M A Standard RS-.W. Section 3.3.2, which
states: "Thermal charactt'ristivs arc to be measured with the device
uprrariiiR in onlv one Jin'clion." The values listed are the limiting
value for either direction.
6. Apparent thermal resistance applies for a 50 or 60 Hz full sine wave
of current. It can be calculated with the following formula:
Apparent thermal resistance =—Jl.max) ...
