BZG05C4V3-M3-08 Description

Short technical summary and product information.

The Vishay BZG05C4V3-M3-08 is a 4.3 V Zener diode from the BZG05C-M series, designed for voltage stabilization applications. It offers a nominal zener voltage of 4.3 V with a tolerance of ±6.98%, and a maximum power dissipation of 1.25 W when mounted on standard epoxy-glass PCB with a junction-to-ambient thermal resistance below 100 K/W.

This device features a low maximum zener impedance of 13 Ω at a test current of 50 mA, ensuring stable voltage regulation. It also provides a non-repetitive peak surge power capability of 60 W for transient protection. The diode is housed in a compact DO-214AC (SMA) surface mount package, weighing 64 mg, and is suitable for wave and reflow soldering with a peak solder temperature of 260 °C.

The BZG05C4V3-M3-08 is RoHS-compliant and halogen-free, making it suitable for environmentally conscious designs. It is a commercial-grade component, with an AEC-Q101 qualified variant (HM3 suffix) available for automotive applications.
