BAT54C-E3-18

Overview

The BAT54C-E3-18 is a dual common cathode Schottky barrier diode manufactured by Vishay Semiconductors. It operates with a repetitive peak reverse voltage of 30 V and a continuous forward current of 200 mA. The device features a maximum forward voltage of 240 mV at 0.1 mA and a typical reverse recovery time of 5 ns. Packaged in an SOT-23 case, it includes a PN junction guard ring for electrostatic discharge protection.

Feature Summary

Dual common cathode configuration within a compact surface-mount package
PN junction guard ring provides protection against excessive voltage and electrostatic discharges
Low turn-on voltage combined with fast switching characteristics

Applications

DC/DC converter circuits
Power management systems
General purpose rectification applications

Procurement Notes

Verify the specific ordering suffix to confirm packaging requirements. The '-18' designation indicates tape and reel packaging on a 13-inch reel containing 10,000 units per box. Confirm that the base part number corresponds to the commercial grade RoHS-compliant variant rather than the automotive HE3 series.

Selection Notes

Select this component when a low forward voltage drop and rapid switching speed are required in a small form factor. The dual common cathode arrangement allows for efficient circuit design in power management tasks. Ensure the application remains within the specified thermal resistance limits and operating temperature range.

Part Context

This component belongs to the BAT54 series of small signal Schottky diodes from Vishay Semiconductors. The series encompasses single and dual configurations, including common anode and serial variants. The E3 suffix denotes compliance with RoHS standards for commercial grade applications.
