SZ1SMB5947BT3G Description

Short technical summary and product information.

The On Semiconductor SZ1SMB5947BT3G is a single Zener diode designed for voltage regulation and protection applications. It features a nominal Zener voltage of 82V with a tolerance of ±5%, ensuring precise voltage clamping. The device is rated for a continuous power dissipation of 3W, making it suitable for moderate power handling requirements.

 

Key electrical characteristics include a maximum impedance (Zzt) of 160 Ω and a reverse leakage current of 1 µA at 62.2V. The forward voltage is specified at 1.5V when tested at 200 mA. The diode operates over a wide temperature range from -65°C to 150°C, providing robust performance in demanding environments.

 

The SZ1SMB5947BT3G is housed in a DO-214AA (SMB) surface mount package, which is compatible with standard SMD assembly processes. The SMB package offers a compact footprint suitable for space-constrained PCB designs while providing adequate thermal dissipation for the 3W power rating.
