STTH30L06PI Equivalent & Substitute Parts

Part Overview

The STTH30L06PI is a general-purpose rectifier diode manufactured by STMicroelectronics, rated for 600 V DC reverse voltage and 30 A average rectified current. This component features fast recovery characteristics with a reverse recovery time of 90 ns, making it suitable for high-frequency rectification applications. The device is packaged in a DOP3I-2 insulated through-hole configuration with straight leads.

The STTH30L06PI is classified as obsolete. Locating equivalent substitute parts is necessary to support ongoing production requirements, maintenance operations, and system redesigns where component availability is constrained. The substitute part identified maintains electrical equivalence while offering improved market availability and active product status.

Substitute Part Grouping Explanation

Substitution of the STTH30L06PI is determined by electrical and mechanical parameter equivalence within the rectifier diode category. The following criteria establish valid substitution:

Electrical Equivalence Requirements:

• Voltage - DC Reverse (Vr) (Max): 600 V
• Current - Average Rectified (Io): 30 A
• Voltage - Forward (Vf) (Max) @ If: 1.55 V @ 30 A
• Reverse Recovery Time (trr): 90 ns
• Current - Reverse Leakage @ Vr: 25 µA @ 600 V
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• Operating Temperature - Junction (Max): 175°C

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole
• Base Product Number: STTH30 (same device family)
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The STTH30L06W qualifies as a direct electrical substitute. While the package configuration differs (DO-247 versus DOP3I), both are through-hole mounted devices with identical electrical performance specifications and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The STTH30L06W is the qualified substitute for the STTH30L06PI based on the following factors:

Product Status Consideration: The STTH30L06PI is classified as obsolete, while the STTH30L06W maintains active product status with STMicroelectronics. This status difference ensures long-term availability and supply chain continuity for the substitute part.

Electrical Equivalence: All critical electrical parameters are identical between the two devices: reverse voltage rating, average rectified current, forward voltage drop, reverse recovery time, and reverse leakage current. Both devices operate within the same temperature range and exhibit identical fast recovery characteristics.

Compliance and Certification: Both parts carry identical regulatory certifications: ROHS3 compliance, REACH unaffected status, and EAR99 export classification. Moisture sensitivity levels are equivalent at MSL 1 (unlimited), indicating no special handling requirements.

Package Consideration: The primary difference between the STTH30L06PI and STTH30L06W is the through-hole package configuration. The STTH30L06PI uses DOP3I-2 packaging, while the STTH30L06W uses DO-247-2 packaging. Both are through-hole mounted devices with straight leads. PCB layout modifications may be required to accommodate the different package footprints.

Frequently Asked Questions (FAQ)

Q: Can the STTH30L06W be used as a direct replacement for the STTH30L06PI without circuit modifications?

A: The STTH30L06W is electrically equivalent to the STTH30L06PI. However, the package footprint differs (DO-247-2 versus DOP3I-2). PCB layout changes are necessary to accommodate the different lead spacing and package dimensions. Electrical circuit operation remains unchanged.

Q: What is the primary reason for substituting the STTH30L06PI?

A: The STTH30L06PI is classified as obsolete. The STTH30L06W is an active product with equivalent electrical specifications and superior market availability, making it the appropriate choice for new designs and ongoing production support.

Q: Are there any performance differences between the STTH30L06PI and STTH30L06W?

A: No performance differences exist. Both devices share identical electrical ratings, including reverse voltage (600 V), average rectified current (30 A), forward voltage drop (1.55 V @ 30 A), reverse recovery time (90 ns), and reverse leakage current (25 µA @ 600 V).

Q: Do both parts require the same handling and storage procedures?

A: Yes. Both the STTH30L06PI and STTH30L06W carry identical moisture sensitivity levels (MSL 1 - Unlimited), indicating no special moisture control requirements during storage or handling.

Q: What compliance certifications apply to the STTH30L06W?

A: The STTH30L06W is ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. These certifications match those of the STTH30L06PI.

Q: Is the STTH30L06W available in the same packaging options as the STTH30L06PI?

A: No. The STTH30L06PI is supplied in DOP3I-2 packaging, while the STTH30L06W is supplied in DO-247-2 packaging. Both are through-hole configurations with straight leads, but the physical dimensions and lead spacing differ.

Q: What is the inventory status of the STTH30L06W?

A: The STTH30L06W is actively manufactured and maintained in stock with significantly higher inventory levels (63,600 pieces) compared to the obsolete STTH30L06PI (1,400 pieces).
