FEATURES
1. Low zero-cross voltage (max. 15 V)
type added to lineup. Approximately
1/3 of previous product
Helps reduce device noises even further.
2. Two types available: Random type
and zero-cross type
3. Many package sizes available.
(Wide terminal type with 10.16 mm
pitch between I/O terminals available.)
4. High dielectric strength. (Between
input and output: SOP 3, 750 V; DIP
5,000 V)
5. Handles both 100 and 200 V AC
loads
This relay handles both voltages in a
single product it is not necessary for
users that use both types to manage
separate part numbers.
6. Terminal 5 of the DIP 6-pin type is
completely molded.
TYPICAL APPLICATIONS
1. For triac driver in heater controls of
products such as office equipment,
home appliances, and industrial
machines. (For 100V/200V, 50/60 Hz
lines)
2. Triac driver for SSRs

2. DIP4/6 Type
Note: For space reasons the initial letters “APT” of the product number for the DIP 4-pin type, the letter “A”, which indicates the SMD terminal shape for the DIP 4-pin and
6-pin types, and the package type indications “X” and “Z” have been omitted from the product label. (Example: The label for product number APT1221AZ is 1221.)
3. DIP4/6 Wide Terminal Type
Note: For space reasons the initial letters “APT” of the product number for the DIP 4-pin type, the letter “WA”, which indicates the SMD terminal shape for the DIP 4-pin and
6-pin types, and the package type indications “Y” and “W” have been omitted from the product label. (Example: The label for product number APT1221WAY is 1221.)
