MMDL101T1 Schottky Diode Equivalent & Substitute Parts

Part Overview

The MMDL101T1 is an RF Schottky diode manufactured by onsemi, rated for 7V peak reverse voltage with 200 mW power dissipation in SOD-323 packaging. This component is classified as obsolete, making equivalent substitutes necessary for new designs and production continuity. The part operates across a wide temperature range of -55°C to 150°C (TJ) and is suitable for RF and switching applications requiring low forward voltage characteristics typical of Schottky technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the MMDL101T1 is determined by the following critical parameters:

Direct Substitutes must maintain:

• Schottky diode technology (single junction)
• Voltage rating of 7V or higher
• Power dissipation capability of 200 mW or greater
• SOD-323 package compatibility
• Capacitance characteristics suitable for RF applications

Similar Substitutes may accommodate:

• Higher voltage ratings (10V) with equivalent or superior current handling
• Enhanced thermal performance
• Improved compliance status (RoHS3, AEC-Q100 qualification)
• Alternative SOD-323 variants (SOD-323F)

The MMDL101T1G qualifies as a direct substitute due to identical electrical specifications and packaging. The PMEG1030EJ,115 functions as a similar substitute with enhanced specifications suitable for higher-performance applications.

Parameter Comparison

Engineering Selection Recommendations

MMDL101T1G is the primary substitute for direct replacement. It maintains identical electrical specifications and packaging while offering active product status and ROHS3 compliance. This part is suitable for applications requiring exact electrical equivalence with improved regulatory compliance.

PMEG1030EJ,115 serves as an alternative for applications tolerating higher voltage ratings (10V vs 7V) and increased current capacity (3A average rectified current). The higher capacitance (85pF vs 1pF) indicates different RF characteristics and should be evaluated for frequency-dependent applications. This part includes AEC-Q100 automotive qualification and is recommended for designs requiring enhanced reliability specifications or automotive-grade components.

Selection between MMDL101T1G and PMEG1030EJ,115 depends on circuit requirements: choose MMDL101T1G for parameter-matched replacement; choose PMEG1030EJ,115 for applications benefiting from higher voltage and current ratings with automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can MMDL101T1G be used as a direct replacement for MMDL101T1?

A: Yes. MMDL101T1G is electrically and mechanically equivalent, with identical voltage rating (7V), power dissipation (200 mW), capacitance (1pF @ 0V, 1MHz), and SOD-323 packaging. The primary difference is active product status and ROHS3 compliance.

Q: What are the key differences between MMDL101T1G and PMEG1030EJ,115?

A: MMDL101T1G maintains the original 7V specification, while PMEG1030EJ,115 provides 10V rating with 3A current capacity. Capacitance differs significantly (1pF vs 85pF @ 1MHz), affecting RF performance. PMEG1030EJ,115 uses SOD-323F packaging and includes AEC-Q100 automotive qualification.

Q: Is PMEG1030EJ,115 suitable for RF applications requiring low capacitance?

A: No. The PMEG1030EJ,115 capacitance of 85pF @ 1V, 1MHz is substantially higher than the MMDL101T1 specification of 1pF @ 0V, 1MHz. This part is designed for higher-current rectification rather than RF switching applications. Use MMDL101T1G for RF applications requiring low capacitance.

Q: Are there packaging compatibility concerns when substituting these parts?

A: MMDL101T1G uses identical SOD-323 packaging. PMEG1030EJ,115 uses SOD-323F, a variant of the same family with compatible footprints for most applications, though PCB layout should be verified for specific designs.

Q: What is the compliance status difference between these parts?

A: MMDL101T1 is RoHS non-compliant. Both MMDL101T1G and PMEG1030EJ,115 are ROHS3 compliant. All three parts are REACH unaffected and classified as EAR99 for export control purposes.
