The SMC30J48CA is a robust transient voltage suppression (TVS) diode from STMicroelectronics, designed to protect sensitive electronic equipment from voltage transients induced by system inductance or lightning. This component is part of the Transil series, which are bidirectional TVS diodes, providing high overvoltage protection by clamping action. Its unique design enables it to respond to overvoltages faster than other varistor or zener-type transient suppressors.
Key Features
- Stand-off voltage: 48V
- Peak pulse power: 3000 W (10/1000 µs)
- Low clamping factor
- Fast response time
- Low incremental surge resistance
- Operating Junction Temperature range: -55°C to +150°C
- Package: SMC (DO-214AB)
Applications
The SMC30J48CA is ideal for protecting voltage sensitive devices such as power supplies, automotive electronics, and other vulnerable circuits. Its ability to handle high energy transients makes it suitable for use in locations with a high risk of lightning strikes or switching surges.
Performance and Protection
With its high surge capability, the SMC30J48CA can effectively absorb potentially damaging energy spikes without sustaining damage itself, ensuring the protected component remains safe. The device's low clamping voltage ensures that the energy is not passed on to the protected circuit, thus preventing stress and potential failure of the electronic components.
Reliability and Quality
STMicroelectronics is known for its commitment to high standards of quality and reliability, and the SMC30J48CA is no exception. It is manufactured to withstand harsh environmental conditions and is characterized by its robustness and longevity, making it a reliable choice for critical applications.
Environmental Compliance
The SMC30J48CA complies with various environmental standards, including RoHS and REACH, reflecting STMicroelectronics' dedication to environmental sustainability and the production of eco-friendly products.
