Overview
The MMBZ5230BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It features a nominal Zener voltage of 4.7 V with a tolerance range of 4.47 V to 4.94 V at a test current of 20 mA. The device has a maximum power dissipation of 200 mW and a maximum reverse leakage current of 5.0 µA at 2.0 V. Electrical characteristics include a maximum Zener impedance of 19 Ω at the test current and 1900 Ω at a knee current of 0.25 mA. The component operates within a temperature range of -65°C to +150°C.
Feature Summary
- Dual isolated Zener configuration integrated into an ultra-small surface mount package
- Planar die construction designed for automated assembly processes
- Lead-free plating with matte tin finish annealed over Alloy 42 leadframe
Applications
- Voltage reference circuits requiring dual independent references
- Clamping applications in signal processing paths
- Protection circuits for sensitive electronic components
Procurement Notes
Verify the specific ordering suffix against official manufacturer documentation to confirm packaging details. Confirm that the requested part number matches the exact electrical specifications required for the design. Ensure compliance with environmental standards such as RoHS if applicable to the project requirements.
Selection Notes
Select this component when two independent voltage regulation points are needed within a single compact footprint. Consider the 200 mW power dissipation limit and thermal resistance when designing the PCB layout. Verify that the 4.7 V breakdown voltage aligns with the circuit's operational requirements.
Part Context
This component belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltage options ranging from 2.4 V to 39 V in the same SOT-363 package. This allows designers to standardize on a single package type while selecting different voltage ratings for diverse application needs.
Replacement Considerations
Direct substitutes within the same series include other MMBZ52xxBS variants with different Zener voltages if the voltage requirement changes. Cross-referencing with equivalent dual Zener arrays in SOT-363 packages from other manufacturers requires careful verification of pinout compatibility and electrical parameters.
