1N5711WS-7

Overview

The 1N5711WS-7 is a surface mount Schottky barrier diode manufactured by Diodes Incorporated in an SOD323 package. It features a peak repetitive reverse voltage of 70 V and a forward continuous current rating of 15 mA. The device dissipates up to 150 mW of power with a thermal resistance of 650 °C/W. Electrical characteristics include a maximum reverse leakage current of 200 nA at 50 V, a forward voltage drop ranging from 0.41 V to 1.00 V depending on current, and a total capacitance of 2.0 pF. Operating temperatures range from -55°C to +125°C.

Feature Summary

• Guard ring construction provides transient protection capabilities.
• Low forward voltage drop and fast switching speed optimize efficiency.
• Low capacitance design supports high-frequency signal applications.
• Surface mount package facilitates automated insertion processes.

Applications

• Protection of MOS devices against transients
• Steering, biasing, and coupling diodes for logic circuits
• Fast switching and low logic level applications

Procurement Notes

Verify the specific ordering suffix '-7-F' confirms tape and reel packaging containing 3000 units per carrier. Confirm compliance requirements such as RoHS 3 and halogen-free status match project specifications. Ensure the SOD323 footprint aligns with the suggested pad layout dimensions provided in the mechanical data section of the datasheet.

Selection Notes

Select this component when a small surface mount Schottky diode is required for low-voltage, low-current applications. The 15 mA current rating limits suitability for higher power loads. Consider the 2.0 pF capacitance for RF or high-speed digital environments where low parasitic effects are critical. Verify that the 70 V reverse voltage rating exceeds the circuit's peak operating voltage.

Part Context

This part belongs to the 1N5711 series of Schottky barrier diodes. While the standard 1N5711 utilizes an axial leaded DO-35 package, the 1N571WS variant adapts the same electrical performance into a compact SOD323 surface mount form factor. This allows designers to maintain similar switching characteristics while optimizing board space and enabling automated assembly.

Replacement Considerations

Direct replacements must match the SOD323 package and 15 mA/70 V ratings. Verify if automotive grade variants with Q-suffixes are required for specific change control needs. Standard 1N5711 axial parts are not direct physical substitutes without PCB redesign.
