S2012DTP SCR 200V 12A TO-252 Equivalent & Substitute Parts

Part Overview

The S2012DTP is a Standard Recovery SCR (Silicon Controlled Rectifier) rated for 200V off-state voltage and 12A RMS on-state current in a surface mount TO-252 (DPAK) package. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. Substitute parts maintain identical gate trigger characteristics, on-state voltage performance, and thermal operating range while offering higher voltage ratings or active product status.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the S2012DTP is determined by strict electrical and mechanical compatibility criteria:

Mandatory Matching Parameters:

• Gate trigger voltage (Vgt Max): 1.5V
• Gate trigger current (Igt Max): 20mA
• On-state voltage (Vtm Max): 1.6V
• On-state current (It RMS): 12A
• Hold current (Ih Max): 40mA
• Operating temperature range: -40°C to 125°C
• Package type: TO-252-3 DPAK surface mount
• SCR recovery type: Standard Recovery

Allowable Variation:

• Off-state voltage (Voff) may be equal to or greater than 200V. Higher voltage ratings provide backward compatibility in applications where the circuit voltage does not exceed the substitute part's rating.

The S4012DTP and S6012DTP are direct substitutes, differing only in off-state voltage ratings (400V and 600V respectively) while maintaining all other electrical and mechanical specifications identical to the S2012DTP.

Parameter Comparison

Engineering Selection Recommendations

S4012DTP (400V Rating): Use as a direct substitute when the application circuit voltage does not exceed 400V. This part is active in production status, ensuring long-term availability and supply chain continuity. RoHS3 compliance and MSL Level 1 rating match the original S2012DTP specifications.

S6012DTP (600V Rating): Use as a direct substitute when the application circuit voltage does not exceed 600V. This part is active in production status with identical compliance certifications. The higher voltage rating provides additional design margin in applications with voltage transients or future design modifications.

Both substitute parts maintain identical gate trigger characteristics, on-state performance, thermal operating range, and package configuration. Selection between S4012DTP and S6012DTP depends solely on the maximum voltage the application circuit will experience.

Frequently Asked Questions (FAQ)

Q: Can S4012DTP or S6012DTP be used in place of S2012DTP?

A: Yes. Both parts are direct substitutes. They maintain identical gate trigger voltage (1.5V max), gate trigger current (20mA max), on-state voltage (1.6V max), on-state current (12A RMS), hold current (40mA max), operating temperature range (-40°C to 125°C), and TO-252 DPAK package configuration. The only difference is off-state voltage rating: S4012DTP is rated 400V and S6012DTP is rated 600V, compared to the S2012DTP's 200V rating.

Q: What determines which substitute part to select?

A: Selection is based on the maximum off-state voltage the application circuit will experience. If the circuit voltage does not exceed 400V, either S4012DTP or S6012DTP may be used. If the circuit voltage does not exceed 600V, S6012DTP is suitable. The substitute part's voltage rating must equal or exceed the application's maximum circuit voltage.

Q: Are the substitute parts pin-compatible with S2012DTP?

A: Yes. All three parts use the TO-252-3 DPAK package with identical pinout and lead configuration, enabling direct PCB footprint compatibility without layout modifications.

Q: Do the substitute parts have the same compliance certifications?

A: Yes. S4012DTP and S6012DTP are both ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, matching the S2012DTP specifications. Both substitute parts also carry REACH Unaffected status.

Q: Why is S2012DTP listed as obsolete?

A: The S2012DTP is obsolete, meaning it is no longer in active production. S4012DTP and S6012DTP are active products from the same manufacturer with identical electrical and mechanical specifications except for voltage rating, providing production continuity and long-term supply availability.
