Overview
The MMBZ5243BS-7-F is a dual isolated Zener diode manufactured by Diodes Incorporated, housed 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 supports a maximum power dissipation of 200 mW and operates within a temperature range of -65°C to +150°C. Electrical specifications include a maximum Zener impedance of 13 Ohms and a maximum reverse leakage current of 600 nA at 9.9 V.
Feature Summary
- Dual isolated Zener configuration within an ultra-small surface mount package
- Planar die construction designed for automated assembly processes
- Lead-free and RoHS compliant manufacturing
Applications
- Voltage regulation circuits requiring compact dual-channel solutions
- General-purpose medium current applications
- Automated surface-mount assembly lines
Procurement Notes
Verify the complete part number includes the suffix -7-F to confirm tape and reel packaging containing 3000 units per reel. Confirm the specific marking code KH3 matches the required 13 V specification during component inspection. Ensure compliance with UL 94V-0 flammability ratings if required by the final equipment design standards.
Selection Notes
Select this component when space constraints necessitate a dual-diode solution in an SOT-363 footprint. Compare against single-diode alternatives like MMBZ5243B if only one channel is needed. Verify that the 200 mW power dissipation rating aligns with the thermal management capabilities of the target PCB layout under expected operating conditions.
Part Context
This component belongs to the MMBZ5221BS through MMBZ5259BS series from Diodes Incorporated. The series provides various Zener voltage options ranging from 2.4 V to 39 V in a standardized dual-isolated surface-mount format. The MMBZ5243BS specifically addresses the 13 V requirement within this product family lineup.
