TMA36S-L TRIAC 600V 3A Equivalent & Substitute Parts

Part Overview

The TMA36S-L is a standard TRIAC manufactured by Sanken Electric USA Inc., rated for 600V off-state voltage and 3A on-state current in a TO-220F package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity. Substitute parts must maintain electrical compatibility across voltage, current, and gate trigger specifications while accommodating packaging and thermal requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the TMA36S-L is determined by the following critical parameters:

Voltage - Off State: Must be 600V or higher
Current - On State (It (RMS)): Must be equal to or greater than 3A
Voltage - Gate Trigger (Vgt): Must be 1.5V or lower for direct gate drive compatibility
Current - Gate Trigger (Igt): Must be 20mA or lower for standard gate drive circuits
Mounting Type: Through Hole required
Package / Case: TO-220-3 configuration required

All substitute parts listed meet these criteria and are classified as active products with current manufacturing status and RoHS compliance.

Engineering Selection Recommendations

BTA204X-600F,127 (WeEn Semiconductors): This part meets all minimum electrical requirements with 4A on-state current and 1.5V gate trigger voltage matching the original specification. Operating temperature is limited to 125°C maximum, which may restrict applications requiring the full -40°C lower temperature range. RoHS compliant and actively manufactured.

Q6006L5TP (Littelfuse Inc.): This part exceeds electrical requirements with 6A on-state current and higher surge capability. Gate trigger voltage of 2.5V and gate trigger current of 50mA exceed the original specification, requiring verification of gate drive circuit compatibility. Offers the widest operating temperature range (-40°C to 125°C) and highest surge rating. ROHS3 compliant and actively manufactured.

T435T-600FP (STMicroelectronics): This Alternistor-type TRIAC provides the lowest gate trigger voltage (1.3V) and matches surge specifications. The snubberless design may provide improved performance in certain applications. Operating temperature range matches the original (-40°C to 125°C). ROHS3 compliant and actively manufactured.

Frequently Asked Questions (FAQ)

Q: Can BTA204X-600F,127 be used as a direct replacement for TMA36S-L?

A: BTA204X-600F,127 meets all critical electrical parameters and is pin-compatible in TO-220F packaging. The primary consideration is the reduced operating temperature range (125°C maximum vs. -40°C to 125°C). Verify application temperature requirements before selection.

Q: Why does Q6006L5TP have higher gate trigger specifications?

A: Q6006L5TP is rated for 6A on-state current with correspondingly higher gate trigger voltage (2.5V) and current (50mA). Gate drive circuits designed for 1.5V/20mA must be evaluated for compatibility with these higher values.

Q: What is the difference between standard TRIAC and Alternistor types?

A: T435T-600FP is classified as an Alternistor-type TRIAC with snubberless design. This topology may reduce EMI and improve switching characteristics in specific applications. Electrical substitution is valid, but application-specific performance testing may be warranted.

Q: Are all substitute parts RoHS compliant?

A: Yes. BTA204X-600F,127 is RoHS Compliant. Q6006L5TP and T435T-600FP are ROHS3 Compliant, meeting current regulatory requirements.

Q: Can I use a higher current-rated TRIAC in place of the 3A TMA36S-L?

A: Yes. Higher current ratings (4A or 6A) are electrically compatible for applications requiring 3A or less. Verify that gate drive circuits can supply the required gate trigger current for the selected substitute part.

Q: What packaging considerations apply to these substitutes?

A: All parts use TO-220-3 through-hole mounting. BTA204X-600F,127 and Q6006L5TP offer isolated tab options, which may be beneficial for thermal management or isolation requirements in specific circuit designs.
