Product Overview
This is a light cream-colored 6-pin DIP body with the printing in a gold-colored ink: a Motorola M logo at the top, then MOC over 3023, then a date code 9304, with a dot at the pin-1 corner. A bare MOC3023 with that logo is the legacy Motorola DIP part, and the brand on this card is correct as it stands. The MOC302x line couples an infrared LED to a silicon bilateral switch that in turn drives a power triac; 74 pieces are on the shelf, sold each.
Key Features
- Infrared LED coupled to a silicon bilateral switch for driving a power triac, per onsemi's published MOC302xM data
- LED trigger current IFT 5 mA maximum, the figure specific to the 3023; the MOC3022 is 10 mA and the MOC3021 is 15 mA, so the lower number is the more sensitive part, per onsemi
- Random-phase, non-zero-cross driver; zero-crossing belongs to the MOC304x line, not to this one, per onsemi
- VDRM 400 V across the MOC302x group, per onsemi
- Isolation surge voltage 4170 VAC RMS for one minute, per onsemi
- LED forward voltage 1.15 V to 1.50 V at 10 mA, maximum LED current 60 mA, ITSM 1 A at 100 us, per onsemi
- 6-pin DIP, 8.51 mm by 6.35 mm on 2.54 mm lead pitch, per onsemi
- Body marking read from these photos: Motorola M logo, MOC 3023, 9304
Verify against onsemi's published MOC302x data before designing in.
Applications
- Solenoid and valve control from logic-level drive
- Static AC power switches and solid state relays
- Lamp ballast switching
- Interfacing a microprocessor to 115 VAC peripherals
Frequently Asked Questions
How many should I order?
Order one per switched channel and round up if the board has several; 74 are on the shelf here, sold each, so a multi-channel build can come off a single order. Shipping is $8 flat rate and free on orders over $28, so small parts like this ship smartest as part of a larger order.
Will this switch at the AC zero crossing?
No. The MOC3023 is a random-phase driver, so it fires whenever the LED is driven rather than waiting for the line to cross zero. If your design needs zero-cross switching for inrush or EMI reasons, that is the MOC304x line and not this part.
Five milliamps in at the LED, and a triac somewhere downstream does the heavy lifting.
