BAP64-04W-TP

RF Diode Overview

The BAP64-04W-TP is a general-purpose pin diode manufactured by Micro Commercial Components (MCC) in the SOT-323 surface-mount package. It operates within a junction temperature range of -55°C to +150°C and features a maximum continuous reverse voltage of 175 V and a forward current rating of 100 mA. The device dissipates up to 200 mW at 90°C ambient temperature with a thermal resistance of 625°C/W. Electrical characteristics include a typical reverse leakage current of 10 µA at 175 V, a forward voltage of 1.1 V at 50 mA, and low capacitance values ranging from 0.23 pF to 0.52 pF depending on bias conditions.

RF Diode Feature Summary

• Low diode capacitance for high-frequency signal integrity
• Low diode forward resistance to minimize signal loss
• Halogen-free 'Green' device compliant with environmental standards

RF Diode Applications

• High-frequency switching circuits
• RF signal routing and attenuation
• General-purpose rectification in compact designs

RF Diode Procurement Notes

Verify component authenticity by purchasing exclusively from authorized MCC distributors or directly from the manufacturer. Counterfeit parts lack full traceability and may fail quality standards. Confirm the ordering suffix '-TP' indicates tape-and-reel packaging containing 3000 pieces per reel. Ensure RoHS compliance requirements are met for your specific assembly process.

RF Diode Selection Notes

Select this component when low capacitance and fast switching are required in a small SOT-323 footprint. The 175 V reverse voltage rating suits moderate voltage applications. Consider the 200 mW power dissipation limit and 625°C/W thermal resistance for thermal management in dense PCB layouts. Verify that the 1.1 V forward voltage drop aligns with system efficiency targets.

RF Diode Part Context

The BAP64-04W belongs to the BAP64 series of general-purpose pin diodes, which also includes the BAP64-05W and BAP64-06W variants. These devices share the same SOT-323 package and core electrical characteristics but differ in specific marking codes. The series is designed for applications requiring low capacitance and low forward resistance in space-constrained environments.

RF Diode Replacement Considerations

Direct substitutes include the BAP64-05W and BAP64-06W from the same manufacturer family. Cross-manufacturer replacements must match the SOT-323 package, 175 V reverse voltage, and low capacitance specifications. Verify thermal resistance and forward voltage characteristics before implementation.
