Product Description
STMicroelectronics SMBJ28A-TR is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from voltage spikes and surges. Rated at 600 W peak pulse power dissipation, this diode is housed in a DO-214 surface mount package, enabling compact and efficient PCB assembly.
With a minimum breakdown voltage of 31.1 V and a maximum reverse stand-off voltage of 28 V, it effectively clamps transient voltages to a safe level of 59 V, protecting downstream components from damage. The diode is designed for uni-directional operation with 2 pins, making it suitable for a wide range of industrial and consumer electronics applications requiring transient surge protection.
The SMBJ28A-TR operates reliably across a broad temperature range from -55°C up to 150°C, ensuring stable protection under harsh environmental conditions. The low maximum reverse leakage current of 200 nA contributes to energy efficiency and minimal standby losses.
Typical applications include protection of power supplies, telecommunications equipment, automotive electronics, and other critical systems sensitive to transient overvoltages. The robust construction and tight clamping voltage specifications make this TVS diode ideal for surge suppression and electrostatic discharge (ESD) protection.
