Product Description
The STMicroelectronics SM6T56CA is a high-performance, bi-directional Zener diode designed to provide robust protection against transient voltage surges and electrostatic discharges. Packaged in a compact DO-214AA (SMB) surface mount package, it is optimized for use in sensitive electronic devices and power management applications, especially in high-end equipment and switched-mode power supplies (SMPS).
This diode is capable of handling peak pulse power values up to 600 W with a 10/1000 μs waveform, and even higher surges up to 4 kW for short 8/20 μs events, providing strong protection against voltage spikes. The planar technology utilized in its construction ensures low leakage current - 0.2 μA at 25 °C and 1 μA at 85 °C - maintaining device reliability and minimizing power loss.
The diode operates efficiently between -55 °C and 150 °C, making it suitable for demanding industrial and automotive environments. The bi-directional feature allows protection on both voltage polarities, enhancing versatility in circuit designs.
The surface mount DO-214AA package measures 3.95 mm in length and 2.45 mm in height, featuring 2 pins for easy PCB mounting and stable mechanical performance. Its nominal Zener voltage is 47.6 V, making it ideal for voltage regulation and surge protection at this specific threshold.
High peak pulse power dissipation of 600 W for transient surge protection. Bi-directional Zener diode for comprehensive polarity protection. Low leakage current for enhanced circuit efficiency and reliability. Wide operating temperature range suitable for harsh environments.
