Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DSB60C30PB are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for substitution eligibility:

Fixed Parameters (Must Match Exactly):

• Diode Configuration: 1 Pair Common Cathode
• Technology: Schottky
• Voltage - DC Reverse (Vr) (Max): 30 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3
• Speed: Fast Recovery ≤ 500ns, > 200mA (Io)

Variable Parameters (Allowed Variation):

• Current - Average Rectified (Io) (per Diode): Substitutes may operate at lower current ratings
• Voltage - Forward (Vf) (Max) @ If: Variation permitted within same voltage class
• Current - Reverse Leakage @ Vr: Variation permitted
• Operating Temperature - Junction: Extended or equivalent ranges acceptable
• Product Status: Active or Last Time Buy acceptable

The identified substitute parts MBR2030CTLG and MBR30H30CTG satisfy all fixed parameters while offering alternative current ratings of 10 A and 15 A respectively, compared to the primary part's 30 A rating.

Parameter Comparison

Engineering Selection Recommendations

DSB60C30PB (Primary Part): The DSB60C30PB is the recommended selection for new designs requiring 30 A per diode capacity. The part maintains Active product status with established supply availability (1113 pieces in stock). ROHS3 compliance and MSL Level 1 (Unlimited) classification support standard manufacturing and storage conditions without moisture sensitivity constraints.

MBR30H30CTG (Preferred Substitute): The MBR30H30CTG is the preferred substitute when current requirements do not exceed 15 A per diode. This part maintains Active product status, identical operating temperature range (-55 to 150 °C), and ROHS3 compliance. The TO-220-3 package and Through Hole mounting provide direct mechanical compatibility. Forward voltage characteristics (480 mV @ 15 A) are favorable for efficiency-sensitive applications. Inventory availability is strong (2438 pieces in stock).

MBR2030CTLG (Secondary Substitute): The MBR2030CTLG is applicable only for applications with maximum current requirements of 10 A per diode. This part carries Last Time Buy product status, indicating limited future availability. Extended operating temperature range (-65 to 175 °C) provides thermal margin beyond the primary part. ROHS3 compliance is maintained. Selection of this part should account for supply continuity constraints.

Frequently Asked Questions (FAQ)

Q: Can MBR2030CTLG or MBR30H30CTG directly replace DSB60C30PB in existing designs?

A: Direct replacement is possible only when circuit current requirements do not exceed the substitute part's rated capacity. MBR30H30CTG supports up to 15 A per diode; MBR2030CTLG supports up to 10 A per diode. If the application requires the full 30 A capacity of DSB60C30PB, substitution is not permissible. All three parts share identical TO-220-3 package geometry and pin configuration, enabling mechanical interchangeability when electrical requirements align.

Q: What are the key electrical differences between these parts?

A: All three parts maintain 30 V DC reverse voltage rating and Schottky technology. Primary differences are current capacity (30 A, 15 A, or 10 A per diode) and forward voltage characteristics. DSB60C30PB exhibits 550 mV forward voltage at 30 A; MBR30H30CTG exhibits 480 mV at 15 A; MBR2030CTLG exhibits 520 mV at 10 A. Reverse leakage current varies: DSB60C30PB at 20 µA, MBR30H30CTG at 800 µA, and MBR2030CTLG at 5 mA, all measured at 30 V.

Q: Are there temperature operating range differences?

A: DSB60C30PB and MBR30H30CTG share identical junction temperature range (-55 to 150 °C). MBR2030CTLG extends the upper limit to 175 °C and lower limit to -65 °C, providing broader thermal operation. Selection should account for specific application thermal requirements.

Q: What is the significance of Last Time Buy status for MBR2030CTLG?

A: Last Time Buy status indicates that onsemi has announced end-of-life for this part number. While current inventory is available (1647 pieces), future procurement may become unavailable. For new designs or long-term production requirements, MBR30H30CTG (Active status) or DSB60C30PB (Active status) are preferred to ensure supply continuity.

Q: Are all three parts RoHS3 compliant?

A: Yes. DSB60C30PB, MBR2030CTLG, and MBR30H30CTG are all ROHS3 Compliant. All parts are REACH Unaffected and classified under ECCN EAR99 for export control purposes.

Q: What is the moisture sensitivity classification difference?

A: DSB60C30PB carries MSL Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. MBR2030CTLG and MBR30H30CTG are classified as Not Applicable for MSL, reflecting their robust packaging characteristics. All parts are suitable for standard manufacturing environments without special moisture control requirements.
