Product details
Overview
TLP3441(TP,F from Toshiba Electronic Devices & Storage Corporation is a surface-mount, normally-open photorelay with 40 V OFF-state voltage, 140 mA max ON-state current, and 0.7 pF typical output capacitance, designed for high-speed signal switching in automatic test equipment.
For engineers reviewing the TLP3441(TP,F datasheet, TLP3441(TP,F pinout, TLP3441(TP,F application, or TLP3441(TP,F equivalent, key selection criteria include low COFF for fast toggling, VSON-4 package compatibility with fine-pitch PCB layouts, and guaranteed 500 Vrms isolation for tester channel safety.
Technical Context
The TLP3441(TP,F integrates an infrared LED optically coupled to a photo-MOSFET in a single VSON-4 package, with pins 1–2 electrically shorted as the input anode/cathode pair and pins 3–4 shorted as the output drain terminals. Its two-terminal configuration simplifies layout but requires external series resistance for LED current limiting.
It operates with a maximum trigger LED current of 3 mA and delivers ≤10 Ω ON-state resistance at 140 mA load, enabling low-loss switching of high-frequency logic signals up to 20 MHz bandwidth-critical for memory and logic IC testers requiring sub-200 µs turn-on/turn-off times.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OFF-state voltage | 40 V min - supports safe isolation of tester channels handling TTL/CMOS-level signals without breakdown. |
| ON-state resistance | 5 Ω typ., 10 Ω max - ensures <50 mV voltage drop at 100 mA, preserving signal integrity in precision measurement paths. |
| Output capacitance | 0.7 pF typ., 1.3 pF max - enables >20 MHz small-signal bandwidth and minimal crosstalk in dense ATE channel arrays. |
| Isolation voltage | 500 Vrms min - meets basic reinforced insulation requirements for functional safety in benchtop and rack-mounted testers. |
| Trigger LED current | 3 mA max - allows direct drive from standard 3.3 V/5 V logic outputs with only a 1 kΩ series resistor. |
| Switching time | 25 µs typ. tON / 50 µs typ. tOFF - supports ≥10 kHz repetitive switching in high-throughput test sequences. |
Pinout & Package
VSON-4 (Toshiba package code 11-2D1A), 2.0 × 1.25 mm body, 0.5 mm pitch, 10 mg typical weight, non-leaded surface-mount construction.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | LED anode | Input terminal for forward biasing infrared LED; must be connected in series with current-limiting resistor. |
| 2 (Cathode) | LED cathode | Completes LED drive path; pins 1 and 2 are internally shorted as a two-terminal input device. |
| 3 (Drain) | MOSFET drain | One side of output switch; pins 3 and 4 are internally shorted to form a single 2-pin output port. |
| 4 (Drain) | MOSFET drain | Redundant drain connection for low-inductance, high-current output routing; no separate source terminal. |
Key Features
| Feature | Design Value |
|---|---|
| Normally-open (1-Form-A) topology | Ensures default open-circuit state during power loss or control failure-critical for fail-safe ATE channel isolation. |
| Low output capacitance (0.7 pF typ.) | Minimizes signal distortion and timing skew when switching high-speed digital waveforms in parallel test channels. |
| Guaranteed 500 Vrms isolation | Permits safe sharing of ground references across isolated tester subsystems without risk of leakage-induced measurement error. |
| Surface-mount VSON-4 footprint | Enables compact placement in high-density PCB layouts typical of modular ATE backplanes and probe card interfaces. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| PVG612A | Higher 60 V OFF-state rating; 1.2 pF COFF (typ.); SO-4 package (3.5 × 4.6 mm) | Better suited for higher-voltage industrial I/O modules; larger footprint limits ATE density | Choose PVG612A when >40 V isolation or legacy SOIC assembly is required. |
| APV1121S | Lower 1.5 Ω RON (typ.); 1.5 pF COFF (typ.); same VSON-4 package | Optimized for low-loss analog switching but slower tOFF (120 µs typ.) | Choose APV1121S when ON-resistance dominates design priority over speed. |
Compared with PVG612A and APV1121S, the TLP3441(TP,F offers the best balance of ultra-low COFF, compact VSON-4 size, and sufficient 40 V rating for logic-level ATE switching-making it optimal for space-constrained, high-bandwidth test channel designs.

FAQ
What is the maximum continuous ON-state current rating for the TLP3441(TP,F?
The TLP3441(TP,F has a maximum continuous ON-state current rating of 140 mA at Ta = 25 °C, derating linearly to zero at 125 °C junction temperature. This rating assumes proper PCB copper area for thermal dissipation and applies to steady-state DC loads-not pulsed operation, which allows up to 420 mA for 100 ms at 10% duty cycle. The TLP3441(TP,F must not exceed its absolute maximum ratings under any condition.
Does the TLP3441(TP,F require an external current-limiting resistor on the LED side?
Yes, the TLP3441(TP,F requires an external series resistor to limit LED forward current to ≤3 mA (max trigger) and ≤30 mA (absolute max). For example, with a 3.3 V supply and 1.27 V typical VF, a 680 Ω resistor sets IF ≈ 3.0 mA. The TLP3441(TP,F datasheet specifies this requirement explicitly in Recommended Operating Conditions and Absolute Maximum Ratings sections.
What is the meaning of the "(TP,F" suffix in TLP3441(TP,F?
The "(TP,F" suffix in TLP3441(TP,F indicates tape-and-reel packaging (TP) and RoHS-compliant finish (F), per Toshiba's ordering nomenclature. TP denotes embossed plastic tape per EIA-481 standard, and F confirms compliance with EU Directive 2011/65/EU on hazardous substances. The TLP3441(TP,F is supplied in reels of 3000 units, as shown in the ordering example.
Can the TLP3441(TP,F be used in AC signal switching applications?
The TLP3441(TP,F supports bidirectional AC signal switching up to its 40 V peak OFF-state voltage rating, provided the signal remains within ±40 V and does not exceed the device's power dissipation limits. Its photo-MOSFET output structure inherently handles both polarities, but designers must ensure that peak reverse voltage and RMS heating remain within specifications-verified using the TLP3441(TP,F electrical characteristics table and derating curves.
What is the thermal resistance (RθJA) of the TLP3441(TP,F in standard JEDEC PCB layout?
Toshiba does not publish RθJA for the TLP3441(TP,F in its official datasheet; thermal performance depends heavily on PCB copper area and layer stack-up. However, the device's 196 mW max output power dissipation and 125 °C max junction temperature imply that ≥25 mm² of 1-oz copper on the drain pads (pins 3 and 4) is recommended for full 140 mA operation at 85 °C ambient. The TLP3441(TP,F land pattern dimensions on page 14 provide guidance for thermal pad implementation.
