BAV99 RFG

Overview

The BAV99 RFG is a small signal switching diode manufactured by Taiwan Semiconductor. It features a dual series configuration housed in an SOT-23 surface-mount package. Key electrical specifications include a peak reverse voltage of 100 V, a maximum forward current of 215 mA, and a surge current rating of 2 A. The device exhibits a fast recovery time of 4 ns with a forward voltage of 1.25 V and a reverse current of 500 nA. It operates within a temperature range of -55 C to +150 C and holds AEC-Q101 qualification.

Feature Summary

• Dual series configuration for compact circuit integration
• Fast switching capability with 4 ns recovery time
• Automotive-grade reliability via AEC-Q101 qualification
• Wide operating temperature range from -55 C to +150 C

Applications

• High-speed switching circuits
• Automotive electronics systems
• Signal processing applications

Procurement Notes

Verify the specific suffix 'RFG' against the official Taiwan Semiconductor datasheet to confirm packaging details such as reel or cut tape specifications. Ensure the component meets AEC-Q101 automotive standards if required for your application. Cross-reference the manufacturer part number to avoid confusion with generic BAV99 variants from other suppliers that may have different electrical tolerances or pin configurations.

Selection Notes

Select this component when a dual series switching diode with 100 V reverse voltage capability is required in an SOT-23 package. The 4 ns recovery time makes it suitable for high-frequency applications. Consider the AEC-Q101 qualification for automotive environments. Compare the 215 mA forward current and 500 nA reverse leakage against circuit requirements to ensure adequate performance margins under varying thermal conditions.

Part Context

This component belongs to the BAV99 family of small signal switching diodes. While the standard BAV99 often specifies 70 V reverse voltage, this specific variant from Taiwan Semiconductor offers a higher 100 V rating. It shares the common SOT-23 footprint but differs in electrical ratings compared to other manufacturers' versions of the same base model number.

Replacement Considerations

BAV99HE3-TP (MCC) offers identical 100 V rating, 215 mA current, and 4 ns recovery time in SOT-23 with AEC-Q101 qualification.
