KTLP3616 (3506) Series

8PIN RANDOM-PHASE TRIAC DRIVER

cosmo PHOTOCOUPLER

z Description z Schematic
The KTLP3616 series consist of a GaAs infrared
emitting diode optically coupled to an 1 8
non-zero-crossing silicon bilateral TRIAC and a main 2
output power TRIAC. These devices isolate low
3 6
voltage logic from 115/240 VAC lines to provide
4 5
random phase control of high current TRIACs or
thyristors. These devices feature greatly enhanced
static dv/dt capability to ensure stable switching 1. Cathode 5. Gate

4. Cathode

z Features
1. Pb free and RoHS compliant
2. 600V peak blocking voltage
3. On-state R.M.S Current 1.2A
4. Simplifies logic control of 115/240 VAC power
5. Non zero voltage crossing
6. Isolation voltage between input and output (Viso：5300Vms)
7. MSL class 1
8. Agency Approvals：
• UL Approved (No. E169586): UL1577
• c-UL Approved (No. E169586)
• VDE Approved (No. 40020973): DIN EN60747-5-5

z Applications
• TRIAC driver
• Programmable controllers
• AC-output module
• Solid state relay
• Isolated interface between high voltage AC devices and
lower voltage DC control circuitry
• Switching motors, fans, heaters, solenoids and valves.
• Phase or power control in applications, such as lighting and
temperature control equipment
