TIC236M-S TRIAC 600V 12A Equivalent & Substitute Parts

Part Overview

The TIC236M-S is a standard TRIAC thyristor rated for 600V off-state voltage and 12A on-state current in a TO-220-3 through-hole package. Manufactured by Bourns Inc., this component is classified as obsolete. Due to its obsolete status and limited availability from the original manufacturer, identifying equivalent substitute parts with compatible electrical and mechanical specifications is necessary for design continuity and procurement flexibility.

Substitute Part Grouping Explanation

Substitute parts for the TIC236M-S are qualified based on the following criteria:

Electrical Compatibility:

Off-state voltage rating of 600V or higher
Gate trigger voltage (Vgt) of 2V or lower
Gate trigger current (Igt) of 50mA or lower
Hold current (Ih) of 40mA or lower
Single configuration

Mechanical Compatibility:

Through-hole mounting type
TO-220-3 package / case designation

Regulatory Compliance:

ROHS3 compliance required

The substitute parts identified meet these criteria while accommodating variations in on-state current ratings and operating temperature ranges within the allowed parameter envelope.

Engineering Selection Recommendations

Both 2N6344G and MAC210A8G are active-status alternatives from Littelfuse with full ROHS3 compliance. The 2N6344G provides 8A on-state current, while the MAC210A8G provides 10A on-state current. Both meet the electrical trigger specifications and hold-current requirements of the TIC236M-S. The extended operating temperature range (-40°C to 125°C) of both substitutes exceeds the original part's specification. Selection between these alternatives depends on the specific on-state current requirement of the application circuit.

Frequently Asked Questions (FAQ)

Q: Can 2N6344G or MAC210A8G directly replace TIC236M-S in existing designs?

A: Both parts share identical off-state voltage (600V), gate trigger voltage (2V maximum), and gate trigger current (50mA maximum) specifications. Both are packaged in TO-220-3 through-hole format. The primary difference is on-state current rating: 2N6344G at 8A and MAC210A8G at 10A versus the original 12A. Application circuits operating below these current levels are compatible.

Q: What is the significance of the on-state current difference?

A: On-state current rating determines the maximum RMS current the TRIAC can conduct continuously. Applications requiring sustained currents above 10A would not be suitable for either substitute. Applications operating at or below 8A are compatible with both parts.

Q: Are the TO-220-3 packages of all three parts mechanically identical?

A: All three parts use TO-220-3 package designation with through-hole mounting. Pin configuration and mechanical footprint are compatible for PCB layout purposes.

Q: What compliance certifications apply to the substitute parts?

A: Both 2N6344G and MAC210A8G carry ROHS3 compliance certification and are classified as REACH Unaffected. Both meet the regulatory requirements of the original TIC236M-S.

Q: Why is the TIC236M-S classified as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Bourns Inc. and is not available through standard distribution channels. Active alternatives from other manufacturers provide equivalent functionality for new designs and replacement applications.
