BAS40HMFHT116 Equivalent & Substitute Parts Reference Page

Part Overview

The Rohm Semiconductor BAS40HMFHT116 is an automotive-grade Schottky diode in the Diodes, Rectifiers category. Key features include a 40 V reverse voltage, 120mA average rectified current, surface-mount SSD3 package, and compliance with ROHS3 and AEC-Q101 standards. The product status is active, ensuring ongoing availability, but engineering design and supply chain flexibility may require identifying alternative or equivalent models. Substitution is necessary for BOM multi-sourcing, supply continuity, and cross-manufacturer compatibility.

Engineering Selection Recommendations

All listed substitute parts have active product status, automotive grade, and meet RoHS3 and REACH compliance requirements. Qualification levels (AEC-Q101 or AEC-Q100) are provided, ensuring certified reliability for automotive applications. Moisture Sensitivity Level 1 (Unlimited) is identical across all substitutes, supporting manufacturing flexibility without handling restrictions. Substitute selections are valid for applications requiring the documented parameters and certifications.

Frequently Asked Questions (FAQ)

Q1: What are the main criteria for an equivalent or substitute BAS40HMFHT116 diode?
A1: Substitution requires Schottky technology, 40 V reverse voltage, ≥120mA rectified current, matching forward voltage and reverse leakage, automotive qualification, surface-mount package compatibility (TO-236-3, SC-59, SOT-23-3), identical operating temperature, RoHS, REACH, and MSL compliance.

Q2: Are substitute diodes from different manufacturers directly compatible in placement and performance?
A2: Substitute parts listed share surface-mount type and package standards. Electrical characteristics and qualification standards are as specified for cross-manufacturer compatibility.

Q3: Does the substitute list include only automotive-qualified parts?
A3: All substitutes are either AEC-Q101 or AEC-Q100 qualified and marked as automotive grade as provided in the input.

Q4: Is it necessary to match the package and supplier device package for all substitutes?
A4: Yes. Only parts with identical or overlapping package/case parameters (TO-236-3, SC-59, SOT-23-3) are included for direct substitution.

Q5: How does compliance status affect engineering selection?
A5: All substitutes are ROHS3 compliant, REACH unaffected, and have a moisture sensitivity level of 1 (Unlimited), supporting standard manufacturing and environmental requirements.
