What Is a Low Leakage Small Signal Diode?

A low leakage small signal diode is a low-current semiconductor device engineered to minimize reverse current while switching, steering, clamping, or protecting sensitive signals. It helps preserve accuracy in battery-powered, high-impedance, analog, and fast digital circuits by reducing unwanted current flow, voltage drift, standby drain, and measurement error. Key Takeaways A low leakage small signal … Read more

What Are Discrete Power Devices and Why Do They Matter?

A discrete power device is a standalone semiconductor that performs one dominant power function — switching current, converting AC to DC, blocking reverse current, or clamping abnormal voltage. Rectifier diodes, MOSFETs, IGBTs, thyristors, TVS and ESD diodes, Zener diodes, and silicon-carbide devices all belong to this class. They matter because the chosen device often decides … Read more

What Are SMPS Components and Their Functions?

An SMPS, or switched-mode power supply, converts electrical power efficiently using a coordinated set of parts that rectify, switch, transform, filter, protect, and regulate voltage. The main components include the input filter, rectifier, bulk capacitor, switching transistor, controller IC, transformer or inductor, output rectifier, output filter, feedback network, and protection parts. Understanding each function helps … Read more

How to Select Rectifier Diodes for SMPS?

Choosing the right rectifier diode for SMPS means matching voltage, current, recovery speed, thermal limits, and package style to the converter’s operating conditions. In high-frequency switching supplies, the wrong diode can cause extra loss, overheating, EMI, or failure. The best choice depends on topology, switching frequency, output current, and efficiency goals. Key Takeaways Choosing the … Read more

How Do You Choose a MOSFET for a Switching Power Supply?

A MOSFET for a switching power supply must match the bus voltage, load current, switching frequency, and thermal limits. The best choice balances low RDS(on), low gate charge, adequate voltage margin, and package thermal performance. In SMPS designs, the right device improves efficiency, reduces heat, and increases reliability. Key Takeaways A MOSFET for a switching … Read more

How Do You Design an EMI Filter?

A switching power supply EMI filter design reduces conducted noise, improves EMC compliance, and protects the power line from switching spikes. The best design starts by identifying whether the noise is differential mode or common mode, then choosing the right LC, pi, or common-mode choke network, and finally validating the result with measurement and layout … Read more

Good-Ark MOSFET: A Practical Guide For B2B Semiconductor Sourcing

For power design teams, MOSFET selection is rarely just about voltage, current, or a low RDS(on)R_{DS(on)}RDS(on)​. Buyers also need package fit, documentation, qualification confidence, and application alignment, especially when the device will sit inside SMPS, PV inverter, automotive, or other power electronics systems. Key Takeaways For power design teams, MOSFET selection is rarely just about … Read more

SiC Semiconductor Selection: What B2B Buyers Should Verify Before Design-In

For engineers and sourcing teams evaluating silicon carbide-related power designs, the real challenge is not just finding a component label that looks right. It is confirming that the supplier, documentation, package format, qualification evidence, and application fit all line up before the project moves into validation or production. Key Takeaways For engineers and sourcing teams … Read more

Good-Ark Semiconductor: A Practical Guide to Discrete Device Sourcing for Power Electronics

In discrete semiconductor sourcing, the hard part is rarely finding a part number — it is proving that the part fits the circuit, the package, the compliance target, and the production plan without creating avoidable risk. For teams working on SMPS, automotive lighting, PV inverters, and other power-electronics designs, this guide walks through the sourcing … Read more
