Product details
Overview
TLP3475S(TP,E from Toshiba Electronic Devices & Storage Corporation is a normally-open photorelay IC comprising an infrared LED optically coupled to a photo MOSFET in S-VSON4T package. It delivers 0.4 A max on-state current, 1.5 Ω max on-resistance, and 12 pF typ output capacitance - enabling high-frequency signal switching in ATE probe cards and logic IC testers.
For engineers reviewing the TLP3475S(TP,E datasheet, TLP3475S(TP,E pinout, TLP3475S(TP,E application, or TLP3475S(TP,E equivalent, key selection criteria include its 60 V off-state voltage rating, 3 mA max trigger LED current, low CR product, and suitability for high-speed memory test instrumentation requiring minimal insertion loss and rapid edge fidelity.
Technical Context
The TLP3475S(TP,E implements optical isolation via GaAs LED–photo MOSFET coupling with internal photodiode array driving dual-channel MOSFETs configured as a single-pole, single-throw (1-Form-A) switch. Its design targets sub-500 ns switching (0.12 ms typ tON, 0.06 ms typ tOFF) under 20 V supply and 5 mA LED drive.
It operates as a two-terminal device: pins 1 and 2 are internally shorted (LED anode/cathode), and pins 3 and 4 are shorted (MOSFET drain terminals). This configuration eliminates source/drain asymmetry and supports bidirectional AC/DC load switching up to 60 V with 500 Vrms isolation.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3476S(TP,E | Same S-VSON4T package; 0.2 A max ION, 3.5 Ω max RON, 8 pF typ COFF | Lower current rating suits lower-power logic probing but insufficient for memory bus switching | Select when test loads draw ≤200 mA and ultra-low capacitance (<8 pF) is prioritized over current capacity |
| PS8501-AX | SO-4 package; 0.3 A max ION; 2.5 Ω max RON; 15 pF typ COFF; 3750 Vrms isolation | Larger footprint and higher isolation suit industrial PLC I/O modules, not space-constrained probe cards | Choose only if board area allows SO-4 and 3750 Vrms isolation is required for mains-referenced test fixtures |
Compared with TLP3475S(TP,E, the TLP3476S(TP,E trades 50% lower on-current for 33% lower output capacitance, while PS8501-AX sacrifices miniaturization and speed for industrial-grade isolation - making TLP3475S(TP,E optimal for high-density, high-speed ATE signal routing where size, speed, and 0.4 A capability are jointly critical.

FAQ
What is the maximum continuous on-state current rating for the TLP3475S(TP,E?
The TLP3475S(TP,E has a maximum continuous on-state current rating of 0.4 A at Ta ≤ 25°C, derating linearly to 0 mA at 125°C ambient. This rating applies to both pins 3 and 4, which are internally shorted as a common drain terminal. The 0.4 A capability enables direct switching of memory bus lines and logic tester channels without external current amplification.
Does the TLP3475S(TP,E support bidirectional signal routing?
Yes, the TLP3475S(TP,E supports bidirectional signal routing because its output structure consists of two shorted drain terminals (pins 3 and 4) connected to a symmetrical photo MOSFET channel. With no source/drain designation, it passes AC or DC signals equally in either direction - a key requirement for differential test signal paths in high-speed logic IC testers.
What is the recommended LED drive condition to ensure reliable turn-on of the TLP3475S(TP,E?
The TLP3475S(TP,E requires a maximum trigger LED current of 3 mA to guarantee turn-on across temperature and lifetime. A typical design uses a 5 mA drive (within absolute max rating) with a series resistor calculated from VF = 1.24 V (typ) at IF = 10 mA. For 3.3 V MCU GPIO, a 680 Ω resistor delivers ~4.3 mA - ensuring robust activation while staying within thermal limits.
How does the S-VSON4T package of the TLP3475S(TP,E impact PCB layout in high-frequency probe cards?
The S-VSON4T package of the TLP3475S(TP,E measures 1.45 mm × 2.0 mm with 1.4 mm max height, enabling dense placement directly adjacent to BGA or LGA test pads. Its low-inductance, short-pin construction minimizes parasitic loop area - critical for preserving signal integrity above 100 MHz. The absence of leads eliminates bond wire inductance found in SO-4 alternatives.
Is the TLP3475S(TP,E compliant with halogen-free and RoHS requirements?
Yes, the TLP3475S(TP,E is halogen-free per Toshiba's definition (Br/Cl ≤ 0.09 wt%, aggregate ≤ 0.15 wt% in encapsulant) and RoHS-compliant (EU Directive 2011/65/EU), indicated by the "E" suffix in the part number. Full compliance documentation, including material declarations and test reports, is available from Toshiba upon request for TLP3475S(TP,E qualification in regulated industries.
