The SMC30J48A is a state-of-the-art Transil™ transient voltage suppressor (TVS) diode designed by STMicroelectronics. This robust diode is specifically engineered to protect sensitive electronic equipment from voltage transients induced by load dump and other transient voltage events. With its SMC (DO-214AB) package, it is an ideal choice for surface mount applications.

Key Features

• Stand-off voltage: 48 V, making it suitable for a wide range of applications where this voltage level is common.
• Peak pulse power: 3000 W (10/1000 µs surge), providing reliable protection against high energy transients.
• Clamping voltage: Low clamping voltage ensures that the protected components are shielded from the damaging effects of transients.
• Low leakage current: Ensures minimal power loss when the device is in standby mode, enhancing overall efficiency.
• High surge capability: With its robust surge handling capacity, it can withstand multiple surge events without degradation.
• Junction temperature range: -55°C to 150°C, which allows for operation in extreme environmental conditions.
