TVS (Transient Voltage Suppressors, or Transient Voltage Surge Suppressors) diodes are a type of solid-state device used to protect electronic components and systems from voltage spikes. The 30KPA48A-B is a diode specifically designed to protect against broad-band high-energy voltage spikes. It is designed to clamp high-voltage transients to acceptable levels and dissipate transient energy that can cause damage to components.

The 30KPA48A-B is designed to work in a variety of applications, from telecommunications to consumer electronics. It is ideal for applications that require a low-cost solution for protecting sensitive electronics from high-frequency and high-energy overshoot. It is available in both surface-mount and through-hole packages and can be used as an ESD (electrostatic discharge) protection device on high-capacitance lines.

The 30KPA48A-B has an operational range of 5.5 V to 450V, a peak pulse power rating of 60W (10/1000 us) and a peak pulse current rating of 800A (8/20 us). It is rated for a working frequency range of 9kHz to 10GHz and is designed to clamp voltages to 5.5 V.

The 30KPA48A-B is designed to operate in two stages. The first stage is an avalanche breakdown that acts as a voltage clamp, limiting the peak voltage to the breakdown voltage. The second stage is a zener breakdown that further controls the voltage level. This two-stage operation allows the 30KPA48A-B to have superior spike protection performance over a wide voltage range.

The 30KPA48A-B is a robust device, capable of decreasing the risetime of voltage overshoots while maintaining low capacitance. It is also designed to reduce signal crosstalk between power or signal lines and ground. This makes it well suited for use in high-speed data communication applications, such as Ethernet or the Universal Serial Bus (USB).

In addition, the 30KPA48A-B is designed to operate in reverse polarity, allowing it to protect components in a wide range of environments. It is designed to self-restore to its original operational state and has full-time ESD protection. It is also designed with low power electronic circuits in mind, making it ideal for applications such as lithium-ion battery storage.

The 30KPA48A-B is an ideal choice for applications requiring strong surge protection and wide-range voltage clamping. It is a robust, cost-effective solution for protecting sensitive electronic components from high-energy voltage transients and ESD events.
