Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSF30H150C is determined by strict alignment of the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Diode Configuration: 1 Pair Common Cathode (exact match required)
• Voltage - DC Reverse (Vr) (Max): 150 V (exact match required)
• Current - Average Rectified (Io) (per Diode): 15 A or greater (equal or higher rating acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: TO-220-3 Full Pack, Isolated Tab (exact match required)
• Supplier Device Package: ITO-220AB (exact match required)
• Technology: Schottky (exact match required)
• Speed: Fast Recovery ≤ 500 ns, > 200 mA (Io) (exact match required)
• Operating Temperature - Junction: −55°C to 150°C (exact match required)

Secondary Compliance Criteria:

• RoHS3 Compliance (required for regulatory alignment)
• Moisture Sensitivity Level MSL 1 (required for handling compatibility)

Substitute parts are grouped into two categories:

Category A - Direct Equivalents (Common Cathode, 15 A Rating): Parts with identical current rating (15 A) and common cathode configuration. These provide direct functional replacement with minimal circuit redesign consideration.

Category B - Higher Current Rated Substitutes (Common Cathode, 20 A Rating): Parts rated for 20 A average rectified current. These are electrically compatible and provide enhanced current handling capability within the same package and configuration.

Category C - Lower Current Rated Substitutes (Common Cathode, 10 A or 5 A Rating): Parts rated for 10 A or 5 A average rectified current. These are electrically compatible but with reduced current capacity and are suitable only for applications with lower current requirements than the original 15 A specification.

Excluded from Substitution:

• STF20150CR (Common Anode configuration; incompatible with Common Cathode requirement)

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Identical Current Rating):

VF30150C-E3/4W is the primary recommended substitute. This part is manufactured by Vishay General Semiconductor - Diodes Division, carries Active product status, and maintains the 15 A average rectified current rating of the original TSF30H150C. Both parts are ROHS3 compliant and MSL 1 rated. The part is available in high inventory (20,978 pcs). Forward voltage specification is 1.36 V @ 15 A, compared to 900 mV @ 15 A for the original part; this difference reflects typical manufacturing variations between suppliers and does not preclude functional substitution in standard rectifier applications.

STF30150C from SMC Diode Solutions is an alternative direct equivalent, also rated for 15 A with Active product status and ROHS3 compliance. This part carries REACH Affected status, which may require additional regulatory documentation in certain supply chain contexts.

For Higher Current Applications:

VF40150C-E3/4W and VF40150C-M3/4W are suitable for applications requiring enhanced current capacity. Both are rated for 20 A average rectified current, maintain the 150 V reverse voltage specification, and carry Active product status with REACH Unaffected designation. These parts are electrically compatible with the TSF30H150C in applications where the original 15 A rating is conservative or where future current margin is required.

For Current-Limited Applications:

VF20150C-E3/4W and VF20150C-M3/4W are suitable for applications with maximum current requirements of 10 A. Both maintain the 150 V reverse voltage and Active product status. These parts are appropriate for designs where the original 15 A specification exceeds application requirements.

VF10150C-E3/4W is suitable only for applications with maximum current requirements of 5 A and should be selected only when circuit design explicitly limits current to this level.

Compliance and Regulatory Considerations:

All recommended substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard handling and environmental requirements. Parts with REACH Unaffected status (Vishay products) present no additional regulatory burden. The STF30150C carries REACH Affected status; verification of supply chain documentation is required for applications subject to REACH regulation.

Frequently Asked Questions (FAQ)

Q: Can STF20150CR be used as a substitute for TSF30H150C?

A: No. STF20150CR is configured as 1 Pair Common Anode, while TSF30H150C is 1 Pair Common Cathode. These configurations are electrically incompatible and cannot be interchanged without circuit redesign. The diode configuration is a primary substitution criterion.

Q: What is the difference between VF30150C-E3/4W and VF30150C-M3/4W?

A: Both parts are electrically identical with 15 A current rating, 150 V reverse voltage, and identical forward voltage specifications. The designation suffix (-E3/4W versus -M3/4W) indicates different manufacturing or packaging variants from Vishay. Both are suitable direct substitutes for TSF30H150C.

Q: Can VF40150C-E3/4W be used in place of TSF30H150C?

A: Yes. VF40150C-E3/4W is rated for 20 A average rectified current, which exceeds the 15 A requirement of TSF30H150C. The higher current rating provides additional design margin and is electrically compatible. All other parameters (150 V reverse voltage, Common Cathode configuration, TO-220-3 package, fast recovery speed, operating temperature range) are identical. This substitution is appropriate for applications where enhanced current capacity is beneficial or required.

Q: Can VF20150C-E3/4W be used in place of TSF30H150C?

A: VF20150C-E3/4W is rated for 10 A average rectified current, which is lower than the 15 A specification of TSF30H150C. This part is suitable only for applications where circuit design limits current to 10 A or less. If the original application requires 15 A capability, VF20150C-E3/4W is not appropriate. Verify application current requirements before selecting this substitute.

Q: Are all substitute parts available in the same TO-220-3 package?

A: Yes. All substitute parts listed are packaged in TO-220-3 Full Pack with isolated tab (ITO-220AB supplier device package). Physical mounting and thermal interface characteristics are identical to TSF30H150C. No PCB layout modifications are required for package compatibility.

Q: What is the significance of the forward voltage difference between TSF30H150C (900 mV @ 15 A) and VF30150C-E3/4W (1.36 V @ 15 A)?

A: The forward voltage difference reflects typical manufacturing variations between Taiwan Semiconductor Corporation and Vishay. Both values are within acceptable ranges for Schottky diode rectifier applications. The higher forward voltage of the Vishay part results in slightly increased power dissipation; thermal design should be verified if the original design operated near thermal limits. For most standard rectifier applications, this difference does not preclude functional substitution.

Q: Is RoHS3 compliance maintained across all substitute parts?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of TSF30H150C. No regulatory or environmental qualification changes are required for substitution.

Q: What does "REACH Affected" versus "REACH Unaffected" mean for part selection?

A: REACH Affected status indicates the part may contain substances subject to REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulation. REACH Unaffected status indicates no such substances are present. For applications subject to REACH compliance requirements, parts with REACH Unaffected status (Vishay products) are preferred. Parts with REACH Affected status (STF30150C) require additional supply chain documentation and verification. Selection depends on application regulatory requirements.

Q: Can TSF30H150C be used in new designs?

A: No. TSF30H150C carries "Not For New Designs" product status, indicating the part is obsolete or being phased out by the manufacturer. New designs must select from Active status parts. VF30150C-E3/4W is the recommended substitute for new designs requiring 15 A capability.
