Overview
The BAT54S-G3-18 is a small signal Schottky diode manufactured by Vishay General Semiconductor - Diodes Division. It features a dual serial circuit configuration housed in an SOT-23 surface-mount package. Key electrical parameters include a repetitive peak reverse voltage of 30 V, a continuous forward current of 200 mA, and a maximum forward voltage of 800 mV at 100 mA. The device exhibits a reverse recovery time of 5 ns and a diode capacitance of 10 pF. Operating temperature ranges from -55 °C to +125 °C.
Feature Summary
- Dual serial circuit configuration for compact design
- Very low turn-on voltage and fast switching characteristics
- Protected by a PN junction guardring against excessive voltage such as electrostatic discharges
- Molding compound meets UL 94 V-0 flammability rating
Applications
- Ultra high-speed switching
- Voltage clamping
- Reverse polarity protection
Procurement Notes
Verify the specific ordering code matches the required packaging quantity. The suffix G3 indicates green commercial grade material categorization compliant with RoHS standards. Confirm the reel size corresponds to the production volume requirements. Ensure the component version aligns with the latest datasheet revision to avoid discrepancies in mechanical or electrical specifications during integration.
Selection Notes
Select this component when a dual serial Schottky configuration is required in a minimal footprint. The SOT-23 package suits space-constrained designs. Consider the 30 V reverse voltage limit and 200 mA current capacity for suitability. The low capacitance and fast recovery make it appropriate for high-frequency applications where standard rectifiers would introduce excessive losses or delay.
Part Context
This part belongs to the BAT54 series of small signal Schottky diodes produced by Vishay Semiconductors. The series includes single and dual variants like BAT54, BAT54A, and BAT54C. The BAT54S specifically denotes the dual serial topology. These devices are designed for general-purpose signal processing and protection roles in consumer and industrial electronics utilizing surface-mount technology.
