The PTZTE257.5B is a Zener diode from ROHM Semiconductor's PTZ series. It has a nominal Zener voltage of 7.9V with a range of 7.5V to 8.4V and a tolerance of ±6%. The maximum power dissipation is 1W, allowing use in voltage regulation and surge absorption applications. The diode features a low maximum dynamic impedance (Zzt) of 4Ω at a test current of 20mA. Reverse leakage current is limited to 20µA maximum at 4V reverse voltage. Constructed with silicon epitaxial planar technology, it is designed for surface mount assembly in the compact PMDS package (DO-214AC / SMA). The junction temperature rating is 150°C maximum, with a storage temperature range of -55°C to +150°C. This component is suitable for general voltage regulation, clamping, and transient suppression in various electronic circuits.
