DSA70C200HB Equivalent & Substitute Parts

Part Overview

The DSA70C200HB is an active Schottky diode array manufactured by IXYS, configured as a 1 Pair Common Cathode arrangement rated for 200 V DC reverse voltage and 35 A average rectified current per diode. The device is packaged in a Through Hole TO-247-3 form factor and operates across a junction temperature range of -55°C to 175°C. This component is ROHS3 compliant and carries unlimited moisture sensitivity classification.

Equivalent and substitute parts are identified when alternative manufacturers offer diode arrays with matching electrical specifications, identical package configurations, and compatible operational parameters. Substitute components enable procurement flexibility, inventory management, and supply chain continuity while maintaining circuit performance and reliability.

Substitute Part Grouping Explanation

Substitution of the DSA70C200HB is determined by strict alignment of the following critical parameters:

Electrical Compatibility Criteria:

• Diode Configuration: 1 Pair Common Cathode (pin-for-pin compatibility)
• Technology: Schottky (fast recovery characteristics)
• Voltage - DC Reverse (Vr) (Max): 200 V (minimum voltage rating requirement)
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io) (switching performance)
• Operating Temperature - Junction: -55°C ~ 175°C (thermal operating range)

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole (PCB assembly method)
• Package / Case: TO-247-3 (physical form factor)
• Supplier Device Package: TO-247AD (standardized package designation)

Regulatory Compliance:

• RoHS Status: ROHS3 Compliant (environmental directive adherence)
• Moisture Sensitivity Level (MSL): 1 (Unlimited) (handling and storage requirements)

Substitute parts must satisfy all electrical and mechanical criteria. Variations in forward voltage (Vf), reverse leakage current (Ir), and average rectified current (Io) are acceptable within the bounds of circuit design margins, provided the substitute part meets or exceeds the minimum electrical performance requirements of the primary component.

Parameter Comparison

Engineering Selection Recommendations

The MBR90200WT manufactured by SMC Diode Solutions qualifies as a direct substitute for the DSA70C200HB based on matching electrical specifications, identical package configuration, and equivalent regulatory compliance status.

Substitution Basis:

Both components share identical voltage ratings (200 V DC reverse), matching diode configuration (1 Pair Common Cathode), identical Schottky technology, and equivalent fast recovery speed characteristics. The TO-247-3 package and TO-247AD supplier designation ensure mechanical and pin-level compatibility for direct PCB mounting replacement.

Both parts maintain ROHS3 compliance and unlimited moisture sensitivity classification (MSL 1), satisfying identical environmental and handling requirements. Operating temperature ranges are identical across both components (-55°C to 175°C junction temperature).

Parameter Variations:

The MBR90200WT exhibits a forward voltage of 960 mV at 45 A compared to the DSA70C200HB specification of 930 mV at 35 A. This represents a 30 mV increase in forward voltage drop at a higher current level. The reverse leakage current of the MBR90200WT is specified at 1 mA at 200 V, compared to 640 µA for the primary component, representing a 360 µA increase in leakage current.

Both components are active products with current inventory availability. Selection between these parts is determined by circuit design requirements regarding forward voltage drop tolerance and reverse leakage current specifications.

Frequently Asked Questions (FAQ)

Q: Can the MBR90200WT be used as a direct replacement for the DSA70C200HB in existing circuit designs?

A: Yes. Both components share identical voltage ratings (200 V), matching diode configuration (1 Pair Common Cathode), and identical TO-247-3 package specifications. Pin-level compatibility is maintained, enabling direct PCB mounting replacement without circuit board modifications.

Q: What are the key electrical differences between these two diode arrays?

A: The primary electrical differences are forward voltage and reverse leakage current. The MBR90200WT exhibits 960 mV forward voltage at 45 A versus 930 mV at 35 A for the DSA70C200HB. Reverse leakage current is 1 mA at 200 V for the MBR90200WT compared to 640 µA for the DSA70C200HB. Both components maintain identical fast recovery speed characteristics and operating temperature ranges.

Q: Are both components suitable for the same environmental and regulatory applications?

A: Yes. Both the DSA70C200HB and MBR90200WT are ROHS3 compliant and carry unlimited moisture sensitivity classification (MSL 1). Both operate across identical junction temperature ranges (-55°C to 175°C), satisfying equivalent environmental and handling requirements.

Q: What packaging format is used for both components?

A: Both components utilize Through Hole mounting in the TO-247-3 package configuration, designated as TO-247AD by the supplier. This standardized package enables direct mechanical and electrical compatibility for PCB assembly.

Q: How do the reverse leakage current specifications affect circuit performance?

A: Reverse leakage current represents the small current flowing through the diode when reverse biased. The MBR90200WT specification of 1 mA at 200 V is higher than the DSA70C200HB specification of 640 µA at 200 V. Circuit designs with stringent leakage current requirements must account for this 360 µA difference in component selection.

Q: Are both components currently available for procurement?

A: Yes. Both components are listed as active products with current inventory. The DSA70C200HB has 86,966 pieces in stock, and the MBR90200WT has 2,252 pieces in stock.
