Product Description
Bourns SMAJ12CA is a 1-element bi-directional TVS diode specifically designed for transient voltage suppression with a peak pulse power dissipation of 400 W. This diode uses a surface mount DO-214 (SMB) package with two pins, making it compact and suitable for high efficiency PCB mounting applications.
Featuring a minimum breakdown voltage of 13.3 V and maximum reverse stand-off voltage of 12 V, it effectively clamps voltage spikes to protect sensitive electronic components. Its high peak pulse current rating of 35 A enables it to absorb substantial transient surges.
The device operates reliably in harsh environments with a temperature range of -55°C to 150°C, making it suitable for automotive and industrial applications. It complies with the automotive standard AEC-Q101 to ensure stringent quality and performance requirements.
Compact dimensions of 4.57 mm length, 2.92 mm width, and 2.42 mm height minimize PCB footprint without sacrificing protection capability. Its maximum reverse leakage current is exceptionally low at 5 μA, preventing unwanted current drain under normal operating conditions.
The diode configuration is single-element and is bi-directional for surge protection on both polarities. Mount type is surface for SMT assembly processes. Test current is 1 mA ensuring reliable characterization and testing.
Provides essential ESD protection for electronic and power systems.
This Bourns TVS diode is integral to safeguarding electronic equipment in industrial, telecommunications, automotive, aerospace, and manufacturing sectors. It serves as a crucial component in designs where transient voltage suppression enhances system reliability and longevity.
Choose Bourns SMAJ12CA for robust transient voltage suppression in your PCB designs requiring a compact, high-power, bi-directional TVS diode. Explore more high-quality electronic semiconductor components and TVS Diodes in the Electronics & Electricals category at EnvMart.
