Frequently Asked Questions
What is the Zener voltage and dynamic impedance of the UDZSTFTE-175.6B?
The UDZSTFTE-175.6B has a nominal Zener voltage of 5.6V with a maximum dynamic impedance of 60Ω and knee impedance up to 200Ω. These parameters ensure stable voltage clamping performance across a range of operating currents in voltage regulation and protection circuits.
Which PCB package does the UDZSTFTE-175.6B use, and how small is its footprint?
The UDZSTFTE-175.6B is packaged in the SC-90 (SOD-323) 2-pin SMT package, which has a body size of approximately 1.7mm x 1.25mm. This ultra-compact footprint is well-suited for space-constrained designs such as wearables, smartphones, and miniaturized industrial protection circuits.
For which protection applications is the UDZSTFTE-175.6B Zener diode best suited?
The UDZSTFTE-175.6B is ideal for clamping overvoltage transients on 5V logic rails, protecting microcontroller GPIO pins rated at 5V, and providing stable reference voltages in analog front-end circuits. Its 5.6V breakdown and high-reliability construction suit both consumer and industrial environments.
How does the ROHM UDZSTFTE-175.6B compare to through-hole Zener alternatives for modern PCB designs?
Compared to DO-35 or DO-41 through-hole Zener diodes, the UDZSTFTE-175.6B in SOD-323 occupies roughly 70% less PCB area and supports automated SMT reflow at 260°C peak temperature, reducing assembly cost while delivering equivalent 5.6V regulation and at least 200mW power dissipation in standard application conditions.
