The basic criteria for selecting a TVS diode is its breakdown voltage, power handling capability, and response time.

• The breakdown voltage should be higher than the maximum voltage that the circuit will experience.

• The power handling capability should be sufficient to handle the maximum transient power.

• The response time should be fast enough to clamp the transient voltage before it can damage the circuit.

• Other factors to...read more

BJT and MOSFET are two types of transistors. Avalanche breakdown is a phenomenon that occurs in both.

• BJT is a bipolar junction transistor that uses both electrons and holes for conduction while MOSFET is a metal-oxide-semiconductor field-effect transistor that uses only electrons.

• BJT has a higher gain and faster switching speed than MOSFET but is less efficient and generates more heat.

• Avalanche breakdown is a phenomeno...read more

SMT process involves placing surface mount components on PCB. Testing and checks include AOI, X-ray, ICT, and functional testing.

• Solder paste is applied to the PCB pads

• Components are placed on the solder paste using pick and place machines

• The PCB is then heated in a reflow oven to melt the solder paste and attach the components

• Automated Optical Inspection (AOI) is done to check for any defects in component placement an...read more

A UDS tool communicates through a diagnostic protocol and Autosar has four layers: Application, RTE, BSW, and MCAL.

• UDS tool communicates through a diagnostic protocol called Unified Diagnostic Services (UDS)

• Autosar has four layers: Application, Runtime Environment (RTE), Basic Software (BSW), and Microcontroller Abstraction Layer (MCAL)

• Application layer contains the software components that implement the application fu...read more

Recall activity and learnings from DG and DFMEA implementation

• Recall activity: XYZ product was recalled due to a safety issue identified during customer usage.

• Learnings from DG: Identified the need for improved communication between design and manufacturing teams to ensure proper implementation of design guidelines.

• Learnings from DFMEA: Discovered potential failure modes and their effects on product performance, leadin...read more

CAN protocol is used in Automotive 2W due to its reliability and efficiency. I have worked with LIN, FlexRay, and Ethernet protocols.

• CAN protocol is used in Automotive 2W due to its ability to handle large amounts of data and its error detection capabilities.

• LIN protocol is used for low-speed communication in automotive applications.

• FlexRay protocol is used for high-speed communication in automotive applications.

• Ethern...read more

The electrical system of 2W EV vehicles consists of a battery, motor, controller, and charging system.

• The battery provides power to the motor.

• The motor converts electrical energy into mechanical energy to drive the vehicle.

• The controller manages the flow of electricity between the battery and motor.

• The charging system recharges the battery when the vehicle is not in use.

• Other components include sensors, wiring, and fus...read more
