SA5V0A

SA5V0A Description

The SA5V0A from onsemi is a unidirectional Zener-type TVS (Transient Voltage Suppression) diode designed for general-purpose protection against voltage transients in electronic circuits. With a 5V reverse standoff voltage (Typ) and a 6.4V minimum breakdown voltage, it offers robust clamping performance, limiting transient voltages to a maximum of 9.2V @ Ipp. This diode is housed in a DO-15 package and supplied in Tape & Reel (TR) for automated assembly, making it suitable for high-volume production.

SA5V0A Features

• High Peak Pulse Current: Handles 54.3A (10/1000µs), ensuring reliable protection against high-energy transients.
• Powerful Clamping Capability: 500W peak pulse power dissipation for robust surge suppression.
• Low Clamping Voltage: 9.2V maximum clamping voltage minimizes stress on protected components.
• Unidirectional Configuration: Ideal for DC circuit protection, blocking reverse polarity transients.
• Compliance & Reliability: REACH Unaffected, EAR99 ECCN, and MSL 1 (Unlimited) moisture sensitivity ensure global usability.
• Obsolete Status: While no longer in production, it remains a dependable choice for legacy designs.

SA5V0A Applications

• Consumer Electronics: Protects sensitive ICs in power supplies, USB ports, and audio/video interfaces.
• Industrial Systems: Safeguards control modules, sensors, and communication lines from ESD and inductive spikes.
• Automotive Electronics: Used in 12V/24V systems for transient suppression in infotainment or lighting circuits.
• Telecom Equipment: Shields data lines and low-voltage logic circuits from lightning-induced surges.

Conclusion of SA5V0A

The SA5V0A excels in transient voltage suppression with its high current handling, low clamping voltage, and compact DO-15 package. Though marked obsolete, its proven performance makes it a viable option for maintenance, repairs, or legacy designs requiring robust overvoltage protection. Engineers valuing reliability and cost-effectiveness in general-purpose applications will find this diode a practical solution.
