SA11CHE3/73 Datasheet/PDFTVS (Transient Voltage Suppressor) diodes are a type of semiconductor device that acts as a transient voltage protection component. They are primarily used to protect electronic circuits from high-voltage transients, such as electrical surges that can occur due to static charge build-up, lightning strikes, and the switching of inductive loads. Transient voltage suppression diodes are typically used to protect low voltage logic input circuits from voltage levels that exceed their normal voltage rating.
The SA11CHE3/73 is a TVS diode designed for use in consumer electronic applications such as digital cameras, GPS systems, PDAs, mobile phones, and portable electronic devices. It is designed to protect low voltage circuits from sudden high voltage transients, such as those caused by ESD (electrostatic discharge). The diode is designed to clamp the voltage level at 7.3 V, thus limiting the current which can flow through the circuit, and preventing any damage to the underlying electronics. The device features a low capacitance of 0.9pF and a low reverse leakage current of 50nA at junction temperatures from 10 to 125°C.
In operation, the TVS diode acts as a closed switch, allowing currents to flow freely when the input voltages remain under the threshold voltage. When the input voltage exceeds the specified threshold, the diode acts as an open switch, preventing current from flowing and protecting the underlying electronics from damage. The diode has a rated voltage of 10 V and can withstand transients up to 16V. The diode can be used in series with other components such as snubbers and capacitors to provide additional protection against high voltage transients.
The SA11CHE3/73 is designed to protect sensitive electronics from transient voltages up to 16V. It is a three-pin device which can be used for both unidirectional and bidirectional protection. The device is designed for surface mounting, with a 0.5 mm pitch and UL 94V1 flammability rating. The device has been tested and approved by Underwriters Laboratories for voltage transient suppressor application. The device is also compliant with the RoHS directive, and is free of lead and other hazardous materials.
In summary, the SA11CHE3/73 is a TVS diode designed for use in consumer electronics to protect against high voltage transients. It has a rated voltage of 10V, a low capacitance of 0.9pF, and a low reverse leakage current of 50nA. The device is designed for surface mounting applications, and features a 0.5 mm pitch and UL 94V1 flammability rating. The device has been tested and approved for voltage transient suppressor application, and is compliant with the RoHS directive.
