Transient Voltage Suppression (TVS) diodes are available in various shapes and sizes for applications ranging from low-voltage transients to high-voltage applications. The MAPLAD7.5KP40CAE3 is a unidirectional bi-directional TVS diode. It is designed for transient protection applications in automotive systems such as Vehicle Network Interface (VNI), On-Board Diagnostics (OBD) and Electronic Control Unit (ECU). This diode provides surge protection for data lines and industrial sensor systems.

MAPLAD7.5KP40CAE3 has a maximum reverse leakage current of 7.5 mA and it offers a maximum clamp voltage of 5.7 V. This device is suitable for various temperature ranges. It can operate from -40°C to +125°C case temperature range. It also features fast response time with no more than 0.5 ns for a 2/10Us pulse.

The MAPLAD7.5KP40CAE3 is a symmetrical/bidirectional TVS diode having a common cathode connection. This diode provides bi-directional protection by allowing current to flow in either direction. It is designed to clamp the transient voltage across both pins and dissipate the incoming surge energy.

The working principle of the MAPLAD7.5KP40CAE3 is similar to other TVS diodes. When the diode is exposed to a voltage surge, the diode conducts and clamps the voltage level from reaching the sensitive components, protecting them from harm. The clamping voltage of the diode is determined by taking the product of the breakdown voltage, BV, and the avalanche multiplication factor (AMF).

The MAPLAD7.5KP40CAE3 TVS diode is used for transient voltage protection in automotive applications, such as ECU, VNI, and OBD. It is also well suited for industrial sensor systems and data line protection. The device features fast response time and wide operating temperature range. It is capable of clamping up to 5.7V peak voltage in either direction. This device is also highly reliable, making it ideal for surge protection applications.
