Selection guides, application notes and design checks for rectifiers, Schottky diodes, TVS protection, MOSFETs, SiC and IGBTs — written for engineers and sourcing teams.
A USB ESD protection diode is a TVS device placed in parallel with USB data and power lines to clamp an electrostatic discharge transient within nanoseconds, before it can damage the controller or PHY downstream. The selection is dominated by two numbers that pull in opposite directions: the working voltage must sit above the bus, … Read more
A low clamping voltage TVS is a transient voltage suppressor designed to limit surge voltage to a lower peak during ESD, EFT, or inductive events. It protects sensitive electronics by turning on quickly, diverting surge current, and keeping the protected node within a safer voltage range. Proper selection depends on working voltage, surge energy, and … Read more
SMBJ TVS diodes are 600 W-class surface-mount transient voltage suppressors in an SMB (DO‑214AA) package, engineered to clamp lightning, ESD, and switching surges on DC rails and signal lines. They offer wide working voltages, fast response, and uni/bidirectional options, making them ideal for protecting power supplies, automotive modules, telecom, and industrial electronics when properly selected … Read more
An SMAJ TVS diode is a 400 W surface-mount transient voltage suppressor in an SMA (DO-214AC) package, designed to clamp ESD, inductive switching, and lightning-coupled surges on DC rails and I/O lines. It is the right choice when the worst-case surge fits within 400 W at the test waveform, the clamp voltage stays below your … Read more
An SMCJ TVS diode is a 1500 W surface‑mount transient voltage suppressor in an SMC (DO‑214AB) package, designed to clamp lightning, surge, and ESD events on power and signal lines. With fast response and wide voltage range, it is widely used in telecom, industrial, automotive, and power electronics equipment to protect sensitive semiconductor devices. Key … Read more
A bidirectional surge protection diode is a transient voltage suppressor (TVS) designed to clamp both positive and negative voltage spikes, typically on AC lines or differential data lines. It stays nearly invisible during normal operation, but when a surge exceeds its breakdown voltage, it switches on in nanoseconds, diverting surge current away from sensitive ICs … Read more
A unidirectional surge protection diode is a transient voltage suppressor (TVS) that clamps overvoltage spikes of a single polarity on a DC rail or single-ended signal line. Under normal operation it is effectively invisible — leakage current in the microamp range — but when a surge drives the line above its breakdown voltage, avalanche conduction … Read more
Automotive load dump is a high‑energy overvoltage surge that occurs when the battery is disconnected while the alternator is charging. TVS (Transient Voltage Suppressor) diodes clamp this surge within microseconds, absorbing its energy and limiting voltage seen by ECUs, sensors, and DC‑DC converters. Properly rated automotive TVS devices ensure reliable, standards‑compliant protection. Key Takeaways Automotive … Read more
In power electronics sourcing, a bridge rectifier is rarely selected as a standalone part. Engineers and purchasing teams need to balance thermal behavior, package height, board space, documentation, and application fit before approving a device for production. Good-Ark’s official site positions the company as a discrete semiconductor manufacturer with bridge rectifiers among its core product … Read more
