Confirming the Suitability of a Transistor in Actual Operation – Introduction
2022.04.15
In circuit design, transistors that can meet the requirements of the circuit are usually selected by referring to the specifications on the data sheet, and a prototype is made to confirm actual operation. In the prototyping, it is necessary to check the operation and phenomena that cannot be verified from the verification of the schematic on the desk, and to judge whether the selected transistor is appropriate or not. This chapter, entitled ” Confirming the Suitability of a Transistor in Actual Operation,” explains how to check whether the selected transistors are suitable in actual operation.
- ・Confirmation of the Chip Temperature
- ・Confirmation of Suitability in Actual Operation and Preparations
- ・Confirmation that Absolute Maximum Ratings are Satisfied
- ・Confirmation that Operation is within the SOA (Safe Operating Area)
- ・Confirmation that Operation is within the SOA Derated at the Actual Operating Temperature
- ・Confirmation that Average Power Consumption is within the Rated Power
- ・Summary
