STMicroelectronics SM6T30CAY is a 1-Element Bi-Directional Transil Transient Voltage Suppressor (TVS) diode designed for automotive and industrial electronics protection. It provides a peak pulse power dissipation of 600 W, making it highly effective in suppressing voltage surges and electrostatic discharges that could damage sensitive circuits.
Packaged in a DO-214AA (SMB) surface mount configuration with 2 pins, this diode offers ease of assembly and is ideal for automated manufacturing processes. It features a minimum breakdown voltage (Vbr) of 28.5 V and a maximum reverse stand-off voltage (Vwm) of 25.6 V, effectively clamping transient voltages to a maximum of 53.5 V (clamping voltage VC).
Designed to operate reliably across a wide temperature range from -55°C up to 150°C, the SM6T30CAY meets stringent automotive AEC-Q101 standards, ensuring excellent performance in demanding environments such as automotive power supply lines, industrial machinery, consumer electronics, and telecommunications equipment protection.
The device's high peak pulse current capability of 75 A and ultra-low leakage current of 1 μA contribute to enhanced surge protection without impacting steady-state operation. Its compact footprint (4.6 mm length, 3.95 mm width, 2.45 mm height) enables space-saving PCB layouts.
Bi-directional surge protection with high power dissipation. Wide operating temperature range for harsh conditions. Automotive grade with AEC-Q101 certification. Surface mount DO-214 package ideal for automated assembly.
Low leakage current and high peak pulse current capabilities.
This TVS Diode is suitable for protecting automotive circuits according to ISO 7637-2 and electrostatic discharges per ISO 10605 standards. It is widely used in automotive electronics, industrial equipment, power supplies, communication interfaces, and consumer electronic devices for robust transient voltage suppression.
