# SMAJ33A-13-F (Component) ## Description 53.3V Clamp 7.5A Ipp Tvs Diode Surface Mount SMA TVS diode SMA 33V The SMAJ33A-13-F is a surface-mount transient voltage suppression (TVS) diode designed to protect sensitive electronic components from voltage spikes and transient events. It is typically used in circuits exposed to electrostatic discharge, inductive load switching, and other transient voltage conditions. The device operates by clamping excessive voltage to a safe level, thereby preventing damage to downstream components. Its compact surface-mount package enables efficient use of board space while maintaining reliable thermal and electrical performance. Device Overview This component is constructed using silicon avalanche technology, providing fast response time to transient events. It is intended for use in high-reliability applications where overvoltage protection is critical. The unidirectional configuration ensures effective suppression in circuits with a defined polarity. The device is optimized for low leakage current under normal operating conditions and high surge capability during transient events. Electrical Characteristics The diode is designed to operate with a defined stand-off voltage, ensuring it remains non-conductive during normal system operation. Upon exceeding the breakdown threshold, the device transitions into conduction, clamping the voltage to a specified level. It supports high peak pulse power dissipation and is capable of handling repeated transient events without significant degradation. Mechanical and Packaging Information The device is provided in a compact surface-mount package suitable for automated assembly processes. The package is designed for efficient heat dissipation and mechanical robustness, supporting standard reflow soldering techniques. Terminal finishes are compatible with common PCB manufacturing processes and ensure reliable solder joints. Applications Suitable for use in consumer electronics, industrial control systems, telecommunications equipment, and automotive electronics where protection against voltage transients is required. Common use cases include power supply lines, data lines, and interface ports. Environmental and Reliability Considerations The component is designed to meet standard environmental and reliability requirements for electronic components. It is suitable for operation across a wide temperature range and is built to withstand typical handling and assembly stresses. #commonpartslibrary #circuitprotection #tvsdiode ## Component Details - **Owner:** lcsc - **Created:** 11/4/2024 - **Last Updated:** 5/13/2026 - **Visibility:** Public - **Datasheet URL:** https://storage.googleapis.com/graviton-electric-symbols/document_assets/lcsc/2304140030_Diodes-Incorporated-SMAJ33A-13-F_C134981.pdf - **JLCPCB Part Class:** Extended Part - **Package or Case Code:** SMA_L4.4-W2.6-LS5.0-RD - **Manufacturer Part Number:** SMAJ33A-13-F - **Manufacturer Name:** DIODES(美台) - **Part Type:** TVS - **Product Info Url:** https://lcsc.com/product-detail/TVS_DIODES_SMAJ33A-13-F_SMAJ33A-13-F_C134981.html - **LCSC Part Number:** C134981 - **Used in:** 114 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
