Diodes are a type of electronic component with two terminals that play a fundamental role in the operation of myriad electronic circuits. They are broadly divided into single and multiple, the latter being found either in series or in parallel. The family of single diodes comprises several compound semiconductor materials, including silicon (Si), germanium (Ge), selenium (Se), and gallium arsenide (GaAs).

Among the most commonly used single semiconductor diodes are the BAT85 and 113. They are uniformly rated at 0.4 Watts and normally block currents of up to 500 Volts. The BAT85 and 113 are both silicon diodes with numerous features, such as a breakover voltage of 88 to 92 Volts and a maximum reverse current of 5 micro Amps.

The BAT85 and 113 have various applications. Automotive electronics are among the principal applications, as they are mainly used as voltage-clamping devices in Engine Control Modules and Sensors, including spark voltage pickups, knock-sensors, fuel pressure controllers and idle speed controllers. Other application fields include power sources, linear regulators, and solar cell-power generators.

These diodes have certain working principles. TheBAT85 and 113diodes are mostly used with a forward bias as part of a low-resistance circuit configuration, such that the positive voltage on the anode side is always greater than, or equal to, the negative voltage on the cathode side. Under these conditions, electrons are able to flow from the anode to the cathode, thus allowing an electric current to be conducted.

The reverse bias operation of the BAT85 and 113 relies on the diode’s built-in junction potential properties. This subtle voltage difference across the two terminals prevents any current from entering in the reverse bias direction. The junction potential of the diodes basically prevents any reverse current from flowing.

TheBAT85 and 113are among the most versatile and reliable single diodes, featuring an ideal choice of wide and constant forward current. As such, they can be used in various types of circuits and systems, allowing the widespread use of low-cost low-voltage AC/DC converters and power supplies.
