PZM6.2NB2,115 Equivalent & Substitute Parts Engineering Reference

Part Overview

The NXP PZM6.2NB2,115 is a 6.2V zener diode in a surface-mount SMT3 (SOT-23-3) package, with a maximum power dissipation of 300mW and ±2% voltage tolerance. It is RoHS3 compliant, with an operating temperature range of -65°C to 150°C, maximum zener impedance of 10 Ohms, and forward voltage of 1.1V at 100mA. The part is marked obsolete, which makes the selection of equivalent or substitute models essential for ongoing engineering support and production continuity.

Substitute Part Grouping Explanation

Substitute and equivalent parts for PZM6.2NB2,115 are selected strictly based on the following key parameters: zener voltage (6.2V, ±2%), maximum power rating (≥225mW), maximum zener impedance (≤10 Ohms), reverse leakage current (≤3µA at voltage conditions), forward voltage, identical SOT-23-3/TO-236-3 form factor for compatibility, and operating temperature range (-65°C to 150°C). All listed substitutes provide RoHS3 compliance, meet the noted moisture sensitivity and have matching mounting and packaging standards.

Engineering Selection Recommendations

Select substitute or equivalent parts for PZM6.2NB2,115 that carry current "Active" inventory status, are ROHS3 Compliant, meet the specified operating temperature range, and use the SOT-23-3/TO-236-3 package. Follow project requirements for environmental compliance and supply continuity. Substitute selection must strictly contain the part numbers listed in the comparison table with aligned specifications and certifications.

Frequently Asked Questions (FAQ)

Q1: What are the essential parameters for replacing PZM6.2NB2,115?
Only voltage - zener (nominal) 6.2V, ±2% tolerance, equivalent or higher power rating, maximum zener impedance, leakage current within stated limits, surface-mount SOT-23-3/TO-236-3 packaging, and environmental compliance.

Q2: Are the pinouts and footprints for the listed substitutes identical?
All substitute part numbers are in compatible packages (TO-236-3, SC-59, SOT-23-3), matching mounting type and layout standards with PZM6.2NB2,115.

Q3: Do the listed substitute zener diodes comply with RoHS?
All specified equivalents are ROHS3 Compliant.

Q4: How does the obsolete status of PZM6.2NB2,115 affect engineering selection?
Parts with "Obsolete" status require substitutes with "Active" status and aligned electrical, mechanical, and compliance parameters for continued design support.

Q5: What are the permitted differences for power dissipation in substitutes?
Power rating must be equal to or greater than the minimum required by the circuit application, with listed substitutes ranging from 225 mW to 300 mW as specified.
