The SMBJ33CAHE3/5B is a Transient Voltage Suppressor Diode (TVS) device that is designed to protect electronic circuits and components from short-term voltage transients. Also known as “clamping diodes”, TVS devices provide protection against transient voltage surges by clamping the voltage between two levels, preventing it from exceeding a certain voltage. The SMBJ33CAHE3/5B is rated at 33 volts and designed to protect against electrostatic discharges (ESD) up to the human body model, as defined by IEC 6100-4-2 and EN 61000-4-2.

The SMBJ33CAHE3/5B is commonly used in applications where high-voltage spikes and ESD need to be suppressed, such as in USB ports, audio-video connectors, and high-speed data lines. It can also be used in automotive electronic systems, as well as in industrial applications where it is necessary to protect against voltage spikes. The device has a max power dissipation rating of 350 mW, and an operating temperature range of -55°C to +150°C.

The basic operation of the SMBJ33CAHE3/5B is as follows. It consists of two main components: a voltage clamp, and an ESD protection diode. The voltage clamp will limit the voltage across the diode to a certain level, in this case 33 volts. The ESD protection diode will then conduct any current above this voltage, thus suppressing any voltage transients. The voltage clamp also provides a quick response time to protect against short-term spikes.

The SMBJ33CAHE3/5B is a robust and reliable TVS diode. With its wide operating temperature range, it is suitable for use in a variety of applications. Its large surge current rating and low leakage current make it an ideal choice for protecting against ESD and voltage transients. Furthermore, the device is available in a range of packages, making it suitable for a range of industrial and automotive applications.

In summary, the SMBJ33CAHE3/5B is a Transient Voltage Suppressor Diode (TVS) device that is designed to protect electronic circuits and components from short-term voltage transients. It features a max voltage rating of 33 volts, a power dissipation rating of 350 mW, and an operating temperature range of -55°C to +150°C. The device is commonly used in applications where ESD and voltage spikes need to be suppressed, such as in USB ports, audio/video connectors, and high-speed data lines. It is a robust and reliable device that can provide reliable protection against transient voltages.
