S6016NTP Equivalent & Substitute Parts

Part Overview

The S6016NTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc., rated for 600V off-state voltage with 16A RMS on-state current capability. This thyristor is designed for surface mount applications in the TO-263 (D2PAK) package and is currently in active production status. The component is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Alternative equivalent parts may be required due to inventory constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility within the defined parameter ranges.

Substitute Part Grouping Explanation

Substitution eligibility for the S6016NTP is determined by the following critical parameters:

Voltage Rating (Off State): Must equal 600V to ensure blocking capability in the application circuit
Package / Case: Must be TO-263-3 or D2PAK (2 Leads + Tab) to maintain mechanical and thermal compatibility
Mounting Type: Must be Surface Mount to ensure PCB assembly compatibility
SCR Type: Must be Standard Recovery to match switching characteristics
On-State Current (It RMS): Substitute must support the required current level for the application
Gate Trigger Parameters: Must be within acceptable ranges for gate drive circuit compatibility
Operating Temperature: Must cover the application's thermal requirements
Compliance: Must maintain ROHS3 compliance and equivalent certifications

The two substitute parts listed below meet these criteria with variations in current handling capacity and gate trigger characteristics.

Engineering Selection Recommendations

TN1205H-6G-TR (STMicroelectronics) is suitable for applications where the required on-state current does not exceed 12A RMS. This substitute offers lower gate trigger current (5mA vs 30mA), which may reduce gate drive circuit complexity. The extended operating temperature range to 150°C provides additional thermal margin. This part is appropriate for lower-current variants of the original application.

TN2540-600G-TR (STMicroelectronics) is suitable for applications requiring higher on-state current capacity up to 25A RMS, providing design margin above the original 16A specification. This substitute maintains the same 600V voltage rating and D2PAK package compatibility. The gate trigger current specification (40mA) is closer to the original part. This part is appropriate for higher-current or thermally demanding applications.

Both substitutes maintain ROHS3 compliance, equivalent certifications (REACH Unaffected, EAR99), and identical package specifications (TO-263-3, D2PAK). Selection between substitutes depends on the specific current requirements of the target application circuit.

Frequently Asked Questions (FAQ)

Q: Can TN1205H-6G-TR replace S6016NTP in all applications?

A: TN1205H-6G-TR is electrically compatible for applications requiring 12A RMS or less. Applications designed for the full 16A RMS capability of the S6016NTP require TN2540-600G-TR or equivalent higher-current rated devices.

Q: Are the D2PAK packages physically identical between these parts?

A: Yes. All three parts use TO-263-3 D2PAK (2 Leads + Tab) packaging with identical mechanical dimensions and PCB footprints, enabling direct board-level substitution without layout modifications.

Q: What is the impact of different gate trigger current specifications?

A: Gate trigger current (Igt) affects gate drive circuit design. TN1205H-6G-TR requires 5mA maximum, while S6016NTP and TN2540-600G-TR require 30mA and 40mA respectively. Lower Igt values allow simpler gate drive implementations with reduced power consumption.

Q: Do all three parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Moisture sensitivity level is MSL 1 (unlimited) for all parts.

Q: Which substitute offers the best thermal performance?

A: TN1205H-6G-TR provides the widest operating temperature range (-40°C to 150°C) compared to S6016NTP and TN2540-600G-TR (-40°C to 125°C), offering additional thermal margin in high-temperature environments.
