BZT585B2V4TQ-13

Single Zener Diodes Overview

The BZT585B2V4TQ-13 is a surface mount precision Zener diode manufactured by Diodes Incorporated. It features a nominal breakdown voltage of 2.4 V with a tight tolerance range of 2.35 V to 2.45 V at a test current of 5 mA. The device operates within a continuous forward current of 200 mA and dissipates up to 350 mW of power. It is housed in an SOD523 package, measuring approximately 1.25 mm in length, 0.85 mm in width, and 0.65 mm in height. Electrical characteristics include a maximum Zener impedance of 100 Ohms at 5 mA, a temperature coefficient of -1.3 mV/°C, and a maximum reverse leakage current of 50 µA at 1 V.

Single Zener Diodes Procurement Notes

Verify the complete part number including the suffix '-13' to confirm the 10,000 unit tape and reel packing quantity. Ensure the component meets RoHS 2 and RoHS 3 directives if environmental compliance is required. Confirm that the application environment stays within the specified operating temperature range of -65°C to +150°C. Check for any specific marking code requirements corresponding to the '3C' product type marking.

Single Zener Diodes Selection Notes

Select this component when a precise 2.4 V reference is needed in a compact SMD footprint. The tight 2% tolerance makes it suitable for sensitive analog circuits. Consider the negative temperature coefficient of -1.3 mV/°C when designing for wide thermal variations. The 350 mW power dissipation rating supports moderate current loads in the SOD523 package.

Single Zener Diodes Part Context

This device belongs to the BZT585B series of surface mount precision Zener diodes from Diodes Incorporated. The series covers a voltage range from 2.4 V to 43 V, all sharing the same SOD523 package and ±2% tolerance specification. The BZT585B2V4TQ-13 specifically denotes the 2.4 V variant packaged in reels of 10,000 units.

Single Zener Diodes Replacement Considerations

Other variants within the BZT585B series (e.g., BZT585B2V7TQ) offer different voltages but share identical packaging and tolerance specifications. Cross-referencing with other manufacturers requires verifying matching voltage tolerance, package dimensions, and AEC-Q101 qualification status.
