The SM15T30A is a Transil™ diode designed and manufactured by STMicroelectronics, a global leader in semiconductor solutions. This transient voltage suppressor (TVS) diode provides high surge protection in a compact package, making it an ideal choice for safeguarding sensitive electronic components against voltage transients induced by system-level events such as load dump and jump start in automotive applications, as well as lightning and switching operations in industrial systems.

Key Features

• Stand-off Voltage: The SM15T30A has a stand-off voltage of 30V, which allows it to remain non-conductive under normal operating conditions, thereby avoiding any impact on the normal operation of the protected circuit.
• Peak Pulse Power: With a peak pulse power dissipation of 1500W (10/1000μs), it can handle significant power surges, ensuring robust protection for sensitive circuits.
• Clamping Voltage: The device clamps at a maximum voltage of 48.4V when subjected to a peak impulse current, thereby limiting the voltage spike to a safe level for semiconductor components.
• Package: Available in an SMB (DO-214AA) surface-mount package, the SM15T30A is designed for easy integration into a variety of PCB layouts.
• Temperature Range: It operates over a wide temperature range from -55°C to +150°C, making it suitable for harsh environmental conditions.
• Compliance: This component complies with the IEC 61000-4-2 and IEC 61000-4-5 standards, ensuring compatibility with electrostatic discharge (ESD) and surge protection requirements.

Applications

The SM15T30A is versatile and can be used in a range of applications. Its primary use is to protect voltage-sensitive components from electrical over-stress (EOS) and electrostatic discharge (ESD) in automotive systems. It is also well-suited for power supply protection, AC/DC applications, and industrial systems where surge protection is critical.
