BZX84C9V1S-7-F

Overview

The BZX84C9V1S-7-F is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features planar die construction within an SOT-363 package, providing two independent voltage regulation channels in a compact form factor. The nominal Zener voltage is 9.1 V with a standard tolerance of ±5%, ranging from 8.5 V to 9.6 V. Maximum power dissipation is 200 mW at 25°C ambient temperature. Electrical characteristics include a maximum Zener impedance (ZZT) of 15 Ω and a maximum reverse leakage current (IR) of 0.5 µA at 6.0 V. The device operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Dual configuration offering two independent Zener diodes in a single ultra-small SOT-363 surface mount package.
• Planar die construction designed for high reliability and consistent performance in space-constrained circuit designs.
• Lead-free and RoHS compliant manufacturing process utilizing matte tin finish plating over an Alloy 42 leadframe.

Applications

• General voltage regulation functions in low-power electronic circuits.
• Voltage reference applications requiring stable DC levels.
• Over-voltage protection for sensitive input lines.

Procurement Notes

Verify the specific ordering suffix '-7-F' corresponds to the 3000-unit tape and reel packaging format required for automated assembly processes. Confirm that the SOT-363 footprint matches the PCB pad layout specifications provided in the manufacturer's application notes to ensure proper soldering and mechanical stability during reflow.

Selection Notes

Select this component when a dual-channel voltage regulation solution is needed within strict volume constraints. The 200 mW power rating limits suitability to low-current applications; higher power requirements necessitate alternative packages such as SOD-323 or DO-35. Ensure the 9.1 V nominal voltage aligns with the target circuit reference requirements and that the ±5% tolerance meets the design margin specifications.

Part Context

This part belongs to the BZX84C series of dual Zener diodes produced by Diodes Incorporated. The series utilizes the SOT-363 package to provide multiple regulation options in minimal board space. The 'C' designation indicates a standard 5% voltage tolerance, distinguishing it from tighter tolerance variants. The suffix '-7-F' specifically denotes the reel packaging configuration used for high-volume surface mount production.

Replacement Considerations

Direct pin-compatible replacements within the same series include BZX84C8V2S-7-F and BZX84C10S-7-F, which share identical packaging and electrical configurations but differ in nominal Zener voltage. Verify that any substitute maintains the required 200 mW power dissipation and SOT-363 footprint compatibility.
