Description

SMBJ28A is a bi-directional transient voltage suppression (TVS) diode designed to protect sensitive electronic components from voltage spikes. It is part of the SMBJ series, which is known for its reliability and effectiveness in clamping transient voltages. The SMBJ28A specifically has a breakdown voltage of 28V, making it suitable for applications requiring over-voltage protection in circuits operating at or below this voltage level.
The device features a low clamping voltage, fast response time, and high surge capability, making it ideal for protecting against ESD (electrostatic discharge) and other voltage transients. It is available in a surface-mount package, which facilitates easy integration into various electronic systems. Common applications include consumer electronics, telecommunications, automotive systems, and industrial equipment. By using SMBJ28A, designers can enhance circuit robustness and longevity.

Features

The SMBJ28A is a bidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic components from voltage spikes. Key features include:
1. Reverse Working Voltage: 28V, ensuring effective clamping of overvoltage transients.
2. Power Rating: 600W peak pulse power (for 8/20 µs wave), providing robust protection against transients.
3. Low Clamping Voltage: Limits the voltage during transient events, protecting downstream components.
4. Fast Response Time: Quick reaction to voltage spikes, minimizing potential damage.
5. Package Type: Available in a DO-214AA (SMB) package, suitable for surface mount applications.
6. Temperature Range: Operates typically within -55°C to +150°C, ensuring reliability in various environments.
7. Bidirectional Operation: Protects both polarities, making it versatile for AC and DC applications.
These features make the SMBJ28A ideal for applications in telecommunications, computer equipment, and consumer electronics where overvoltage protection is crucial.

Package

The SMBJ28A is typically packaged in a DO-214AA (SMB) package type. This surface-mount package is designed for general-purpose rectification and surge protection applications.

Pinout

The SMBJ28A is a transient voltage suppressor (TVS) diode and is part of the SMBJ series. It has a standard DO-214AA package with a pin count of 2. The device is designed to protect sensitive electronic components from voltage spikes by clamping excess voltage to a safe level.
