STTH3002PI Equivalent & Substitute Parts

Part Overview

The STTH3002PI is a general-purpose rectifier diode manufactured by STMicroelectronics, rated for 200 V DC reverse voltage and 30 A average rectified current. The device features fast recovery characteristics with a reverse recovery time of 50 ns and is housed in a DOP3I-2 insulated through-hole package with straight leads. The STTH3002PI is classified as obsolete, necessitating identification of active equivalent components for new designs and ongoing production requirements. Substitute parts must maintain electrical and mechanical compatibility while meeting current availability and compliance standards.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the STTH3002PI is determined by the following critical parameters:

Mechanical Compatibility: Mounting type (through hole) and package designation (DOP3I-2 insulated with straight leads) must be identical to ensure physical fit and thermal management in existing PCB layouts.

Electrical Compatibility: Current rating (30 A average rectified) must be maintained or exceeded. Voltage rating must equal or exceed the 200 V DC reverse voltage specification to ensure safe operation within the application's voltage envelope. Forward voltage drop and reverse recovery time characteristics must be compatible with circuit performance requirements.

Technology and Speed: Fast recovery classification (≤ 500ns, > 200mA) must be preserved to maintain switching performance in rectification applications.

Compliance and Status: Substitute parts must carry active product status and maintain RoHS3 compliance and REACH unaffected designation to support current manufacturing and regulatory requirements.

The STTH3006DPI meets these substitution criteria through identical mechanical packaging, matching current rating, higher voltage rating (600 V), and active product status, while maintaining fast recovery characteristics and compliance certifications.

Engineering Selection Recommendations

The STTH3006DPI serves as the direct substitute for the obsolete STTH3002PI based on the following engineering criteria:

Product Availability: The STTH3002PI is classified as obsolete with limited inventory (790 pcs). The STTH3006DPI maintains active product status with substantial inventory availability (13,599 pcs), ensuring long-term supply chain continuity for production and design cycles.

Mechanical Compatibility: Both devices utilize identical DOP3I-2 insulated through-hole packaging with straight leads, enabling direct PCB layout compatibility without redesign or rework.

Electrical Compatibility: The STTH3006DPI maintains the 30 A average rectified current rating and fast recovery characteristics (45 ns trr) of the original device. The elevated voltage rating (600 V versus 200 V) provides enhanced overvoltage margin and is suitable for applications operating at or below 200 V DC reverse voltage.

Compliance Alignment: Both devices carry ROHS3 compliance and REACH unaffected designation, meeting current regulatory and manufacturing standards.

Circuit Performance Considerations: The STTH3006DPI exhibits a higher forward voltage drop (3.6 V @ 30 A versus 1.05 V @ 30 A) and lower maximum junction temperature (150°C versus 175°C). These parameters must be evaluated within the specific application context to confirm thermal and power dissipation compatibility.

Frequently Asked Questions (FAQ)

Q: Can the STTH3006DPI be used in all applications designed for the STTH3002PI?

A: The STTH3006DPI is mechanically and electrically compatible for applications operating at or below 200 V DC reverse voltage. The higher forward voltage drop and lower maximum junction temperature must be evaluated for thermal management and power dissipation in the specific circuit design.

Q: What is the primary difference between the STTH3002PI and STTH3006DPI?

A: The primary difference is the maximum DC reverse voltage rating: 200 V for the STTH3002PI and 600 V for the STTH3006DPI. This results in a higher forward voltage drop in the STTH3006DPI (3.6 V versus 1.05 V at 30 A) due to the additional semiconductor material required for higher voltage blocking capability.

Q: Are the packages identical between these two devices?

A: Yes. Both devices use the DOP3I-2 insulated through-hole package with straight leads, ensuring identical mechanical fit and thermal characteristics on the PCB.

Q: Why is the STTH3002PI classified as obsolete?

A: The STTH3002PI is obsolete according to STMicroelectronics product status. The STTH3006DPI is the active equivalent offering superior voltage rating and current availability.

Q: What compliance certifications apply to the STTH3006DPI?

A: The STTH3006DPI carries ROHS3 compliance and REACH unaffected designation, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: How do the reverse recovery times compare?

A: The STTH3006DPI has a slightly faster reverse recovery time (45 ns) compared to the STTH3002PI (50 ns). Both devices meet the fast recovery classification (≤ 500ns, > 200mA), ensuring compatible switching performance in rectification circuits.
