Thyristors - SCRs - Modules

T1851N60TOHXPSA1 is a series of silicon controlled rectikes (SCRs) in a three lead surface mount package designed to suit a wide range of switching and phase angle controled applications. It supports high temperature operation up to 175°C, excellent surge strength capability up to 10KA, and high off-state voltage blocking up to 600V. T1851N60TOHXPSA1 is qualified to JEDEC standards, and is suited for use in the most adverse automotive environments.

Application Field

T1851N60TOHXPSA1 is suitable for many kinds of electronic systems, such as DC relays, starter system and other applications that call for switching in harsh environments. Due to its low thermal resistance, excellent surge strength capability and high off-state voltage blocking capability, T1851N60TOHXPSA1 provides reliable switching performance. In addition, its small size, light weight, and low profile make it a good choice for space-constrained applications.

Working Principle

T1851N60TOHXPSA1 works by conducting current when it is forward-biased and applying a higher voltage to its gate electrode. The higher voltage on its gate electrode polarizes its semiconductor material and creates a low-resistance path between its main contacts that allows current to flow. When no gate voltage is present, the device is off and its main contacts are in an open state. It is easy to control because it can be turned on and off simply by controlling the gate voltage.

Conclusion

T1851N60TOHXPSA1 provides an excellent choice for high-temperature applications and offers high surge strength capability and reliable switching performance. It is suitable for many kinds of electronic systems due to its low thermal resistance, excellent surge strength capability and high off-state voltage blocking capability.
