ATV15C101JB-HF Circuit Protection

TVS or Transient Voltage Suppressors are devices used for protecting electronic circuits against transient voltage surges caused by electrostatic discharge (ESD), lightning, inductive switching and other surges. The ATV15C101JB-HF is just one type of TVS diode.

The ATV15C101JB-HF is a bidirectional TVS diode which, due to its current and voltage ratings, is suitable for high-frequency applications. It has an SOT-323 package and contains two parallel Zener diodes that have an operating voltage of 15V and a power dissipation of 500mW.

This diode is designed to absorb high-voltage, high-current transients and to protect sensitive electronic components from overvoltage and short-circuiting. Its low-capacitance design makes it suitable for use in high-speed, high-power applications and it has an operating temperature range of -55°C to 125°C.

The ATV15C101JB-HF also features reverse stand-off voltage (RoC), a breakdown voltage (BVdss) of 30V, an on-state resistance (Rds) of 0.45Ω, and an avalanche current rating of 8A (Tj=25°C). Its maximum peak pulse power is rated up to 1500W at a 1ms pulse width and a 10/1000μs waveform.

This diode also contains a protective element which dissipates excess current and suppresses any voltage overshoots. This protective element is designed to conduct large currents at high voltages and has the ability to act as a fusible link during severe surge events, eliminating the need for additional fusing.

In summary, the ATV15C101JB-HF is a bidirectional TVS diode which is suitable for high frequency applications and has a low capacitance design, making it suitable for use in high-speed, high-power applications. It is designed to absorb high-voltage, high-current transients and to protect sensitive electronic components from overvoltage and short-circuiting. The diode’s maximum peak pulse power is rated up to 1500W at a 1ms pulse width with a 10/1000μs waveform and it also contains a protective element to dissipate excess current and suppress voltage overshoots.
