BZV55C39 Equivalent & Substitute Zener Diodes Reference

Part Overview

BZV55C39 is a surface mount Zener Diode, rated at 39 V nominal Zener voltage (±5%) in a DO-213AA (Glass) package by Microchip Technology. It is actively stocked and features low reverse leakage, standard forward voltage, and a broad operating temperature range from -65°C to 175°C. Identifying alternative part numbers is necessary due to considerations such as RoHS compliance requirements, inventory constraints, or specific packaging preferences. Substitution must adhere strictly to the provided electrical, mechanical, and regulatory characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute Zener diodes are grouped based on strict matching of these parameters: Zener voltage (39 V), tolerance (accepting up to ±5%), reverse leakage current rating, forward voltage, mounting type (surface mount), and package/case similarity (DO-213 or MINI-MELF variants). Regulatory and compliance statuses such as RoHS and MSL are taken directly from supplied details, aligning substitutes with permissible electrical, mechanical, and regulatory specifications.

Parameter Comparison

Engineering Selection Recommendations

Selection of an equivalent Zener diode must be based on product status, RoHS compliance, and moisture sensitivity level. The BZV55C39 (Microchip Technology) is active with RoHS non-compliant status. BZV55-B39,115 (Nexperia USA Inc.) provides ROHS3 compliance and an active status, matching the required electrical parameters. BZV55-C39,115 (NXP Semiconductors) also presents matching electrical characteristics with MSL 1 (Unlimited); RoHS status is not specified in the provided data. Product status for all parts is active.

Frequently Asked Questions (FAQ)

Q1: Which parameters are crucial for selecting a substitute Zener diode for BZV55C39?
A1: Zener voltage (39 V), tolerance (up to ±5%), reverse leakage current, forward voltage, mounting type (surface mount), and mechanical package form factor.

Q2: Are package differences between DO-213AA and DO-213AC, MINI-MELF, SOD-80 significant?
A2: The substitute parts listed use DO-213AC, MINI-MELF, SOD-80, which is a surface-mount form similar in electrical and mounting characteristics to DO-213AA.

Q3: What regulatory differences exist among the substitutes?
A3: BZV55C39 is RoHS non-compliant. BZV55-B39,115 is ROHS3 Compliant. BZV55-C39,115 does not have its RoHS compliance specified in the provided details.

Q4: How does Moisture Sensitivity Level (MSL) affect selection?
A4: All compared parts specify MSL 1 (Unlimited), indicating suitability for standard assembly and storage conditions.

Q5: Can lower tolerance substitutes be used for a ±5% part?
A5: A part with a tighter (lower) tolerance than required meets the substitution criteria, as shown in the provided comparison.
