- Temperature range: -55°C to +125°C
- Applications: input protection, shunt regulation, voltage references, and transient suppression
For exact specs (dynamic impedance, knee current, leakage, and maximum reverse voltage), consult the MMBZ5242B datasheet from ON Semiconductor.
Equivalent
Features
- Nominal Zener voltage: 12 V (MMBZ5242B family)
- Power rating: 0.5 W (25°C)
- Tolerance: ±5%
- Temperature range: -55°C to +125°C
- RoHS compliant, lead-free
- Tape & reel packaging (LT1G variant)
- Used for voltage regulation, reference, and surge/overvoltage protection in compact SMT designs.
Pinout
- Function: Unidirectional Zener diode (voltage clamp/regulator) used for overvoltage protection and voltage regulation in SMT circuits.
Manufacturer
Company type: American multinational semiconductor company that designs and manufactures discrete and integrated devices (e.g., diodes, transistors, power-management ICs, sensors) for automotive, industrial, consumer electronics, and communications markets. HQ in Phoenix, Arizona; public company and major supplier of energy-efficient components.
Application
- Shunt regulator/reference: simple, low-power voltage reference and regulator circuits.
- Voltage clamping/protection: protect microcontrollers, sensors, and logic inputs from overvoltage.
- Rail protection: clamp and stabilize 12 V power rails in consumer, automotive, and telecom equipment.
- Biasing/level-shifting networks: establish reference levels in analog front ends.
- Transient/overvoltage protection in small-signal paths where a modest, fixed clamp is acceptable.
Note: choose when a fixed ~12 V clamp/reference suits the design’s accuracy and power budget.
