Diodes - Zener - Single

The 1SMB5931BT3G is a Zener Single Diode, found within the popular Surface Mount Diode (SMD) range by NXP Semiconductor. This diode is defined by its medium-power diameter of 3.6mm. Its size and power make it an ideal choice for applications that require a bit more power than many other commonly used SMDs.

Application Field

Given its size, the 1SMB5931BT3G is an attractive choice for medium-power applications that require a small form factor for their design. Examples include mobile phones, PDAs, and other devices where a compact but reliable power circuit is necessary. Because this diode requires little energy and can be mounted efficiently, it also makes a viable choice for automotive applications, such as lighting and engine control systems.

Working Principle

The 1SMB5931BT3G works through the same principle as any other Zener diode. A Zener diode is a type of diode that operates by allowing reverse current flow at its Cathode – Anode junction when a reverse voltage is applied. This working principle allows for the voltage to be clamped at its Zener voltage, allowing for stable and reliable voltage regulation.

This diode is also specified for two configurations, the P1 and P2, each specifying the maximum forward current that can be sustained. The P1 configuration can sustain a forward current of 100mA, while the P2 can sustain a maximum forward current of 300mA, making this device suitable for power output.

Conclusion

The 1SMB5931BT3G is a single Zener SMD diode, making it ideal for medium-power applications that require a small form factor. It is specified with two configurations, the P1 and P2, that have different maximum forward current tolerances. This diode works through the same basic principles as any other Zener diode and as such makes it an attractive option for applications needing a stable and reliable voltage regulator.
