BAT721S,215

Overview

The BAT721S,215 is a planar Schottky barrier dual diode featuring an integrated guard ring for stress protection. It is encapsulated in a SOT-23 small Surface-Mounted Device plastic package with three terminals. The device supports a maximum continuous forward current of 200 mA per diode and a reverse voltage rating of 40 V. Key electrical parameters include a maximum forward voltage of 550 mV at 200 mA, a typical capacitance of 40 pF at 0 V reverse bias, and a non-repetitive peak forward current capability of 1 A. The junction temperature range extends from -65 °C to 125 °C.

Feature Summary

• Low forward voltage characteristics
• Low capacitance performance

Applications

• Ultra high-speed switching
• Line termination
• Voltage clamping
• Reverse polarity protection

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration before procurement. Confirm that the application environment does not require automotive qualification, as this specific part number is designated for general industrial use rather than automotive standards. Ensure thermal management strategies account for the specified thermal resistance values during operation.

Selection Notes

Select this component when low forward voltage drop and minimal capacitance are critical for circuit efficiency and signal integrity. The SOT-23 package offers a compact footprint suitable for space-constrained designs. Evaluate the 40 V reverse voltage rating against peak transient voltages to ensure adequate margin for the intended operating conditions.

Part Context

This component belongs to the Nexperia BAT721 series of Schottky barrier diodes. It shares the same physical package and core electrical architecture as other variants in the family but may differ in specific marking codes or manufacturing site identifiers. The 'S' designation indicates the dual diode configuration within the standard SOT-23 outline.
