The P6KE170A-E3/54 is a Transient Voltage Suppressor (TVS) diode manufactured by Vishay. This TVS diode is designed to protect sensitive electronic components from voltage transients induced by lightning, inductive load switching, and electrostatic discharge (ESD). It is a unidirectional device, meaning it suppresses voltage spikes in one direction only.

Applications:

• Telecommunications Equipment: Protection against lightning surges.
• Industrial Control Systems: Protection from inductive switching transients.
• Consumer Electronics: ESD protection for sensitive circuits.
• Power Supplies: Transient voltage protection for power supply inputs.
• Automotive Electronics: Protection against voltage transients in automotive systems.

Features:

• Unidirectional: Suppresses voltage spikes in one direction.
• High Surge Capability: Withstands high surge currents.
• Fast Response Time: Quickly clamps transient voltages.
• Low Clamping Voltage: Protects sensitive components by limiting voltage spikes.
• RoHS Compliant: Meets environmental standards.

Benefits:

• Protection of Sensitive Components: Prevents damage from voltage transients.
• Improved System Reliability: Reduces failures due to voltage surges.
• Compliance with Safety Standards: Helps meet regulatory requirements for surge protection.
• Easy Integration: Can be easily incorporated into circuit designs.
• Long-Term Reliability: Provides consistent protection over time.

Additional Details:

The P6KE170A-E3/54 is a TVS diode available in a DO-15 package. It has a standoff voltage (working voltage) of 170V and a breakdown voltage typically around 189V. The clamping voltage is specified to limit the voltage across the protected component to a safe level during a transient event. It can handle a peak pulse power of typically 600W. The device has a fast response time, clamping voltage spikes within picoseconds. The operating temperature range is typically -55°C to +175°C. The “E3” designation indicates lead-free construction, and “/54” likely refers to a specific packaging or testing standard. This device is designed for through-hole mounting.
