Product details
Overview
TLP3442(TP,F from Toshiba Electronic Devices & Storage Corporation is a surface-mount photorelay with normally-open (1-Form-A) configuration, 40 V OFF-state voltage rating, 100 mA max ON-state current, and ultra-low 0.3 pF typical output capacitance-enabling fast switching of high-frequency signals in automated test equipment.
For engineers reviewing the TLP3442(TP,F datasheet, TLP3442(TP,F pinout, TLP3442(TP,F application, or TLP3442(TP,F equivalent, this device serves as a compact, high-speed signal path switch where low COFF, tight IFT control (≤3 mA), and 500 Vrms isolation are critical for tester channel integrity and signal fidelity.
Technical Context
The TLP3442(TP,F integrates an infrared LED optically coupled to a photo-MOSFET in a VSON 4-pin package (Toshiba designation 11-2D1A), with pins 1–2 internally shorted as input terminals and pins 3–4 shorted as output drain terminals-functioning as a two-terminal solid-state relay.
Its design targets high-speed digital signal routing: low 20 µs typical turn-on/45 µs turn-off times at 20 V supply and 5 mA LED drive, combined with 15 Ω typical ON-resistance and <1 nA OFF-state leakage, support reliable switching in logic IC and memory testers operating up to 100 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| OFF-state voltage | 40 V min - supports safe blocking of tester channel bias voltages up to 32 V recommended operating range |
| ON-state current | 100 mA max - handles standard logic-level load currents without derating below 85°C |
| Output capacitance | 0.3 pF typ., 0.6 pF max - minimizes signal distortion and crosstalk in >100 MHz digital paths |
| Trigger LED current | 3 mA max - enables direct drive from low-power FPGA I/O or microcontroller GPIO without external amplification |
| Isolation voltage | 500 Vrms min - provides safety and noise immunity between tester controller and DUT interface domains |
| ON-resistance | 15 Ω typ., 20 Ω max - ensures ≤2 V drop at 100 mA, preserving signal swing in 3.3 V/5 V systems |
| Switching time | 20 µs tON / 45 µs tOFF typ. - meets timing budgets for sub-50 kHz channel scan rates in ATE |
Pinout & Package
VSON 4-pin package (Toshiba 11-2D1A), 1.6 × 1.6 mm footprint, 0.5 mm pitch, 10 mg typical weight, designed for high-density SMT placement in ATE probe cards and instrument backplanes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Anode) | LED anode | Input terminal for forward-biased IR LED; paired with Pin 2 for single-ended LED drive |
| 2 (Cathode) | LED cathode | Completes LED circuit; Pins 1 and 2 are internally shorted-used as one 2-pin LED port |
| 3 (Drain) | MOSFET drain | Output switch terminal; internally shorted to Pin 4 for dual-drain parallel connection |
| 4 (Drain) | MOSFET drain | Redundant drain terminal-lowers effective RDS(on) and thermal resistance when both used |
Key Features
| Feature | Design Value |
|---|---|
| Normally-open (1-Form-A) topology | Ensures fail-safe open-circuit state during power loss or LED failure-critical for tester channel protection |
| Ultra-low output capacitance | 0.3 pF typical COFF preserves signal edge integrity and bandwidth in >100 MHz test signal paths |
| Low trigger LED current | ≤3 mA IFT allows direct interfacing with 3.3 V logic outputs without series resistor recalibration |
| High isolation voltage | 500 Vrms BVS enables galvanic separation between controller-side logic and DUT-side analog/digital domains |
| VSON surface-mount package | 1.6 × 1.6 mm footprint saves PCB area in space-constrained probe card layouts and modular instrument designs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar photorelay applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLP3440(TP,F | Higher 60 V VOFF rating; 0.4 pF COFF; 25 Ω max RON | Better suited for higher-voltage tester rails (e.g., 48 V bias); slightly slower switching | Select when system requires >40 V blocking capability and can tolerate +5 µs tON/tOFF |
| PS8702-1-AX | SOIC-4 package; 30 V VOFF; 0.25 pF COFF; 1.2 V VF | Larger footprint but lower forward voltage eases LED drive design; lower isolation (3750 Vrms) | Prefer when board space permits SOIC and higher isolation is not required for functional safety |
Compared with TLP3442(TP,F, the TLP3440(TP,F offers enhanced voltage margin at the cost of speed and on-resistance, while PS8702-1-AX trades miniaturization for easier LED biasing and higher isolation-making TLP3442(TP,F optimal for space-constrained, high-frequency ATE channel switching where 40 V and 0.3 pF are design-critical.

FAQ
What is the maximum recommended operating temperature for the TLP3442(TP,F?
The TLP3442(TP,F has a specified operating temperature range of −40 °C to +110 °C, with recommended continuous operation up to +85 °C to maintain rated electrical characteristics including 100 mA ON-state current and 0.6 pF max COFF. Derating applies above 25 °C per absolute maximum ratings table-ION decreases by 1 mA/°C above 25 °C.
Does the TLP3442(TP,F require external current-limiting resistors for the LED input?
Yes-the TLP3442(TP,F LED must be driven with a series current-limiting resistor to constrain IF within 0.1–3 mA (trigger) and ≤30 mA (absolute max). At 3.3 V supply, a 1 kΩ resistor yields ~2.0 mA IF assuming 1.27 V VF, satisfying the ≤3 mA IFT requirement while staying within safe operating limits for continuous use.
How is the dual-drain configuration (Pins 3 and 4) implemented in the TLP3442(TP,F?
Pins 3 and 4 of the TLP3442(TP,F are internally shorted drain terminals of the photo-MOSFET, forming a single output node. This dual-pin layout reduces effective on-resistance and improves thermal dissipation-allowing both pins to be soldered to the same PCB copper pour to achieve the 15 Ω typical RON and support 100 mA continuous current without exceeding junction temperature limits.
Can the TLP3442(TP,F be used in AC signal switching applications?
No-the TLP3442(TP,F is a unidirectional, normally-open photorelay with MOSFET output architecture optimized for DC and pulsed digital signals only. It lacks body diode symmetry or bidirectional conduction capability; applying reverse polarity or AC voltage beyond its 40 V DC blocking rating risks permanent damage to the output MOSFET structure.
What is the moisture sensitivity level (MSL) and baking requirement for the TLP3442(TP,F?
The TLP3442(TP,F is packaged in moisture-proof tape-and-reel (TP type) with MSL Level 1 per J-STD-020. Unopened reels may be stored up to 24 months at ≤30 °C/90 %RH. After opening, assembly must occur within 168 hours at ≤30 °C/70 %RH; if humidity indicator shows ≥30 %, bake at 60 ±5 °C for 64–72 hours before use-baking permitted only once.
