DSA30C150PB Equivalent & Substitute Parts

Part Overview

The DSA30C150PB is an IXYS Schottky diode array in a 1 Pair Common Cathode configuration rated for 150 V DC reverse voltage and 15 A average rectified current per diode. This component is classified as Active product status and is RoHS3 compliant. The part is mounted through-hole in a TO-220-3 package.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DSA30C150PB is determined by the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3

Current Rating Consideration: The DSA30C150PB is rated for 15 A average rectified current per diode. Substitute parts may have equal or higher current ratings while maintaining the same voltage and configuration specifications. Parts with lower current ratings are not suitable for direct substitution in applications requiring the full 15 A specification.

Forward Voltage Tolerance: Forward voltage drop varies among manufacturers and current levels. Substitute parts with forward voltage specifications within typical engineering tolerances are acceptable for equivalent operation.

Temperature Range: Operating temperature ranges may vary between manufacturers. The DSA30C150PB operates from -55°C to 175°C. Substitute parts with equal or wider temperature ranges are acceptable.

Compliance and Certifications: All substitute parts must maintain RoHS3 compliance and REACH unaffected status to ensure regulatory equivalence.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (15 A Rating):

The STPS30150CT from STMicroelectronics is the closest direct equivalent to the DSA30C150PB. Both parts share identical current ratings of 15 A, matching voltage specifications of 150 V, and identical diode configuration. The STPS30150CT maintains RoHS3 compliance and operates at a maximum junction temperature of 175°C, equivalent to the DSA30C150PB. This part is suitable for direct substitution in applications requiring the full 15 A specification.

Higher Current Capacity Alternative:

The MBR30150CT from Taiwan Semiconductor Corporation provides a 30 A current rating while maintaining the 150 V voltage specification and 1 Pair Common Cathode configuration. This part is suitable for applications where higher current capacity is beneficial or required. The MBR30150CT is RoHS3 compliant and maintains through-hole TO-220-3 mounting. The maximum junction temperature is 150°C, which is lower than the DSA30C150PB but remains within acceptable operating ranges for most applications.

Lower Current Alternatives:

The MBR10150CT-G1 (5 A), MBR20H150CTG (10 A), and V20150C-E3/4W (10 A) are suitable only for applications where the required current does not exceed their respective ratings. These parts maintain the 150 V voltage specification and TO-220-3 package configuration. Selection of lower-rated parts should be based on actual circuit current requirements.

Compliance Status:

All substitute parts listed maintain RoHS3 compliance and REACH unaffected status, ensuring regulatory equivalence with the DSA30C150PB.

Frequently Asked Questions (FAQ)

Q: Can the MBR30150CT (30 A) be used as a direct replacement for the DSA30C150PB (15 A)?

A: Yes. The MBR30150CT maintains the same 150 V voltage rating, 1 Pair Common Cathode configuration, and TO-220-3 package. The higher 30 A current rating does not prevent substitution; it provides additional current capacity. The part is RoHS3 compliant and suitable for direct substitution.

Q: What is the difference between the DSA30C150PB and STPS30150CT?

A: Both parts share identical 15 A current ratings and 150 V voltage specifications. The primary differences are manufacturer (IXYS versus STMicroelectronics) and forward voltage characteristics (890 mV versus 920 mV at 15 A). Both are RoHS3 compliant and operate in the TO-220-3 package. The STPS30150CT exhibits lower reverse leakage current (6.5 µA versus 500 µA at 150 V).

Q: Can lower-rated parts like the MBR10150CT-G1 (5 A) substitute for the DSA30C150PB (15 A)?

A: Lower-rated parts are not suitable for direct substitution in applications requiring the full 15 A specification. The MBR10150CT-G1 is limited to 5 A operation and will not safely handle 15 A current. Selection of substitute parts must match or exceed the required current rating for the application.

Q: Are all substitute parts available in the same TO-220-3 package?

A: All listed substitute parts use the TO-220-3 through-hole package configuration, ensuring mechanical and thermal compatibility with the DSA30C150PB. Supplier device package designations may vary (TO-220AB, TO-220) but refer to the same physical TO-220-3 form factor.

Q: What is the significance of the 150 V voltage rating in substitution?

A: The 150 V DC reverse voltage rating is a critical parameter for substitution. All listed substitute parts maintain this 150 V specification. Parts with lower voltage ratings are not suitable for applications requiring 150 V operation. Parts with higher voltage ratings are acceptable but may have different forward voltage characteristics.

Q: How does operating temperature range affect part selection?

A: The DSA30C150PB operates from -55°C to 175°C. Some substitute parts have narrower temperature ranges (MBR30150CT: -55°C to 150°C; MBR20H150CTG: -20°C to 150°C). Selection should ensure the substitute part's temperature range encompasses the application's operating environment. Narrower ranges are acceptable if the application operates within those limits.

Q: What does "1 Pair Common Cathode" configuration mean for substitution?

A: This configuration indicates the diode array contains two diodes sharing a common cathode connection. All substitute parts maintain this identical configuration, ensuring pin compatibility and functional equivalence in circuits designed for the DSA30C150PB.

Q: Are there differences in reverse leakage current among the substitute parts?

A: Yes. Reverse leakage current varies: DSA30C150PB (500 µA), MBR30150CT (100 µA), MBR10150CT-G1 (50 µA), MBR20H150CTG (50 µA), STPS30150CT (6.5 µA), and V20150C-E3/4W (150 µA) at 150 V. Lower leakage current may be beneficial in low-power applications but does not prevent substitution in standard applications.

Q: Do all substitute parts meet the same compliance standards as the DSA30C150PB?

A: Yes. All listed substitute parts are RoHS3 compliant and REACH unaffected, matching the regulatory status of the DSA30C150PB. Moisture Sensitivity Level (MSL) is 1 (Unlimited) for all parts except MBR20H150CTG (Not Applicable), indicating equivalent handling requirements.
