After the first models of the CC series – all normally open (NO) relays in TSON packages – had been very well received in the market, Panasonic Industry has followed up with the corresponding normally closed (NC) relay, now part of its ultra-miniature PhotoMOS® range.

“We are pretty certain that our 1FormB TSON type is currently matchless throughout the industry – as far as size and current consumption are concerned”, states Michael Renner from Panasonic Industry Europe. “With just an eighth of a SOP4 package’s size and 1/10 of its current consumption, our latest member in the PhotoMOS® family considerably contributes to space and energy savings in application designs that keep getting smaller and smaller, for example telecommunication, measurement or medical equipment.”

TSON PhotoMOS® relays faeture galvanic isolation between input and output that is not optical but capacitive. This not only enables a significantly smaller design but also offers considerable advantages in the temperature range, the drive power and the switching times. As a result, the new TSON relays are ideal for use in working conditions with up to +105°C ambient temperature. The current required for control is typically as low as 0.04 mA and the input can be operated directly with voltages of typically 3.3 Vin. Consequently, for this voltage-driven type a series resistor – as usually required by conventional PhotoMOS® types – is no longer necessary.

With the CC series’ 1FormB type, Panasonic Industry completes its range of ultra-compact TSON variants for now – and once again takes a step forward into the post-electromechanical era of modern and compact relay technology.

Key features of the CC series include:

  1. Ultra-small TSON package
  2. 1FormA and 1FormB types available
  3. Switching capacity of 1FormB type: 60-V, 0.15-A
  4. Low On resistance
  5. Low output capacitance
  6. Voltage-sensitive input
  7. High temperature range up to +105°C
  8. Linear output characteristics
  9. High reliability and unlimited switching cycles
  10. AC/DC switching
