Toshiba Electronic today announced that the latest optical relays in the S-VSON4T package - "TLP3414S" and "TLP3431S" - have faster on-time than TOSHIBA's existing products. The off-state output voltage and on-state current ratings of the TLP3414S and TLP3431S are 40 V/250 mA and 20 V/450 mA, respectively.

By improving the light output of the infrared LED on the input side and optimizing the design of the photodetector (photodiode array), the new optical relay enables efficient optical coupling and reduces the maximum on-time to 150 μs. The TLP3414S 'on-time is approximately 50% shorter than TOSHIBA's existing TLP3414, and the TLP3431S' on-time is approximately 62% shorter than TOSHIBA's existing TLP3431.

In addition, when the output is turned on, the on-resistance of these two products affects signal attenuation (TLP3414S: Max. 3Ω, TLP3431S: Max. 1.2Ω); When the output is turned off, the output capacitance affects the leakage of the high frequency signal (typical value 6.5 pF for both products). The new product is comparable to TOSHIBA's existing products, ensuring stable signal transmission.

The new product is suitable for pin electronics applications in semiconductor test equipment to measure the device under test (DUT) with high accuracy and speed while switching the signal.

The compact S-VSON4T package reduces surface area by approximately 20% compared to the VSON4 package of TOSHIBA's existing products, helping to miniaturize semiconductor test equipment and other equipment.

TOSHIBA will continue to offer more high-performance products to meet the demand for higher performance and faster speeds in semiconductor test equipment.

Applications:

Semiconductor test equipment (high-speed memory test equipment, high-speed logic test equipment, etc.)

Probe card

Measuring equipment

Features:

High speed turn-on time: tON = 150μs (Max)

Low on-resistance:

TLP3414S RON = 3 Ω (maximum value)

TLP3431S RON = 1.2Ω (maximum value)

Small S-VSON4T package: 1.45mm × 2.0mm (typical), thickness = 1.3mm (typical)
