Description

MMBZ5242BLT1G is a surface‑mount Zener diode (12 V) from On Semiconductor’s MMBZ series. Key points:
- Zener voltage: nominally 12 V (reverse‑biased for regulation/clamping)
- Power rating: about 0.5 W
- Package: MMBZ series, RoHS-compliant SMD (indicated by the LT1G suffix)
- Tolerance: B = ±5%
- Polarity: cathode marked (band) side; use in reverse bias for regulation or transient suppression
- Typical uses: voltage regulation, reference/clamping, overvoltage protection in compact circuits
- Temp range: wide operating range (typical for MMBZ diodes)
In short: a small 12 V Zener diode for tight, compact voltage regulation or protection in SMD designs.

Features

MMBZ5242BLT1G features (summary):
- 12 V Zener diode (reverse breakdown around 12 V; nominal Vz ~12 V)
- 0.5 W power rating (surface-mount)
- Unidirectional Zener for regulation, reference, and protection
- Tolerance: typically ±5%
- Wide operating temperature: generally -55°C to +150°C
- RoHS compliant; small SMD package (tape-and-reel LT1G)
- 2-terminal device, suitable for compact regulator/designal protection circuits

Package

SOD-123 surface-mount package (lead-free). The T1G suffix indicates RoHS-compliant tape-and-reel packaging.

Pinout

- Pin count: 2 pins
- Function: Unidirectional Zener diode used for voltage regulation/clamping (12 V Zener in a small SMD package).

Manufacturer

- Manufacturer: ON Semiconductor (Onsemi).
- What kind of company: A US-based multinational semiconductor company that designs, manufactures, and markets silicon-based integrated circuits and discrete components (diodes, transistors, power management, sensors) for automotive, industrial, and consumer markets.

Application

- 12 V Zener diode for low-power regulation and voltage references
- Shunt regulation of DC rails
- Clamping and transient protection for sensitive inputs
- Surge/overvoltage protection in consumer electronics and battery-powered devices
