STMicroelectronics SM15T33A-TR Transil™ TVS Diode

The SM15T33A-TR from STMicroelectronics is a state-of-the-art Transil™ transient voltage suppressor (TVS) diode designed to protect sensitive electronics from voltage transients induced by system-level events such as load dump and jump start. This robust component is a part of STMicroelectronics' SM15T series, which is well-regarded for its ability to safeguard circuits by clamping the overvoltage to a safe level while ensuring the integrity of the electronic system.

With a stand-off voltage of 33V, the SM15T33A-TR is particularly suitable for protecting 28V bus lines against surges defined in ISO 7637-2. Its peak pulse power dissipation is an impressive 1500W (10/1000μs), which helps to prevent damage to the protected component by shunting excess energy away in the event of a surge or electrical spike.

The device comes in a robust DO-214AB (SMC) package, which not only offers a compact footprint but also ensures a high level of mechanical durability and thermal conductivity. The SM15T33A-TR is capable of handling repetitive transients thanks to its excellent load dump test resilience, and it features a junction temperature range from -55°C to +150°C, making it suitable for a wide range of industrial and automotive applications.

Moreover, the SM15T33A-TR is characterized by a low leakage current and a fast response time, ensuring that the device reacts quickly to transient events without significantly affecting the normal operation of the circuit. This TVS diode is also RoHS compliant and adheres to the AEC-Q101 standards for automotive electronic components, reflecting its reliability and quality assurance for demanding automotive environments.

Whether it's for automotive electronics, power supply protection, or sensitive data line shielding, the SM15T33A-TR from STMicroelectronics is an excellent choice for engineers looking for a high-performance, reliable transient voltage suppression solution.
