BAV99W

Overview

The BAV99W is a small-signal switching diode manufactured by Taiwan Semiconductor Corporation, housed in an SOT-323 (SC-70) surface-mount package. It features a peak reverse voltage of 85 V and a maximum forward current of 150 mA. The device is designed for high-efficiency applications with low power loss characteristics.

Feature Summary

• High-speed switching capability
• Low leakage current operation
• Low power loss design

Applications

• General-purpose switching circuits
• High-speed switching applications

Procurement Notes

Verify the specific manufacturer designation, as BAV99W is widely produced by multiple vendors including Nexperia and onsemi. Confirm that the Taiwan Semiconductor variant matches the required 85V rating and 150mA current specifications. Ensure the SOT-323 package dimensions align with the PCB footprint requirements before finalizing procurement orders.

Selection Notes

Select this component when a compact SMD switching diode with low forward voltage drop is required. The SOT-323 package offers space savings compared to larger through-hole alternatives. Consider the 85V reverse voltage limit for circuit protection designs to ensure adequate safety margins against transient spikes.

Part Context

This component belongs to the general-purpose switching diode category within the Taiwan Semiconductor portfolio. It serves as a compact solution for signal processing and protection tasks where physical size constraints are critical. The device complements other SC-70 series components for integrated circuit protection strategies.

Replacement Considerations

Cross-reference with BAV99W variants from Nexperia or onsemi. Verify if the alternative part meets the 85V reverse voltage requirement, as some generic BAV99W parts may support up to 100V. Ensure pinout compatibility in the SOT-323 package.
