Product Description
STMicroelectronics SM15T12A is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and transient surges. Rated at 1.5 kW peak pulse power, this SMC package diode supports surface mounting for compact PCB integration.
The diode features a single unidirectional configuration offering reliable protection against transient voltages by clamping at 21.7 V. Its electrical characteristics include a minimum breakdown voltage of 11.4 V, a maximum reverse stand-off voltage of 10.2 V, and a maximum peak pulse current of 461 A. The device is tested at 1 mA test current and performs optimally within a wide temperature range of -55°C to 150°C.
The SM15T12A's physical dimensions (7.15 mm x 6.25 mm x 2.45 mm) enable integration in a variety of electronic assemblies requiring compact voltage suppression solutions. The maximum reverse leakage current is limited to 5 μA, improving energy efficiency and reducing quiescent current in circuits.
This diode is typically used in industrial, automotive (non-certified), telecommunications, and consumer electronic applications to mitigate transient voltage threats effectively. It conforms to standard semiconductor specifications but has no specific industry certifications.
The device provides high transient voltage protection with a 1.5 kW pulse power rating. Uni-directional configuration ensures effective suppression of positive voltage spikes. Surface mount technology compatible SMC package facilitates automated mounting processes.
Wide operating temperature range allows use in extreme environmental conditions. Low leakage current minimizes power loss in standby modes. Compact design supports high-density circuit board layouts. No automotive certification; suitable for general electronic protection.
Ideal for engineers and manufacturers requiring reliable transient voltage suppression, the SM15T12A exemplifies quality and performance in protection diodes.
