The MMBZ5253B is a Zener diode designed for voltage regulation and protection applications. It features a nominal Zener voltage of 25V with a tolerance of ±5%, making it suitable for precise voltage clamping and reference circuits. The device can dissipate up to 350mW of power, ensuring reliable operation under typical load conditions.
Electrical characteristics include a maximum Zener impedance of 35Ω at 20mA test current, a forward voltage drop of 0.9V maximum at 10mA, and a reverse leakage current of 100nA maximum at 19V. The diode operates over a junction temperature range of -55°C to +150°C, allowing use in harsh environments.
The MMBZ5253B is housed in a compact SOT-23-3 surface-mount package (also available as TO-236-3 or SC-59), making it ideal for space-constrained designs. It is part of the MMBZ5221B-MMBZ5257B series from On Semiconductor (formerly Fairchild Semiconductor).
