Fast Photorelays Boost Efficiency in Semiconductor Test

Toshiba Electronics Europe GmbH has recently unveiled the TLP3414S and TLP3431S photorelays, designed to enhance semiconductor testing processes significantly. These new photorelays boast high-speed turn-on times that are up to 62% faster than their predecessors, all while maintaining top-notch performance levels. Additionally, the compact package of the relays is 20% smaller than previous models, resulting in space-saving benefits for PCB layouts.

Specifically tailored for pin electronics applications in semiconductor testers, the TLP3414S and TLP3431S are perfect for accurately and swiftly measuring devices under test (DUT) while efficiently switching signals. The enhanced optical coupling efficiency of these photorelays is made possible by advancements in infrared LED performance and the optimized design of the photodiode arrays, enabling turn-on times of up to 150μs.

Compared to their predecessors, the TLP3414S and TLP3431S exhibit remarkable performance improvements, with the turn-on time of the TLP3414S being 50% faster and the TLP3431S achieving a speed improvement of approximately 62%. These quicker turn-on times do not compromise the devices' signal attenuation capabilities, with the TLP3414S boasting an ON-state resistance of 3Ω maximum and the TLP3431S featuring 1.2Ω maximum resistance.

Moreover, both models have an output capacitance of typically 6.5pF, crucial for minimizing high-frequency signal leakage when the output is inactive. The TLP3414S is rated at 40-V/250-mA for OFF-state output terminal voltage and ON-state current, while the TLP3431S features a rating of 20-V/450-mA, ensuring reliable performance under varying conditions.

Utilizing Toshiba's latest S-VSON4T package, measuring just 1.45- × 2.0- × 1.3-mm, the TLP3414S and TLP3431S contribute to equipment miniaturization by reducing the mounting area by approximately 20% compared to previous Toshiba packages. These advancements in photorelay technology are set to revolutionize semiconductor testing processes, offering improved efficiency and performance for a wide range of applications.
