Optocouplers are latch-up and oscillation free

Optocouplers are latch-up and oscillation free
A series of 1MBd high speed optocouplers featuring an open collector transistor output with Schmitt-Trigger functionality for easy integration into digital systems have been released by Vishay. The VOH1016A series devices provide a low typical turn-on threshold current of 0.65 mA and maximum supply current of 1.0 mA, and are designed for programmable logic controllers, serial data communication and bus systems, and switch mode power supplies.

Optocoupler enables 30% saving on PCB real estate

Optocoupler enables 30% saving on PCB real estate
The first AEC-Q101 qualified, phototransistor optocoupler introduced by Vishay is now available at TTI. This newly-launched device, the VOMA617A, combines a high current transfer ratio (CTR) of 50% to 600% with low 5mA forward current. Supplied in a compact SOP-4 package, the new device offers the major advantage of a 30% saving on PCB real-estate when compared to a DIP-4 package.

IC photocouplers provide option for wide leadform

IC photocouplers provide option for wide leadform
With a new wide leadform package type SO6L(LF4), Toshiba Electronics Europe has expanded its line-up of SO6L IC photocouplers. The wide leadform option is available for three high-speed IC photocouplers and five IGBT/MOSFET driver photocouplers. The new photocouplers can be directly mounted on PCB pads intended for SDIP6(F type) products. The SO6L(LF4)’s 2.3mm (max.) low profile package offers a 45% height reduction over SDIP6(F Type) and allows use in height-critical applications, such as mounting on the underside of PCBs.

High current photorelay range expands with 60 and 100V products

High current photorelay range expands with 60 and 100V products
Two additions have been added to Toshiba Electronics Europe's line-up of photorelays; the 60V TLP3407S and the 100V TLP3409S. These devices are packaged in S-VSON4, the 2.00x1.45mm package with what it claims to be the industry's smallest mounting area. The new products realise high voltages while retaining the features of the existing TLP3406S, which offers a 30V rating with large on-state current rating and small size.

Mid-voltage range photorelays offer increased reliability

Mid-voltage range photorelays offer increased reliability
Two new mid-voltage, high current photorelays have been launched by Toshiba Electronics Europe: the 100V TLP3823 with a 3A drive current, and the 200V TLP3825 with a 1.5A drive current. The new products will extend the range of large current photorelays to replace mechanical relays, alongside Toshiba’s current 60V, 5A TLP3547. Toshiba is supporting and promoting the accelerated replacement of mechanical relays by applying its latest trench MOSFET structure, 8th generation UMOS, to realise output currents exceeding 1A.
