BZT52C22T-7

Single Zener Diodes Overview

The BZT52C22T-7 is a surface-mount Zener diode manufactured by Diodes Incorporated, housed in an SOD523 package. It features a nominal Zener voltage of 22 V with a tolerance range of 20.8 V to 23.3 V at a test current of 5 mA. The device has a maximum power dissipation of 300 mW and a maximum Zener impedance of 55 Ω at the test current. Maximum reverse leakage current is specified as 0.1 µA at 15.4 V. The component operates within a temperature range of -55°C to +150°C.

Single Zener Diodes Feature Summary

• Small, low-profile surface-mount package designed for automated assembly processes
• Totally lead-free and fully RoHS compliant construction
• Halogen and antimony free "Green" device
• Qualified to JEDEC standards for high reliability

Single Zener Diodes Applications

• Voltage regulation circuits
• Overvoltage protection applications
• Reference voltage generation

Single Zener Diodes Procurement Notes

Verify the specific ordering suffix matches the required packing quantity, as the -7 suffix indicates a 3,000-unit tape and reel carrier. Confirm that the standard commercial grade meets application requirements, noting that automotive-specific change control requires parts with the Q-suffix. Ensure compatibility with moisture sensitivity level 1 per J-STD-020 during storage and handling.

Single Zener Diodes Selection Notes

Select this component when a compact SOD523 footprint is required for 22 V regulation. Verify that the 300 mW power dissipation rating suits the thermal environment, considering the junction-to-ambient thermal resistance. Check if the standard commercial qualification is sufficient or if AEC-Q100/101 qualified variants are necessary for the target market.

Single Zener Diodes Part Context

This part belongs to the BZT52C2V0T through BZT52C36T series of surface-mount Zener diodes from Diodes Incorporated. The series utilizes planar die construction and offers various voltage options within the SOD523 package. The product line is designed for general-purpose electronic applications requiring reliable voltage clamping in small form factors.

Single Zener Diodes Replacement Considerations

Direct substitutes include other BZT52C22T variants from Diodes Incorporated with different packaging suffixes, such as BZT52C22T-13 for 10,000-unit reels. Cross-manufacturer replacements must match the SOD523 package dimensions, 22 V nominal voltage, and 300 mW power rating.
