Equivalent & Substitute Parts for UDZS30B Zener Diode

Part Overview

The UDZS30B is a Zener diode manufactured by Taiwan Semiconductor Corporation in the Diodes, Zener category. It is supplied in the SOD-323F package, with a rated power dissipation of 200 mW, nominal Zener voltage of 30 V, and a tolerance of ±2%. The device is surface-mountable and is designed for small signal regulation and protection applications. The part status is Active and is available in Tape & Reel (TR) packaging. When sourcing Zener diodes for designs requiring precise voltage regulation, it is often necessary to identify parametric equivalents or substitutes, especially for maintaining inventory levels or meeting compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are selected strictly based on matching electrical and mechanical parameters provided for the UDZS30B. These include nominal Zener voltage (30 V), tolerance (±2%), maximum power dissipation (200 mW), maximum impedance at test current (100 Ohms), reverse leakage current at specified voltage (45 nA @ 23 V), operating temperature range (-55°C ~ 150°C), mounting type (surface mount), package/case (SC-90, SOD-323F), supplier device package (SOD-323F), RoHS status, and REACH status. All substitutions are limited to parts meeting these exact criteria.

Parameter Comparison

Engineering Selection Recommendations

Both UDZS30B and UDZS30B RRG maintain Active status, are ROHS3 Compliant, and have unaffected REACH status. Selection between these two part numbers can be made based on current inventory levels, with no additional compliance requirements introduced.

Frequently Asked Questions (FAQ)

Q: What parameters must be matched to consider UDZS30B RRG as a substitute for UDZS30B?
A: The substitute must have identical Zener voltage, tolerance, maximum power rating, maximum impedance, reverse leakage current, operating temperature range, mounting type, and package dimensions as listed.

Q: Is the SOD-323F package critical for substitution in Zener diode applications?
A: Yes, matching the SOD-323F package ensures compatibility with existing surface mount footprints and automated assembly processes.

Q: Are there differences in compliance or environmental certifications between UDZS30B and UDZS30B RRG?
A: Both parts meet ROHS3 compliance and have REACH unaffected status.

Q: Does the part status affect substitution suitability?
A: Only active parts listed with compatible parameters are suitable substitutes for the UDZS30B.

Q: Can both parts be used in the same temperature environments and with the same test procedures?
A: Yes, both share identical operating temperature ranges and electrical performance characteristics.
