Transil or Transient Voltage Suppressor (TVS) diodes are a type of surge protection device used to protect circuits against high-voltage transients. A typical TVS combines the characteristics of a varistor and an MOV (Metal Oxide Varistor), hence the term MOV diode.

The B72530V1140S262 is one such device among the range of Transil’s TVS diodes and it provides wide-rangetransient overvoltage suppression for sensitive electronics areas such as power supplies, automotive electronics, communications and audio-video equipment.

Application Field:The B72530V1140S262 is a 70V avalanche diode that is specifically designed to protect electronic components from high-voltage transients, and is commonly used in automotive electronic control units, power supplies, communications equipment, and audio-video equipment.

Working Principle:The B72530V1140S262 is a rectangular diode with a typical rectifying characteristic; the anode (marked as +) being connected to the external power supply, while the cathode (marked as -) is connected to the protected area. When a positive voltage is applied to the anode, charge carriers are accelerated and/or multiplied within the avalanche region of the diode, thus creating a constant overvoltage protection. Once the voltage on the diode reaches the breaking point, the collector-base-junction will break down and the current will be evacuated inside the diode. This transient is limited by a series of internal resistors, thus limiting the current that can be drawn from the protected area, thus preserving the system.

The B72530V1140S262 has a resistive-type display, anode inserted, and a failsafe open-drain structure. This construction is designed to provide superior performance, lower power consumption, and longer lifetime. Additionally, it offers enhanced overvoltage protection with low-capacitance response and low EMI/RFI emissions.

The B72530V1140S262 is RoHS compliant, making it ideal for today’s green energy and sensitive electronics application. It also offers various features such as low temperature dependence, surge capability up to 8A, faster response time, no latch-up behaviour, and excellent long-term reliability.

In conclusion, the B72530V1140S262 is a highly versatile TVS diode that provides wide-range transient overvoltage protection for sensitive electronics areas such as power supplies, automotive electronics, communications, and audio-video equipment. Thanks to its superior performance and low power consumption, it is suitable for a wide range of applications.
