1SMB5949BT3 Description

Short technical summary and product information.

The 1SMB5949BT3 is a 100V Zener diode from On Semiconductor's 1SMB59xxBT3 series, designed for voltage regulation in surface mount applications. It offers a nominal Zener voltage of 100V with a tolerance of ±5% and a maximum Zener impedance of 250 Ω at the test current.

 

This diode can dissipate up to 3W of power (when measured at a lead temperature of 75°C) and features a maximum forward voltage of 1.5V at 200mA. The reverse leakage current is limited to 1 µA at 76V. It is rated for an operating temperature range of -65°C to 150°C.

 

The device is housed in a DO-214AA (SMB) surface mount package with modified L-bend leads, suitable for top-side or bottom-side circuit board mounting. It is available in tape and reel packaging with a standard quantity of 2500 pieces. The part has an ESD rating of Class 3 (>16 kV) per the Human Body Model.
