Stable Protection:This TVS diode features a 500W peak pulse power and 18A peak pulse current capacity, which can rapidly absorb transient surge currents. It effectively clamps the maximum voltage at 26V to prevent 3.3V low-voltage circuits from being damaged by instantaneous overvoltage shocks.
Low Capacitance:It maintains a low parasitic capacitance of 101pF at 1MHz, bringing negligible impact on high-speed signal transmission. The low-capacitance design ensures signal integrity without causing signal attenuation or delay in high-frequency circuit systems.
Ultra-Wide Temp:It supports an ultra-wide operating temperature range from -65°C to 150°C, adapting to extreme low-temperature and high-temperature working environments.It can maintain stable circuit protection performance in harsh industrial, outdoor and vehicle working conditions.
Compact Size:Adopting SC-76 and SOD-323 surface-mount packages, the component features ultra-small size and lightweight characteristics. It is suitable for highly integrated and miniaturized electronic devices with limited PCB layout space.
Precise Voltage:With a 3.3V maximum reverse standoff voltage and 5.8V minimum breakdown voltage, it matches standard 3.3V power supply circuits precisely. It avoids normal circuit voltage interference while achieving timely overvoltage breakdown protection.
USB Interface:Applied to the USB 2.0 and 3.0 interfaces of desktop computers and mobile chargers to protect internal control circuits. It absorbs static electricity and surge voltage generated by plugging and unplugging USB devices, avoiding interface chip burnout.
Audio Circuit:Used in the audio signal circuits of Bluetooth headsets and portable speakers. Its low-capacitance design protects sensitive audio chips without distorting sound signals, ensuring clear and stable audio output.
Sensor Module:Deployed on 3.3V power supply circuits of temperature and humidity sensors and photoelectric sensors for industrial equipment. It resists transient voltage fluctuations in industrial environments and guarantees continuous and accurate sensor data collection.
Vehicle Device:Installed in vehicle-mounted dash cameras and car Bluetooth modules. It adapts to the drastic temperature changes inside vehicles and suppresses voltage surges caused by vehicle startup and ignition to protect on-board electronic components.
Smart Wearable:Applied in smart watches and fitness bracelets with miniaturized circuits. The small-size package fits the compact internal space of wearable devices and provides reliable ESD protection for internal low-voltage control chips.
PESD3V3L1BA-QX is a high-performance miniaturized TVS diode tailored for 3.3V low-voltage circuits, with outstanding surge resistance and wide temperature adaptability. Although discontinued on DigiKey, it still serves as a reliable circuit protection solution for various traditional miniaturized electronic devices.
