The SM15T24A is a robust Transil™ transient voltage suppressor (TVS) diode designed and manufactured by STMicroelectronics. This TVS diode is engineered to protect sensitive electronic equipment from voltage transients induced by system inductance, lightning, and other transient voltage events.
Key Features
- Stand-off Voltage: The device offers a stand-off voltage of 24V, which is the maximum voltage that the diode can withstand without conducting in its off state.
- Peak Pulse Power: It can handle peak pulse power dissipation of 1500W (10/1000µs), ensuring protection against high energy transients.
- Clamping Voltage: With a clamping voltage of 38.9V, the SM15T24A ensures that any transient above this threshold is effectively clamped, providing a safe voltage level to the protected components.
- Low Leakage Current: The device exhibits low leakage current, minimizing power loss when the diode is in the standby state.
- Fast Response Time: The TVS diode provides a fast response time to transient events, typically in the order of picoseconds, offering immediate protection upon detection of a surge.
- Package: Available in an industry-standard DO-214AB (SMC) package, it is suitable for high-density circuit board designs.
Applications
The SM15T24A is well-suited for a variety of applications where transient voltage protection is critical. It is commonly used in:
- Automotive systems
- Industrial applications
