Diodes are an important component of a variety of modern electronics, and Rectifiers are a type of diode that converts alternating current (AC) to direct current (DC). The HSM890G/TR13 is a single-phase, silicon-controlled rectifier designed for use in automotive applications. This device, when used in conjunction with a controller, is capable of producing highly efficient and reliable DC power. In this article, we will explore the application field, working principle and performance characteristics of the HSM890G/TR13.

Application Field of HSM890G/TR13

The HSM890G/TR13 rectifier is primarily designed for automotive applications, such as auxiliary power modules, engine start/stop applications, and trucking and towing systems. This is because the device has been extensively tested in the automotive environment and is suitable for such harsh environments. The rectifier also offers a wide range of features, such as improved power regulation, planar construction, and low thermal resistance.

Working Principle of HSM890G/TR13

The HSM890G/TR13 is a silicon-controlled rectifier (SCR) designed for use in automotive applications. This device uses a planar construction, which is composed of a combination of two or more rectifiers connected back-to-back. The silicon-controlled rectifier can be turned on or off depending on the input signal level and the voltage polarity. This allows for efficient control of the output current, which makes it ideal for automotive applications that require precise control of power.

When the SCR is off, the positive inlet terminal of the device is more negative than the negative inlet terminal. This creates a rectifying resistance in the device, which helps to control the output current. When an input signal is applied to the device, it will turn on and conduct current through the device. This current flow is controlled by the voltage polarity and the input signal level. This ensures that the device can provide a highly consistent and efficient output current.

Performance Characteristics of HSM890G/TR13

The HSM890G/TR13 is suitable for automotive applications due to its high performance characteristics. The rectifier\'s planar construction helps to make it highly reliable, with a maximum forward current rating of 130A and a peak forward surge current rating of 250A. This device also offers a low thermal resistance rating (less than 0.04-K/W) which helps to improve device reliability and its heat dissipation characteristics.

This rectifier device is also capable of operating at wide voltage ranges. It can operate within a voltage range of 10V to 800V, and can handle up to 400V reverse voltage. Furthermore, this device offers a fast response time for efficient power regulation, with a trigger turn-on time of 40μs max. and a trigger turn-off time of 60μs max.

Conclusion

The HSM890G/TR13 rectifier is a single-phase, silicon-controlled rectifier designed for use in automotive applications. This device has a planar construction which helps to make it highly reliable and offers a range of features, such as improved power regulation and low thermal resistance. The device also has a wide operating voltage range and offers fast response times for efficient power regulation. This makes the device suitable for a wide range of automotive applications.
