2BZX84C13

Overview

The Diotec Semiconductor 2BZX84C13 is a common anode SMD planar Zener diode housed in a SOT-23 (TO-236) package. It provides a nominal Zener voltage range of 12.4 V to 14.1 V at a test current of 5 mA, with a dynamic resistance of less than 30 Ohms. The device supports a total power dissipation of 300 mW and operates within a junction temperature range of -50°C to +150°C. Standard tolerance follows the E24 series at ±5%. Reverse leakage current is specified at 0.1 µA when tested at 8 V.

Feature Summary

• Common Anode configuration for dual-diode applications
• Sharp Zener voltage breakdown characteristics
• Low reverse leakage current performance

Applications

• Voltage stabilization circuits
• Voltage regulator designs

Procurement Notes

Verify the specific suffix against official documentation to confirm grade. The standard commercial version lacks automotive qualification. Confirm RoHS compliance status and REACH requirements prior to integration. Ensure the ordering code matches the required tolerance and packaging specifications.

Selection Notes

Select this component for low-power surface-mount regulation tasks requiring a shared reference node. Verify that the 300 mW thermal rating accommodates the expected operating conditions on the PCB. Check if the common anode topology fits the circuit design better than single diodes.

Part Context

This part belongs to the BZX84Cxx and 2BZX84Cxx family of SMD Planar Zener Diodes from Diotec Semiconductor. The '2' prefix indicates the common anode variant, while the numeric suffix denotes the specific Zener voltage rating within the 2.4 V to 47 V range.

Replacement Considerations

Single diode equivalents such as BZX84C13 can replace this part if two separate components are acceptable. Automotive-grade alternatives include the BZX84C13-AQ or BZX84C13/-AQ variants for enhanced reliability standards.
