Panasonic Launches Industry's Smallest*1 Semiconductor Device 'PhotoMOS' with Low Consumption Current

Applications
Small form factor measuring equipment requiring high density mounting.
Low consumption current wearable devices and battery operating equipment.
Measuring equipment requiring good high temperature performance.

 

Explanation of key features

1.  

Industry's Smallest *1 size. It will contribute to equipment downsizing.

Panasonic has applied our accumulated expertise with fine processing technology to equip our “PhotoMOS” with optical isolation[4], but now we have implemented capacitor coupled isolation. By adopting a capacitor coupled isolation driver[5] on the input side, it has been possible to overcome the obstacles to downsizing that were encountered with optical isolation. Using the industry’s smallest (1.8 × 1.95 × 0.8 mm) TSON[6] package, it is now possible to design smaller, higher performance probe cards and other measuring equipment.
2.

Low consumption current. It will contribute to more energy efficient equipment.

Panasonic’s new “PhotoMOS” CC type features proprietary, newly developed capacitor coupled isolation drivers. It achieves low consumption current operation, now 0.2mA, which our previous models with optical isolation could not manage. Greater energy efficiency also contributes to greater service lifetime for equipment that incorporates lower power consumption.
3.

Guaranteed performance at high temperature. It will contribute to equipment with higher performance under higher temperatures.

Along with the anticipated rising demand for automotive semiconductor devices, which have to work in harsh environments, users want probe cards and other measuring equipment to be capable of carrying out measurements in hot conditions. In previous products, optical isolation technology was a bar to high temperature operation, however, with their specially developed capacitor coupled isolation drivers, these new “PhotoMOS” are guaranteed to operate at up to 105°C and enable design of equipment with improved heat performance.
 

Notes

[1]   “PhotoMOS”
General term for a semiconductor-type relay that implements isolation of the input side and output side using a device to control current ON/OFF. A MOSFET (switching element) is used on the output side. PhotoMOS is a trade name belonging to Panasonic.
[2] Probe card
An electrical/mechanical part of equipment used during semiconductor manufacturing. Since devices have been getting faster, their capacity larger, and more complex, there has been demand for better performance and downsizing.
[3] Capacitor coupled isolation

A relay consisting of a semiconductor device with MOSFET on the output side, and use of a driver IC (comprising a driver circuit) on the input side.

[4] Optical isolation

A relay consisting of a semiconductor device with a MOSFET (switching element) on the output side, and use of an LED and light-receiving element on the input side.

[5] Capacitor coupled isolation driver
This refers to the input isolation element comprising an isolation capacitor and peripheral circuitry made using our unique technology. This enables downsizing, consumption current reduction, and better heat performance than the previous product that used an LED for optical isolation.
[6] TSON
Panasonic’s unique package type: short form for “Thin Small Outline No lead”.
