STMicroelectronics (NYSE:STM)
GENEVA, SWITZERLAND, November 11, 2026 /EINPresswire.com/ — STMicroelectronics’ TVS221SC-1T2 is more than 60% smaller than conventional transient voltage suppressors (TVS), while maintaining a constant 26.2V clamping voltage over the entire 16A surge-current range and up to 125°C.
Leveraging an internal voltage-control loop, the single-line, unidirectional TVS221SC-1T2 outperforms the clamping protection of conventional suppressors in significantly larger QFN-2L, SOD128, and SMA, SMB, and SMC packages. With a close ratio between clamping voltage and breakdown voltage, ST’s new diodes let designers replace over-specified protection components with tightly optimized designs that are space-efficient, robust, and reliable.
Suitable for space-constrained equipment like consumer products, industrial electronics, home-automation, and healthcare devices, the TVS221SC-1T2 protects I/O pins and power connections such as VBUS in USB Type-C ports. With peak pulse current of 16A according to IEC 61000-4-5, ESD immunity exceeds IEC 61000-4-2 level 4 at ±8kV (contact discharge) and ±30kV (air discharge). Extremely low leakage current of 25nA (typical) helps prolong battery energy in portable equipment and IoT devices, and capacitance of 75nF preserves the integrity of low-speed data lines.
Housed in an ultra-small 0402 leadless SOD882 (1006 metric) low-profile package measuring 0.6mm x 1.0mm, the TVS221SC-1T2 is in production now and available from $0.10 for orders of 1000 pieces.
