Manufacturer: Vishay General Semiconductor - Diodes Division

Categories: Single Zener Diodes

Quality Control: Learn More

The Vishay General Semiconductor - Diodes Division MMBZ5249C-HE3-18 is a Zener diode designed for precision voltage regulation applications. Featuring a nominal Zener voltage (Vz) of 19 V with a tight ±2% tolerance, this component offers stable performance. Its 225 mW power dissipation capability and 23 Ohms maximum Zener impedance (Zzt) make it suitable for various power management circuits. The device operates across a wide temperature range of -55°C to 150°C. Packaged in a SOT-23-3 (TO-236-3, SC-59) surface-mount configuration, it is supplied on tape and reel. This AEC-Q101 qualified diode exhibits a low reverse leakage current of 100 nA at 14 V. Its automotive grade qualification indicates suitability for demanding vehicle electronic systems, as well as industrial and consumer electronics where reliable voltage clamping is required.
