Product details
Overview
TLP240A(TP1,F) from Toshiba Electronic Devices & Storage Corporation is a halogen-free, normally-open photorelay IC consisting of an infrared LED optically coupled to a photo MOSFET. It delivers 5000 Vrms isolation, 60 V OFF-state voltage, ≤2 Ω ON-state resistance, and supports up to 500 mA load current - enabling solid-state replacement of mechanical relays in smart metering and factory automation interfaces.
For engineers reviewing the TLP240A(TP1,F) datasheet, TLP240A(TP1,F) pinout, TLP240A(TP1,F) application, or TLP240A(TP1,F) equivalent, key selection criteria include reinforced insulation compliance (UL 1577/508, VDE EN 60747-5-5), through-hole DIP-4 packaging, 3 mA max trigger LED current, and thermal derating behavior across -40°C to +85°C operating range.
Technical Context
The TLP240A(TP1,F) implements optical coupling between GaAs LED and dual-drain photo MOSFET, with pins 1–2 electrically shorted as input terminals and pins 3–4 shorted as output terminals - forming a single-pole, normally-open (1-Form-A) solid-state switch. Its internal structure eliminates mechanical wear and contact bounce.
It meets reinforced insulation requirements per UL 1577 (5000 Vrms, 60 s), UL 508 (for industrial control), and VDE EN 60747-5-5 when ordered with Option (D4). Creepage/clearance distances are 7.0 mm (TLP240A variant), supporting IEC 61800-5-1 and IEC 62109 safety architectures.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms (min) - enables reinforced insulation for mains-connected smart meters and FA controllers |
| OFF-State Output Voltage | 60 V (min) - supports switching of 24–48 V DC control circuits without arcing risk |
| ON-State Resistance | 2 Ω (max) - limits conduction loss to ≤500 mW at 500 mA, reducing thermal stress in compact layouts |
| Trigger LED Current | 3 mA (max) - allows direct drive from low-power MCU GPIOs without external amplification |
| ON-State Current | 500 mA (max) - sustains continuous load switching for solenoids, indicators, and small actuators |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP240AF(TP4,F) | 10.16-mm pitch DIP package; 8.0 mm creepage/clearance; same electrical specs | Better suited for higher pollution degree (PD3) environments per IEC 60664-1 | Select when board layout requires wider spacing or compliance with PD3-rated enclosures |
| PS8501-AX | SOIC-4 package; 3750 Vrms isolation; 400 mA max load; 3.5 Ω RON (max) | Surface-mount alternative with lower profile but reduced isolation and current rating | Choose for space-constrained designs where 5000 Vrms is not mandatory and 400 mA suffices |
Compared with TLP240A(TP1,F), the TLP240AF(TP4,F) offers enhanced creepage for harsher environments, while the PS8501-AX trades isolation and current capacity for SMT compatibility - making TLP240A(TP1,F) optimal for through-hole, high-reliability, mains-isolated applications.

FAQ
What is the isolation voltage rating of the TLP240A(TP1,F)?
The TLP240A(TP1,F) has a minimum isolation voltage rating of 5000 Vrms (AC, 60 seconds) per UL 1577 and VDE EN 60747-5-5 standards. This reinforced insulation rating is validated with 7.0 mm creepage and clearance distances, making it suitable for applications requiring basic and reinforced insulation per IEC 61800-5-1 and IEC 62109.
Can the TLP240A(TP1,F) directly interface with a 3.3 V microcontroller?
Yes - the TLP240A(TP1,F) requires ≤3 mA LED forward current to trigger, allowing direct connection to 3.3 V GPIOs using a ~1 kΩ series resistor. Its low IF threshold eliminates the need for buffer transistors or level shifters, simplifying interface design while maintaining noise immunity via optical isolation.
What is the maximum continuous load current supported by the TLP240A(TP1,F)?
The TLP240A(TP1,F) supports a maximum continuous ON-state current of 500 mA at Ta ≤ 65°C. Derating applies above this temperature: -5 mA/°C up to 85°C ambient. At 85°C, the usable current drops to ~325 mA per UL 508-recommended conditions, ensuring safe operation within thermal limits.
Does the TLP240A(TP1,F) meet RoHS and halogen-free requirements?
Yes - the TLP240A(TP1,F) uses halogen-free resin packaging compliant with IEC 61249-2-21: Br/Cl ≤ 0.09 wt%, total halogens ≤ 0.15 wt%. It is RoHS-compatible (Directive 2011/65/EU), as confirmed by Toshiba's environmental documentation and marked with "F" suffix denoting RoHS compliance in the ordering code.
How does the pin configuration of the TLP240A(TP1,F) differ from standard 4-pin optocouplers?
Unlike conventional optocouplers, the TLP240A(TP1,F) is a two-terminal device: pins 1 and 2 are internally shorted as the LED anode/cathode pair, and pins 3 and 4 are shorted as the MOSFET drain terminals. This configuration enables symmetrical PCB layout and current sharing while preserving the DIP-4 footprint.
