BAS40T-7

Single Diodes Overview

The BAS40T-7-F is a surface mount Schottky barrier diode manufactured by Diodes Incorporated. It features a single diode configuration housed in an SOT523 package. The device supports a peak repetitive reverse voltage of 40 V and a continuous forward current of 200 mA. Electrical characteristics include a maximum forward voltage of 1000 mV at 40 mA and a leakage current of 200 nA at 30 V reverse bias. Power dissipation is rated at 150 mW with a thermal resistance of 833 °C/W. Operating temperature ranges from -55°C to +125°C.

Single Diodes Feature Summary

• Low forward voltage drop for efficient power handling
• Fast switching capability with low reverse recovery time
• PN junction guard ring provides transient and ESD protection

Single Diodes Applications

• General purpose rectification in consumer electronics
• Clamping applications in signal processing circuits
• Protection against electrostatic discharge (ESD) events

Single Diodes Procurement Notes

Verify the specific ordering suffix, such as -7-F, to confirm tape and reel packaging quantities and compliance status. Confirm RoHS 3 and halogen-free designations match project requirements. Ensure the SOT523 footprint aligns with the PCB layout guidelines provided in the datasheet. Validate that the 150 mW power dissipation rating suits the thermal environment of the final assembly.

Single Diodes Selection Notes

Select this component when a compact Schottky diode with low capacitance is required for high-speed switching. The SOT523 package offers space savings compared to larger surface mount options. Consider the 40 V reverse voltage rating for low-voltage DC blocking applications. Evaluate the 200 mA forward current limit against peak load requirements to ensure reliable operation within specified thermal limits.

Single Diodes Part Context

This part belongs to the BAS40T series of surface mount Schottky barrier diodes. It shares electrical specifications with variants like BAS40-04T, BAS40-05T, and BAS40-06T, which differ primarily in internal pin configurations or dual-diode arrangements. The BAS40T specifically denotes the single-diode version within this family, designed for ultra-small surface mount applications requiring fast switching performance.
