Product details
Overview
TLP4590A(D4TP1,F from Toshiba Electronic Devices & Storage Corporation is a normally closed (1-Form-B) photo MOSFET relay with 60 V OFF-state voltage, 1.2 A ON-state current (A-connection), and 0.6 Ω max ON-resistance, housed in a 6-pin DIP through-hole package. It replaces mechanical relays in HVAC control, security system I/O isolation, and factory automation signal switching where space and reliability are critical.
For engineers reviewing the TLP4590A(D4TP1,F datasheet, TLP4590A(D4TP1,F pinout, TLP4590A(D4TP1,F application, or TLP4590A(D4TP1,F equivalent, this device offers VDE-approved isolation (EN 60747-5-5), low 2 mA max trigger LED current, and three configurable output connections (A/B/C) for flexible load switching topologies.
Technical Context
The TLP4590A(D4TP1,F integrates an infrared LED optically coupled to a dual-channel MOSFET output stage, enabling galvanic isolation between input control and output power paths. Its internal structure supports A-connection (single drain-source path), B-connection (parallel dual-path), and C-connection (series dual-path) configurations, each with distinct current and resistance ratings.
It delivers 5000 Vrms isolation per UL 1577 and VDE EN 60747-5-5 (with D4 option), features 0.3 mm minimum internal isolation thickness, and maintains <1 µA OFF-state leakage at 60 V. Switching times are 0.3–2 ms turn-on and 2–3 ms turn-off under 20 V/200 Ω load conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Isolation Voltage | 5000 Vrms - meets safety-critical insulation requirements for industrial control and medical auxiliary circuits |
| OFF-State Voltage | 60 V min - supports DC loads up to 60 V without breakdown in open-circuit condition |
| ON-State Current | 1200 mA max (A-connection) - handles typical solenoid, valve, or indicator loads in FA systems |
| ON-State Resistance | 0.6 Ω max - limits conduction loss to <0.86 W at 1.2 A, reducing thermal stress |
| Trigger LED Current | 2 mA max - enables direct drive from low-power MCU GPIOs without external amplification |
| Turn-On/Off Time | 0.3–2 ms / 2–3 ms - suitable for medium-speed sequencing (e.g., HVAC damper actuation) |
| Creepage/Clearance | 7.0 mm (TLP4590A variant) - satisfies IEC 61800-5-1 pollution degree 2 spacing requirements |
Pinout & Package
Housed in a 6-pin DIP through-hole package (TOSHIBA 11-7A8S, 7.62-mm pitch), the TLP4590A(D4TP1,F provides optical isolation between input and output sides with dedicated anode/cathode and dual-drain/source terminals.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode - connects to MCU/driver positive output; requires current-limiting resistor |
| 2 | Cathode | LED cathode - ties to ground or driver low-side switch; defines input polarity |
| 4 | Drain D1 | First MOSFET drain - used in A/B/C connection modes; forms one side of output switch |
| 5 | Source | Common source node - referenced output terminal for all configurations; must be tied to load return |
| 6 | Drain D2 | Second MOSFET drain - enables parallel (B) or series (C) output topologies with D1 |
Key Features
| Feature | Design Value |
|---|---|
| Normally Closed (1-Form-B) | Default conductive state ensures fail-safe operation in alarm or shutdown circuits |
| VDE-Approved Isolation | D4 option certifies compliance with EN 60747-5-5 for reinforced insulation in EU-sourced equipment |
| Triple Output Configuration | A/B/C wiring options allow optimization for current capacity (1.2 A), on-resistance (0.2 Ω), or voltage rating (1200 mA pulsed) |
| Low Trigger Threshold | 2 mA max IFC enables compatibility with 3.3 V logic and battery-powered controllers |
| High OFF-State Resistance | <1 µA IOFF at 60 V ensures minimal leakage in standby mode for energy-sensitive applications |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3558A | Higher 100 V OFF-state voltage; 1.5 A ON-current; SOIC-6 surface-mount package | Better suited for higher-voltage industrial sensors; not pin-compatible due to SMT footprint and different pinout | Select when board space is constrained and 100 V load handling is required |
| PVG612 | 1-Form-A (normally open); 400 mA ON-current; 1.5 Ω RON; DIP-6 package | Requires external pull-up for NO logic; lower current rating limits use to signal-level loads only | Choose for cost-sensitive, low-current isolation where NC functionality is not mandatory |
Compared with TLP3558A and PVG612, the TLP4590A(D4TP1,F uniquely combines normally closed operation, 60 V/1.2 A rating, and VDE certification in a through-hole DIP package-making it optimal for retrofitting mechanical relays in legacy industrial controls requiring fail-safe closure.

FAQ
What is the isolation rating and safety certification of the TLP4590A(D4TP1,F?
The TLP4590A(D4TP1,F provides 5000 Vrms isolation and carries VDE approval per EN 60747-5-5 (with D4 option), UL 1577 recognition (File E67349), and cUL certification. These ratings confirm suitability for reinforced insulation in industrial control equipment operating up to 300 V working voltage, provided layout creepage and clearance comply with IEC 61800-5-1.
How does the TLP4590A(D4TP1,F support normally closed (NC) operation in circuit design?
The TLP4590A(D4TP1,F implements true 1-Form-B (normally closed) behavior via internal MOSFET topology that conducts by default and opens only when the input LED is energized. This fail-safe characteristic ensures continuity in alarm circuits or safety interlocks even during controller power loss, unlike normally open alternatives requiring active drive to close.
What are the valid output connection modes for the TLP4590A(D4TP1,F and how do they affect performance?
The TLP4590A(D4TP1,F supports A-connection (1200 mA, 0.6 Ω), B-connection (1200 mA, 0.2 Ω), and C-connection (2400 mA pulsed, 0.1 Ω), selectable via external PCB wiring of pins 4, 5, and 6. Each mode trades off current capacity, on-resistance, and thermal dissipation-B-mode lowers RON for reduced heat, while C-mode enables higher peak currents for motor start-up.
Can the TLP4590A(D4TP1,F be driven directly from a 3.3 V microcontroller GPIO?
Yes-the TLP4590A(D4TP1,F requires only 2 mA maximum trigger LED current and exhibits 1.4 V max forward voltage, allowing direct drive from 3.3 V GPIOs using a 1 kΩ series resistor. No level-shifting or buffer stages are needed, simplifying interface design in compact embedded controllers.
What is the recommended soldering profile for the TLP4590A(D4TP1,F through-hole package?
For the TLP4590A(D4TP1,F's 6-pin DIP package, flow soldering at 260 °C for ≤10 seconds is recommended. Preheating to 150 °C for 60–120 seconds prior to soldering improves wetting. Avoid exceeding 260 °C at the lead tip for more than 10 seconds or 350 °C for more than 3 seconds to prevent internal bond wire damage or encapsulant degradation.
