SMA5127** is a surface-mount TVS (Transient Voltage Suppressor) diode designed for protecting sensitive electronics from voltage transients and electrostatic discharge (ESD).

The SMA5127 is a surface-mount TVS (Transient Voltage Suppressor) diode designed for protecting sensitive electronics from voltage transients and electrostatic discharge (ESD). Below are its key specifications, descriptions, and features:

Manufacturer:

  • Bourns (primary manufacturer)

Specifications:

  • Peak Pulse Power (PPP): 400W (8/20µs waveform)
  • Breakdown Voltage (VBR): 27V (min)
  • Standoff Voltage (VRWM): 22V
  • Clamping Voltage (VC): 36.6V (at 10A)
  • Maximum Reverse Leakage Current (IR): 1µA (at VRWM)
  • Operating Temperature Range: -55°C to +150°C
  • Capacitance (Typical): Low (pF range, suitable for high-speed data lines)
  • Package: SMA (DO-214AC) surface-mount

Descriptions:

  • Function: Provides transient voltage suppression for circuits vulnerable to ESD, lightning, and other voltage spikes.
  • Applications: Used in telecommunications, automotive, industrial controls, and consumer electronics for protecting data lines, power supplies, and I/O ports.
  • Compliance: Meets IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT), and IEC 61000-4-5 (Surge) standards.

Features:

  • Fast Response Time: Reacts to transients in nanoseconds.
  • Low Clamping Voltage: Limits voltage spikes to safe levels.
  • High Surge Capability: Handles high transient currents.
  • RoHS Compliant: Lead-free and environmentally friendly.
  • Bi-directional Protection: Guards against both positive and negative voltage transients.

This component is widely used for ESD protection in USB ports, HDMI lines, and power supply circuits. For exact datasheet details, refer to the manufacturer's documentation.
