BAT54-E3-18

Single Diodes Overview

The BAT54-E3-18 is a single small signal Schottky diode manufactured by Vishay Semiconductors. It features a repetitive peak reverse voltage of 30 V and a forward continuous current rating of 200 mA. The device operates within a junction temperature range of -55 °C to +125 °C and dissipates up to 230 mW. Electrical characteristics include a maximum leakage current of 2 μA at 25 V reverse bias and a typical diode capacitance of 10 pF at 1 V reverse voltage and 1 MHz frequency. The component utilizes an SOT-23 surface-mount package.

Single Diodes Feature Summary

• Features very low turn-on voltage and fast switching capabilities
• Protected by a PN junction guard ring against excessive voltage such as electrostatic discharges

Single Diodes Applications

• General purpose switching applications
• Low voltage rectification circuits
• High speed switching logic interfaces

Single Diodes Procurement Notes

Verify the specific ordering code suffix matches the required packaging format, as the datasheet indicates availability in both tape and reel configurations for this part number. Confirm RoHS compliance status aligns with project requirements, noting that the base E3 designation signifies commercial grade compliance. Ensure the manufacturer identification corresponds to Vishay Semiconductors or its authorized divisions.

Single Diodes Selection Notes

Select this component for designs requiring a single Schottky diode in a compact SOT-23 footprint. The 30 V reverse voltage rating suits low voltage signal processing tasks. Consider the thermal resistance of 430 K/W when determining heat dissipation needs on fiberglass substrates. Verify that the 200 mA continuous forward current meets the circuit load requirements without exceeding the 125 °C junction temperature limit.

Single Diodes Part Context

This component belongs to the BAT54 family of small signal Schottky diodes produced by Vishay Semiconductors. The series includes variants such as BAT54A, BAT54C, and BAT54S, which offer different internal dual-diode constructions like common anode or serial configurations. The BAT54-E3-18 specifically denotes the single diode version packaged in tape and reel format.

Single Diodes Replacement Considerations

Direct substitutes within the same Vishay family include BAT54A-E3-18 (common anode), BAT54C-E3-18 (common cathode), and BAT54S-E3-18 (serial). For AEC-Q101 qualified versions, consider the HE3 series equivalents such as BAT54-HE3-18.
