BZX84C3V3TS-7-F

Overview

The BZX84C3V3TS-7-F is a triple surface mount Zener diode array manufactured by Diodes Incorporated. It integrates three isolated diode elements within a single SOT-363 package, designed for high-density applications. The nominal Zener voltage is 3.3 V, with a tolerance range of 3.1 V to 3.5 V at a test current (IZT) of 5 mA. Maximum power dissipation is 200 mW, and the thermal resistance from junction to ambient air is 625 °C/W. The device operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum Zener impedance (ZZT) of 95 Ω at IZT and a maximum reverse leakage current (IR) of 5 µA at VR = 1.0 V.

Feature Summary

• Integrates three independent Zener diode elements in a compact ultra-small surface mount package
• Constructed using planar die technology for reliable performance
• Compliant with RoHS standards and lead-free plating specifications

Applications

• Voltage regulation circuits requiring multiple reference points
• High-density board assembly designs
• Portable electronic devices due to small footprint

Procurement Notes

Verify the specific ordering suffix matches the required packaging configuration. Confirm that the component meets environmental compliance requirements such as RoHS and lead-free status if mandated by the design specifications. Ensure the date code aligns with manufacturing material policies regarding halogen content or green molding compounds.

Selection Notes

Select this component when a circuit requires three distinct Zener references within a limited PCB area. The SOT-363 package offers a solution for space-constrained designs compared to discrete individual diodes. Verify that the 200 mW power dissipation rating is sufficient for the intended operating conditions and thermal environment.

Part Context

This part belongs to the BZX84C...TS series of triple surface mount Zener diode arrays. The series covers a wide range of Zener voltages from 2.4 V to 39 V, all sharing the same SOT-363 package outline and mechanical data. The 'TS' designation indicates the triple configuration, while '-7-F' specifies the tape and reel packaging quantity.

Replacement Considerations

Direct substitutes within the same family include other BZX84CxxTS-7-F variants with different Zener voltages but identical pinouts and packages. Cross-manufacturer equivalents must be verified against the SOT-363 dimensions and electrical parameters to ensure compatibility.
