Product Description
STMicroelectronics SM15T33A is a 1-element uni-directional transient voltage suppressor (TVS) diode delivering 1.5 kW peak pulse power dissipation with robust transient protection in sensitive electronic circuits.
This surface mount device in an SMC package has a diode configuration of single uni-directional element, ensuring effective clamping of voltage spikes. The diode offers a minimum breakdown voltage (Vbr) of 31.4 V and a maximum reverse stand-off voltage (Vwm) of 28.2 V.
The peak pulse current rating is 169 A with a clamping voltage of 59 V, which makes it suitable for high-energy transient suppression applications in power and signal line protection.
It operates reliably within a wide temperature range from -55°C to +150°C, suitable for harsh industrial environments. The maximum reverse leakage current is only 1 µA, minimizing power loss and maintaining circuit efficiency.
The compact SMC package measures 7.15 mm (length) by 6.25 mm (width) and 2.45 mm (height) with two pins for easy surface mount PCB assembly. The single-element uni-directional configuration provides precise transient voltage protection.
High peak pulse power rating of 1.5 kW protects sensitive components effectively. Wide operating temperature and low leakage current enhance reliability in industrial applications. Compact SMC surface mount package integrates easily into automated assembly lines.
Widely applicable for transient voltage suppression in electronic power and signal interfaces.
This device is an ideal choice for transient voltage suppression in industrial, electronics manufacturing, power supply, and automotive systems that do not specifically require automotive certification.
