BZX84C33S-7

Overview

The BZX84C33S-7 is a dual surface mount Zener diode manufactured by Diodes Incorporated. It features planar die construction within an SOT-363 package, providing two independent Zener diodes in a single component. The nominal Zener voltage is 33V with a tolerance range of 31.0V to 35.0V at a test current (IZT) of 2.0mA. Maximum reverse leakage current is 0.1µA at VR = 23.1V. Total power dissipation is rated at 200mW, and the device operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual configuration containing two independent Zener diodes in one compact package
• Planar die construction for stable electrical performance
• Lead-free plating with matte tin finish over Alloy 42 leadframe

Applications

• General voltage regulation functions
• Clamping applications requiring dual channels
• Voltage reference circuits

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. Confirm that the component meets required environmental standards such as RoHS compliance and moisture sensitivity levels before integration into production schedules.

Selection Notes

Select this component when space constraints require dual Zener functionality in a small footprint. Ensure the circuit design accommodates the 200mW total power dissipation limit and verify that the 33V breakdown voltage aligns with the target reference or clamping requirements.

Part Context

This part belongs to the BZX84C2V4S through BZX84C39S series of dual Zener diodes. The series utilizes the SOT-363 case style and offers various normalized breakdown voltages ranging from 2.4V to 39V with approximately ±5% tolerance.

Replacement Considerations

Direct substitutes include other dual Zener arrays in SOT-363 packages with matching 33V ratings. Verify pinout compatibility and thermal resistance characteristics when evaluating alternative manufacturers.
