Product details
Overview
TLP240D(TP1,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 in a 4-pin DIP through-hole package. It delivers 5000 Vrms isolation, 200 V OFF-state voltage, ≤3 mA trigger LED current, ≤8 Ω ON-state resistance, and supports 250 mA load switching - ideal for replacing mechanical relays in smart metering and factory automation control circuits.
For engineers reviewing the TLP240D(TP1,F) datasheet, TLP240D(TP1,F) pinout, TLP240D(TP1,F) application, or TLP240D(TP1,F) equivalent, key selection criteria include reinforced insulation compliance (UL 1577, UL 508, EN 60747-5-5), thermal derating behavior (ION vs. Ta), and lead-forming/taping configuration (TP1 = tape-and-reel, 1500 pcs).
Technical Context
The TLP240D(TP1,F) implements a single-pole, normally-open (1-Form-A) solid-state switch architecture with optical coupling between input LED and output photo MOSFET. Its internal two-terminal structure shorts pins 1–2 (LED anode/cathode) and pins 3–4 (MOSFET drain–drain), enabling bidirectional AC/DC load switching up to 200 V with galvanic isolation.
It meets reinforced insulation requirements per UL 1577 (5000 Vrms, 1 min), UL 508 (for industrial control), and VDE EN 60747-5-5 when specified with Option D4. The device operates across –40°C to +85°C ambient, with junction temperature limited to 125°C (105°C for UL 508-compliant operation).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms (min) - enables reinforced insulation for safety-critical mains-connected equipment |
| OFF-State Voltage | 200 V (min) - supports switching of 120/230 VAC line-powered loads without external snubbers |
| Trigger LED Current | 3 mA (max) - allows direct drive from low-power microcontrollers without buffer transistors |
| ON-State Resistance | 8 Ω (max) - limits conduction loss to ≤500 mW at 250 mA, reducing thermal stress on PCB |
| Turn-On/Off Time | 1–3 ms / 0.1–1 ms - suitable for slow-cycle industrial sequencing, not high-frequency PWM |
| Creepage/Clearance | 7.0 mm (TLP240D) - satisfies IEC 60664-1 pollution degree 2 requirements for indoor industrial use |
| Operating Temp | –40°C to +85°C - validated for deployment in uncontrolled environments like electricity meter enclosures |
Pinout & Package
Package: 4-pin DIP (through-hole), Toshiba package code 11-5B2S, 7.62-mm lead pitch, weight 0.26 g (typ.).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode - connect to MCU GPIO or driver with current-limiting resistor |
| 2 | Cathode | LED cathode - tie to GND or active-low driver; pins 1 and 2 are internally shorted as a two-terminal LED |
| 3 | Drain | MOSFET drain - connects to one side of AC/DC load; pins 3 and 4 are internally shorted as dual-drain output |
| 4 | Drain | MOSFET drain - redundant terminal for high-current routing or PCB layout symmetry; no separate gate control |
Key Features
| Feature | Design Value |
|---|---|
| Halogen-Free Resin Encapsulation | Meets IEC 61249-2-21; Br/Cl ≤0.09 wt%, total halogens ≤0.15 wt% - supports RoHS-compliant end-product certification |
| Reinforced Insulation Rating | 5000 Vrms isolation with 7.0 mm creepage/clearance - eliminates need for additional barrier spacing in UL/EN-certified designs |
| Low Trigger Threshold | ≤3 mA LED current required - enables direct interface with 3.3 V/5 V logic without level-shifting or amplification |
| Dual-Drain Output Configuration | Pins 3 and 4 internally shorted - simplifies PCB layout for high-current paths and improves thermal current sharing |
| UL 508 Recognition | File No. E499232 - validates use in industrial control panels without additional system-level safety review |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP240DF(TP4,F) | 8.0 mm creepage/clearance; 10.16-mm pitch DIP package; same electrical specs | Required where higher pollution degree (IEC 60664-1 PD3) or wider spacing mandates larger isolation distances | Select TLP240DF(TP4,F) for outdoor or high-humidity industrial enclosures needing enhanced creepage margin |
| PS2561-1-V-D-A | Lower 5000 Vrms isolation but higher 350 mA ION; 4-pin SOIC-4 package; slower tON/tOFF (5/10 ms) | Better suited for space-constrained PCBs where surface-mount is mandatory and timing is non-critical | Choose PS2561-1-V-D-A only if board area is constrained and 250 mA rating is insufficient for the load |
Compared with TLP240D(TP1,F), TLP240DF(TP4,F) provides greater physical isolation margin in identical functional roles, while PS2561-1-V-D-A trades package size and speed for higher current capacity - neither is pin-compatible, requiring layout revision for substitution.

FAQ
What safety certifications does the TLP240D(TP1,F) hold?
The TLP240D(TP1,F) is UL-recognized under UL 1577 (File E67349) and UL 508 (File E499232), cUL-recognized per CSA Component Acceptance Service No.5A (E67349), CQC-approved to GB4943.1/GB8898, and VDE-approved to EN 60747-5-5 and EN 62368-1 when ordered with Option D4. These approvals validate its use in reinforced insulation applications without additional system-level safety analysis.
Can the TLP240D(TP1,F) switch AC loads directly?
Yes, the TLP240D(TP1,F) can switch AC loads directly due to its bidirectional photo MOSFET output structure. Pins 3 and 4 are internally shorted drains, enabling symmetrical conduction across both half-cycles of 120/230 VAC. Its 200 V minimum OFF-state voltage and 8 Ω max RON make it suitable for resistive and lightly inductive AC loads up to 250 mA RMS.
What is the meaning of "(TP1,F)" in the TLP240D(TP1,F) part number?
In TLP240D(TP1,F), "TP1" denotes tape-and-reel packaging (1500 pcs per reel), and "F" indicates RoHS-compliant, halogen-free resin encapsulation. This configuration ensures automated SMT placement compatibility and environmental compliance per EU Directive 2011/65/EU - distinct from magazine-packaged (F) or lead-formed variants.
How does thermal derating affect the TLP240D(TP1,F)'s maximum load current?
The TLP240D(TP1,F)'s maximum ON-state current decreases linearly above 25°C ambient: –2.5 mA/°C per Absolute Maximum Ratings table. At 65°C ambient, rated ION drops to 162.5 mA (250 – 2.5 × 40). Designers must apply this derating curve - shown in Fig. 16.2 of the datasheet - to ensure safe operation under worst-case enclosure temperatures.
Is the TLP240D(TP1,F) compatible with 3.3 V microcontroller GPIOs?
Yes, the TLP240D(TP1,F) is fully compatible with 3.3 V microcontrollers. Its maximum trigger LED current is 3 mA, and typical forward voltage is 1.27 V at 10 mA. A 680 Ω series resistor limits current to ~3.1 mA at 3.3 V, well within specification and eliminating need for external drivers or level shifters.
