DLA11C-TR-E Equivalent & Substitute Parts

Part Overview

The DLA11C-TR-E is a general-purpose rectifier diode manufactured by onsemi, rated for 200 V DC reverse voltage and 1.1 A average rectified current in a 2-SMD J-Lead surface mount package. The device features fast recovery characteristics with a reverse recovery time of 50 ns and operates at a maximum junction temperature of 150°C.

This part is classified as obsolete. Identifying equivalent and substitute components is necessary to support ongoing design requirements, system maintenance, and procurement continuity where the original part is no longer available through standard distribution channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DLA11C-TR-E is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Voltage - DC Reverse (Vr) rating must equal or exceed 200 V
• Current - Average Rectified (Io) rating must equal or exceed 1.1 A
• Forward voltage (Vf) characteristics must be compatible with circuit design
• Reverse recovery time (trr) must support the intended switching frequency and application speed requirements
• Reverse leakage current must remain within acceptable limits for the application

Mechanical Compatibility Criteria:

• Mounting type must be Surface Mount
• Package footprint and lead configuration must be compatible with PCB layout
• Moisture Sensitivity Level (MSL) rating must be acceptable for storage and assembly conditions

Compliance Criteria:

• REACH and RoHS status must meet regulatory requirements for the target application
• ECCN classification must align with export control requirements

Two substitute parts meet the electrical requirements while offering different package configurations and performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

VS-2EJH02-M3/6A (Vishay):

This substitute provides full electrical compatibility with the DLA11C-TR-E. The 200 V reverse voltage rating matches the original specification exactly. The 2 A current rating exceeds the 1.1 A requirement, providing design margin. The reverse recovery time of 25 ns is superior to the original 50 ns specification, enabling faster switching performance. The forward voltage of 930 mV at 2 A is lower than the original 980 mV at 1.1 A, reducing power dissipation. The part is active and ROHS3 compliant, supporting long-term availability and regulatory compliance. The DO-221AC (SlimSMA) package differs from the original 2-SMD J-Lead configuration and requires PCB layout verification for mechanical compatibility.

MURA115T3G (onsemi):

This substitute is from the same manufacturer as the original part, providing design continuity. However, the 150 V reverse voltage rating is below the 200 V specification of the DLA11C-TR-E. This part is suitable only for applications where the circuit operates at 150 V or lower. The 1 A current rating is slightly below the 1.1 A requirement. The reverse recovery time of 35 ns is faster than the original 50 ns. The part is active and ROHS3 compliant. The DO-214AC (SMA) package differs from the original configuration and requires PCB layout verification.

Selection Guidance:

For applications requiring the full 200 V rating and 1.1 A current capacity, the VS-2EJH02-M3/6A is the appropriate substitute. For applications operating at 150 V or lower with current requirements at or below 1 A, the MURA115T3G provides an alternative from the original manufacturer. Both substitutes are active products with current availability and regulatory compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can the MURA115T3G replace the DLA11C-TR-E in all applications?

A: No. The MURA115T3G has a maximum reverse voltage rating of 150 V, which is 50 V below the DLA11C-TR-E specification of 200 V. This part is suitable only for circuits designed to operate at 150 V or lower. For applications requiring the full 200 V rating, the VS-2EJH02-M3/6A is the appropriate substitute.

Q: What are the package differences between the substitutes and the original part?

A: The DLA11C-TR-E uses a 2-SMD J-Lead package. The VS-2EJH02-M3/6A uses a DO-221AC (SlimSMA) package with flat leads. The MURA115T3G uses a DO-214AC (SMA) package. These package differences require verification of PCB footprint compatibility and assembly process compatibility before implementation.

Q: Are both substitute parts actively manufactured?

A: Yes. Both the VS-2EJH02-M3/6A and MURA115T3G are classified as active products with current manufacturing status. The original DLA11C-TR-E is obsolete and no longer manufactured.

Q: Do the substitute parts meet the same regulatory requirements as the original?

A: Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory standards. The original part status for these certifications is not specified. Both substitutes carry the same ECCN classification (EAR99) as the original.

Q: How do the electrical characteristics of the substitutes compare to the original?

A: The VS-2EJH02-M3/6A exceeds the original specifications in current capacity (2 A vs. 1.1 A) and reverse recovery time (25 ns vs. 50 ns), while matching the 200 V voltage rating. The MURA115T3G has a lower voltage rating (150 V vs. 200 V) and slightly lower current capacity (1 A vs. 1.1 A), but offers faster reverse recovery (35 ns vs. 50 ns).

Q: What is the moisture sensitivity level for the substitute parts?

A: Both substitute parts have an MSL rating of 1 (Unlimited), matching the original part. This indicates no moisture sensitivity restrictions for storage and assembly.

Q: Can the higher current rating of the VS-2EJH02-M3/6A cause issues in the circuit?

A: No. A higher current rating does not cause circuit issues. The diode will operate within its rated parameters when used in a circuit designed for the original 1.1 A specification. The higher rating provides design margin and improved reliability.
