Reinforced Isolation provides circuit protection
against electrical shock (Safety Class II)
Circuits for safe protective separation against electri-
cal shock according to safety class II (reinforced iso-
lation):
• For appl. class I - IV at mains voltage ≤ 300 V
• For appl. class I - III at mains voltage ≤ 600 V accord-
ing to DIN EN 60747-5-2(VDE0884)/ DIN EN 60747-
5-5 pending, table 2.
Description
The TCDT1120(G) series consists of a phototransis-
tor optically coupled to a gallium arsenide infrared-
emitting diode in a 6-lead plastic dual inline package.
The elements are mounted on one leadframe using a
coplanar technique, providing a fixed distance
between input and output for highest safety require-
ments.
