SMAJ40CA

The SMAJ40CA from Bourns, Inc. is a Transient Voltage Suppressor (TVS) diode in a Surface Mount DO-214AC (SMA) package. It's designed to protect sensitive electronic circuits from voltage spikes and transient overvoltages. Here's a detailed breakdown of its features:

Key Specifications:

• Standoff Voltage: 64.5V (maximum voltage the diode can withstand before breaking down)
• Peak Pulse Current (IPP): 6.2A (maximum surge current the diode can handle for a short duration)
• Peak Non-Repetitive Surge Current (ISM): 40A (maximum surge current the diode can handle for a single event)
• Power Dissipation: 400W (maximum power the diode can dissipate without overheating)
• Reverse Leakage Current: 1µA (typical leakage current when the diode is reverse-biased)
• Clamping Voltage: Below 88V (typical voltage at which the diode conducts during a transient event)
• Reverse Recovery Time: 4ns (time it takes for the diode to switch from conducting to blocking after a transient event)
• Package: DO-214AC (SMA) - a small, surface-mount package with a black, cylindrical body and gull-wing leads

Applications:

• Protecting sensitive electronics from lightning strikes, ESD (electrostatic discharge), and other transient voltage spikes
• Used in power supplies, chargers, communication equipment, consumer electronics, and industrial control systems
• Ideal for protecting low-voltage circuits due to its relatively low standoff voltage

Advantages:

• High-speed response: Can clamp transient voltages in picoseconds, protecting sensitive circuits from damage
• Compact size: Surface-mount package makes it suitable for high-density PCB layouts
• Lead-free and RoHS compliant: Meets environmental regulations

Additional Notes:

• Bourns offers a variety of SMAJ series TVS diodes with different standoff voltages and current ratings to suit different application needs.
• It's important to choose the right TVS diode based on the expected voltage spikes and current levels in your circuit.
• You can find detailed specifications and application information in the SMAJ40CA datasheet from Bourns.
