Product Description
DiodesZetex SMAJ75A-13-F is a robust 1-element uni-directional transient voltage suppressor (TVS) diode designed for protecting sensitive electronic equipment from voltage spikes. The diode is housed in a compact DO-214 surface mount package featuring two pins for straightforward PCB mounting.
This device supports a peak pulse power dissipation of 400 W, making it suitable for absorbing high energy transient surges typically encountered in power supply circuits and communication lines. It has a maximum reverse stand-off voltage of 75 V and a minimum breakdown voltage of 83.3 V ensuring precise voltage clamping and protection.
The clamping voltage of 121 V limits voltage transients effectively while the device operates reliably over a temperature range of -55°C to 150°C, suitable for industrial, automotive, and commercial electronics applications. With a peak pulse current of 3.3 A and a low maximum reverse leakage current of 5 μA, it provides efficient suppression without affecting normal circuit operation.
Its single element configuration provides uni-directional protection, ideal for circuits requiring protection against positive voltage transients. The device does not include built-in ESD protection but delivers high transient immunity in transient voltage suppression roles.
The compact dimensions of 4.6 mm length, 2.92 mm width, and 2.1 mm height make it space-efficient for PCB layouts. It complies with standard SMAJ series design ensuring compatibility with existing designs.
The diode configuration is single element designed for transient voltage suppression. It offers uni-directional voltage protection for DC circuits. Peak pulse power rating of 400 W allows absorption of high energy transient spikes.
Operating temperature range between -55°C and 150°C suits industrial environments. Compact DO-214 package ensures minimal PCB space usage. Low reverse leakage current minimizes power losses during normal operation.
This TVS diode is heavily used in industrial electronics, automotive electronics circuits, power supplies, communication equipment, and consumer devices that require robust transient voltage protection. Its reliable suppression of power surges helps to increase product lifetime and reduce malfunction risks.
