TVS (Transient Voltage Suppression) diodes, also known as "lightning arresters", are voltage-activated, unidirectional devices used to protect electronic circuits from voltage transients induced by lightning or from other sources such as electrostatic discharge. The TV15C161J-HF is a widely used transient-voltage-suppressor diode designed to protect sensitive electronic components from transient voltage faults. It is a unidirectional, low-capacitance, single-line protection device.

The TV15C161J-HF is designed with a metal-oxidesemiconductor (MOS) technology, which offers a high surge current capability with a low capacitance. The TV15C161J-HF offers a low-capacitance device of ESD protection - typically 0.7 pF for an 18V device - while boosting the peak pulse power dissipation up to 1500W. The device comprises of a MOS guard-ring structure with an embedded PN junction and integrated ESD protection technology.

The TV15C161J-HF is available in an 8-lead SOIC package, and is designed for use in a wide range of applications such as computers, monitors, set top boxes, DTV, and other digital consumer electronics, and Automotive. It also has a wide operating temperature range of -55 °C to 125 °C and is capable of providing ESD protection of up to ±30 kV Human Body Model (HBM).

The TV15C161J-HF operates on a two-stage principle, making it the ideal solution for protecting sensitive electronic components from transient voltage faults. In the first stage, the TV15C161J-HF is designed with a MOS capacitor structure, which offers a high surge current capability and a low capacitance. The MOS capacitor allows the voltage to be clamped effectively, absorbing excess current and dissipating it as heat, thus protecting the sensitive electronics. The second stage of protection is provided by the PN junction, which act as a short-circuit and redirects the current to ground, further protecting the sensitive electronics.

In addition, the TV15C161J-HF is widely used in high-end portable electronics, particularly applications that require power protection from transient high voltage events. The device also provides additional ESD protection up to ±25 kV Contact Discharge (CD) for added protection against transient voltage events.

Overall, the TV15C161J-HF is a widely used and highly effective transient voltage suppressor diode designed to protect sensitive electronics from voltage transients. With its two-stage protection system, the TV15E161J-HF is an ideal solution for devices requiring high surge current capability with low capacitance and a wide operating temperature range. The device is available in an 8-pin SOIC package, and provides ESD protection of up to ±25 kV CD and ±30 kV HBM.
