Thyristor Product Catalog
General Notes
Lead solder temperature is +230 °C for 10-second maximum;
≥
1/16" (1.59 mm) from case.
See “Package Dimensions” section of this catalog.
Electrical Specification Notes
(1)
Breakover voltage symmetry as close as 1 V is available from the
factory on these products.
(2)
(3)
See Figure E8.4 and Figure E8.5 for test circuit and waveforms.
Typical switching time is 900 nano-seconds measured at I
PK
(Figure E8.4) across a 20
resistor (Figure E8.5). Switching time
is defined as rise time of I
PK
between the 10% to 90% points.
See V-I Characteristics.
