BAV70W/SN/8X

Overview

The BAV70W/SN/8X is a small signal switching diode manufactured by Nexperia, housed in an SOT-323 (SC-70) surface-mount package. It features a dual configuration with a peak reverse voltage of 100 V and a maximum forward current of 150 mA. The device exhibits a fast recovery time of 4 ns and a low maximum diode capacitance of 1.5 pF. Electrical characteristics include a forward voltage of 1.25 V and a reverse leakage current of 500 nA. Power dissipation is rated at 200 mW, with an operating temperature range spanning from -65 °C to +150 °C.

Feature Summary

• High-speed switching capability with minimal reverse recovery time for efficient signal processing
• Low junction capacitance design suitable for high-frequency applications
• Compact SMD plastic package optimized for space-constrained PCB layouts

Applications

• High-speed switching circuits
• General-purpose signal switching
• Clamping and protection applications

Procurement Notes

Verify component status carefully as the product is listed as obsolete or end-of-life. Confirm availability through authorized distributors or secondary markets. Ensure the specific suffix matches the required reel quantity and tape-and-reel specifications. Validate authenticity via official Nexperia channels before integration into production designs.

Selection Notes

Select this component when a dual diode configuration in a compact SC-70 package is required. Consider the 100 V reverse voltage rating and 4 ns recovery speed for appropriate circuit demands. Evaluate thermal constraints given the 200 mW power dissipation limit in small packages. Verify compatibility with existing footprint designs utilizing SOT-323 footprints.

Part Context

This part belongs to Nexperia's BAV series of high-speed switching double diodes. It shares the same internal die and electrical characteristics as the standard BAV70W but is supplied in a specific tape-and-reel packaging format indicated by the SN/8X suffix. It serves as a compact alternative to larger through-hole or multi-die packages.

Replacement Considerations

Direct functional equivalents include the BAV70W and BAV70W-Q. Verify pinout compatibility and package dimensions when substituting. Check if automotive qualification (Q100) is required, as standard versions lack this certification.
