Key Features
- 2500 V isolation voltage for robust galvanic separation between input and output circuits
- TTL-compatible input with 25 mA max forward current at 1.85 V for direct logic-level drive
- 8-pin DIP through-hole package with UL recognition enabling compliant industrial and consumer designs
Applications
TLP559(IGM,F) is used in industrial control systems to isolate microcontroller logic from high-voltage switching loads such as relays and motor drivers. Its TTL-compatible input allows direct connection to 5 V logic without additional drive circuitry. The 2500 V isolation rating also makes it suitable for power supply feedback paths and safety-critical equipment requiring galvanic isolation.

Frequently Asked Questions
What isolation voltage does TLP559(IGM,F) provide, and how does this compare to basic optocouplers?
TLP559(IGM,F) is rated at 2500 V isolation voltage (Vrms), which exceeds the 1000 V to 1500 V rating of many basic optocouplers. This level of isolation is required for power line interfaces, motor drives, and medical equipment where high-voltage transients must be blocked to protect downstream logic circuits.
How should the LED input of TLP559(IGM,F) be driven from a 3.3 V or 5 V MCU GPIO?
The TLP559(IGM,F) LED input has a maximum forward voltage of 1.85 V and a maximum forward current of 25 mA. From a 5 V GPIO, a series resistor of approximately 160 ohm limits current to a safe 20 mA; from a 3.3 V GPIO, a 75 ohm resistor achieves roughly 19 mA, well within the rated limit.
Is TLP559(IGM,F) suitable for high-density SMT board layouts, or does the DIP package limit placement options?
TLP559(IGM,F) uses an 8-pin DIP through-hole package with 2.54 mm lead pitch, which occupies more PCB area than SO-8 or SOP-4 SMT alternatives. For space-constrained SMT designs, Toshiba offers SMT-packaged optocouplers in the TLP family; however, the DIP format is preferred where socketing, field replacement, or hand soldering is needed in low-volume industrial builds.
