Overview
The BAT54S-HE3-18 is a dual serial Schottky barrier diode from Vishay, housed in an SOT-23 surface-mount package. It features a repetitive peak reverse voltage of 30 V and a continuous forward current rating of 200 mA. The device exhibits low forward voltage drop and fast switching characteristics with a typical reverse recovery time of 5 ns. It operates within a junction temperature range of -55 °C to +125 °C and includes a PN junction guard ring for electrostatic discharge protection.
Feature Summary
- Dual serial configuration with integrated guard ring for stress protection
- Low forward voltage and negligible switching losses
- AEC-Q101 qualified automotive grade construction
Applications
- Ultra high-speed switching circuits
- Voltage clamping applications
- Reverse polarity protection
- Line termination networks
Procurement Notes
Verify the HE3 suffix indicates AEC-Q101 qualification and commercial-grade RoHS compliance. Confirm the -18 packaging code corresponds to 10K units per 13-inch reel. Validate that the specific batch matches the Rev 1.9 datasheet specifications before integration into production designs.
Selection Notes
Select this component when a compact dual-diode solution requires serial internal connection within an SOT-23 footprint. The HE3 variant provides necessary automotive reliability standards compared to standard E3 versions. Ensure circuit requirements align with the 30 V reverse voltage limit and 200 mA continuous current capacity.
Part Context
This part belongs to the Vishay BAT54 series of small signal Schottky diodes. The series encompasses single and dual configurations including common anode (BAT54A), common cathode (BAT54C), and serial (BAT54S) arrangements. All variants share similar low capacitance and fast switching properties optimized for surface-mount assembly.
Replacement Considerations
Cross-reference with Nexperia BAT54S or Diodes Inc BAT54S for equivalent pinout and electrical performance. Verify that alternative manufacturers meet the same AEC-Q101 qualification if automotive usage is required.
