Product Description
Vishay SMC3K12CAHM3_A/H is a high-performance bi-directional TVS (Transient Voltage Suppressor) diode designed to protect sensitive electronic circuits from voltage transients caused by inductive load switching, lightning strikes, and electrostatic discharge. This diode is housed in a compact DO-214AB (SMC) surface mount package, enabling integration in compact PCB layouts across multiple industries.
With a peak pulse power dissipation of 3 kW (10/1000 µs waveform), this component provides robust transient voltage suppression, ensuring downstream semiconductor devices like ICs, MOSFETs, and sensor lines are safeguarded effectively.
The device operates within a broad temperature range of -55°C to 150°C, making it suitable for industrial, automotive, telecommunications, and consumer electronics applications. Its excellent clamping voltage of 19.9 V and low incremental surge resistance assure fast response and reliable operation under surge conditions.
Compliance with RoHS regulations and qualification to the automotive AEC-Q101 standard underpin its suitability for automotive and other high-reliability environments. This device is not recommended for PCB bottom side wave mounting to prevent thermal damage.
Bi-directional transient voltage suppression for sensitive electronics. 3000 W peak pulse power dissipation capability. Excellent clamping voltage performance for fast surge response. Wide operating temperature range ideal for diverse industrial applications.
