Description

MMSZ5251BT1G is a small, surface-mount zener diode from ON Semiconductor (MMSZ series). It is a 0.5 W device used to regulate or clamp voltages in compact circuits. The “5251B” family indicates a nominal zener voltage around 6.2 V, and “T1G” denotes tape‑and‑reel packaging in a standard SOD-123‑style case. Typical applications include voltage regulation, reference/clamp circuits, and protection in portable electronics. For exact values (IZT, dynamic impedance, leakage, tempco, tolerance), please consult the MMSZ5251BT1G datasheet.

Features

Here are the key features of MMSZ5251BT1G:
- Zener diode, nominal Zener voltage VZ = 5.1 V
- Power rating: 0.5 W (Ptot at 25°C)
- Package: SMD, typically in SOD-123
- Surface-mount, suitable for automated assembly
- Reverse breakdown voltage tolerance: ±5%
- Temperature range: -55°C to +150°C
- RoHS compliant, lead-free (Green/T1G packaging)
- Tape & reel packaging for automated handling
Common uses: voltage regulation, references, and transient/over-voltage protection in compact circuits.

Package

MMSZ5251BT1G uses a SOD-123 surface-mount package (RoHS, tape-and-reel variant).

Pinout

- Pin count: 2 pins (two-terminal device)
- Function: Zener diode (nominal 5.1 V) in a SMD package, used for voltage regulation/clamping (voltage reference/protection).

Manufacturer

- Manufacturer: Vishay Intertechnology, Inc.
- What kind of company: A global manufacturer of electronic components and semiconductors (discretes, passive components, sensors, and related products).

Equivalent

Do you need cross-references for the same zener voltage in the same package? If so, please confirm the voltage (likely 5.1 V) and packaging (SOD-123). I can then give exact equivalents from major vendors (e.g., Vishay, Nexperia/ON, Diodes Inc) matching MMSZ5251BT1G.
