Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the SF1605PTHC0G are qualified based on the following electrical and mechanical parameters:

Primary Substitution Criteria:

• Voltage - DC Reverse (Vr) (Max): 300 V minimum
• Mounting Type: Through Hole
• Package / Case: TO-247-3 compatible
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA

Secondary Compatibility Factors:

• Current - Average Rectified (Io): Equal to or greater than 16 A
• RoHS Status: ROHS3 Compliant
• Operating Temperature Range: Support for -55°C to 150°C junction temperature

The identified substitute parts (STTH60P03SW and STTH6003CW) meet or exceed the primary electrical specifications while maintaining mechanical compatibility through identical TO-247-3 packaging and through-hole mounting. Both substitutes are manufactured by STMicroelectronics and carry ROHS3 compliance status.

Parameter Comparison

Engineering Selection Recommendations

SF1605PTHC0G (Primary Component): The SF1605PTHC0G is suitable for applications requiring 16 A rectification at 300 V with automotive-grade qualification (AEC-Q101). This component is recommended for designs with established supply chain relationships with Taiwan Semiconductor Corporation and where the 16 A current rating is the design specification.

STTH60P03SW (Substitute - Higher Current Capacity): The STTH60P03SW provides 60 A average rectified current at 300 V in the same TO-247-3 package. This substitute is applicable when higher current capacity is required or when supply availability from STMicroelectronics is preferred. The higher maximum junction temperature (175°C) provides additional thermal margin. This component is suitable for designs where current requirements may exceed 16 A.

STTH6003CW (Substitute - Dual Diode Configuration): The STTH6003CW is a dual diode array (1 Pair Common Cathode) with 30 A per diode at 300 V. This configuration is applicable for bridge rectifier implementations or dual-channel rectification requirements. The common cathode configuration requires circuit topology compatibility. This substitute is suitable for applications requiring dual rectification paths within a single package.

All substitute parts maintain ROHS3 compliance and Active product status. Selection between substitutes depends on circuit topology requirements, current capacity needs, and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can STTH60P03SW directly replace SF1605PTHC0G in a single-diode rectification circuit?

A: Yes. The STTH60P03SW maintains identical voltage rating (300 V), package type (TO-247-3), and mounting method (through-hole). The higher current rating (60 A versus 16 A) does not prevent substitution in circuits designed for 16 A operation. The component will operate within its rated specifications at lower current levels.

Q: What is the key difference between STTH60P03SW and STTH6003CW?

A: STTH60P03SW is a single diode rated 60 A. STTH6003CW is a dual diode array with common cathode configuration, rated 30 A per diode. STTH6003CW requires circuit topology compatible with dual-diode common-cathode configuration and is not a direct pin-for-pin replacement in single-diode applications.

Q: Are all three parts suitable for automotive applications?

A: SF1605PTHC0G carries AEC-Q101 automotive qualification. STTH60P03SW and STTH6003CW do not list AEC-Q101 qualification in the provided specifications. Applications requiring automotive qualification should verify qualification status with STMicroelectronics or maintain SF1605PTHC0G as the primary component.

Q: What is the impact of higher reverse leakage current in substitute parts?

A: SF1605PTHC0G specifies 10 µA reverse leakage at 300 V. STTH60P03SW specifies 100 µA, and STTH6003CW specifies 60 µA. Higher reverse leakage increases standby power dissipation and may affect circuit performance in high-impedance applications. Circuit design should account for these differences in leakage current specifications.

Q: Can the SF1605PTHC0G be used in applications designed for STTH60P03SW?

A: The SF1605PTHC0G can be used in circuits designed for STTH60P03SW when the circuit current requirement does not exceed 16 A. The SF1605PTHC0G meets all voltage and package requirements. However, thermal design margins may be reduced due to lower current capacity and lower maximum junction temperature (150°C versus 175°C).

Q: Are there package compatibility concerns when substituting between these parts?

A: All three parts use TO-247-3 through-hole packaging. Physical dimensions and pin configurations are compatible. No package-related modifications to PCB layout or mounting hardware are required for substitution.
