DSP10G-TR-E Equivalent & Substitute Parts

Part Overview

The DSP10G-TR-E is a general-purpose rectifier diode manufactured by onsemi, rated for 600 V DC reverse voltage and 1 A average rectified current in a surface mount 2-SHP package configuration. This component is classified as obsolete, indicating it has been discontinued and is no longer recommended for new designs. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance or redesign initiatives.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSP10G-TR-E are identified based on electrical and mechanical compatibility within the general-purpose rectifier diode category. The substitution criteria are strictly defined by the following parameters:

Primary Electrical Criteria:

• Voltage - DC Reverse (Vr) (Max): 600 V minimum
• Current - Average Rectified (Io): 1 A minimum
• Voltage - Forward (Vf) (Max) @ If: 1.1 V or lower @ 1 A
• Speed: Standard Recovery >500ns, > 200mA (Io)
• Current - Reverse Leakage @ Vr: 10 µA or lower @ 600 V

Primary Mechanical Criteria:

• Mounting Type: Surface Mount
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

Substitute parts must meet or exceed all electrical specifications and maintain surface mount compatibility. Package variations (DO-219AA, DO-214AC/SMA, DO-219AB) are acceptable provided the physical footprint and lead configuration support direct or minimal-effort board-level substitution.

Parameter Comparison

Engineering Selection Recommendations

MRA4005T3G (onsemi): This substitute maintains identical electrical specifications to the DSP10G-TR-E across all critical parameters: 600 V reverse voltage, 1 A average rectified current, 1.1 V forward voltage drop, and standard recovery speed. The primary difference is the package configuration (DO-214AC/SMA versus DO-219AA), which requires PCB footprint verification. MRA4005T3G carries a "Not For New Designs" status, indicating it is in mature production phase with stable supply. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating. This substitute is suitable for direct electrical replacement in legacy system maintenance where package compatibility can be accommodated.

SE10FJ-M3/H (Vishay General Semiconductor - Diodes Division): This substitute exceeds the electrical specifications of the DSP10G-TR-E in key performance areas: forward voltage drop is reduced to 1.05 V @ 1 A (versus 1.1 V), and reverse leakage current is reduced to 5 µA @ 600 V (versus 10 µA). The operating temperature range is expanded to -55°C ~ 175°C, providing superior thermal performance. SE10FJ-M3/H is classified as Active, indicating current production and long-term availability. The part is ROHS3 compliant with unlimited moisture sensitivity rating. The DO-219AB package is mechanically similar to DO-219AA, supporting direct board-level substitution. This substitute is recommended for applications requiring enhanced performance characteristics and assured long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can MRA4005T3G be used as a direct replacement for DSP10G-TR-E?

A: MRA4005T3G meets all electrical specifications required for substitution. However, the package differs (DO-214AC/SMA versus DO-219AA). Direct PCB compatibility depends on footprint design. Physical verification of lead spacing and pad configuration is required before implementation.

Q: What is the primary advantage of SE10FJ-M3/H over the original DSP10G-TR-E?

A: SE10FJ-M3/H provides superior electrical performance with lower forward voltage drop (1.05 V versus 1.1 V) and reduced reverse leakage current (5 µA versus 10 µA). Additionally, SE10FJ-M3/H is classified as Active, ensuring long-term availability and supply stability, whereas DSP10G-TR-E is obsolete.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both MRA4005T3G and SE10FJ-M3/H are ROHS3 compliant. The original DSP10G-TR-E RoHS status is not specified in available documentation.

Q: What is the difference between DO-219AA, DO-214AC/SMA, and DO-219AB packages?

A: These are distinct surface mount package configurations for rectifier diodes. DO-219AA and DO-219AB are similar form factors with minor dimensional differences. DO-214AC/SMA is a different package footprint. PCB layout compatibility must be verified for each package type before substitution.

Q: Why is MRA4005T3G marked "Not For New Designs"?

A: "Not For New Designs" indicates the part is in mature production phase and available for legacy system support, but onsemi does not recommend it for new circuit designs. SE10FJ-M3/H, classified as Active, is the preferred choice for new applications.

Q: Can SE10FJ-M3/H be used in applications originally designed for DSP10G-TR-E?

A: Yes. SE10FJ-M3/H meets or exceeds all electrical specifications of DSP10G-TR-E and provides enhanced performance. The DO-219AB package is mechanically compatible with DO-219AA, supporting direct substitution. Verify PCB footprint compatibility before implementation.

Q: What is the moisture sensitivity level, and why does it matter?

A: Moisture Sensitivity Level (MSL) 1 (Unlimited) indicates the component has no moisture sensitivity restrictions and requires no special handling or storage conditions. All three parts (DSP10G-TR-E, MRA4005T3G, and SE10FJ-M3/H) carry this rating, ensuring equivalent handling requirements.

Q: Are there any temperature operating range limitations when substituting?

A: DSP10G-TR-E specifies a maximum junction temperature of 150°C. Both substitutes (MRA4005T3G and SE10FJ-M3/H) support -55°C ~ 175°C operating range, providing superior thermal performance. Applications operating near the 150°C limit benefit from the expanded range of substitute parts.
