STTH152 Equivalent & Substitute Parts

Part Overview

The STTH152 is a general-purpose rectifier diode manufactured by STMicroelectronics, rated for 200 V DC reverse voltage and 1.5 A average rectified current in a DO-15 through-hole package. This part is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and ongoing production requirements. Substitute parts must maintain electrical compatibility across voltage, current, and thermal specifications while accommodating package variations in the DO-15 and DO-41 form factors.

Substitute parts are grouped into two categories based on package compatibility:

Category A - DO-15 Package (Direct Mechanical Substitutes): Parts maintaining the original DO-204AC (DO-15) form factor, enabling direct board-level replacement without layout modification.

Category B - DO-41 Package (Functional Equivalents): Parts utilizing the DO-204AL (DO-41) package, requiring PCB footprint adjustment but providing electrical equivalence.

Category C - Enhanced Current Rating: Parts rated for 2 A average rectified current, providing functional substitution with increased current margin in 200 V applications.

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

GP15D-E3/54 and GP15D-E3/73 are the preferred substitutes for the STTH152. Both parts are manufactured by Vishay General Semiconductor, maintain the DO-15 package form factor, and are rated for 200 V and 1.5 A. Both achieve the maximum junction temperature of 175°C and carry ROHS3 compliance. These parts enable direct mechanical replacement without PCB modification. Inventory availability is 4409 units (GP15D-E3/54) and 840 units (GP15D-E3/73).

Secondary Substitutes (Active Status, Package Variation):

STTH1R02 is an active STMicroelectronics part offering 200 V and 1.5 A ratings with a 175°C maximum junction temperature. This part utilizes the DO-41 package, requiring PCB footprint adjustment. The reverse recovery time of 30 ns closely matches the STTH152 specification. Inventory availability is 1148 units.

FR153GP-AP is an active Micro Commercial Co part maintaining the DO-15 package with 200 V and 1.5 A ratings. The maximum junction temperature is 150°C, which is lower than the STTH152 specification. This part is suitable for applications with reduced thermal margins. Inventory availability is 990 units.

Functional Equivalent (Enhanced Current Rating):

SF24GHB0G is an active Taiwan Semiconductor Corporation part rated for 200 V and 2 A, providing increased current capacity in the DO-15 package. The maximum junction temperature is 150°C. This part is qualified to AEC-Q101 automotive standards and is suitable for applications requiring higher current margins. Inventory availability is 797 units.

Not Recommended:

1N5393-E3/54 is an active Vishay part rated for 200 V and 1.5 A in the DO-41 package. The maximum junction temperature is 150°C, and the reverse recovery time is 2000 ns, which represents a significant departure from the STTH152 fast recovery specification. This part is classified as standard recovery technology and is suitable only for applications where recovery speed is not a design constraint.

Frequently Asked Questions (FAQ)

Q: Can the STTH152 be directly replaced with STTH1R02?

A: The STTH1R02 provides electrical equivalence at 200 V and 1.5 A with a 175°C maximum junction temperature. However, the STTH1R02 uses the DO-41 package, while the STTH152 uses the DO-15 package. Direct board-level replacement is not possible without PCB footprint modification. The two packages have different lead spacing and mechanical dimensions.

Q: What is the difference between fast recovery and standard recovery diodes in this comparison?

A: The STTH152 specifies fast recovery with a reverse recovery time of 32 ns. The GP15D-E3/54 and GP15D-E3/73 specify standard recovery with a reverse recovery time of 3500 ns. The 1N5393-E3/54 specifies standard recovery with a reverse recovery time of 2000 ns. Fast recovery diodes are suitable for high-frequency switching applications, while standard recovery diodes are suitable for lower-frequency rectification. Application requirements determine which recovery speed is appropriate.

Q: Is the SF24GHB0G suitable as a substitute despite the 2 A rating?

A: The SF24GHB0G is rated for 2 A average rectified current, compared to the STTH152 at 1.5 A. This represents a higher current capacity and does not create a compatibility issue. The part maintains 200 V voltage rating, DO-15 package form factor, and ROHS3 compliance. The maximum junction temperature is 150°C, which is lower than the STTH152 specification. The SF24GHB0G is qualified to AEC-Q101 automotive standards.

Q: What is the significance of the DO-15 and DO-41 package designations?

A: DO-15 (DO-204AC) and DO-41 (DO-204AL) are standardized through-hole axial package designations for diodes. Both are cylindrical with axial leads, but they differ in physical dimensions and lead spacing. DO-15 is smaller than DO-41. PCB footprints are specific to each package type. Substitution between packages requires PCB redesign.

Q: Are all substitute parts RoHS3 compliant?

A: All substitute parts listed in this document are RoHS3 compliant and REACH unaffected, matching the compliance status of the STTH152. All parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: What is the operating temperature range consideration for substitution?

A: The STTH152 specifies a maximum junction temperature of 175°C. The GP15D-E3/54, GP15D-E3/73, and STTH1R02 all achieve this specification. The FR153GP-AP, 1N5393-E3/54, and SF24GHB0G specify maximum junction temperatures of 150°C. For applications operating near thermal limits, the 175°C-rated parts are preferred. For applications with adequate thermal margin, the 150°C-rated parts are acceptable.

Q: Can the 1N5393-E3/54 be used in high-frequency switching applications?

A: The 1N5393-E3/54 specifies standard recovery technology with a reverse recovery time of 2000 ns. This part is not suitable for high-frequency switching applications where fast recovery characteristics are required. The STTH152 specifies fast recovery at 32 ns. For high-frequency applications, the STTH1R02 (30 ns), FR153GP-AP (150 ns), or SF24GHB0G (35 ns) are appropriate selections.
