Product details
Overview
TLP3542(F) from Toshiba Electronic Devices & Storage Corporation is a photo-MOS solid-state relay in a 6-pin DIP package, featuring bi-directional switching capability, 2.5 A maximum on-state current, 100 mΩ max on-resistance, and 2500 Vrms isolation voltage. It replaces electromechanical relays in test equipment, data recording systems, and precision measurement instrumentation where low leakage, high reliability, and zero-crossing–free AC/DC switching are required.
For engineers reviewing the TLP3542(F) datasheet, TLP3542(F) pinout, TLP3542(F) application, or TLP3542(F) equivalent, key selection criteria include verified 60 V peak off-state voltage, sub-3 mA trigger LED current, temperature-derated on-state current up to 85°C, and UL/cUL recognition per File E67349 - all critical for industrial control and automated test system design.
Technical Context
The TLP3542(F) integrates a GaAs infrared LED optically coupled to a dual-channel photo-MOS FET output stage configured as a single-pole, single-throw (1-Form-A) bi-directional switch. Its output structure supports symmetrical conduction across Drain D1 and Drain D2 terminals without polarity dependence.
It operates with a minimum trigger LED current of 1 mA (typ.) at 1.0 A load, achieves turn-on/turn-off times of 1.0–3.0 ms / 0.2–0.6 ms respectively under 20 V, 200 Ω conditions, and maintains <1.5 nA off-state current at 20 V - enabling high-impedance signal routing and low-power standby operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Off-State Voltage | 60 V min - supports safe switching of 48 V DC power rails and 34 V RMS AC signals without breakdown. |
| On-State Current | 2.5 A max - enables direct control of solenoids, heaters, and medium-power loads without external amplification. |
| On-State Resistance | 100 mΩ max - limits conduction loss to ≤625 mW at full load, reducing thermal stress in compact PCB layouts. |
| Trigger LED Current | 3 mA max - ensures compatibility with standard microcontroller GPIOs and low-power logic drivers. |
| Isolation Voltage | 2500 Vrms min - meets reinforced insulation requirements for functional safety in Class I equipment. |
| Output Capacitance | 600 pF max - preserves signal integrity in high-frequency switching applications up to ~100 kHz. |
Pinout & Package
Package: 6-pin plastic DIP (DIP6), JEDEC MS-001 variant, 0.4 g typical weight, lead-free and RoHS-compliant per Toshiba specification.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | ANODE | LED anode input - connects to current-limited drive source (e.g., MCU + series resistor). |
| 2 | CATHODE | LED cathode return - ties to ground or active-low driver for optical activation. |
| 3 | N.C. | No internal connection - must remain unconnected; floating or grounded per layout best practice. |
| 4 | DRAIN D1 | Bi-directional output terminal 1 - forms one side of the MOSFET channel; interchangeable with Pin 6. |
| 6 | DRAIN D2 | Bi-directional output terminal 2 - completes the switch path; no polarity sensitivity between Pins 4 and 6. |
Key Features
| Feature | Design Value |
|---|---|
| Bi-directional Output | Enables AC and DC load switching without external diodes or H-bridge circuitry. |
| Low On-Resistance | 65 mΩ typical at 2 A ensures minimal I²R heating and stable voltage drop across wide temperature range. |
| High Isolation Integrity | 0.8 pF input-to-output capacitance and >10¹⁰ Ω isolation resistance suppress noise coupling in sensitive analog paths. |
| UL/cUL Recognition | Certified to UL 1577 and CSA Component Acceptance Service No. 5A (File E67349) for end-equipment compliance. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar solid-state relay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3544(F) | Same DIP6 package, but rated for 4 A on-state current and 150 mΩ max RON; higher power dissipation (1 W). | Better suited for higher-current loads (e.g., 48 V DC motors), but requires larger thermal pad or heatsinking. | Select when load current exceeds 2.5 A and board space allows for increased thermal management. |
| PS7141-AL | SSR in SOIC-6 package; 1.5 A rating, 250 mΩ RON, 5000 Vrms isolation; lower trigger current (0.5 mA typ.). | Preferred for space-constrained designs and higher isolation requirements, but limited to ≤1.5 A loads. | Choose for compact surface-mount layouts and enhanced isolation, accepting reduced current capacity. |
Compared with TLP3542(F), the TLP3544(F) offers higher current handling at the cost of thermal overhead, while the PS7141-AL trades current rating for miniaturization and superior isolation - making each suitable for distinct trade-offs in test, measurement, and control systems.

FAQ
What is the maximum operating temperature for the TLP3542(F)?
The TLP3542(F) has an operating temperature range of −20°C to +85°C, with derated on-state current beginning at 40°C (−22 mA/°C). At 85°C ambient, its usable on-state current drops to approximately 1.5 A. This thermal profile makes the TLP3542(F) suitable for enclosed industrial enclosures without forced cooling, provided PCB copper area and airflow meet Toshiba's recommended layout guidelines.
Does the TLP3542(F) support AC load switching?
Yes, the TLP3542(F) supports bidirectional AC load switching due to its symmetrical photo-MOS output structure connecting Drain D1 and Drain D2. Unlike unidirectional optocouplers, it conducts equally in both directions with identical on-resistance and voltage ratings - enabling true AC switching without external diodes or bridge configurations. This behavior is confirmed in Toshiba's schematic and absolute maximum ratings table.
What is the isolation voltage rating of the TLP3542(F) and how is it tested?
The TLP3542(F) is rated for 2500 Vrms isolation voltage (AC, 60 s, R.H. ≤ 60%), verified with Pins 1–2–3 shorted as one terminal and Pins 4–6 shorted as the other. This test method complies with UL 1577 and CSA Component Acceptance Service standards (File E67349). The isolation barrier uses molded resin encapsulation and internal spacing validated per IEC 60747-5-5, ensuring functional safety in Class I equipment.
Can the TLP3542(F) be driven directly from a 3.3 V microcontroller GPIO?
Yes - the TLP3542(F) has a maximum trigger LED current of 3 mA and typical forward voltage of 1.33 V at 10 mA. With a 3.3 V GPIO, a 680 Ω series resistor delivers ~3.0 mA, satisfying the IFT requirement. Toshiba's recommended operating condition specifies 10–20 mA forward current, so 3.3 V drive is viable for most applications, though 5 V drive improves noise margin and speed consistency.
Is the TLP3542(F) RoHS compliant and lead-free?
Yes, the TLP3542(F) is RoHS compliant and lead-free, as confirmed by Toshiba's official product documentation and environmental compliance statements. The device uses matte tin plating on leads and halogen-free molding compound. Full material declarations and substance reports are available through Toshiba's official portal using the part number TLP3542(F) and date code suffix.
