STTH16L06CFP Equivalent & Substitute Parts

Part Overview

The STTH16L06CFP is a general-purpose diode array manufactured by STMicroelectronics, configured as a 1 Pair Common Cathode rectifier with 600 V reverse voltage rating and 8 A average rectified current per diode. The device is packaged in TO-220-3 Full Pack through-hole configuration and is classified as Active product status with ROHS3 compliance.

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the specified parameters. Alternative sources may be required due to inventory availability, supply chain considerations, or specific application requirements within the defined electrical and mechanical constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the STTH16L06CFP is determined by the following critical parameters:

Mandatory Matching Criteria:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 600 V minimum
• Mounting Type: Through Hole
• Package / Case: TO-220-3 compatible footprint
• Technology: Standard rectifier diode technology
• RoHS Status: ROHS3 Compliant

Performance Parameters (Allowable Variation):

• Current - Average Rectified (Io): Equal to or greater than 8 A per diode
• Voltage - Forward (Vf): Equal to or less than 1.8 V @ 8 A
• Reverse Recovery Time (trr): Equal to or less than 55 ns
• Current - Reverse Leakage @ Vr: Equal to or less than 8 µA @ 600 V
• Operating Temperature - Junction: Equal to or greater than 175°C maximum

The ER1606CT_T0_00001 meets all mandatory matching criteria and exceeds performance specifications in current rating, forward voltage, reverse recovery time, and reverse leakage characteristics.

Parameter Comparison

Engineering Selection Recommendations

STTH16L06CFP (Primary Selection): The STTH16L06CFP remains the primary component choice when the specified electrical and thermal characteristics are required. This part is manufactured by STMicroelectronics, carries Active product status, and maintains ROHS3 compliance. The device supports a maximum junction temperature of 175°C and provides the baseline performance specifications for 600 V, 8 A rectifier applications.

ER1606CT_T0_00001 (Substitute Selection): The ER1606CT_T0_00001 manufactured by Panjit International Inc. is a qualified substitute when the STTH16L06CFP is unavailable. This part maintains identical diode configuration, reverse voltage rating, and mounting type. The substitute provides superior performance in current capacity (16 A versus 8 A), forward voltage (1.7 V versus 1.8 V @ 8 A), and reverse recovery time (35 ns versus 55 ns). Both parts carry ROHS3 compliance and Active product status.

Thermal Consideration: The ER1606CT_T0_00001 specifies a maximum junction temperature of 150°C, which is 25°C lower than the STTH16L06CFP. Applications requiring sustained operation at junction temperatures between 150°C and 175°C must retain the STTH16L06CFP.

Packaging Compatibility: Both parts utilize TO-220-3 through-hole packaging. The STTH16L06CFP is supplied in TO-220-3 Full Pack configuration, while the ER1606CT_T0_00001 uses TO-220-3 standard configuration. Both footprints are mechanically compatible for PCB mounting.

Frequently Asked Questions (FAQ)

Q: Can the ER1606CT_T0_00001 directly replace the STTH16L06CFP in all applications?

A: The ER1606CT_T0_00001 is electrically and mechanically compatible for applications operating at junction temperatures up to 150°C. Applications requiring sustained operation above 150°C must use the STTH16L06CFP, which is rated to 175°C maximum junction temperature.

Q: What is the significance of the higher current rating (16 A) on the substitute part?

A: The ER1606CT_T0_00001 is rated for 16 A average rectified current per diode, compared to 8 A on the STTH16L06CFP. This higher rating provides additional design margin and thermal headroom in applications requiring 8 A operation. The substitute part will not degrade performance in circuits designed for the lower current specification.

Q: Are the TO-220-3 Full Pack and TO-220-3 packages interchangeable?

A: Both packages utilize the same TO-220-3 footprint and are mechanically compatible for through-hole PCB mounting. The "Full Pack" designation on the STTH16L06CFP refers to packaging configuration and does not affect electrical or mechanical compatibility.

Q: What does the lower reverse recovery time (35 ns versus 55 ns) mean for circuit performance?

A: Reverse recovery time (trr) defines the interval required for a diode to transition from forward conduction to reverse blocking. The ER1606CT_T0_00001 exhibits faster switching characteristics, which reduces switching losses and may improve efficiency in high-frequency rectification circuits. This represents an improvement over the STTH16L06CFP specification.

Q: Are both parts RoHS compliant?

A: Yes. Both the STTH16L06CFP and ER1606CT_T0_00001 carry ROHS3 Compliant status and are suitable for applications requiring RoHS compliance.

Q: What is the difference in reverse leakage current between the two parts?

A: The STTH16L06CFP specifies 8 µA reverse leakage at 600 V, while the ER1606CT_T0_00001 specifies 1 µA at the same voltage. Lower reverse leakage current reduces standby power consumption and improves circuit efficiency, particularly in applications with extended idle periods.
