Transistors are discrete semiconductors commonly used as an electrically controlled switch or as an amplifier in a range of analog and digital functions such as:

• Signal modulation
• Oscillators
• Voltage regulation
• Amplification
• Switching

One of the most common applications of transistors is as computer memory chips–such as solid-state multimedia storage devices–and microprocessors, which consist of millions of components embedded into a single integrated circuit. 

Whether you’re looking for field effect transistors (FETs) or bipolar transistors, MOSFETs or IGBTs, DEX can test, source, and deliver them, often in as little as 8-12 weeks. Leveraging our global network of suppliers–some of the largest in the world–DEX’s transistor sourcing and supply capabilities include:

• Bipolar (BJT)--(arrays; arrays, pre-biased; RF, single; and single, pre-biased)
• FETSs, MOSFETs (arrays, RF, and Single)
• IGBTs (arrays, modules, and single)
• JFETs
•  RF Transistors
• Special purpose

Top Industry Use Cases for Transistors

Transistors provide high voltage gain with a minimum supply voltage requirement, and their compact, simple circuit design allows them to operate quickly without a heating element. Voltage output remains constant despite changing temperatures, and their durable construction absent of any moving parts helps them last longer and better withstand mechanical shock and vibration. 

All of this makes transistors ideal for a range of use cases like:

• Industrial electronics
• Consumer electronics
• Transportation technology
• Defense and space industry
• Medical and biotechnology
• Telecommunications support
• Computer and peripheral equipment

DEX can help you select the right transistor for your circuit needs according to parameters such as:

• Current gain (higher current gains are better for amplification applications)
• Collector-emitter voltage (the amount of voltage that the transistor can handle)
• Type number (type numbers help us identify specifications and features)
• Collector-base voltage (maximum voltage that can be applied)
• Collector or peak current (maximum current it can accomodate before failure)
• Total power dissipation (how much power the device can withstand before potential failure)
• Collector-emitter saturation voltage (indication of voltage strength between the collector and the emitter)
