Toshiba Semiconductor and Storage TLP3341(TP15,F)

Overview

TLP3341(TP15,F) from Toshiba Electronic Devices & Storage Corporation is a normally-open photorelay in a 4-pin USOP-4 (11-2C1S) package, integrating an infrared LED optically coupled to a photo MOSFET. It delivers 40 V OFF-state voltage, 140 mA max ON-state current, 7 Ω typical ON-resistance, and ultra-low 0.7 pF typical OFF-capacitance-enabling high-frequency signal switching in automated test equipment.

For engineers reviewing the TLP3341(TP15,F) datasheet, TLP3341(TP15,F) pinout, TLP3341(TP15,F) application, or TLP3341(TP15,F) equivalent, key selection criteria include low COFF for RF path integrity, guaranteed IFT ≤ 3 mA for low-drive logic compatibility, isolation voltage ≥1000 Vrms for safety-critical tester interfaces, and USOP-4 footprint constraints in dense ATE PCB layouts.

Technical Context

The TLP3341(TP15,F) implements a single-pole, normally-open (1-Form-A) solid-state relay architecture with optical coupling between GaAs LED and silicon photo MOSFET. Its internal structure treats Pins 1–2 as a single anode–cathode pair and Pins 3–4 as a common drain output terminal-functioning as a two-terminal switch with galvanic isolation.

Designed for high-speed digital test instrumentation, it achieves 40 µs typical turn-on and 140 µs typical turn-off times under RL = 200 Ω, VDD = 20 V, IF = 5 mA conditions. The 0.7 pF COFF and 0.4 pF input-to-output capacitance minimize crosstalk and preserve signal edge fidelity up to RF measurement bands.

FAQ

What is the maximum recommended operating temperature for the TLP3341(TP15,F)?

The TLP3341(TP15,F) has a specified operating temperature range of −40 °C to +85 °C. This range is validated for continuous operation under recommended conditions including IF ≤ 20 mA and ION ≤ 140 mA. Exceeding +85 °C ambient may degrade isolation resistance and increase COFF, directly impacting reliability in high-density ATE chassis. Derating guidelines per Toshiba Semiconductor Reliability Handbook apply above 65 °C.

Does the TLP3341(TP15,F) support bidirectional signal switching?

No, the TLP3341(TP15,F) is a unidirectional, normally-open photorelay with asymmetrical MOSFET structure. Its internal photo MOSFET is optimized for source-grounded, drain-switched operation-supporting current flow only from Drain (Pins 3/4) to system ground. Bidirectional AC or RF signal routing requires external circuitry or alternative devices such as dual-MOSFET photorelays.

What is the minimum trigger LED current required to fully turn on the TLP3341(TP15,F)?

The TLP3341(TP15,F) guarantees full conduction (RON ≤ 10 Ω) with a trigger LED current (IFT) of ≤3 mA at Ta = 25 °C. At elevated temperatures, IFT increases-reaching up to 10 mA at +85 °C per Fig. 12.1.6. Designers must ensure driver capability meets worst-case IFT across the full operating temperature range to maintain reliable switching in production ATE environments.

Can the TLP3341(TP15,F) replace mechanical relays in RF test fixtures?

Yes-the TLP3341(TP15,F) replaces electromechanical relays in RF test fixtures where bandwidth, lifetime, and actuation speed are critical. With 0.7 pF COFF and 40 µs tON, it supports signal integrity up to 1 GHz and enables >10,000 switching cycles per second-far exceeding mechanical relay limits. However, its 40 V VOFF restricts use to low-voltage RF signal paths, not high-power RF amplifiers.

Is the TLP3341(TP15,F) RoHS compliant?

Yes, the TLP3341(TP15,F) complies with EU RoHS Directive 2011/65/EU. Toshiba confirms lead-free terminations and absence of restricted substances per its environmental compliance documentation. For full material declarations and exemption status, refer to Toshiba's official product page or contact their environmental affairs department directly-Aetrix Electronics sources only RoHS-compliant lots of the TLP3341(TP15,F).
