2SD15110RL Equivalent & Substitute Parts

Part Overview

The 2SD15110RL is an NPN Darlington bipolar junction transistor manufactured by Panasonic Electronic Components, designed for surface mount applications in the MiniP3-F1 package. This device is rated for 80 V collector-emitter breakdown voltage and 1 A maximum collector current, with a maximum power dissipation of 1 W and transition frequency of 150 MHz. The product status is obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 2SD15110RL is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Transistor Type: NPN - Darlington configuration
• Voltage - Collector Emitter Breakdown (Max): 80 V minimum
• Current - Collector (Ic) (Max): 1 A or greater
• Power - Max: 1 W or greater
• Operating Temperature: 150°C or higher maximum junction temperature

Mechanical Compatibility Criteria:

• Mounting Type: Surface Mount
• Package / Case: TO-243AA
• Moisture Sensitivity Level (MSL): 1 (Unlimited)

The substitute parts BST52,115, BST52,135, and BST52TA meet the core electrical requirements of 80 V breakdown voltage and NPN Darlington configuration. All substitute parts are surface mount devices in TO-243AA packages with MSL rating of 1. Variations in transition frequency, DC current gain, and maximum collector current are secondary parameters that do not prevent functional substitution when the primary electrical and mechanical criteria are satisfied.

Parameter Comparison

Engineering Selection Recommendations

BST52,115 and BST52,135 (Nexperia USA Inc.): Both parts are active products with ROHS3 compliance and AEC-Q101 automotive qualification. These devices provide enhanced electrical performance with 200 MHz transition frequency and 1.3 W maximum power dissipation compared to the 2SD15110RL. The 1 A maximum collector current matches the original specification. These parts are suitable for applications requiring automotive-grade reliability and environmental compliance.

BST52TA (Diodes Incorporated): This part is an active product with ROHS3 compliance and extended operating temperature range (−55°C to 150°C). The maximum collector current is rated at 500 mA, which is lower than the 2SD15110RL specification of 1 A. The BST52TA is suitable for applications where the collector current requirement does not exceed 500 mA and extended low-temperature operation is required.

All substitute parts maintain the critical 80 V breakdown voltage and NPN Darlington configuration required for functional equivalence. Selection among the three substitutes depends on specific application requirements regarding maximum collector current, temperature range, and compliance certifications.

Frequently Asked Questions (FAQ)

Q: Can BST52TA be used as a direct replacement for 2SD15110RL in all applications?

A: The BST52TA is functionally equivalent for applications where the maximum collector current does not exceed 500 mA. The 2SD15110RL is rated for 1 A maximum collector current, while BST52TA is rated for 500 mA. Applications requiring the full 1 A capability must use BST52,115 or BST52,135.

Q: What is the difference between BST52,115 and BST52,135?

A: Both parts are manufactured by Nexperia USA Inc. and share identical electrical specifications: 80 V breakdown voltage, 1 A maximum collector current, 200 MHz transition frequency, and 1.3 W maximum power dissipation. The primary difference is the maximum collector cutoff current (ICBO): BST52,115 is rated at 50 nA while BST52,135 is rated at 500 nA. Both parts are AEC-Q101 qualified and ROHS3 compliant.

Q: Are all substitute parts available in the same package as the 2SD15110RL?

A: All substitute parts use the TO-243AA package case, which is mechanically compatible with the 2SD15110RL. However, the supplier device packages differ: the 2SD15110RL uses MiniP3-F1, while BST52,115 and BST52,135 use SOT-89, and BST52TA uses SOT-89-3. These designations refer to the same physical TO-243AA package with different lead configurations or tape & reel specifications.

Q: Do the substitute parts meet environmental compliance requirements?

A: BST52,115, BST52,135, and BST52TA are all ROHS3 compliant and have MSL rating of 1 (Unlimited). BST52,115 and BST52,135 carry AEC-Q101 automotive qualification. All parts are REACH unaffected or compliant, meeting current environmental standards.

Q: What is the impact of the higher transition frequency in the substitute parts?

A: BST52,115 and BST52,135 have a transition frequency of 200 MHz compared to the 2SD15110RL at 150 MHz. Higher transition frequency indicates faster switching capability and improved high-frequency performance. This enhancement does not prevent substitution and may provide improved performance in switching applications.

Q: Can the 2SD15110RL be used in new designs?

A: The 2SD15110RL is classified as obsolete. New designs should use active substitute parts: BST52,115, BST52,135, or BST52TA, depending on specific application requirements for collector current rating and operating temperature range.
