TVS - Diodes

Transient Voltage Suppression (TVS) diodes, otherwise known as unidirectional surge protection devices, are primarily used to protect components, such as circuit boards, from over-voltage conditions due to external lightning strikes or other transient electrostatic surges. TVS diodes, as the name suggests, also provide voltage and current limiting functions, and will turn on when the voltage level exceeds the breakdown voltage level of the diode.

30KPA28CA-B application field and working principle

The 30KPA28CA-B is a TVS diode used to protect against transient voltage surges. It is a unidirectional diode designed for surface mount applications on PCBs, and is typically used to protect sensitive components from short circuit, open circuit, over-voltage and electrostatic surge conditions. As a voltage clamp, it works by absorbing and dissipating electrostatic surge energy until the current passes safely below the holding threshold.

The 30KPA28CA-B is designed to protect automotive and industrial circuits from transient overvoltage conditions. It is typically used in power condition circuits, MOSFET gate drives, low side switching regulators, actuator control circuits and signal isolation circuits. The 30KPA28CA-B diode can absorb over 2,000 watts of peak pulse power per line, and its reverse standoff voltage is 28 volts.

The 30KPA28CA-B also features an ultra-low operating voltage and low incremental surge resistance, making it extremely effective at clamping transient voltage and current spikes and limiting them to safe levels. This diode offers a low leakage current, high peak current ratings, and a high peak current capability. It also has a high surge current tolerance of up to 30 Amps, and operates at a temperature range of -55°C to +175°C.

The working principle behind the 30KPA28CA-B diode is simple: when a voltage spike occurs, it quickly turns on and diverts the high current to the ground, thereby clamping the overvoltage and limiting transient surge effects. In order to do this, the diode must be connected in series with the circuit that needs to be protected. When the diode reaches the breakdown voltage, it turns on, allowing the current to pass through the diode and be dissipated as heat.

The 30KPA28CA-B is a reliable and effective way to protect sensitive components from over-voltage transients. Its high surge current capability, low profile, and robust construction make it ideal for a variety of industrial and automotive applications. Additionally, due to its small size and surface-mount design, the 30KPA28CA-B is easy to incorporate into existing circuit designs.
