BZX84C4V7

Overview

The BZX84C4V7 is a Zener diode manufactured by Shenzhen Slkormicro Semicon Co., Ltd. It features a nominal Zener voltage of 4.7 V with a tolerance range of 4.4 V to 5.0 V at a test current of 5 mA. The device has a maximum power dissipation of 250 mW and operates within a junction temperature range up to 150°C. It is housed in an SOT-23 surface-mount package, suitable for compact circuit designs.

Feature Summary

• Provides stable voltage regulation within specified limits
• Automotive grade qualification under AEC-Q101 standards
• Compact surface-mount packaging for space-constrained applications

Applications

• Voltage reference circuits
• General-purpose voltage regulation
• Over-voltage protection

Procurement Notes

Verify the specific manufacturer designation as the BZX84C4V7 part number may be associated with other producers like Nexperia. Confirm RoHS compliance and AEC-Q101 automotive qualification status directly with the supplier documentation before procurement to ensure alignment with project requirements.

Selection Notes

Select this component when a 4.7 V reference is required in an SOT-23 package. Ensure the application current does not exceed the 5 mA test condition significantly to maintain voltage accuracy. Verify thermal management capabilities given the 250 mW power dissipation limit in enclosed spaces.

Part Context

This component belongs to the standard Zener diode family designed for general electronic applications. It serves as a fundamental passive semiconductor device for maintaining steady voltage levels in low-power circuits, distinct from active switching or amplification components.

Replacement Considerations

The BZX84C4V7LY is documented as a parameter-equivalent alternative with the same pinout and package. Verify electrical specifications match exactly before substitution.
