Product details
Overview
TLP176AM(TPL,E 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 SO6 (11-4M1S) package. It delivers 700 mA max ON-state current, 2 Ω max ON-resistance, and 60 V min OFF-state voltage - enabling solid-state replacement of mechanical relays in industrial control and battery management systems.
For engineers reviewing the TLP176AM(TPL,E datasheet, TLP176AM(TPL,E pinout, TLP176AM(TPL,E application, or TLP176AM(TPL,E equivalent, this device offers verified isolation (3750 Vrms), UL 1577/UL 508/cUL/VDE safety certification, and precise switching timing (2–3 ms turn-on, 0.1–0.5 ms turn-off) for high-reliability on/off control under 48 V supply conditions.
Technical Context
The TLP176AM(TPL,E implements a single-pole, normally-open (1-Form-A) solid-state switch architecture with galvanic isolation between input LED and output photo-MOSFET. Its internal two-terminal configuration shorts pins 1&3 (anode/cathode) and pins 4&6 (drain/drain), simplifying PCB layout while maintaining 5.0 mm creepage and clearance distances.
It operates across –40 °C to +110 °C ambient temperature, supports 3 mA max trigger LED current, and sustains 700 mA continuous ON-state current with derating above 25 °C. The device meets UL 508 for industrial control equipment and EN 60747-5-5 when ordered with V4 option - though TLP176AM(TPL,E itself is not VDE-certified by default.

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PVG612A | Higher 1.2 A ON-current, 1.2 Ω RON, but requires 5 mA IFT and operates only to +85 °C | Better suited for higher-current solenoid drives; less suitable for high-ambient BMS or FA enclosures | Select when >700 mA load current is required and ambient stays ≤85 °C |
| TLP3554 | Same SO6 package, 60 V VOFF, but lower 400 mA ION and 3.5 Ω RON; certified to VDE EN 60747-5-5 out-of-box | Preferred where VDE certification is mandatory without ordering V4 variant; trade-off in conduction loss | Select when VDE approval is required immediately and 400 mA load current suffices |
Compared with PVG612A and TLP3554, the TLP176AM(TPL,E provides optimal balance of 700 mA current handling, 110 °C max operating temperature, and UL 508 compliance - making it ideal for thermally demanding industrial controls where VDE is optional and higher current than TLP3554 is needed.

FAQ
What is the maximum continuous ON-state current rating for the TLP176AM(TPL,E?
The TLP176AM(TPL,E has a maximum continuous ON-state current rating of 700 mA at Ta = 25 °C, derating linearly to 455 mA at 85 °C per UL 508 specifications. This rating applies to the combined output terminals (pins 4 & 6), which are internally shorted and function as a single drain node. Exceeding this current may cause thermal runaway or irreversible degradation of the photo-MOSFET channel.
Does the TLP176AM(TPL,E meet VDE safety standards without additional ordering codes?
No, the TLP176AM(TPL,E does not include VDE EN 60747-5-5 certification by default. VDE approval requires ordering the V4 option variant (e.g., TLP176AM(V4,E). The standard TLP176AM(TPL,E is UL-recognized (UL 1577 and UL 508) and cUL-recognized, but lacks VDE documentation unless explicitly specified in the part number.
What is the pin configuration and internal connection scheme of the TLP176AM(TPL,E?
The TLP176AM(TPL,E uses a 4-terminal SO6 (11-4M1S) package with internal shorting: pins 1 and 3 are electrically joined as the LED anode/cathode pair, and pins 4 and 6 are internally connected as the photo-MOSFET drain terminals. Pin 2 and pin 5 are unused and must remain unconnected. This two-terminal functional layout simplifies PCB routing and reduces parasitic inductance in high-speed switching paths.
Can the TLP176AM(TPL,E be used to replace mechanical relays in 24 V DC control circuits?
Yes, the TLP176AM(TPL,E is explicitly designed for mechanical relay replacement in 24 V DC control circuits. With its 60 V minimum OFF-state voltage, 700 mA ON-current, and 2 Ω maximum ON-resistance, it safely switches typical solenoid, indicator, and valve loads found in PLC outputs and security panels - eliminating contact wear, bounce, and EMI associated with electromechanical relays.
What is the recommended LED forward current to reliably trigger the TLP176AM(TPL,E?
The TLP176AM(TPL,E is guaranteed to turn ON with ≤3 mA LED forward current (IFT) at 25 °C. For robust operation across temperature and unit-to-unit variation, a design target of 5 mA is recommended - well within the 50 mA absolute maximum rating and compatible with standard microcontroller GPIOs. This ensures consistent activation even at –40 °C or after 10+ years of LED aging.
