Frequently Asked Questions (FAQ)

Q1: What are the key parameters when selecting a Zener diode substitute for BZX84C20VLFHT116?
A1: The key parameters are Zener voltage (20 V), power dissipation (250 mW), tolerance (±2% or ±6%), impedance at specified current (55 Ohms maximum), reverse leakage current (100 nA @ 14 V), operating temperature (150°C), mounting type (Surface Mount), package (TO-236-3, SC-59, SOT-23-3 or SOT-23), grade (Automotive where required), and qualification (AEC-Q101 where required).

Q2: Are TO-236-3, SC-59, SOT-23-3, and SOT-23 package types interchangeable in this context?
A2: Only the Zener diodes listed with these packages are valid substitutes, as all share compatible mechanical outlines under the stated part numbers.

Q3: Is it necessary to match the tolerance specification exactly when substituting?
A3: The provided data allows for substitution between ±2% and ±6% tolerance options. Both are accepted within these groups.

Q4: What compliance and moisture sensitivity factors should be considered?
A4: All substitutes have an MSL of 1 (Unlimited), ROHS3 compliance, and REACH unaffected status, matching the main part.

Q5: Are all alternates listed suitable for automotive-grade and AEC-Q101 qualified applications?
A5: Only alternates explicitly listed as Automotive grade and AEC-Q101 qualified in the input match those requirements.
