Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSA30C150HB are identified based on strict equivalence of the following critical parameters:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 150 V
• Current - Average Rectified (Io) (per Diode): 15 A
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)
• Mounting Type: Through Hole
• Package / Case: TO-247-3
• Product Status: Active
• RoHS Status: ROHS3 Compliant

Allowable Parameter Variations: Substitute parts may exhibit differences in forward voltage (Vf) and reverse leakage current (Ir) within the design specifications of the respective manufacturers, provided all mandatory parameters remain identical. Operating temperature range may vary at the maximum junction temperature specification. These variations remain within acceptable engineering tolerances for direct substitution in circuit applications.

Parameter Comparison

Engineering Selection Recommendations

Both the DSA30C150HB and STPS30150CW are active products with identical RoHS3 compliance and unlimited moisture sensitivity level (MSL 1), confirming suitability for direct substitution in production environments. The parts share identical electrical ratings for reverse voltage (150 V), average rectified current (15 A per diode), and fast recovery speed characteristics (≤ 500ns, > 200mA).

The STPS30150CW exhibits a forward voltage of 920 mV at 15 A compared to 880 mV for the DSA30C150HB, representing a 40 mV difference. The STPS30150CW also demonstrates significantly lower reverse leakage current at 6.5 µA versus 250 µA for the DSA30C150HB at 150 V. These parameter variations fall within the design specifications of each manufacturer and do not affect functional equivalence for applications requiring 150 V, 15 A Schottky diode arrays in TO-247-3 Through Hole packaging.

Selection between these parts is determined by inventory availability, lead time requirements, and application-specific thermal or leakage current constraints. Both parts are suitable for direct pin-compatible replacement without circuit modification.

Frequently Asked Questions (FAQ)

Q: Can the STPS30150CW replace the DSA30C150HB in existing designs?

A: Yes. Both parts are Schottky diode arrays with 1 Pair Common Cathode configuration, 150 V reverse voltage rating, 15 A average rectified current per diode, and identical TO-247-3 Through Hole packaging. Pin compatibility and electrical ratings are equivalent for direct substitution.

Q: What is the significance of the forward voltage difference between these parts?

A: The DSA30C150HB specifies 880 mV maximum forward voltage at 15 A, while the STPS30150CW specifies 920 mV at the same current. This 40 mV difference reflects manufacturer-specific design characteristics and remains within acceptable operating parameters for Schottky diode arrays. Circuit designs accommodating standard Schottky forward voltage tolerances will function with either part.

Q: Why does the STPS30150CW have lower reverse leakage current?

A: Reverse leakage current (Ir) is a manufacturer-specific parameter influenced by semiconductor process technology and device design. The STPS30150CW exhibits 6.5 µA at 150 V compared to 250 µA for the DSA30C150HB. Both values are within acceptable specifications for Schottky diode arrays and do not indicate a functional difference in substitution capability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the DSA30C150HB and STPS30150CW are RoHS3 compliant with unlimited moisture sensitivity level (MSL 1), confirming suitability for regulated manufacturing environments and long-term storage without special handling requirements.

Q: What is the operating temperature range for these parts?

A: Both parts are rated for a maximum junction temperature of 175°C. The DSA30C150HB specifies a minimum junction temperature of -55°C, establishing an operating range of -55°C to 175°C. The STPS30150CW specifies 175°C as the maximum junction temperature. Both parts are suitable for industrial temperature applications.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use identical TO-247-3 Through Hole packaging with the same pinout configuration for 1 Pair Common Cathode diode arrays. No circuit board modifications or component repositioning is required for substitution.

Q: What is the product status of these parts?

A: Both the DSA30C150HB and STPS30150CW are active products with ongoing manufacturing and availability. Active product status confirms long-term supply chain support and suitability for new design implementations and production volume requirements.
