Product details
Overview
TLP3545(F) from Toshiba Electronic Devices & Storage Corporation is a normally-open photorelay IC comprising an infrared LED optically coupled to a photo MOSFET in a 6-pin DIP package. It delivers 3 A maximum ON-state current (A connection), 70 mΩ max ON-resistance, and 2500 Vrms isolation voltage - enabling solid-state replacement of mechanical relays in AC/DC power line switching applications.
For engineers reviewing the TLP3545(F) datasheet, TLP3545(F) pinout, TLP3545(F) application, or TLP3545(F) equivalent, key selection criteria include trigger LED current (≤3 mA), OFF-state output voltage rating (60 V min), thermal derating behavior, and A/B/C connection configuration options for load routing and current sharing.
Technical Context
The TLP3545(F) implements optical isolation between input (GaAs LED) and output (dual-channel N-channel MOSFET) stages, with internal photodiode array driving integrated MOSFET gates. Its A-connection topology shorts pins 4, 5, and 6 as parallel drain-source paths, supporting 3 A continuous conduction at ≤85°C ambient.
It operates with 5–48 V supply voltage, requires ≤3 mA LED trigger current, and achieves typical turn-on/turn-off times of 2 ms / 0.1 ms under 20 V, 200 Ω load conditions. Isolation performance meets UL 1577 and CSA Component Acceptance requirements at 2500 Vrms for 60 seconds.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Output Configuration | A-connection: Pins 4/5/6 internally shorted as parallel MOSFET drains/sources - enables 3 A continuous current handling with shared thermal path |
| ON-State Resistance | 70 mΩ max at 2 A, 25°C - ensures <0.15 V drop at 2 A, minimizing conduction loss in power switching |
| OFF-State Voltage | 60 V min - supports safe blocking of 24–48 V DC control lines and SELV AC circuits |
| Trigger LED Current | 3 mA max - compatible with standard MCU GPIO or low-power logic drivers without external amplification |
| Isolation Voltage | 2500 Vrms (60 s) - satisfies reinforced insulation requirements for industrial I/O and PLC modules |
| Operating Temperature | −40°C to +85°C - validated for use in factory automation enclosures and security system panels |
| Switching Speed | Turn-on: 5 ms max; Turn-off: 1 ms max - suitable for non-PWM, infrequent switching (e.g., motor start/stop, heater enable) |
Pinout & Package
Housed in a 6-pin DIP package (Toshiba package code 11-7A8S, 0.4 g typical weight), the TLP3545(F) uses through-hole mounting with 2.54 mm pitch and standard DIP footprint.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Anode | LED anode input - connect to current-limited DC source (e.g., MCU GPIO + series resistor) |
| 2 | Cathode | LED cathode return - tie to ground or logic low reference |
| 3 | N.C. | No internal connection - must remain unconnected per datasheet; floating or grounded both invalid |
| 4, 5, 6 | Drain/Source (A-connection) | Internally shorted MOSFET terminals - function as single high-current switch node (3 A rating applies across all three pins) |
Key Features
| Feature | Design Value |
|---|---|
| Normally-open (1-Form-A) operation | Zero leakage current in OFF state (≤1 µA at 60 V) - eliminates standby power draw in idle systems |
| Low ON-resistance MOSFET output | 70 mΩ max enables <0.3 W conduction loss at 3 A - reduces heatsinking needs in compact PCB layouts |
| UL/cUL safety certification | UL 1577 and CSA Component Acceptance File E67349 - simplifies regulatory approval for industrial end equipment |
| Multiple connection topologies | Supports A-, B-, and C-connections - allows design flexibility for current sharing, bidirectional blocking, or dual-switch configurations |
| High isolation capacitance margin | 0.8 pF typical input-to-output capacitance - preserves signal integrity in noise-sensitive analog measurement front-ends |
Applications
| Security Systems | Factory Automation (FA) |
|---|---|
Use Scenario: Isolated arming/disarming control of door locks, alarm sirens, and motion sensor power rails in commercial security panels. IC Role / Device Role / Timing Role: Solid-state relay replacing electromechanical units to eliminate contact wear and audible click noise during frequent activation cycles.

IC Role / Device Role / Timing Role: Maintenance-free load switch replacing electromechanical relays prone to contact welding in high-cycle coin validation events. Use Value: 3 A rating supports 24 V solenoid inrush; 6-pin DIP package allows direct through-hole replacement on legacy PCBs without redesign. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3546(F) | Same package and pinout; higher OFF-state voltage (100 V min) but lower ON-current (2 A max) | Better suited for 48–100 V DC bus switching; not recommended where >2.5 A continuous load is required | Select TLP3546(F) only when higher blocking voltage is critical and load current remains ≤2 A |
| PVG612 | SO-6 surface-mount package; 1.5 A max ON-current; 35 mΩ typical RON; no UL/cUL certification | Designed for space-constrained consumer electronics; lacks safety agency approvals for industrial use | Choose PVG612 only for cost-sensitive, non-certified applications with ≤1.5 A loads and SMT assembly |
Compared with TLP3546(F) and PVG612, the TLP3545(F) uniquely balances 3 A current capacity, 60 V blocking, UL/cUL certification, and through-hole DIP compatibility - making it the preferred choice for certified industrial control and security hardware requiring robust, field-proven relay replacement.

FAQ
What is the maximum continuous load current supported by the TLP3545(F)?
The TLP3545(F) supports up to 3 A continuous ON-state current in A-connection configuration at ambient temperatures ≤85°C. Derating applies above 25°C: −30 mA/°C for ambient temperatures ≥25°C. This rating assumes proper PCB copper area for heat dissipation and excludes pulsed operation limits. The TLP3545(F) must not be operated beyond its absolute maximum ratings, including 9 A pulsed current (100 µs, 10% duty).
Does the TLP3545(F) require an external gate resistor or snubber circuit?
No, the TLP3545(F) integrates all necessary drive circuitry for its internal photo-MOSFETs and does not require external gate resistors or snubbers. Its optical coupling and monolithic construction eliminate parasitic oscillation risks. However, a series current-limiting resistor (typically 220–470 Ω) is required on the LED input side to limit forward current to ≤25 mA per absolute maximum rating - the TLP3545(F) itself contains no internal LED current regulation.
Can the TLP3545(F) switch AC loads directly?
The TLP3545(F) is rated for DC-only operation with a 60 V minimum OFF-state output terminal voltage. It is not designed for direct AC line switching (e.g., 120/230 VAC) due to lack of zero-crossing detection, bidirectional blocking capability, or AC-rated isolation certification. For AC loads, use the TLP3545(F) to drive an external TRIAC or back-to-back MOSFET stage - never connect AC mains directly to the TLP3545(F) output pins.
What is the meaning of "A-connection" in the TLP3545(F) datasheet?
"A-connection" refers to the internal wiring configuration where pins 4, 5, and 6 are shorted together to form a single high-current output node - effectively paralleling three MOSFET channels. This configuration delivers the full 3 A rating and lowest RON (70 mΩ max). B- and C-connections reconfigure these pins for different topologies (e.g., dual independent switches), but only A-connection achieves the published 3 A/70 mΩ specifications for the TLP3545(F).
Is the TLP3545(F) RoHS compliant and halogen-free?
Yes, the TLP3545(F) complies with EU RoHS Directive 2011/65/EU and is halogen-free per Toshiba's environmental specifications. Lead-free soldering is supported at peak temperature 260°C for 10 seconds. Full material declarations and compliance documentation are available via Toshiba's official product page and authorized distributor portals - confirm latest status before high-volume procurement.
