TVS – Diodes are devices that provide surge protection for electronic circuits and components from transient voltages. The MAP5KE40A Transil is part of a series of transient voltage suppressor (TVS) materials specifically designed for automotive applications.

The MAP5KE40A components protect against damaging over-voltage transients and voltage increased due to ESD induced voltage conditions. It has a reverse standoff voltage of 40Volts and a power clamping capability of 5.0kW. The maximum clamping voltage of the MAP5KE40A is approximately 30Volts. The breakdown voltage of this component is 6V with 10µA rated current.

The MAP5KE40A is capable of handling ionizing radiation up to 10krad(Si) as defined in JESD22-A118-C. With a Unloaded Standoff Voltage of 40V and a Operating temperature range of -55°C to 125°C it is ideal for automotive applications. The bidirectional protection of the MAP5KE40A Transil can also protect both digital and analog components such as Hybrid IC, ASIC, FET, Relays, LCD, FPGA and microprocessor.

The working principle of the MAP5KE40A Transil is that it acts like a parasitic diode in a circuit when exposed to sudden voltage surges or over-voltage transients. Excessive current passes through the diode, allowing the transistor structure to limit the peak voltage seen at the protected pin or node. This prevents the breakdown of the device and ensures safe operation.

The MAP5KE40A Transil is suitable for a variety of automotive applications including powertrain, HVAC, safety, power accessories, audio, visual and communication. It can be used to protect automotive electronics from the damage caused by voltage spikes. It is also used as an over-voltage protection device in automotive battery packs. It is ideal for applications such as automotive fuel injection systems and other CAN-Bus systems for datalink protection.

The advantages of the MAP5KE40A Transil include low leakage current, high surge current handling capability, high noise immunity, low power dissipation, small size and weight, and low cost. It is also RoHS compliant and AEC-Q101 qualified.

In conclusion, the MAP5KE40A Transil is a beneficial and reliable component in the area of automotive electronic circuit protection for applications which require protection from over-voltage transients and ESD voltage conditions. It has a robust design, and can provide effective protection from damaging voltage conditions.
