MMBZ5241BS-7-F

Overview

The MMBZ5241BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 surface-mount package. It provides two independent Zener channels within a single ultra-small footprint. The nominal Zener voltage for each channel is 11 V, with a tolerance range of 10.45 V to 11.55 V at a test current of 20 mA. Maximum power dissipation is rated at 200 mW, and the device supports an operating temperature range from -65 °C to +150 °C. Electrical specifications include a maximum Zener impedance of 22 Ω and a maximum reverse leakage current of 2 μA.

Feature Summary

• Dual isolated Zener channels integrated into a single 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 compact dual-channel regulation
• Signal clamping applications in space-constrained PCB layouts
• Protection circuits utilizing dual independent breakdown voltages

Procurement Notes

Verify component authenticity through authorized distribution channels. Confirm RoHS compliance status and date code markings against the manufacturer's documentation. Ensure storage conditions adhere to moisture sensitivity level 1 requirements per J-STD-020D standards to prevent package damage during reflow soldering.

Selection Notes

Select this component when dual independent Zener regulation is required in minimal board space. The SOT-363 package offers a smaller footprint compared to discrete dual packages. Verify that the 200 mW power dissipation rating meets thermal requirements for the specific application environment.

Part Context

This part belongs to the MMBZ5221BS through MMBZ5259BS series of 200mW surface mount Zener diodes. All devices in this family share identical mechanical dimensions and packaging characteristics while varying in Zener voltage ratings. The series utilizes consistent planar die construction technology across all voltage variants.

Replacement Considerations

Direct substitutes must match the SOT-363 package and dual isolated configuration. Verify equivalent electrical parameters including 11V nominal voltage, 200mW power rating, and 22Ω impedance. Cross-reference marking codes KC1 for visual identification compatibility.
