Product Description

Vishay SMA6F45A-M3/H is a 1-Element Uni-Directional Transient Voltage Suppressor (TVS) diode designed to provide robust protection against voltage transients. This diode offers a peak pulse power dissipation rating of 600 W and is housed in a low-profile DO-221 surface mount package measuring 4.35 mm in length, 2.7 mm in width, and 1 mm in height. It is engineered for precise clamping with a minimum breakdown voltage of 50 V and a maximum reverse stand-off voltage of 45 V.

The device is suitable for protecting sensitive electronics such as integrated circuits (ICs), MOSFETs, and signal lines from voltage spikes caused by inductive load switching and lightning surges. The diode supports operation over a wide temperature range from -55°C to 175°C and features a maximum peak pulse current of 42.6 A, making it reliable under high surge conditions.

Additional technical advantages include low maximum reverse leakage current of 1 µA, enhanced electrostatic discharge (ESD) protection, and compliance with MSL level 1 per J-STD-020 with maximum lead-free solder temperature of 260°C. The device’s low profile (typical height 0.95 mm) supports automated placement in manufacturing processes.

This TVS diode is ideal for industrial, telecommunications, consumer electronics, and computer applications where transient voltage protection is critical. It ensures component longevity and system reliability against transient overvoltage events.

Uni-directional diode configuration ensures effective transient voltage suppression. Compact DO-221 surface mount package optimizes PCB layout. 600 W peak pulse power dissipation handles high transient energy. Wide operating temperature range from -55°C to 175°C.

Low leakage current minimizes standby power consumption. ESD protection enhances component safety and durability. Compliant with industry standards for soldering and reliability. Designed for protecting ICs, MOSFETs, and sensitive signal lines.

Suitable for industrial, consumer, and telecommunication applications. Explore more products in the Electronics & Electricals > Semiconductor > TVS Diodes category on EnvMart for comprehensive transient voltage suppression solutions.
