Overview
The MMBZ5237BS-7-F is a dual isolated Zener diode array manufactured by Diodes Incorporated. It features an 8.2V nominal Zener voltage with a ±5% tolerance, operating within a range of 7.79V to 8.61V at a test current of 20mA. The device has a maximum power dissipation of 200mW and a maximum Zener impedance of 8Ω at the test current. It utilizes a SOT-363 surface mount package with three terminals per internal diode structure. The component supports an operating temperature range from -65°C to +150°C.
Feature Summary
- Dual isolated Zener configuration in an ultra-small surface mount package
- Planar die construction for reliable performance
- Lead-free and RoHS compliant manufacturing
Applications
- Voltage reference circuits requiring dual independent channels
- Automated assembly processes due to surface mount design
- General purpose voltage regulation in compact electronics
Procurement Notes
Verify the specific ordering suffix against official Diodes Incorporated documentation to confirm packaging details. Ensure that the procurement channel provides valid traceability for the date code marking. Confirm compliance requirements such as lead-free status if applicable to the target application environment before finalizing orders.
Selection Notes
Select this component when dual isolated Zener regulation is required in a minimal footprint. The SOT-363 package is suitable for high-density PCB layouts. Consider the 200mW power dissipation limit and thermal resistance characteristics during circuit design to ensure operation remains within safe junction temperature limits under expected load conditions.
Part Context
This part belongs to the MMBZ5221BS through MMBZ5259BS series of surface mount Zener diodes. The series offers various voltage options packaged in the SOT-363 format. The MMBZ5237BS variant specifically targets the 8.2V breakdown voltage requirement within this lineup.
Replacement Considerations
Direct substitutes include other MMBZ5237BS variants from Diodes Incorporated with compatible packaging. Verify pinout compatibility and electrical parameters such as Zener voltage tolerance and impedance when considering alternative manufacturers or packages.
