Equivalent & Substitute Parts for UDZS22B

Part Overview

The UDZS22B is a Zener diode produced by Taiwan Semiconductor Corporation, categorized under Diodes, Zener. It features a nominal Zener voltage of 22 V, maximum power dissipation of 200 mW, and a tolerance of ±2%. The device is housed in an SOD-323F surface-mount package and is rated for operating temperatures from -55°C to 150°C. The part's active status ensures ongoing availability, but alternative models may be required for purposes such as sourcing from different distribution channels, packaging format needs, or inventory management.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the UDZS22B Zener diode is determined by a strict match of key electrical and mechanical parameters. Equivalent and substitute parts must have identical Zener voltage (22 V), tolerance (±2%), maximum power rating (200 mW), maximum impedance (80 Ohms), reverse leakage current at specified voltage (45 nA @ 17 V), operating temperature (-55°C ~ 150°C), mounting style (Surface Mount), and the same package (SOD-323F). Regulatory compliance (RoHS3, REACH, ECCN) and part status (Active) must also be identical to allow direct substitution.

Parameter Comparison

Engineering Selection Recommendations

Both UDZS22B and UDZS22B R9G are active, ROHS3 compliant, and REACH unaffected. They possess identical electrical, mechanical, and compliance characteristics. Both are suitable for direct substitution strictly based on the provided parameters and regulatory certifications.

Frequently Asked Questions (FAQ)

Q: What are the critical parameters for substituting UDZS22B in a design?
A: Parameters include Zener voltage (22 V), tolerance (±2%), maximum power (200 mW), impedance (80 Ohms), reverse leakage (45 nA @ 17 V), operating temperature (-55°C ~ 150°C), mounting type (Surface Mount), and package (SOD-323F).

Q: Are there any mechanical differences between UDZS22B and UDZS22B R9G?
A: Both are supplied in the SOD-323F (SC-90) surface-mount package.

Q: Does the packaging format affect component substitution?
