2STW200 Equivalent & Substitute Parts

Part Overview

The 2STW200 is a PNP Darlington bipolar junction transistor manufactured by STMicroelectronics, rated for 80 V collector-emitter breakdown voltage and 25 A maximum collector current in a TO-247-3 through-hole package. This component is classified as obsolete, necessitating identification of active equivalent parts for new designs and ongoing production requirements. The 2STW200 delivers 130 W maximum power dissipation and features a minimum DC current gain of 500 at 10 A collector current, making it suitable for high-current switching and amplification applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2STW200 is determined by electrical and mechanical compatibility across the following critical parameters:

Electrical Compatibility Criteria:

• Transistor polarity and configuration (PNP type)
• Maximum collector current rating (25 A minimum required)
• Collector-emitter breakdown voltage (80 V minimum required)
• Maximum power dissipation (130 W minimum required)
• Operating temperature range (150°C maximum junction temperature)

Mechanical Compatibility Criteria:

• Package type: TO-247-3 through-hole configuration
• Pin configuration and lead spacing

Regulatory Compliance:

• RoHS3 compliance
• REACH status alignment

The TIP36CW qualifies as a direct substitute based on matching collector current (25 A), identical package (TO-247-3), and superior electrical ratings that exceed the 2STW200 specifications. The TIP36CW provides higher collector-emitter breakdown voltage (100 V versus 80 V) and maintains through-hole mounting compatibility.

Parameter Comparison

Engineering Selection Recommendations

The TIP36CW is the manufacturer-recommended substitute for the obsolete 2STW200. Both components are manufactured by STMicroelectronics and maintain identical RoHS3 and REACH compliance status. The TIP36CW is currently in active production status, ensuring long-term availability and supply chain continuity.

The TIP36CW provides electrical performance that meets or exceeds the 2STW200 requirements: identical 25 A collector current rating, higher collector-emitter breakdown voltage (100 V versus 80 V), and compatible through-hole TO-247-3 packaging. Both devices operate at the same maximum junction temperature of 150°C.

For applications currently using the 2STW200, the TIP36CW substitution requires no circuit redesign. The higher voltage rating of the TIP36CW provides additional design margin in applications operating below 80 V.

Frequently Asked Questions (FAQ)

Q: Can the TIP36CW directly replace the 2STW200 in existing designs?

A: Yes. The TIP36CW is electrically and mechanically compatible with the 2STW200. Both devices share identical collector current ratings (25 A), the same TO-247-3 package, and compatible through-hole mounting. The TIP36CW's higher voltage rating (100 V versus 80 V) provides additional design margin.

Q: What is the primary difference between the 2STW200 and TIP36CW?

A: The 2STW200 is a Darlington configuration PNP transistor, while the TIP36CW is a standard PNP transistor. The TIP36CW provides higher collector-emitter breakdown voltage (100 V versus 80 V) and is in active production status, whereas the 2STW200 is obsolete.

Q: Are both parts available in the same package?

A: Yes. Both the 2STW200 and TIP36CW are supplied in TO-247-3 through-hole packages with identical pin configurations and lead spacing.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both the 2STW200 and TIP36CW are RoHS3 compliant and REACH unaffected, maintaining identical regulatory status.

Q: What is the maximum collector current for both devices?

A: Both the 2STW200 and TIP36CW are rated for a maximum collector current of 25 A.

Q: Can the TIP36CW be used in applications requiring the Darlington configuration of the 2STW200?

A: The TIP36CW is a standard PNP transistor, not a Darlington configuration. Applications requiring the specific Darlington characteristics of the 2STW200 must evaluate the TIP36CW's DC current gain and switching characteristics against circuit requirements.
