Diodes
A diode is a two-terminal electronic component that conducts current primarily in one direction. It is made up of a semiconductor material and has the ability to allow current to pass through it in one direction while blocking current in the opposite direction. Diodes have a wide range of use cases, including rectification, voltage regulation, signal detection, and power management. They are essential components in electronic circuits and can be found in a variety of electronic devices, including computers, smartphones, and appliances. Flux.ai is the world's largest community-driven public library of diodes, with a vast collection of footprints, symbols, datasheets, and simulation models.

IC SURGE STOPPER 2.7V~23V VQFN-10-HR(2x2) The TPS25947xx family of eFuses is a highly integrated circuit protection and power management solution in a small package. The devices provide multiple protection modes using very few external components and are a robust defense against overloads, short-circuits, voltage surges, reverse polarity and excessive inrush current. With integrated back-to-back FETs, reverse current flow from output to input is blocked at all times, making the devices an excellent choice for power MUX/ORing applications as well as systems which need load side energy hold up storage in case input power supply fails. The devices use linear ORing based scheme to establish an almost zero DC reverse current and emulate ideal diode behavior with minimum forward voltage drop and power dissipation. Output slew rate and inrush current can be adjusted using an external capacitor. Loads are protected from input overvoltage conditions either by clamping the output to a safe fixed maximum voltage (pin selectable), or by cutting off the output if input exceeds an adjustable overvoltage threshold. The devices respond to output overload by actively limiting the current or breaking the circuit. The output current limit threshold as well as the transient overcurrent blanking timer are user adjustable. The current limit control pin also functions as an analog load current monitor. The devices are available in a 2mm × 2mm, 10- pin HotRod™ QFN package for improved thermal performance and reduced system footprint. The devices are characterized for operation over a junction temperature range from –40°C to +125°C. • Wide operating input voltage range: 2.7V to 23V – 28V absolute maximum – Withstands negative voltages up to –15V • Integrated back-to-back FETs with low onresistance: RON = 28.3mΩ (typical) • Ideal diode operation with true reverse-current blocking • Fast overvoltage protection – Overvoltage clamp (OVC) with pin-selectable threshold (3.8V, 5.7V, 13.8V) and 5μs (typical) response time OR – Adjustable overvoltage lockout (OVLO) with 1.2μs (typical) response time • Overcurrent protection with load current monitor output (ILM) – Active current limit OR circuit-breaker options – Adjustable threshold (ILIM) 0.5A to 6A • ±10% accuracy for ILIM > 1A – Adjustable transient blanking timer (ITIMER) to allow peak currents up to 2 × ILIM – Output load current monitor accuracy: ±6% (IOUT ≥ 1A) • Fast-trip response for short-circuit protection – 500ns (typical) response time – Adjustable (2 × ILIM) and fixed thresholds • Active high enable input with adjustable undervoltage lockout threshold (UVLO) • Adjustable output slew rate control (dVdt) • Overtemperature protection • Digital outputs – Priority power MUX control (AUXOFF) and fault indication (FLT) or – Power Good indication (PG) with adjustable threshold (PGTH) • UL 2367 recognition – File No. E339631 – RILM ≥ 750Ω • IEC 62368-1 CB certified • Small footprint: QFN 2mm × 2mm, 0.45mm pitch #CommonPartsLibrary #IntegratedCircuit #PowerManagement
