ZDT6718TC

Overview

The ZDT6718TC is a dual zener diode array manufactured by Diodes Incorporated, housed in an SOT-23-3 surface-mount package. It features a common cathode configuration with two independent zener junctions. The nominal zener voltage is 6.8 V with a tolerance of ±5%. The device supports a maximum power dissipation of 300 mW and exhibits a maximum zener impedance of 40 Ohms at a test current of 5 mA. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Dual zener diode array with common cathode configuration for space-efficient circuit design
• High thermal stability supporting operation up to 150°C junction temperature
• Compact SOT-23-3 surface-mount package suitable for automated assembly

Applications

• Voltage reference circuits requiring dual stable voltage levels
• Transient voltage suppression in low-power signal lines
• Clamping applications in portable electronic devices

Procurement Notes

Verify the specific suffix (TC) against the manufacturer's latest datasheet to confirm tape and reel specifications. Ensure compatibility with standard SOT-23-3 footprint designs. Confirm RoHS compliance status for your region. Check for any recent lifecycle notices regarding this specific part number before finalizing procurement plans.

Selection Notes

Select this component when a dual zener solution is required in a minimal footprint. The 6.8 V rating suits general-purpose logic level protection. Consider the 300 mW power limit for thermal management. The SOT-23-3 package offers high-density mounting options compared to larger through-hole alternatives.

Part Context

This part belongs to Diodes Incorporated's discrete semiconductor portfolio, specifically within the zener diode array category. It complements single-channel zener offerings by providing dual functionality in a three-terminal package. The series targets cost-sensitive consumer electronics and industrial control applications requiring reliable voltage regulation.

Replacement Considerations

Consult official substitution guides for pin-compatible alternatives. Verify that replacement parts match the 6.8 V nominal voltage and 300 mW power dissipation ratings. Ensure the alternative maintains the SOT-23-3 package outline for direct board replacement without layout modifications.
