Device Selection & Applications

Device Selection & Applications: Datasheets, Device Selection & Device Debugging, Automotive & EV Semiconductor Devices, Semiconductor Devices in Analog, Digital, Power & Communication Systems.

• Datasheets, Device Selection & Device Debugging — Choosing and troubleshooting real devices. Learn to read semiconductor datasheets (absolute maximum ratings, electrical characteristics and test conditions, typical curves, temperature range, package and thermal data, SOA, switching and capacitance curves, gate charge, reverse recovery, leakage, breakdown, reliability/qualification data) — never treating typical values as guaranteed; a systematic selection flow (voltage, current, power, frequency, switching speed, leakage, capacitance, temperature, package/thermal, SOA, cost, availability, reliability, qualification/automotive grade); and device-level debugging (shorts, opens, leakage, low gain, wrong threshold, breakdown, thermal runaway, switching loss, oscillation, unexpected capacitance, gate failure, ESD damage) with a structured workflow — with Python comparing three MOSFET candidates by loss, junction temperature (with R_DS(on) temperature iteration), gate power and price.
• Automotive & EV Semiconductor Devices — Semiconductors in vehicles. Learn automotive environmental and electrical challenges (−40 to 150 °C, load dump, reverse battery, cold crank, thermal cycling, vibration, EMI/EMC, ESD), AEC-Q qualification and functional-safety context (ISO 26262), device families — automotive MOSFETs and smart high-side switches, IGBTs, SiC and GaN, TVS and power diodes, Hall and current sensors, photodiodes, pressure and temperature sensors, battery-monitoring ICs, gate drivers and voltage regulators — and the EV powertrain: traction inverter devices (Si IGBT vs SiC MOSFET), DC-DC converters, on-board chargers, BMS components, current/voltage/thermal sensing — with Python comparing drive-cycle inverter losses for Si IGBT and SiC and their effect on range, without presenting either as universally superior.
• Semiconductor Devices in Analog, Digital, Power & Communication Systems — Connecting device physics to systems. See how device properties become circuit behaviour: in analog circuits (g_m, r_o, matching, noise and temperature in amplifiers, current mirrors, differential pairs, references, op-amps, filters, oscillators, regulators and sensor interfaces), digital circuits (CMOS inverters and gates, noise margins, delay, dynamic and leakage power, fan-out, SRAM/DRAM/flash, processors), power systems (switch, diode and driver selection), and communication systems (LNAs, mixers, PAs, detectors, photodiodes, lasers, PIN switches, varactors, PLLs, HEMTs, HBTs) — with Python linking device parameters to circuit metrics.
