SMAJ58A

The SMAJ58A, manufactured by Littelfuse Inc., is a surface-mount Transient Voltage Suppression (TVS) diode designed to shield sensitive electronic equipment from sudden voltage spikes caused by lightning strikes, power surges, and other transient events. Here's a breakdown of its key characteristics:

Technical Specs:

• Peak Pulse Power: 400W for a pulse duration of 10μs (microseconds) and 1000μs (milliseconds)
• Clamping Voltage: 93.6V (maximum voltage the diode will allow to pass through before clamping it)
• Peak Pulse Current: 4.3A (maximum current the diode can handle during a transient event)
• Reverse Leakage Current: 1μA (typical amount of current flowing through the diode in the reverse direction when no transient event is present)
• Response Time: Less than 1.0 picoseconds (ps) (incredibly fast, effectively instantaneous)
• Package: DO-214AC (SMA), a small, rectangular surface-mount package with gull-wing leads for easy soldering

Key Features:

• High Peak Pulse Power: Effectively absorbs and diverts large bursts of transient energy, protecting valuable circuitry.
• Fast Response Time: Reacts to voltage spikes almost instantaneously, minimizing damage before it can occur.
• Low Leakage Current: Minimal drain on the system during normal operation.
• Surface-Mount Packaging: Easy to integrate into printed circuit boards for compact and efficient designs.
• Wide Range of Applications: Ideal for protecting I/O interfaces, VCC bus lines, and other vulnerable circuits in telecom, computer, industrial, and consumer electronics.

In simpler terms: Imagine the SMAJ58A as a tiny bodyguard for your electronics. It stands guard, ready to jump in and deflect any unexpected voltage attacks that could harm your delicate circuits. It's fast, powerful, and doesn't get in the way during normal operation.
