The SMBJ33CA-13 from Diodes Incorporated is a robust transient voltage suppression (TVS) diode, designed to protect sensitive electronic equipment from voltage spikes and transients induced by lightning and other sudden voltage events. This TVS diode is a bi-directional, surface-mounted device that fits the SMB (DO-214AA) package, making it suitable for a wide range of applications, including consumer electronics, automotive systems, and industrial equipment.

Key Features

• Stand-Off Voltage: The SMBJ33CA-13 has a stand-off voltage of 33V, which allows it to tolerate transient over-voltage conditions without conducting significant current.
• Peak Pulse Power: It offers excellent surge capabilities with a peak pulse power of 600W for a 10/1000μs waveform, which ensures protection against high energy transients.
• Clamping Voltage: The clamping voltage is specified at a maximum of 53.3V, providing a rapid response to fast-rising transients.
• Bi-Directional Protection: As a bi-directional TVS diode, the SMBJ33CA-13 provides symmetrical protection for both positive and negative voltage transients.
• Low Incremental Surge Resistance: The device features low incremental surge resistance, minimizing the voltage drop across the diode when a surge occurs.
• Operating Temperature Range: It operates over a wide temperature range from -55°C to +150°C, ensuring reliability in harsh environments.
