Overview
The BZX84C27S-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated, housed in an SOT-363 package. It provides two independent Zener diodes with a nominal voltage of 27V and a tolerance range of 25.1V to 28.9V at a test current of 2mA. The device features 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 80 Ohms at 2mA and a reverse leakage current of 0.1µA at 18.9V. The forward voltage is specified as 0.9V at 10mA.
Feature Summary
- Dual configuration containing two independent Zener diodes within a single ultra-small surface mount package.
- Planar die construction designed for general-purpose regulation functions and automated assembly processes.
- RoHS compliant and lead-free manufacturing process utilizing matte tin finish plating.
Applications
- General voltage regulation circuits requiring dual reference voltages.
- Clamping applications for signal protection in compact electronic devices.
- Biasing networks in low-power analog circuitry.
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 KYA matches the required 27V specification on the component body. Ensure compatibility with standard SOT-363 footprint layouts during PCB design validation.
Selection Notes
Select this component when a dual Zener configuration is required in space-constrained designs. The SOT-363 package offers a smaller footprint compared to discrete single diodes. Consider the 200mW total power dissipation limit and thermal resistance of 625°C/W for heat management in enclosed environments.
Part Context
This component belongs to the BZX84C2V4S through BZX84C39S series of dual Zener diodes from Diodes Incorporated. The series utilizes normalized E24 voltage values ranging from 2.4V to 39V. All variants share identical mechanical dimensions and electrical testing conditions, differing primarily in breakdown voltage specifications and corresponding marking codes.
Replacement Considerations
Direct substitutes within the same series include BZX84C24S-7-F and BZX84C30S-7-F, which maintain identical package and pinout configurations. Cross-manufacturer replacements must verify matching SOT-363 dimensions and equivalent 200mW power ratings.
