Descripción general

Description

MMSZ5257BT1G is a small-signal, surface-mount Zener diode from the MMSZ5xxx family. It provides a fixed Zener voltage for regulation, reference, or overvoltage protection in low-power circuits. The “BT1G” suffix indicates RoHS-compliant packaging (tape-and-reel) in a compact SOD-123 style package. The diode is operated in reverse bias to achieve its breakdown voltage; the cathode should be tied to the higher potential and the anode to ground. The exact Zener voltage (Vz) and tolerance are specified in the datasheet for this variant (typically ±5% for the B tolerance). Power rating is around 0.5 W in the SOD-123 package. For exact Vz and electrical characteristics, consult the manufacturer’s datasheet or distributor listings.

Features

Here are the typical features of MMSZ5257BT1G:
- Fixed Zener diode for voltage regulation and clamping
- Zener voltage: 5.7 V (nominal)
- Power rating: 0.5 W (SMD Zener)
- Package: MMSZ series, small surface-mount (SMD) package
- Tolerance: ±5% (VZ)
- Temperature range: -55°C to +125°C
- RoHS compliant; available in tape-and-reel packaging
Common uses: voltage references, transient/clamp protection, simple regulators in low-power circuits. For exact packaging (SOD-123/SOD-323) and tolerance details, refer to the datasheet.

Package
