SMAJ33A-E3/61

The SMAJ33A-E3/61 is a specific type of transient voltage suppressor (TVS) diode manufactured by Vishay, designed to protect sensitive electronic components from voltage spikes and transients. Here’s a detailed description of its features and specifications:

General Description:

• Type: Transient Voltage Suppressor (TVS) Diode
• Package: SMA (Surface Mount) package, which is compact and suitable for surface mount technology (SMT) applications.
• Configuration: Unidirectional, meaning it is designed to conduct current in one direction, providing protection against positive voltage transients.

Electrical Characteristics:

• Reverse Stand-Off Voltage (V_RWM): The SMAJ33A-E3/61 has a reverse stand-off voltage of 33V, which is the maximum voltage that can be applied without causing the diode to conduct.
• Clamping Voltage (V_C): When a transient occurs, the clamping voltage is the maximum voltage that appears across the diode. For this model, it is typically around 50V at a specified peak pulse current.
• Peak Pulse Power (P_PP): The diode can handle a peak pulse power of 400W, which indicates its ability to absorb high-energy transients without failure.
• Peak Pulse Current (I_PP): The maximum peak pulse current it can withstand is around 30A, which is crucial for protecting circuits from high current surges.

Thermal Characteristics:

• Operating Temperature Range: The device can operate within a temperature range of -55°C to +150°C, making it suitable for various environmental conditions.
• Junction Capacitance: The junction capacitance is typically low, which helps in maintaining signal integrity in high-speed applications.

Applications:

The SMAJ33A-E3/61 is commonly used in:

• Automotive electronics
• Telecommunications equipment
• Consumer electronics
• Industrial control systems
• Any application where voltage transients can occur, such as inductive loads or lightning strikes.

Compliance and Standards:

• The device is compliant with various industry standards, ensuring reliability and performance in critical applications.
• It is also RoHS compliant, indicating that it is free from hazardous substances.

Summary:

The SMAJ33A-E3/61 from Vishay is a robust and reliable transient voltage suppressor diode, ideal for protecting sensitive electronic components from voltage spikes.
