Frequently Asked Questions
What is the Zener voltage and power rating of MMSZ5252B-E3-08?
The MMSZ5252B-E3-08 has a Zener voltage of 24 V with ±1% tolerance and a maximum power dissipation of 500 mW. This combination makes it suitable for precision voltage regulation in low-power circuits where a stable 24 V reference is needed.
Which PCB designs benefit most from the SOD-123 package of MMSZ5252B-E3-08?
The SOD-123 2-pin SMD package measures approximately 2.8 mm × 1.8 mm, making MMSZ5252B-E3-08 an excellent choice for compact, high-density PCB layouts in portable electronics, wearables, and miniaturized industrial modules where board space is at a premium.
How does MMSZ5252B-E3-08 compare to a higher-tolerance Zener diode for voltage reference applications?
With a maximum dynamic impedance of 33 Ω and a knee impedance of up to 600 Ω, MMSZ5252B-E3-08 provides stable regulation suitable for many reference and clamping tasks. For precision below ±1%, a voltage reference IC may be preferable, but for 24 V clamping and protection at up to 500 mW, this Vishay Zener diode is a cost-effective single-element solution.
