BAV170T-7

Overview

The BAV170T-7-F is a surface mount low leakage switching diode manufactured by Diodes Incorporated. It features a common cathode configuration with two silicon junctions housed in an SOT-523 package. The device supports a peak repetitive reverse voltage of 85V and a continuous forward current of 125mA per diode. Electrical characteristics include a maximum reverse leakage current of 5nA at 75V, a total capacitance of 2pF, and a reverse recovery time of 3μs. Operating temperature ranges from -65°C to +150°C.

Feature Summary

• Ultra-small surface mount package designed for automated insertion
• Very low leakage current suitable for high precision applications
• Qualified to AEC-Q101 standards for automotive reliability

Applications

• High precision instrumentation circuits
• Automotive electronic systems requiring high reliability
• Low leakage signal switching applications

Procurement Notes

Verify the specific ordering suffix matches the required packaging format. Confirm compliance with RoHS directives and lead-free plating requirements. Ensure the component meets AEC-Q101 qualification standards if used in automotive contexts. Check date codes for green molding compound specifications if halogen-free status is critical.

Selection Notes

Select this component when ultra-low leakage and small form factor are primary design constraints. The SOT-523 package offers space efficiency compared to larger outlines. Consider the thermal resistance and power dissipation limits relative to ambient operating conditions. Verify that the 85V reverse voltage rating exceeds the maximum circuit blocking requirements.

Part Context

This part belongs to the BAS116T, BAW156T, BAV170T, and BAV199T family of surface mount low leakage diodes. All members share the same SOT-523 mechanical outline and general feature set. Differentiation within the series is primarily based on specific leakage current thresholds and internal circuit configurations.

Replacement Considerations

Direct substitutes within the same family include BAS116T-7-F, BAW156T-7-F, and BAV199T-7-F. These parts share identical packaging and mounting dimensions. Verify electrical parameters such as leakage current and forward voltage against specific application requirements before substitution.
