Product Description
Bourns SMAJ48A 1-Element Uni-Directional TVS Diode is a high-performance transient voltage suppressor designed to protect electronic circuits from voltage spikes and electrostatic discharge (ESD). Featuring a peak pulse power dissipation of 400W, this diode is configured as a single element with uni-directional operation, making it suitable for protecting sensitive components in industrial, automotive, and consumer electronic applications.
The diode is housed in a compact DO-214 (SMB) surface mount package, measuring 4.57mm in length, 2.92mm in width, and 2.42mm in height. It supports reliable operation within an extended temperature range from -55°C to 150°C, making it suitable for harsh environments.
With a minimum breakdown voltage of 53.3V and a maximum reverse stand-off voltage of 48V, the SMAJ48A provides strong clamping at 3.5V to limit voltage surges. It supports a maximum peak pulse current of 35A to handle transient events effectively. The maximum reverse leakage current is low at 5μA, reducing power losses in normal operation.
Its automotive AEC-Q101 qualification adds assurance for use in automotive electronic systems. This diode is ideal for protection in industrial automation, instrumentation, telecommunications, power supplies, and other electronic equipment requiring transient voltage suppression.
