1SMA5919BT3 Description

Short technical summary and product information.

The 1SMA5919BT3 is a 5.6V Zener diode from ON Semiconductor, part of the 1SMA59xxBT3 series of 1.5 Watt plastic surface mount Zener voltage regulators. It offers a nominal Zener voltage of 5.6V with a ±5% tolerance and a maximum forward voltage of 1.5V at 200 mA.

 

With a power dissipation of 1.5W at a lead temperature of 75°C (zero lead length), this device is suitable for voltage regulation and overvoltage protection in moderate power applications. The Zener impedance is 2 Ω at the test current, and reverse leakage current is limited to 2.5 µA at 3V. The operating temperature range spans -65°C to 150°C.

 

The diode is housed in a DO-214AC (SMA) surface mount package, featuring a low profile and flat handling surface for accurate placement. It is ESD rated Class 3 (>16 kV) per the Human Body Model and has a flammability rating of UL 94 V-0.
