STMicroelectronics 1-Element Uni-Directional TVS Diode 1.5 kW Surface Mount SMB Package SMB15F48A

STMicroelectronics SMB15F48A is a 1-element uni-directional Transient Voltage Suppressor (TVS) diode specifically designed to protect sensitive electronic circuits from transient voltage surges and spikes. This device utilizes planar technology for high junction temperature endurance up to 175°C and low leakage to ensure long-term operational reliability in demanding environments.

The diode features a surface mount SMB package with two pins, making it easy to integrate into compact PCB layouts commonly found in industrial, automotive, telecommunications, and consumer electronic applications. Its uni-directional configuration is ideal for circuits where protection is required in one polarity.

With a rated peak pulse power dissipation of 1.5 kW and a peak pulse current of 20A, the SMB15F48A effectively clamps voltage surges up to a clamping voltage of 77.4 V while ensuring minimal leakage current of 1μA during regular operation. Its breakdown voltage of 58.8 V and maximum stand-off voltage of 64 V guarantee precise protection thresholds.

The device operates reliably within a broad temperature range from -55°C to +175°C, making it suitable for rugged applications exposed to wide temperature variations. Compact physical dimensions - 3.95 mm length, 5.6 mm width, and 1.1 mm height - enable deployment in space-constrained systems.
