Toshiba unveils ‘TLP3475W’ – Industry’s smallest photorelay with enhanced signal transmission

In a strategic move, Toshiba Electronic Devices & Storage Corporation introduces the “TLP3475W,” a state-of-the-art photorelay encased in a compact WSON4 package. Pivotal for its ability to diminish insertion loss and restrain power attenuation in high-frequency signals, this latest product finds its optimal application in the pin electronics of semiconductor testers. These testers, characterized by their reliance on a multitude of relays and the necessity for high-speed signaling, can now benefit from this novel offering as volume shipments commence.

Optimized Design: A Game-Changer in Signal Transmission

The distinct advantage of Toshiba’s TLP3475W stems from its design optimization. By curtailing parasitic capacitance and inductance, this photorelay significantly reduces insertion loss, enhancing the transmission capacity of high-frequency signals up to 20GHz (typ.), which is approximately 1.5 times superior than its predecessor, the TLP3475S.

Compactness Meets Efficiency

In terms of form factor, the TLP3475W employs a diminutive, slender WSON4 package with a typical thickness of merely 0.8mm. This design achievement not only categorizes it as the industry’s smallest photorelay facilitating better high-frequency signal transmission but also renders it 40% shorter in stature compared to Toshiba’s ultra-compact S-VSON4T package. Such compactness allows for denser product placement on circuit boards, paving the way for enhanced measuring efficiency.

Looking Ahead: Toshiba’s Future Endeavors

With an unyielding commitment to technological advancement, Toshiba aspires to continually augment its product roster, catering to semiconductor testers that epitomize speed and multifunctionality. The TLP3475W, with its capabilities, symbolizes a significant stride in this direction.

Applications:

• Semiconductor testers (like high-speed memory and logic testers)
• Probe cards
• Measuring equipment

Features:

• Boasts the industry’s smallest WSON4 package with dimensions of 1.45mm×2.0mm (typ.), and t=0.8mm (typ.)
• Enhanced capability to transmit high-frequency signals, operating at f=20GHz (typ.)
• Incorporates a normally open function (1-Form-A)
