Product Description
Vishay SMC3K85CAHM3_A/H is a bi-directional transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage transients caused by inductive load switching, lightning, and electrostatic discharge. Featuring a peak pulse power dissipation rating of 3000 W and housed in a compact surface mount DO-214AB package (SMC), this device offers superior clamping performance and fast response times critical for comprehensive transient protection.
This TVS Diode operates effectively over a broad temperature range from -55°C to 175°C, making it suitable for demanding industrial, automotive, telecommunications, and consumer electronics applications. The device is qualified to automotive standard AEC-Q101, ensuring reliable operation in automotive environments.
It features a minimum breakdown voltage (Vbr) of 94.4 V, a maximum peak pulse current (Ippm) of 21.9 A, and a clamping voltage (Vc) of 137 V, providing excellent suppression against overvoltage conditions. The maximum reverse stand-off voltage is rated at 120 V with a very low leakage current of 1 μA, enabling power-efficient and safe circuit designs.
Manufactured to meet multiple internationally recognized standards including J-STD-002, RoHS, UL 94, ISO 16750-2, ISO 7637-2:2011, and JESD 22-B102, this semiconductor device guarantees environmentally compliant, high-quality performance.
Applications include protection of ICs, MOSFETs, sensor lines, and signal paths in industrial equipment, automotive electronics, telecommunications infrastructure, and computing devices to mitigate damage from voltage surges and spikes.
The SMC3K series emphasizes low incremental surge resistance and outstanding clamping capability, ensuring enhanced durability and protection of the end equipment. This product is not recommended for PCB bottom side wave mounting due to thermal considerations.
Designed for bi-directional voltage transient absorption. 3000 W peak pulse power dissipation capability. Compact DO-214AB surface mount package. Fast response time minimizes voltage overshoot. Wide temperature range from -55°C to +175°C for harsh conditions.
Low leakage current for efficient energy use. Meets automotive and industry standards including AEC-Q101 and RoHS. Explore a broad range of Vishay transient voltage suppressors and other discrete semiconductors at EnvMart for your electronics protection needs.
