PhotoMOS for Automotive Applications

PhotoMOS SSR Selection Guide Download

1. Before Selecting PhotoMOS for Automotive Applications

Some changes in specification parameters are needed when PhotoMOS® are used in certain automotive applications.
Automotive grade PhotoMOS® are generally used in automotive environment since stricter enhanced quality controls are needed.
The user is cautioned and asked to inquire with a Panasonic Corporation local sales representative before designing the products in such environments.

2. About Specification Reviews

Automotive applications require specification reviews. This is important and necessary in order to prevent performance, quality and reliability problems. The following parameters should be reviewed with a Panasonic Corporation local sales representative:

  • Targeted application
  • Targeted levels of quality and reliability
  • Circuits description of load level, driving methods, etc.
  • Service conditions
  • Influence at failure and failsafe concepts, etc.

3. About Derating Design

Derating is essential in any reliable design and a significant factor in consideration of product life. Sufficient derating is needed against maximum rating when designing a system.
It is recommended using a derated voltage of 40% (or less) of absolute maximum load voltage rating, and 50% (or less) of absolute maximum load current ratings.
Devices should be examined using a measurement equipment.
Derated voltages must be considered according to operating and environmental conditions the device will be subjected to.
In case of automotive applications, more allowance should be given to maximum ratings and installation of safety measures (i.e. use of double circuits).
Misuse of the products listed in this document shall be made at the users’ own risk.
