Mixed Technology Transient Voltage Suppressors (TVS) are semiconductor devices designed to protect sensitive electronic components from electrical transients, resulting from overvoltage and ESD events caused by lightning, load switching, and inductive switching. The BPHA24D24LV is a low capacitance diode array, designed with a unidirectional and bidirectional configurations, and is ideal for high-speed LAN data and high-speed signal applications. This diode array offers a wide range of features, including a high clamping capability, low dynamic and static capacitance, and a low forward voltage. With the BPHA24D24LV, transient voltages can be effectively clamped in a nanosecond time-frame to a safe maximum level, and power and signal are protected.

The BPHA24D24LV is an integrated circuit (IC), comprised of three silicon diodes with an integrated ESD protection diode in each of the three lines. The advantages of this IC are the low capacitance of each line, combined with the high ESD tolerance. At a maximum operating voltage of 24V, the capacitor and ESD protection circuit can be used to protect sensitive electronic components across a wide range of applications.

The BPHA24D24LV works by providing a low-impedance path for transient voltage spikes, and in the event of an ESD strike, the diode array acts as a voltage clamp to ensure a safe, limited maximum voltage level. The device features a high breakdown voltage, typically around 24 volts, and is designed to clamp the voltage across the protected device to this level. The diode array is composed of two bidirectional back-to-back Zener diodes and one unidirectional protective diode, connected in series. The current-limiting effect of the diodes ensures that the maximum level of voltage is kept in check, even during overvoltage and ESD events.

The BPHA24D24LV is designed for high-speed networks, LANs, and other applications where fast current-limiting is required. It offers low clamping voltage, low power dissipation, and high surge capability. It also features a low capacitance of 1.1pF (typical), which is advantageous when dealing with data rate up to 10Gb/s.

The BPHA24D24LV is suitable for use in a variety of applications, including automotive, industrial, communications, consumer electronics, and medical. It can be used in automotive LED headlight systems, for example, to protect against reverse ESD strikes from capacitive or inductive sources. In industrial applications, the BPHA24D24LV can be used to protect sensitive electronic devices from voltage surges caused by welding and lightning. In televisions, it can provide an effective barrier against overvoltage and ESD events that would otherwise damage sensitive components.

The BPHA24D24LV is a formidable Mixed Technology Transient Voltage Suppressor, providing a low-cost, effective way to protect sensitive electronic components from overvoltage and ESD events. The device offers a wide range of features, including low forward voltage, low capacitance, and high ESD tolerance, combined with a high clamping capability and a low dynamic and static capacitance. When used in a variety of applications—automotive, industrial, consumer electronics, and medical—the BPHA24D24LV can provide effective voltage clamping to ensure that power and signal are protected.
