Product details
Overview
TLP3403R(TP,F from Toshiba Electronic Devices & Storage Corporation is a surface-mount photorelay with integrated input resistor, optical coupling between infrared LED and photo-MOSFET, 20 V off-state voltage rating, 1 A max on-state current, and 0.22 Ω max on-resistance - used for battery control, instrument switching, and high-speed IC tester signal routing.
For engineers reviewing the TLP3403R(TP,F datasheet, TLP3403R(TP,F pinout, TLP3403R(TP,F application, or TLP3403R(TP,F equivalent, key selection criteria include isolation voltage (500 Vrms), low output capacitance (0.5 pF typ.), VSONR4 package footprint, and 0.17 ms turn-on time under 10 V supply.
Technical Context
The TLP3403R(TP,F implements optically isolated MOSFET switching using gallium arsenide LED and silicon photo-MOSFET die in a single VSONR4 package. It operates as a normally-open (1-Form-A) solid-state relay with internal input resistor eliminating external bias components.
Its electrical interface separates low-voltage logic-side input (max 6 V forward voltage) from load-side output (20 V off-state, 1 A continuous), with galvanic isolation rated at 500 Vrms and total input-to-output capacitance of 1 pF typical - enabling noise-immune signal switching in precision test equipment.

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3406S(TP,F | Higher off-state voltage (60 V), higher on-resistance (0.35 Ω max), same VSONR4 package | Better suited for industrial PLC I/O modules requiring 48 VDC isolation; less optimal for low-voltage high-speed testers | Select when off-state voltage margin >40 V is required and 0.17 ms turn-on time remains acceptable |

FAQ
What is the maximum continuous ON-state current rating for the TLP3403R(TP,F?
The TLP3403R(TP,F has a maximum continuous ON-state current rating of 1 A at Ta ≤ 25 °C, derating linearly to 0 A at 110 °C ambient. This rating applies with both drain pins (3 and 4) connected in parallel as specified in the internal circuit diagram. The TLP3403R(TP,F achieves this with 0.22 Ω max on-resistance, limiting power dissipation to 220 mW at full load - verified per Toshiba's Absolute Maximum Ratings table.
Does the TLP3403R(TP,F require an external current-limiting resistor on the input side?
No, the TLP3403R(TP,F integrates a built-in input resistor, eliminating the need for an external series resistor. This design reduces PCB area and component count while ensuring proper LED biasing across its recommended 3–6 V input voltage range. The TLP3403R(TP,F's internal resistor enables direct connection to 3.3 V or 5 V logic outputs without additional passive components - confirmed in Toshiba's General section and Electrical Characteristics tables.
What is the isolation voltage specification for the TLP3403R(TP,F, and how is it tested?
The TLP3403R(TP,F provides 500 Vrms minimum isolation voltage between input and output sides, tested per IEC 60747-5-5 with AC 60 s duration at ≤60 % relative humidity. This rating ensures safe operation in battery monitoring and instrumentation applications where control and measurement circuits operate at different ground potentials. The TLP3403R(TP,F maintains this isolation performance across its full operating temperature range of −40 to +110 °C.
Can the TLP3403R(TP,F be used in high-frequency signal switching applications?
Yes, the TLP3403R(TP,F supports high-frequency signal routing due to its 0.5 pF typical output capacitance and 0.17 ms typical turn-on time. These parameters enable clean switching of digital signals up to 100 MHz in logic IC testers and memory validation systems. The TLP3403R(TP,F's low capacitance minimizes signal rise-time degradation and crosstalk - validated in Toshiba's Coupled Electrical Characteristics and Switching Characteristics sections.
What package type does the TLP3403R(TP,F use, and what are its dimensions?
The TLP3403R(TP,F uses the VSONR4 surface-mount package (Toshiba code 11-3D1), measuring 2.8 mm × 1.5 mm × 1.3 mm with a typical weight of 0.01 g. Its 4-pin non-leaded construction features pins 1–2 shorted as the LED anode/cathode pair and pins 3–4 shorted as the MOSFET drain terminals - enabling ultra-compact placement in space-constrained test equipment PCBs. The TLP3403R(TP,F's land pattern is documented in Toshiba's Package Dimensions drawing.
