Product details
Overview
TLP240GA(LF1,F) from Toshiba Electronic Devices & Storage Corporation is a halogen-free, normally-open photorelay IC comprising an infrared LED optically coupled to a photo MOSFET. It delivers 400 V (min) OFF-state voltage, 120 mA (max) ON-state current, and 5000 Vrms isolation in a 4-pin DIP package - enabling solid-state replacement of mechanical relays in metering and factory automation systems.
For engineers reviewing the TLP240GA(LF1,F) datasheet, TLP240GA(LF1,F) pinout, TLP240GA(LF1,F) application, or TLP240GA(LF1,F) equivalent, this device is selected for high-voltage AC/DC load switching where reinforced insulation, low trigger current (≤3 mA), and creepage ≥7.0 mm are required in safety-critical embedded control interfaces.
Technical Context
The TLP240GA(LF1,F) implements optical coupling between GaAs LED and dual-drain Si MOSFET output stage, with internal shorting of pins 1–2 (LED anode/cathode) and pins 3–4 (MOSFET drains). Its design supports zero-crossing–agnostic switching and operates with input forward voltage of 1.1–1.4 V at 10 mA.
It meets UL 1577, UL 508, CSA C22.2 No. 5A, GB4943.1, and EN 60747-5-5 (when specified with Option D4), with minimum creepage/clearance of 7.0 mm and 0.4 mm internal insulation thickness - confirming suitability for reinforced insulation per IEC 60664-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |

| Trigger LED Current | 3 mA (max) - compatible with low-power MCU GPIOs without buffer stages |
| ON-Resistance | 35 Ω (max, continuous) - limits power dissipation to ≤500 mW at 120 mA, enabling compact PCB layout |
| Turn-On/Off Time | 2 ms / 1 ms (max) - suitable for non-critical timing applications like status indication and sequencing |
| Package | 4-pin DIP (TOSHIBA 11-5B2S) - through-hole mounting with 7.62 mm lead pitch for industrial board reliability |
Pinout & Package
Package: 4-pin DIP (TOSHIBA 11-5B2S), through-hole, 7.62 mm pitch, halogen-free resin body, weight 0.26 g (typ.). Pins 1–2 form the LED input pair; pins 3–4 are internally shorted drain terminals of the output MOSFET.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode - connects to MCU GPIO or driver IC output via current-limiting resistor |
| 2 | Cathode | LED cathode - referenced to system ground; defines LED forward bias direction |
| 3 | Drain | MOSFET drain terminal - electrically tied to pin 4; connects to switched load side |
| 4 | Drain | MOSFET drain terminal - internally shorted to pin 3; provides dual-terminal output routing flexibility |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP240GAF | 8.0 mm creepage/clearance, 10.16 mm pitch DIP package, same electrical specs | Required where higher creepage (>7.0 mm) is mandated by regional safety standards (e.g., EN 61000-4-5 surge zones) | Select TLP240GAF when board layout permits wider lead spacing and enhanced insulation is prioritized over footprint density |
| PVG612AR | 1500 Vrms isolation, 60 V OFF-state, 2 A load current, SOP-4 package | Targets high-current DC loads (e.g., battery disconnect), not AC mains switching | Choose PVG612AR only for low-voltage, high-current DC applications - not a functional substitute for TLP240GA(LF1,F)'s 400 V AC capability |
Compared with TLP240GAF, the TLP240GA(LF1,F) offers tighter 7.62 mm pitch for space-constrained meter PCBs while retaining identical 400 V blocking and 5000 Vrms isolation; versus PVG612AR, it trades higher current capacity for superior AC voltage handling and reinforced insulation certification.

FAQ
What is the maximum continuous ON-state current rating for the TLP240GA(LF1,F)?
The TLP240GA(LF1,F) has a maximum continuous ON-state current rating of 120 mA, validated under derated conditions up to 85 °C ambient temperature. This value is specified in the Absolute Maximum Ratings table and confirmed in Recommended Operating Conditions (UL 508) with thermal derating of −1.2 mA/°C above 25 °C. Exceeding this limit risks irreversible MOSFET degradation.
Does the TLP240GA(LF1,F) support direct drive from a 3.3 V microcontroller GPIO?
Yes, the TLP240GA(LF1,F) supports direct drive from a 3.3 V microcontroller GPIO. Its maximum trigger LED current is 3 mA, and typical forward voltage is 1.27 V at 10 mA - meaning a 220 Ω series resistor limits current to ~9.5 mA at 3.3 V, well within safe operating range. The device remains fully functional even at IF = 0.6 mA (typical trigger point).
What safety certifications apply to the TLP240GA(LF1,F) out-of-the-box?
The TLP240GA(LF1,F) carries UL 1577 (File E67349) and UL 508 (File E499232) recognition, plus CSA Component Acceptance (C22.2 No. 5A, File E67349) and CQC approval to GB4943.1/GB8898. VDE EN 60747-5-5 certification requires specifying Option D4 (e.g., TLP240GA(D4TP1,F)); the base TLP240GA(LF1,F) does not include VDE approval.
How does the pin configuration of the TLP240GA(LF1,F) differ from standard 4-pin optocouplers?
Unlike standard transistor-output optocouplers, the TLP240GA(LF1,F) uses a dual-drain MOSFET output: pins 3 and 4 are internally shorted drain terminals, while pins 1 and 2 are the LED anode and cathode. This 1-Form-A configuration eliminates need for external load referencing and simplifies PCB routing for single-pole switching applications.
Is the TLP240GA(LF1,F) halogen-free, and what does that mean for compliance?
Yes, the TLP240GA(LF1,F) is halogen-free per Toshiba's definition: encapsulant bromine and chlorine each ≤0.09 wt%, aggregate ≤0.15 wt%. This satisfies JPCA-ES-01 and IEC 61249-2-21, supporting RoHS-compliant manufacturing and reducing toxic fume generation during PCB rework or end-of-life incineration.
