BAS85-M-18

Single Diodes Overview

The BAS85-M-18 is a small signal Schottky diode manufactured by Vishay Semiconductors, housed in a MiniMELF (SOD-80) case. It features a continuous reverse voltage of 30 V and a forward continuous current rating of 200 mA. The device exhibits low turn-on voltage characteristics, with typical forward voltages ranging from 240 mV at 0.1 mA to 800 mV at 100 mA. Electrical specifications include a maximum leakage current of 2 μA at 25 V reverse bias and a diode capacitance of 10 pF at 1 V reverse bias and 1 MHz frequency.

Single Diodes Feature Summary

• Features a low turn-on voltage suitable for applications requiring minimal forward voltage drop
• Protected by a PN junction guard ring against excessive voltage such as electrostatic discharges
• Designed for general purpose applications where very low forward voltage is required

Single Diodes Applications

• General purpose rectification
• Applications requiring very low forward voltage
• Protection against electrostatic discharge

Single Diodes Procurement Notes

Verify the specific ordering suffix matches the required packaging option. The -18 suffix indicates tape and reel packaging on a 13-inch reel. Confirm that the MiniMELF (SOD-80) package dimensions align with the intended footprint design. Ensure thermal management accounts for the specified power dissipation limits under operating conditions.

Single Diodes Selection Notes

Select this component when a compact SMD Schottky diode with low forward voltage is needed. The MiniMELF package offers space-saving benefits compared to larger through-hole options. Consider the 30 V reverse voltage rating and 200 mA current capacity for circuit requirements. Verify compatibility with automated assembly processes due to the tape and reel availability.

Single Diodes Part Context

The BAS85-M belongs to Vishay's series of small signal Schottky diodes designed for efficiency and reliability. These devices utilize silicon technology to provide fast switching capabilities and low power loss. The product line emphasizes robustness against electrostatic discharge events, making them suitable for sensitive electronic circuits requiring dependable performance in compact form factors.

Single Diodes Replacement Considerations

Check datasheets for alternative Schottky diodes in the SOD-80 package with similar voltage and current ratings. Ensure replacement parts maintain comparable forward voltage characteristics and reverse leakage specifications. Verify that any substitute component meets the same thermal resistance and operating temperature range requirements.
