概要
Description
SZMMSZ5246BT1G is a surface-mount Zener diode (MMSZ5246B family) used for voltage regulation and clamping. Key points:
- Zener voltage: nominally 16 V (tolerances per datasheet).
- Power rating: about 0.5 W (SOD-123 package).
- Package/packaging: SMD MMSZ- series; T1G indicates Tape & Reel RoHS package.
- Typical uses: simple low-power voltage regulation, over/under-voltage protection, and reference/clamping in digital and analog circuits.
- Characteristics to check: Vz tolerance, reverse leakage, Zzt (dynamic impedance), and recommended test current (Izt).
- Availability: widely stocked from major distributors; compatible with common 16 V clamping/regulation designs.
If you need a different Zener voltage, there are other MMSZ524xB variants in the same family.
