Overview
The MMBZ5239BS-7 is a dual isolated Zener diode array manufactured by Diodes Incorporated in an SOT-363 surface mount package. It features a nominal Zener voltage of 9.1V with a tolerance range of 8.65V to 9.56V at a test current of 0.25mA. The device has a maximum power dissipation of 200mW and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance of 10Ω at the test current and a maximum reverse leakage current of 3.0μA at 7.0V. The forward voltage is specified as 0.9V at a forward current of 10mA.
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 and RoHS compliant manufacturing with green molding compound options
Applications
- Voltage reference circuits requiring compact dual-channel regulation
- Signal clamping and protection in portable electronic devices
- General purpose voltage stabilization in space-constrained PCB layouts
Procurement Notes
Verify the specific ordering suffix '-7-F' corresponds to the tape and reel packaging format containing 3000 units per reel. Confirm that the component meets the required environmental standards, specifically checking for lead-free plating and compliance with J-STD-020D moisture sensitivity level 1 requirements before finalizing procurement orders.
Selection Notes
Select this component when a dual isolated Zener solution is needed in an SOT-363 footprint. Ensure the application current does not exceed the 0.25mA test condition for accurate voltage regulation. Verify thermal resistance constraints, as the junction-to-ambient thermal resistance is 625°C/W, necessitating adequate board layout for heat dissipation under continuous operation.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series of surface mount Zener diodes. All variants in this family share the same SOT-363 package and 200mW power rating but differ in their nominal Zener voltage breakdown points. The MMBZ5239BS specifically provides the 9.1V breakdown characteristic within this standardized lineup.
Replacement Considerations
Direct replacement parts must match the SOT-363 package and 9.1V dual Zener specification. Verify electrical parameters such as impedance and leakage current against the original datasheet to ensure circuit compatibility without redesigning the surrounding components.
