Product Description
Vishay SMC3K14CAHM3_A/H Bi-Directional TVS Diode is a high-performance transient voltage suppressor designed for protection against voltage transients caused by inductive load switching and lightning strikes.
The device features a peak pulse power dissipation of 3 kW with a 10/1000 µs waveform, providing robust clamping capability and very fast response time to protect ICs, MOSFETs, sensor units, and signal lines in consumer electronics, industrial, automotive, telecommunications, and computer applications.
It is housed in a compact DO-214AB (SMC) surface mount package with dimensions 7.11 mm (L) × 6.22 mm (H) × 2.62 mm (W), enabling efficient PCB space usage.
This TVS Diode meets stringent quality standards including RoHS compliance and the automotive AEC-Q101 qualification, ensuring high reliability in demanding automotive environments.
The device operates over a wide ambient temperature range from -55°C to 150°C, with a peak pulse current rating of 129 A and low leakage current of 1 µA, making it suitable for sensitive and high-performance electronics protection.
The Vishay SMC3K14CAHM3_A/H is not recommended for PCB bottom side wave mounting to ensure optimal mounting and performance.
Industrial use cases include protection in automotive systems, telecommunications infrastructure, computing devices, industrial controls, and general electronic assemblies requiring transient voltage suppression.
Bi-directional polarity only for symmetrical transient protection. Excellent clamping and low incremental surge resistance provide superior transient voltage suppression. AEC-Q101 automotive qualification endorses its reliability for vehicular electronics.
Meets MSL level 1 per J-STD-020, allowing high temperature soldering processes. RoHS compliant and environmentally friendly design. Surface mount DO-214AB package enables flexible and compact PCB integration. For more electronic components and semiconductor devices, explore our extensive catalog at EnvMart.
