Product Description
Vishay SMC3K22CAHM3_A/H Bi-Directional TVS Diode is a high-performance transient voltage suppressor designed for protecting sensitive electronic components from voltage transients induced by inductive switching and lightning impulses.
This diode features a surface mount DO-214AB (SMC) package and provides a peak pulse power dissipation of 3 kW with a 10/1000 μs waveform. Its bi-directional polarity makes it suitable for AC and DC voltage protection circuits.
The device operates reliably within a temperature range of -55°C to 150°C and complies with RoHS standards as well as AEC-Q101 automotive qualification, making it fit for use in automotive, industrial, and telecom equipment.
Key technical parameters include a minimum breakdown voltage (Vbr) of 24.4 V, a maximum reverse stand-off voltage (Vwm) of 22 V, and a clamping voltage (Vc) of 35.5 V. The maximum peak pulse current is rated at 84.5 A, with low incremental surge resistance that ensures efficient suppression of voltage spikes.
With a maximum reverse leakage current of just 1 μA and extremely fast response time, the TVS diode effectively safeguards sensitive ICs, MOSFETs, and signal lines of sensor units across consumer electronics, computer systems, industrial controls, automotive electronics, and telecommunications infrastructure.
Designed for robust transient voltage protection in multiple industrial and commercial applications. Compact surface mount form factor suitable for modern PCB assemblies. Compliance with automotive standards enhances reliability for vehicle electronics.
Low leakage current minimizes power losses during normal operation. Ideal for lightning and surge protection in sensitive electronic circuits. This product enables engineers and designers to build more reliable and resilient electronic systems by safeguarding critical components against damaging transients.
