TPI8011N

TPI8011N Description

The TPI8011N from STMicroelectronics is a high-performance thyristor surge protector designed for surface-mount applications. As part of the TPI series, it offers robust overvoltage protection with a breakover voltage of 110V and a peak pulse current rating of 30A (10/1000µs), making it suitable for transient suppression in demanding environments. Its hold current (Ih) of 150mA ensures reliable latching behavior, while the single-element design simplifies integration into compact circuits. Although marked as obsolete (ECCN: OBSOLETE), it remains ROHS3 compliant and REACH unaffected, ensuring environmental compliance for legacy designs. Packaged in an 8SOIC tube, it is ideal for automated assembly processes.

TPI8011N Features

• High Surge Handling: 30A peak pulse current for robust transient suppression.
• Precise Breakover Voltage: 110V threshold ensures targeted overvoltage protection.
• Low Hold Current: 150mA (Ih) for stable latching performance.
• Surface-Mount Design: 8SOIC package enables space-efficient PCB layouts.
• Compliance: ROHS3 compliant and REACH unaffected, meeting environmental standards.
• Reliability: MSL 1 (Unlimited) moisture sensitivity ensures long-term storage stability.

TPI8011N Applications

The TPI8011N excels in transient voltage suppression (TVS) for:

• Telecommunications equipment: Protects sensitive circuitry from lightning-induced surges.
• Industrial control systems: Safeguards PLCs and sensors against voltage spikes.
• Power supplies: Enhances reliability in AC/DC converters.
• Automotive electronics: Mitigates load-dump transients in 12V/24V systems.
  Its fast response time and high surge capability make it superior to generic thyristors in high-noise environments.

Conclusion of TPI8011N

The TPI8011N is a high-reliability thyristor tailored for surge protection in critical applications. While obsolete, its 30A surge rating, 110V breakover voltage, and surface-mount compatibility ensure it remains a viable choice for legacy designs requiring robust transient suppression. Engineers seeking a compact, compliant solution for industrial or telecom systems will find it a dependable option.
