BAT46WJ,115 Schottky Diode Specifications and Applications

ElecSuppliers Part Number GuideSep 26, 2026

BAT46WJ,115 is a single Schottky barrier diode from Nexperia. It is designed for general-purpose switching, rectification, power management, and signal-related applications where low forward voltage and fast switching characteristics are required.

The device is supplied in a compact SOD-323F surface-mount package and is rated for a repetitive peak reverse voltage of 100 V. Its average forward current rating is 250 mA.

BAT46WJ,115 Key Specifications

BAT46WJ,115 has a 100 V repetitive peak reverse voltage and a 250 mA average forward current rating. The maximum forward voltage is specified at 850 mV, while the forward surge current is rated at 2.5 A.

The diode has a typical reverse recovery time of 5.9 ns, making it suitable for circuits that require faster switching than conventional PN junction diodes. The device can operate at temperatures up to 150°C.

BAT46WJ,115 Package and Construction

BAT46WJ,115 uses the SOD-323F package, also identified as SC-90 in distributor specifications. It is a two-pin surface-mount device designed for compact PCB layouts and automated assembly.

The Schottky structure provides a relatively low forward voltage and fast switching behavior. The device also incorporates a guard ring for stress protection, supporting reliable operation in switching and rectification circuits.

BAT46WJ,115 Electrical Characteristics

The 100 V reverse voltage rating provides protection against reverse voltage conditions within the specified operating limits. When selecting the diode, engineers should also consider forward current, surge current, reverse leakage current, capacitance, and power dissipation.

The low reverse recovery time is useful in switching applications because it can reduce switching losses compared with slower diode technologies. However, actual circuit performance depends on operating voltage, current, switching frequency, PCB layout, and surrounding components.

BAT46WJ,115 Applications

BAT46WJ,115 can be used in power management circuits, signal switching, protection circuits, test and measurement equipment, and other electronic designs requiring a small Schottky diode.

Typical applications include low-current rectification, reverse polarity protection, voltage clamping, switching circuits, detector circuits, and power supply control.

Its compact SOD-323F package also makes it suitable for space-constrained PCB designs where a small surface-mount diode is required.

BAT46WJ,115 Design Considerations

When designing with BAT46WJ,115, engineers should verify the maximum reverse voltage and average forward current under the actual operating conditions. Surge current should also be considered where the circuit may experience short-duration current peaks.

Forward voltage affects conduction loss, particularly when the diode carries continuous current. Reverse leakage and junction capacitance can become more important in high-impedance or high-frequency circuits.

The PCB footprint should follow the manufacturer's recommended dimensions to ensure proper soldering and thermal performance.

BAT46WJ,115 Compared With Other Schottky Diodes

The BAT46 family includes several Schottky diode versions with different package configurations and electrical characteristics. BAT46WJ,115 is specifically supplied in the SOD-323F package and has a 100 V repetitive peak reverse voltage rating.

When selecting an alternative, engineers should compare reverse voltage, forward current, forward voltage, reverse leakage, switching characteristics, package dimensions, and thermal specifications. A diode with the same nominal voltage rating is not necessarily a direct replacement.

BAT46WJ,115 Sourcing Considerations

When sourcing BAT46WJ,115, buyers should use the complete manufacturer part number because similar BAT46 series devices may have different package styles or ordering codes.

Distributor information identifies BAT46WJ,115 as an active Nexperia product, although current inventory and lead times vary between suppliers.

For production procurement, buyers should confirm manufacturer, exact part number, package, packaging quantity, production status, traceability, and current delivery schedule before placing volume orders.
