The 1SMA5939BT3G is a 39V Zener diode from the 1SMA59xxBT3G series manufactured by onsemi. It offers a nominal Zener voltage of 39V with ±5% tolerance, a maximum power dissipation of 1.5W, and a typical impedance of 45Ω. Reverse leakage current is specified as 500 nA at 29.7V, and forward voltage is 1.5V at 200mA.
The device is housed in a DO-214AC (SMA) surface mount package, designed for automatic placement and reflow soldering. It operates over a junction temperature range of -65°C to 150°C and is Pb-Free. The series also features ESD rating of Class 3 (>16 kV) per Human Body Model, making it robust for various applications.
This Zener diode is suitable for voltage regulation, overvoltage protection, and general reference applications in power management circuits. It is RoHS3 compliant and has an MSL rating of 1 (Unlimited). While compliance data is noted, verification from manufacturer documentation is recommended for critical designs.
The nominal Zener voltage is 39V with a tolerance of ±5%.
The maximum power dissipation is 1.5W (at lead temperature 75°C).
The maximum forward voltage is 1.5V at 200mA forward current.
The package is DO-214AC (SMA), suitable for surface mount mounting.
The operating temperature range is -65°C to 150°C.
The reverse leakage current is 500 nA at 29.7V reverse voltage.
The component is indicated as RoHS3 Compliant, though this data is unverified and should be confirmed with the manufacturer.
