S1GLHM2G Equivalent & Substitute Parts Reference

Part Overview

The S1GLHM2G, manufactured by Taiwan Semiconductor Corporation, is a surface-mount rectifier diode categorized under Diodes, Rectifiers, with a maximum repetitive reverse voltage of 400 V and a continuous forward current of 1 A. This part is designed for general-purpose rectification, offering standard recovery and automotive-grade reliability with AEC-Q101 qualification. The component is active and available in the DO-219AB (Sub SMA) package. Identification of equivalent or substitute models is relevant for cases involving supply continuity, inventory alignment, or design standardization.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are determined strictly by matching electrical and mechanical parameters relevant to the S1GLHM2G's function and footprint requirements. Key criteria for equivalence are:

• Maximum repetitive reverse voltage (Vr)
• Continuous forward current (Io)
• Maximum forward voltage (Vf) at rated current
• Reverse recovery time (trr)
• Reverse leakage current at rated voltage
• Capacitance at specified voltage and frequency
• Package type (DO-219AB; Sub SMA)
• Mounting type (Surface Mount)
• Operating temperature range
• Compliance with RoHS3, AEC-Q101, and REACH standards

Only parts matching these criteria are considered parametric equivalents.

Parameter Comparison

Engineering Selection Recommendations

Based strictly on product status and environmental compliance, the S1GLHM2G is active and qualified for automotive applications with AEC-Q101 certification, RoHS3 compliance, and an unlimited MSL rating. The S1GL is marked as "Not For New Designs" but matches all listed electrical and mechanical parameters. For designs requiring only active-status components or automotive qualification, S1GLHM2G is suitable. For legacy or inventory-driven requirements where "Not For New Designs" status is acceptable, S1GL can serve as a parametric equivalent.

Frequently Asked Questions (FAQ)

Q1: What parameters are required for a substitute diode to match S1GLHM2G?
A1: Substitute parts must have identical ratings for reverse voltage (400 V), continuous forward current (1A), forward voltage drop (1.1 V @ 1A), reverse recovery time (1.8 µs), reverse leakage current (5 µA @ 400 V), capacitance (9pF @ 4V, 1MHz), package (DO-219AB; Sub SMA), surface-mount compatibility, and operating temperature range (-55°C ~ 175°C).

Q2: Is S1GL a direct substitute for S1GLHM2G?
A2: S1GL matches all critical electrical and mechanical parameters as per the provided data. Product status is "Not For New Designs," which may impact selection depending on the application.

Q3: Are there differences in compliance or status between S1GLHM2G and S1GL?
A3: Both are RoHS3 compliant and REACH unaffected. S1GLHM2G holds an active status, while S1GL is listed as "Not For New Designs."

Q4: Does the package type affect substitutability?
A4: Yes. Both S1GLHM2G and S1GL are in DO-219AB (Sub SMA) packages and are surface-mount, meeting footprint and assembly compatibility requirements.

Q5: Are there considerations about automotive qualification?
A5: S1GLHM2G is automotive-grade with AEC-Q101 qualification, aligning with requirements for automotive or robust industrial applications. S1GL’s qualification status is not explicitly indicated beyond compliance data provided.
