1. Operating Temperature Range: The AZ23C30-7-F supports -65°C to 150°C, while the 2BZX84C30 is rated for -50°C to 150°C. The former is suitable for harsher low-temperature environments (such as certain industrial, automotive, or aerospace applications), whereas the latter may fall out of specification below -50°C. 2. Manufacturer and Data Integrity: Diodes Incorporated generally provides more comprehensive public data and model support. In contrast, Diotec’s datasheet explicitly specifies reverse leakage current (50nA @ 21V), reflecting deeper control over certain parameters. For leakage-sensitive designs, Diotec’s explicit data may offer greater reference value. 3. Supply Chain and Quality System Variations: Although electrical parameters are essentially identical, differences may exist in supply chain sources, quality control standards, and long-term supply stability due to different manufacturers. For critical applications, assessment should include supplier audits and historical reliability data.
