Product Description
The STMicroelectronics SM30T33CAY is a 1-element bi-directional transient-voltage suppression (TVS) diode designed to protect sensitive electronic components from voltage spikes and transient surges. Rated for a peak pulse power dissipation of 3 kW, it is ideal for protecting circuitry in industrial, automotive, telecommunications, and consumer electronics applications.
This TVS diode features a single diode configuration with bi-directional polarity, making it suitable for circuits where polarity of transient voltages is unknown or can vary. It has a minimum breakdown voltage Vbr of 31.1 V and a maximum reverse stand-off voltage Vwm of 28 V, ensuring reliable suppression of transient voltages while not interfering with normal operation.
The device is housed in a surface mount DO-214 package type that facilitates automated assembly and compact PCB layouts. Its small package measures 7.15 mm in length, 6.25 mm in width, and 2.45 mm in height, making it suitable for space-constrained designs. It operates over a wide temperature range from -55°C to 150°C, passing the automotive AEC-Q101 standard, thus enabling use in automotive-grade electronics.
The SM30T33CAY can handle peak pulse currents up to 560 A with a test current of 1 mA and has a low clamping voltage of 50 V to effectively absorb high transient energy and protect downstream circuits. Its maximum reverse leakage current of only 200 nA ensures minimal power loss in steady state, enhancing energy efficiency.
This TVS diode is well-suited for environments requiring robust voltage transient protection, including industrial control systems, automotive electronics, power supplies, and telecommunications equipment. Designed to suppress voltage and current spikes efficiently, it prolongs the life and reliability of sensitive semiconductor devices against electrostatic discharge and electrical fast transients.
