BZX84C2V7TS-7-F

Overview

The BZX84C2V7TS-7-F is a triple surface mount Zener diode array from Diodes Incorporated, housed in an SOT-363 package. It contains three isolated diode elements within a single ultra-small case. The specific device provides a nominal Zener voltage of 2.7V with a tolerance range of 2.5V to 2.9V at a test current (IZT) of 5mA. Maximum Zener impedance is 100Ω at IZT and 600Ω at IZK (600mA). Maximum reverse current is 1.0µA at 20V. Power dissipation is 200mW, with a thermal resistance of 625°C/W. Operating temperature ranges from -65°C to +150°C.

Feature Summary

• Integrates three electrically isolated Zener diode channels into one compact SOT-363 surface mount package for space-constrained designs.
• Compliant with RoHS standards and manufactured using lead-free plating with a matte tin finish over an Alloy 42 leadframe.
• Features molded plastic case material with UL flammability classification rating of 94V-0.

Applications

• Voltage reference circuits requiring multiple independent reference levels on a single footprint.
• Transient voltage suppression in low-voltage signal lines.
• Clamping applications for protecting sensitive input pins in portable electronic devices.

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 marking code KRC corresponds to the 2.7V variant. Ensure the source document matches Diodes Incorporated datasheet DS30187 Rev. 11 or later to validate electrical characteristics and mechanical dimensions.

Selection Notes

Select this component when three isolated Zener references are needed in minimal board area. The 2.7V nominal voltage suits low-voltage logic protection. Verify that the 100Ω maximum impedance at 5mA meets circuit requirements. Check thermal constraints, as the SOT-363 package has high thermal resistance (625°C/W), limiting power dissipation to 200mW under standard conditions.

Part Context

This part belongs to the BZX84C series of triple Zener arrays offered by Diodes Incorporated. The series spans Zener voltages from 2.4V to 39V, sharing the same SOT-363 mechanical outline and pin configuration. Variants differ primarily in Zener voltage, impedance, and reverse current specifications while maintaining identical package and thermal characteristics.

Replacement Considerations

Direct substitutes include other BZX84C2V7TS variants from different manufacturers if pin-compatible. Cross-reference with BZX84C2V7T-7 or similar triple Zener arrays in SOT-363 packages. Verify that replacement parts match the 2.5V-2.9V voltage tolerance and 100Ω impedance limits specified in the original datasheet.
