The new Bi-directional Silicon Controlled Rectifier structure has already moved into mass production within the company’s 0.13-micron BCD process. Unlike conventional electrostatic discharge safeguards that only address manufacturing-related shocks, this system-level solution manages continuous electrical stress during active vehicle operation, including compliance with the rigorous ISO 10605 standard.

SK keyfoundry Launches On-Chip EMC Shield for Automotive Chips
As vehicle electronics grow increasingly complex, SK keyfoundry has debuted a Bi-SCR-based protection technology designed to mitigate electromagnetic interference. By integrating this defense directly onto the chip, the South Korean manufacturer aims to eliminate the need for bulky external components while meeting stringent automotive reliability standards.

This design offers engineers flexible trigger-voltage adjustments and high-current handling within a compact footprint. By replacing external transient voltage suppressor diodes with an internal on-chip control mechanism, the foundry allows automotive designers to reclaim valuable board space and simplify circuit architecture. CEO Derek D. Lee noted that the technology marks a shift in market priorities, where robust electromagnetic compatibility has become as critical as component-level durability. Moving forward, the company intends to integrate these protection capabilities across its high-voltage LDMOS and BJT platforms to support power management chips and motor drivers.
