Product details
Overview
TLP4590A(D4TP5,F from Toshiba Electronic Devices & Storage Corporation is a normally closed (1-Form-B) photo MOSFET relay in a 6-pin DIP through-hole package, featuring 60 V OFF-state voltage, ≤2 mA trigger LED current, and ≤0.6 Ω ON-state resistance. It replaces mechanical relays in HVAC controls, security system I/O isolation, and factory automation signal switching where space and reliability are critical.
For engineers reviewing the TLP4590A(D4TP5,F datasheet, TLP4590A(D4TP5,F pinout, TLP4590A(D4TP5,F application, or TLP4590A(D4TP5,F equivalent, this device offers VDE-approved isolation (EN 60747-5-5), 5000 Vrms withstand voltage, and taping-compatible packaging for automated PCB assembly in industrial control modules.
Technical Context
The TLP4590A(D4TP5,F integrates an infrared LED optically coupled to a dual-channel MOSFET output stage configured as a single-pole double-throw (SPDT) switch with normally closed (NC) functionality. Its internal structure supports three connection modes (A/B/C), enabling flexible load routing without external components.
It operates with galvanic isolation between input and output sides, where pins 1–2 form the LED anode/cathode pair and pins 4–5–6 serve as drain-source-drain terminals for bidirectional AC/DC switching up to 1.2 A continuous per path. The D4 option confirms VDE compliance per EN 60747-5-5 and EN 62368-1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OFF-state voltage | 60 V min - supports safe interruption of 24–48 V DC control circuits without arcing. |
| Trigger LED current | ≤2 mA max - enables direct drive from low-power MCU GPIOs without buffer transistors. |
| ON-state resistance | ≤0.6 Ω max - limits conduction loss to <0.86 W at 1.2 A, reducing thermal stress in compact enclosures. |
| Isolation voltage | 5000 Vrms min - meets reinforced insulation requirements for Class I equipment in industrial environments. |
| Turn-on/off time | 0.3–2 ms / 2–3 ms - ensures deterministic timing for PLC scan-cycle-synchronized I/O switching. |
| Storage temperature | −55 to +125 °C - allows long-term warehouse storage and operation in uncontrolled ambient conditions. |
Pinout & Package
Housed in a 6-pin DIP through-hole package (TOSHIBA 11-7A805S), the TLP4590A(D4TP5,F features 7.62-mm lead pitch and 0.3 mm minimum internal isolation thickness. Creepage and clearance distances meet UL, cUL, and VDE safety standards for industrial-grade isolation.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED input terminal requiring series current-limiting resistor for 2 mA trigger threshold. |
| 2 | Cathode | LED return path; referenced to system ground on input side. |
| 4 | Drain D1 | Output channel 1 drain; connects to load high-side in A/B/C configurations. |
| 5 | Source | Common source node; ties both MOSFET channels together for SPDT operation. |
| 6 | Drain D2 | Output channel 2 drain; forms NC contact with Source when LED is off. |
Key Features
| Feature | Design Value |
|---|---|
| Normally closed (1-Form-B) | Provides fail-safe operation: load remains connected until LED is energized, critical for emergency stop circuits. |
| VDE-certified isolation | EN 60747-5-5 and EN 62368-1 compliance confirmed by D4 option - eliminates need for additional safety certification effort. |
| Low ON-resistance | 0.6 Ω max enables 1.2 A continuous current handling with minimal self-heating in confined spaces. |
| High OFF-state voltage | 60 V rating supports compatibility with 48 V DC industrial buses and legacy 24 VAC control systems. |
| Tape-and-reel packaging | TP5 taping (1500 pcs/reel) enables seamless SMT placement despite through-hole footprint - reduces manual assembly cost. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3545A | Higher 100 V OFF-state voltage; 0.4 Ω RON; same 6-pin DIP but no VDE option. | Preferred for 48–72 V DC battery-backed systems; lacks EN 60747-5-5 certification. | Select when higher voltage margin is required and safety certification is handled externally. |
| PVG612 | Surface-mount SO-6 package; 40 V OFF-state; 1.0 A rating; UL/cUL only (no VDE). | Better suited for space-constrained PCBs; unsuitable for 60 V applications or VDE-mandated designs. | Choose for high-density layouts where through-hole mounting is impractical and voltage stress is ≤40 V. |
Compared with TLP4590A(D4TP5,F, the TLP3545A offers greater voltage headroom but requires external safety validation, while the PVG612 saves board area at the cost of isolation rating and load current capability - making TLP4590A(D4TP5,F optimal for certified industrial I/O where reliability and regulatory alignment are prioritized.

FAQ
What is the isolation voltage rating of the TLP4590A(D4TP5,F?
The TLP4590A(D4TP5,F has a guaranteed minimum isolation voltage of 5000 Vrms (AC, 60 s, R.H. ≤ 60 %), verified per UL 1577, CSA Component Acceptance Service No.5A, and VDE EN 60747-5-5 - making it suitable for reinforced insulation in industrial mains-connected equipment. This rating applies to the TLP4590A(D4TP5,F variant due to its D4 option designation confirming VDE approval.
Does the TLP4590A(D4TP5,F support AC load switching?
Yes, the TLP4590A(D4TP5,F supports bidirectional AC load switching via its dual-MOSFET output configuration (pins 4–5–6). Its 60 V OFF-state voltage and low 0.6 Ω ON-resistance allow reliable operation with 24–48 VAC control circuits, such as those found in HVAC actuators and security system transformers - confirmed in Toshiba's Application Note Chapter 14 circuit examples.
What does the "D4TP5" suffix mean in TLP4590A(D4TP5,F?
The "D4" denotes VDE certification per EN 60747-5-5 and EN 62368-1, while "TP5" specifies tape-and-reel packaging with 1500 units per reel. The "F" indicates RoHS-compliant finish. Together, TLP4590A(D4TP5,F identifies the VDE-approved, surface-mount-ready (taped), lead-free version of the TLP4590A photorelay - distinct from non-D4 or bulk-packaged variants.
Can the TLP4590A(D4TP5,F replace a mechanical relay in a 1.2 A DC load?
Yes, the TLP4590A(D4TP5,F is rated for 1.2 A continuous ON-state current (A-connection, Ta = 25 °C) and 2.4 A pulsed current, with ≤0.6 Ω ON-resistance ensuring <0.86 W conduction loss. Its 60 V OFF-state voltage safely interrupts 24–48 V DC loads - validated in Toshiba's Absolute Maximum Ratings Table 8 and Electrical Characteristics Table 10 for the TLP4590A(D4TP5,F family.
What is the recommended LED drive circuit for the TLP4590A(D4TP5,F?
A series current-limiting resistor is required between MCU GPIO and pin 1 (anode), sized to deliver ≤2 mA forward current at the GPIO voltage (e.g., 3.3 V). For a 3.3 V supply and typical 1.27 V LED forward voltage, a 1.0 kΩ resistor yields ~2.03 mA - meeting the trigger threshold while staying within absolute maximum IF = 20 mA. This design is confirmed in Toshiba's Figure 14.1 (A-connection) and Table 10.
