Overview
The MMBZ5243BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated in an SOT-363 surface-mount package. It features a nominal Zener voltage of 13 V with a tolerance range of 12.35 V to 13.65 V at a test current of 9.5 mA. The device has a maximum power dissipation of 200 mW and a maximum reverse leakage current of 0.5 µA at 9.9 V. Electrical characteristics include a maximum Zener impedance of 13 Ω at the test current and 600 Ω at a lower current of 0.1 mA. The component operates within a temperature range of -65 °C to +150 °C.
Feature Summary
- Dual isolated Zener configuration housed in an ultra-small SOT-363 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 compact electronic designs
- Protection circuits utilizing dual isolated channels
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, particularly the dual isolated configuration and SOT-363 footprint dimensions.
Selection Notes
Select this component when a dual Zener solution is needed in a minimal footprint. Ensure the circuit design accommodates the 200 mW power dissipation limit and the specific impedance characteristics at the operating current. Verify thermal management requirements given the small package size and thermal resistance values.
Part Context
This component belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series offers various Zener voltage options within the same SOT-363 package format, allowing for consistent board layout across different voltage reference designs while maintaining dual isolation capabilities.
Replacement Considerations
Direct replacements must match the SOT-363 package, dual isolated configuration, and 13 V nominal voltage. Verify that alternative manufacturers provide equivalent electrical parameters, specifically the 200 mW power rating and leakage current limits.
