SS115LHMHG Equivalent & Substitute Parts

Part Overview

The SS115LHMHG is a Schottky rectifier diode manufactured by Taiwan Semiconductor Corporation, designed for surface mount applications in the Sub SMA package format. This component operates at 150 V DC reverse voltage with 1 A average rectified current and features fast recovery characteristics suitable for automotive-grade applications. The part is currently in active product status with AEC-Q101 qualification.

Identification of equivalent and substitute parts becomes necessary when the primary part number reaches end-of-life status, experiences supply constraints, or when design flexibility is required across manufacturing revisions while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SS115LHMHG is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part SS115L maintains identical specifications for voltage rating, current capacity, forward voltage drop, recovery speed, reverse leakage current, package format, and thermal operating range. Both parts are manufactured using Schottky technology in the DO-219AB Sub SMA package with surface mount configuration.

The key parameters that define substitution eligibility are:

• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io): 1 A
• Voltage - Forward (Vf) (Max) @ If: 900 mV @ 1 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 50 µA @ 150 V
• Package / Case: DO-219AB
• Mounting Type: Surface Mount
• Operating Temperature - Junction: -55°C to 150°C
• Technology: Schottky

Parameter Comparison

Engineering Selection Recommendations

The SS115L is a parametric equivalent to the SS115LHMHG, with all critical electrical and mechanical specifications matching exactly. Both parts share identical voltage ratings, current capacity, forward voltage characteristics, recovery speed, leakage current, package format, and thermal operating range.

The primary distinction between these parts is product status and packaging format. The SS115LHMHG maintains active product status, while the SS115L is designated as "Not For New Designs." This status difference reflects manufacturing lifecycle positioning rather than electrical or mechanical incompatibility.

The SS115L is supplied in Tape & Reel (TR) packaging, whereas the SS115LHMHG is supplied in bulk packaging. This packaging difference affects handling, storage, and automated assembly processes but does not alter component functionality or performance characteristics.

For applications requiring active product status with ongoing manufacturer support, the SS115LHMHG is the appropriate selection. For applications where supply continuity or specific packaging formats are the primary concern, the SS115L provides electrical and mechanical equivalence with identical performance characteristics.

Frequently Asked Questions (FAQ)

Q: Can SS115L be used as a direct replacement for SS115LHMHG in existing designs?

A: Yes. The SS115L is a parametric equivalent with identical electrical specifications including voltage rating (150 V), current capacity (1 A), forward voltage (900 mV @ 1 A), recovery speed (≤ 500ns), and reverse leakage current (50 µA @ 150 V). Both parts use identical Schottky technology in the DO-219AB Sub SMA package with surface mount configuration and matching thermal operating range (-55°C to 150°C).

Q: What is the significance of the "Not For New Designs" status on SS115L?

A: This designation indicates that the SS115L is in a mature or declining phase of its product lifecycle. While the part remains electrically and mechanically equivalent to the SS115LHMHG, the manufacturer does not recommend its use in new design projects. Existing designs using SS115L may continue to source the part, but new applications should prioritize the SS115LHMHG for long-term supply assurance.

Q: Are there packaging differences between SS115LHMHG and SS115L?

A: Yes. The SS115LHMHG is supplied in bulk packaging, while the SS115L is supplied in Tape & Reel (TR) format. This difference affects component handling, storage, and integration with automated assembly equipment. The electrical and mechanical performance of the diode itself remains identical regardless of packaging format.

Q: Do both parts meet automotive qualification requirements?

A: The SS115LHMHG carries automotive-grade classification with AEC-Q101 qualification. The SS115L shares identical electrical and mechanical specifications but does not explicitly list automotive grade or AEC-Q101 qualification in the provided data. Verification of automotive compliance for SS115L should be confirmed through the manufacturer's current documentation.

Q: Are there any compliance or regulatory differences between these parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry identical ECCN (EAR99) and HTSUS (8541.10.0080) classifications. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts. No regulatory or compliance differences exist between the two part numbers.

Q: What is the base product number for these diodes?

A: The base product number for both SS115LHMHG and SS115L is SS115. This base designation identifies the core Schottky diode design with 150 V rating and 1 A capacity. Suffix variations (LHMHG, L) indicate packaging, qualification, or lifecycle status differences while maintaining the same fundamental electrical specifications.
