BAT81S-TR

Single Diodes Overview

The BAT81S-TR is a small signal Schottky barrier diode manufactured by Vishay Semiconductors. It features a DO-35 (DO-204AH) axial leaded package with an integrated protection ring against static discharge. The device is characterized by low capacitance, low leakage current, and very low switching time. Key electrical ratings include a maximum reverse voltage of 40 V, a forward continuous current of 30 mA, and a peak forward surge current of 500 mA. Typical forward voltage drop ranges from 330 mV at 0.1 mA to 1000 mV at 15 mA, with a typical diode capacitance of 1.6 pF.

Single Diodes Procurement Notes

Verify the specific part number suffix against official documentation to confirm packaging options such as tape and reel or ammopack configurations. Ensure that the selected component meets the required thermal resistance and junction temperature specifications for the intended operating environment. Cross-reference datasheet revision numbers to validate parameter accuracy before finalizing procurement orders.

Single Diodes Selection Notes

Select this component for circuits requiring low forward voltage drop and minimal reverse leakage current. The DO-35 package is suitable for through-hole mounting in general-purpose and switching applications. Consider the 40 V reverse voltage rating when designing power supplies or DC/DC converters where input voltages remain within safe operational limits.

Single Diodes Part Context

This component belongs to the BAT81S/BAT82S/BAT83S series of small signal Schottky diodes. While sharing similar structural features and performance characteristics, differentiation among these variants is primarily based on their maximum reverse voltage ratings. The BAT81S variant specifically offers a 40 V rating, distinguishing it from higher voltage counterparts within the same product family.
