BZX84C4V7LT116 Equivalent & Substitute Parts Reference

Part Overview

The Rohm Semiconductor BZX84C4V7LT116 is a surface mount Zener diode designed for voltage regulation applications, featuring a nominal Zener voltage of 4.7 V, a maximum power dissipation of 250 mW, and a ±6.38% tolerance. The diode is supplied in a TO-236-3, SC-59, SOT-23-3 (SSD3) package. It is currently active and compliant with ROHS3 and REACH, with a Moisture Sensitivity Level (MSL) of 1 (unlimited). Sourcing alternative models of SMD Zener diodes is essential for supply chain resilience, price optimization, and consistent production where packaging, electrical, and compliance parameters must be strictly equivalent.

Engineering Selection Recommendations

BZX84C4V7LT116 and its listed substitutes are all active, RoHS3 compliant, and REACH unaffected. All substitute parts share a surface mount configuration and compatible package forms, with MSL 1 (unlimited) moisture sensitivity. Certification for automotive qualification (AEC-Q101) is noted on automotive-grade variants. Differences in tolerance and supplier device package must be considered based on application requirements as provided in the comparison table.

Frequently Asked Questions (FAQ)

Q1: What parameters are critical when substituting BZX84C4V7LT116 in a circuit?
A1: Critical parameters include voltage - Zener (nom), tolerance, maximum power dissipation, maximum impedance, maximum reverse leakage current, package type, mounting method, RoHS status, REACH status, and MSL.

Q2: Are all packages listed fully compatible?
A2: All substitute parts use TO-236-3, SC-59, or SOT-23-3 package outlines. Supplier device package identifiers such as SSD3, SOT-23, and TO-236AB represent variations specific to each manufacturer, but all conform to the same mounting standards as listed.

Q3: Is automotive qualification (AEC-Q101) consistent across all substitute parts?
A3: Only designated automotive-grade parts indicate qualification to AEC-Q101. Refer to the "Qualification" field in the detailed part descriptions.

Q4: Do all parametric equivalents comply with RoHS and REACH requirements?
A4: All parts listed are RoHS3 compliant and REACH unaffected.

Q5: Can lower tolerance substitute parts be used directly?
A5: Substitute parts with tighter tolerance values are included based on provided parameters. All tolerances must be considered only as specified in the table.
