The P4SMA27A is a surface-mount transient voltage suppressor (TVS) diode manufactured by GOOD-ARK Electronics. It is designed to protect sensitive electronic components from voltage transients induced by lightning, electrostatic discharge (ESD), and inductive load switching.

Applications:

• I/O Ports
• VCC Bus Protection
• Data Lines
• Microprocessor Protection

Features:

• Surface Mount Package: SMA (DO-214AC)
• Reverse Stand-Off Voltage: 27V
• Breakdown Voltage: 30V - 33.2V
• Peak Pulse Power: 400W (10/1000μs waveform)
• Uni-directional
• Fast Response Time: Typically less than 1.0ps
• RoHS Compliant

Benefits:

• Effective Transient Protection: Clamps voltage spikes to protect downstream components.
• Fast Response Time: Quickly responds to transient events, minimizing potential damage.
• Small Footprint: Surface-mount package allows for compact designs.
• High Surge Capability: Handles high surge currents without failure.
• Increased System Reliability: Protects against damage from voltage transients, improving overall system reliability.

Additional Details:

The P4SMA27A operates over a wide temperature range, typically from -55°C to +150°C. The clamping voltage at peak pulse current is approximately 43.5V. The device is designed to meet industry standards for surge protection. The SMA package is suitable for automated assembly and reflow soldering. The low profile of the package minimizes the impact on the overall board height. This TVS diode is a reliable and cost-effective solution for protecting electronic circuits from transient voltage events. It is commonly used in automotive, industrial, and consumer electronics applications. The uni-directional configuration means it provides protection for positive polarity transients only.
