The BAS40-L,315 is a single diode rectifier, commonly used to direct current flow in one direction while facilitating superior power dissipation and a high surge current capability. This diode is available in a variety of package widths, allowing for varying tight spaces while still maximizing power density. It is designed to minimize voltage drop and minimize junctions temperature rise. Its low forward voltage drop and low switching losses provides fewer power dissipation losses, meaning it is more efficient than a traditional diode rectifier.

The BAS40-L,315 is a high power p−n junction rectifier, meaning it is a unidirectional diode which can be used to convert alternating current (AC) to direct current (DC). It is used in a variety of applications, from LED lighting to SMPS circuits, mostly due to its small package size, high power dissipation performance, low forward voltage drop, high surge current capability, and low switching losses.

At its most basic, the BAS40-L,315 works by allowing current to move only in one direction. It does this by converting AC to DC, and stopping it from constantly changing direction as it does in AC. Effectively, when current flows through the diode in a forward bias, it will allow it to travel in the same direction. However, if current attempts to travel in the opposite direction (a reverse bias), the diode will prevent the motion of carriers and thus the flow of the current. This is known as its rectification capability, and it is what allows the BAS40-L,315 to be used for circuitry that runs on DC power.

The diode is manufactured using a semiconductor substrate and can handle a maximum power dissipation of 0.6W. It has an operating junction temperature of -55°C to 125°C, and a storage temperature range of -55°C to 125°C. The device also has a low forward voltage drop, meaning that it requires very low energy to turn on, and can be triggered with just 0.35 V of DC. It also has a forward voltage reverse recovery time of 5 ns, which allows the device to quickly turn off and minimize power dissipation.

In terms of its mounting options, the BAS40-L,315 is available with an SOD-123FL package. It also features a “zero recovery” rectification, which allows for near-perfect smoothing of the converted DC waveform. This is important for LED lighting, for example, as it ensures that the LED remains lit and is not affected by any micro-shifts in voltage or current.

The diode’s maximum repetitive peak reverse voltage is rated at 30V, with a maximum forward current of 0.5A, a reverse recovery time of 0.5A, and a maximum forward surge current of 8.5A. Its built-in capacitance of 20pF is suitable for general switching applications.The BAS40-L,315 can be used in many applications, such as cellular phones, digital cameras, automotive electronics, white goods, factory automation, battery chargers, air conditioners, energy meters, home appliances, and motor control.

In conclusion, the BAS40-L,315 is a reliable single diode rectifier which is designed to provide a high surge current capability, low forward voltage drop and low switching losses. It is well-suited for a variety of applications, including LED lighting, SMPS circuits, and more. It also features a “zero recovery” rectification and is available in an SOD-123FL package.
