BFS20W Medium Frequency Transistors by Nexperia

Maximum collector-emitter voltage with the base open. This breakdown voltage defines the highest allowable voltage between collector and emitter without base connection. Engineers use it to ensure the transistor can withstand the supply voltage in the circuit. Check the datasheet for safe operating area.

Minimum DC current gain of a bipolar transistor. This value indicates the lowest guaranteed amplification at a specified collector current and voltage. Engineers compare it to ensure sufficient drive capability in switching and amplification circuits. Always verify against the datasheet's test conditions.

Maximum continuous collector current for a bipolar transistor. This is the highest current the transistor can handle without exceeding its thermal or reliability limits. Verify that your application's peak current stays below this rating to avoid overheating or damage.

Maximum total power dissipation of the component. This is the highest power the device can dissipate without exceeding its junction temperature. Engineers use it to design thermal management and ensure reliability. Exceeding this limit can cause failure. Verify with the ambient temperature rating.

Identifies the company that designed and produced the component. Buyers often filter by manufacturer to ensure brand reliability, quality standards, and supply chain consistency. Verify the manufacturer against the datasheet and official packaging to avoid counterfeit parts.

Identifies the physical package type or designator, such as SOIC, QFN, or DIP. This determines PCB footprint, thermal performance, and assembly compatibility. Verify the package matches your board layout and manufacturing capabilities. Check the datasheet for exact dimensions.

Physical dimensions of the component in millimeters. Essential for PCB layout and mechanical fit. Buyers and engineers compare size to ensure the part fits the design envelope. Always check the datasheet for exact dimensions and tolerances.

Specifies whether the component or signal has a defined positive and negative orientation, such as for diodes, electrolytic capacitors, or connectors. Incorrect polarity can cause failure or unsafe operation. Always check the datasheet and board markings before installation.

Minimum transition frequency of a transistor. This is the lowest guaranteed frequency at which the current gain falls to unity. It ensures the device will operate at the required speed in high-frequency circuits. Engineers use it to select components for RF and fast switching. Confirm with the datasheet's test conditions.

Maximum DC current gain of a bipolar transistor. This value indicates the highest possible amplification at a given operating point. Engineers consider it to avoid excessive gain that could cause instability or overdrive. It is essential for precise current control in analog circuits. Verify with the datasheet's test conditions.
