- 30.6 W non-repetitive peak reverse power dissipation capability for robust protection against ESD and lightning-induced surges
- High-reliability silicon construction (AEC-Q101 compatible) suitable for automotive and industrial environments
Applications
The VS5V0BL1QST18R is used to protect sensitive 5 V signal lines in automotive ECUs, industrial I/O interfaces, and consumer electronics from ESD and transient voltage spikes. Its bidirectional configuration makes it suitable for data lines, communication buses, and power rails where both polarities of transient events must be suppressed. The high peak power rating of 30.6 W ensures reliable protection even against severe transient pulses in harsh operating environments.
