2STN2360 Equivalent & Substitute Parts

Part Overview

The 2STN2360 is a PNP bipolar junction transistor manufactured by STMicroelectronics, rated for 60 V collector-emitter breakdown voltage and 3 A maximum collector current. The device is housed in a SOT-223 surface mount package and is designed for general-purpose switching and amplification applications. The 2STN2360 is classified as obsolete, necessitating identification of active equivalent and substitute components that maintain functional compatibility within specified electrical and mechanical parameters.

Current - Collector (Ic) (Max): 3 A minimum
Package / Case: TO-261-4 or TO-261AA (SOT-223 footprint)
Mounting Type: Surface Mount
RoHS Status: ROHS3 Compliant
Moisture Sensitivity Level: 1 (Unlimited)

Secondary Parameters (Application-Dependent):

Frequency - Transition: 130 MHz or greater
Operating Temperature: 150°C maximum junction temperature
Vce Saturation characteristics
DC Current Gain (hFE)

Substitute parts are grouped into three categories based on current rating alignment:

Category 1: Direct Current Rating Match (3 A) Parts with 3 A maximum collector current provide direct functional equivalence for applications designed around the 2STN2360 specifications.

Category 2: Higher Current Rating (5 A, 6 A) Parts with current ratings exceeding 3 A are suitable for applications where the 2STN2360 operates below its maximum current specification, providing design margin and thermal headroom.

Category 3: Lower Current Rating (1 A, 2 A) Parts with current ratings below 3 A are suitable only for applications where the circuit operates at reduced current levels, not for designs requiring the full 3 A capability.

Engineering Selection Recommendations

Primary Substitutes (Direct Equivalence):

The following parts provide direct functional equivalence to the 2STN2360 with matching 3 A collector current rating and 60 V breakdown voltage:

FZT751QTA: Active status, 3 A / 60 V, 140 MHz transition frequency, 3 W power rating, ROHS3 compliant
FZT751QTC: Active status, 3 A / 60 V, 140 MHz transition frequency, automotive grade (AEC-Q101), ROHS3 compliant
FZT751TA: Active status, 3 A / 60 V, 140 MHz transition frequency, 2 W power rating, ROHS3 compliant
FZT751TC: Active status, 3 A / 60 V, 140 MHz transition frequency, 2 W power rating, ROHS3 compliant

All primary substitutes are manufactured by Diodes Incorporated, maintain SOT-223 packaging, and are classified as active products with full ROHS3 compliance and MSL 1 rating.

Secondary Substitutes (Higher Current Capability):

The following parts exceed the 3 A specification and are suitable for applications where the 2STN2360 operates below maximum current:

FZT951TA: Active status, 5 A / 60 V, 120 MHz transition frequency, 3 W power rating, ROHS3 compliant
FZT951TC: Active status, 5 A / 60 V, 120 MHz transition frequency, 3 W power rating, ROHS3 compliant
DSS60600MZ4-13: Active status, 6 A / 60 V, 100 MHz transition frequency, 1.2 W power rating, ROHS3 compliant

Conditional Substitutes (Lower Current Capability):

The following parts are rated below 3 A and are suitable only for applications operating at reduced current levels:

BCP52TA: Active status, 1 A / 60 V, 125 MHz transition frequency, 2 W power rating, ROHS3 compliant
FZT591TA: Active status, 1 A / 60 V, 150 MHz transition frequency, 2 W power rating, ROHS3 compliant

Voltage-Elevated Substitute:

FZT792ATA: Active status, 2 A / 70 V, 160 MHz transition frequency, 2 W power rating, ROHS3 compliant. This part exceeds the 60 V specification and is suitable for applications requiring higher voltage margin.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and SOT-223 surface mount packaging compatible with the original 2STN2360 footprint.

Frequently Asked Questions (FAQ)

Q: Can FZT751TA directly replace 2STN2360 in all applications?

A: FZT751TA is electrically compatible with 2STN2360 for applications operating within the specified 3 A / 60 V envelope. Both devices share identical maximum ratings for collector current and breakdown voltage, operate at 150°C maximum junction temperature, and are housed in SOT-223 packages. Pinout compatibility must be verified for the specific circuit board layout.

Q: What is the difference between FZT751QTC and FZT751TA?

A: FZT751QTC is qualified to automotive standard AEC-Q101 and is supplied in Tape & Reel packaging, while FZT751TA is supplied in Cut Tape & Digi-Reel packaging. Both devices have identical electrical specifications: 3 A / 60 V, 140 MHz transition frequency, and 2 W power rating. Selection depends on packaging requirements and automotive qualification necessity.

Q: Can I use FZT951TA (5 A) instead of 2STN2360 (3 A)?

A: FZT951TA is electrically compatible and provides higher current capability (5 A versus 3 A). This substitution is valid for applications where the circuit operates at or below 3 A. The higher current rating provides additional design margin and thermal headroom. Verify that the circuit design does not depend on the specific current-limiting characteristics of the 2STN2360.

Q: Why should I avoid BCP52TA as a substitute?

A: BCP52TA is rated for only 1 A maximum collector current, which is below the 2STN2360 specification of 3 A. This part is suitable only for applications confirmed to operate at 1 A or below. Using BCP52TA in a circuit designed for 3 A operation will result in device failure or thermal damage.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental compliance profile of the 2STN2360.

Q: What is the significance of the SOT-223-3 package designation?

A: SOT-223-3 is the supplier device package designation for Diodes Incorporated parts and is functionally equivalent to the SOT-223 package used by STMicroelectronics for the 2STN2360. Both designations refer to the same physical TO-261-4 or TO-261AA case outline with three leads. PCB footprints are compatible.

Q: Can I use FZT792ATA (70 V) in place of 2STN2360 (60 V)?

A: FZT792ATA exceeds the 60 V breakdown voltage specification with a 70 V rating. This substitution is valid for applications where the circuit operates at 60 V or below. The higher voltage rating provides additional safety margin. However, FZT792ATA is rated for 2 A maximum collector current, which is below the 3 A specification of the 2STN2360. This part is suitable only for applications confirmed to operate at 2 A or below.

Q: What is the difference between Cut Tape (CT) and Tape & Reel (TR) packaging?

A: Cut Tape and Tape & Reel are supply formats, not electrical specifications. Cut Tape is supplied in individual strips for manual handling or small-volume assembly. Tape & Reel is supplied on continuous reels for automated pick-and-place equipment. Electrical performance is identical; selection depends on assembly process requirements.

Q: Is the transition frequency difference between 2STN2360 (130 MHz) and FZT751TA (140 MHz) significant?

A: The transition frequency difference is within normal manufacturing variation for PNP transistors in this class. FZT751TA's 140 MHz specification exceeds the 2STN2360's 130 MHz, indicating equal or superior high-frequency performance. This substitution is valid for all applications where the 2STN2360 was specified.
