MMBZ5235BS-7-F

Overview

The MMBZ5235BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, designed for surface mount applications. It features a nominal Zener voltage of 6.8 V with a tolerance range of 6.46 V to 7.14 V at a test current of 20 mA. The device operates within a power dissipation limit of 200 mW and maintains a maximum reverse leakage current of 3 µA at 5.0 V. Electrical characteristics include a maximum Zener impedance of 5 Ω at the test current and 750 Ω at a lower current of 0.25 mA. The component is housed in an SOT-363 package and supports an operating temperature range from -65 °C to +150 °C.

Feature Summary

Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm packaging details. Confirm compliance requirements such as RoHS status and moisture sensitivity levels prior to integration. Ensure that the procurement source provides valid traceability data consistent with the original manufacturer's specifications for quality assurance purposes.

Selection Notes

Select this component when dual isolated Zener functionality is required in a minimal footprint. The SOT-363 package accommodates high-density board layouts. Evaluate thermal resistance and power derating curves to ensure operation remains within the specified junction temperature limits under expected load conditions.

Part Context

This part belongs to the MMBZ5221BS through MMBZ5259BS series, which encompasses various Zener voltage options within the same physical package. The series utilizes a standardized SOT-363 housing to provide design flexibility across different voltage requirements while maintaining consistent mechanical and thermal characteristics for manufacturing efficiency.

Replacement Considerations

Direct substitutes within the same series include MMBZ5235BSC-7-F or other variants sharing identical electrical parameters and pinout configurations. Verify that any replacement maintains the dual isolated architecture and compatible package dimensions for seamless PCB integration.
