Features

The SMBJ24A is a 24V bidirectional TVS diode designed for transient voltage suppression in electronic circuits. Key features:
- Voltage Rating: 24V (standoff), 26.7V (breakdown), 38.9V (clamping).
- Bidirectional Protection: Safeguards against both positive and negative voltage spikes.
- High Surge Capacity: Handles 600W peak pulse power (8/20µs waveform).
- Low Clamping Voltage: Limits overvoltage effectively to protect sensitive components.
- Fast Response Time: Reacts in <1ns to transient events.
- Package: Compact SMB (DO-214AA) surface-mount form factor.
- Applications: Used in power supplies, communication ports, automotive systems, and other circuits requiring ESD/lightning protection.
Ideal for IEC 61000-4-2/4/5 compliance.

Application

The SMBJ24A is a TVS diode designed for transient voltage suppression in various applications. Key areas include:
1. Electronics Protection – Safeguards sensitive components in power supplies, communication devices, and data lines from voltage spikes.
2. Automotive Systems – Protects ECUs, sensors, and infotainment systems from load dump and ESD.
3. Industrial Equipment – Shields control systems, PLCs, and motor drives from surges.
4. Telecom & Networking – Secures routers, switches, and base stations from lightning-induced transients.
5. Consumer Electronics – Guards USB ports, HDMI interfaces, and charging circuits against ESD.
Its 24V clamping voltage makes it ideal for 12V–24V DC systems.

Package

The SMBJ24A is a TVS diode in an SMB (Surface Mount) package. It's designed for surface mounting on PCBs, offering robust ESD and surge protection. The SMB package is compact, with a standard DO-214AA footprint, suitable for automated assembly. Key features include a 24V breakdown voltage and high surge capability. Ideal for protecting sensitive electronics from transient voltage spikes.
