Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPG30C400PB are qualified based on the following criteria:

Mandatory Matching Parameters:

• Diode Configuration: 1 Pair Common Cathode
• Voltage - DC Reverse (Vr) (Max): 400 V
• Mounting Type: Through Hole
• Package / Case: TO-220-3
• Technology: Standard
• Speed Classification: Fast Recovery ≤ 500ns, > 200mA (Io)
• RoHS Status: ROHS3 Compliant
• Product Status: Active

Variable Parameters Permitting Substitution:

• Current - Average Rectified (Io) (per Diode): Substitute parts rated at 8 A or 4 A are acceptable for applications requiring reduced current capacity
• Voltage - Forward (Vf) (Max) @ If: Forward voltage varies with current rating; substitutes exhibit different Vf characteristics
• Reverse Recovery Time (trr): Substitute parts range from 28 ns to 60 ns, all within fast recovery classification
• Current - Reverse Leakage @ Vr: Substitute parts rated at 10 µA remain within acceptable leakage parameters
• Operating Temperature - Junction: Substitute parts maintain -40°C to -65°C minimum operating temperature, compatible with DPG30C400PB applications

Three substitute parts are identified: MUR1640CTG (8 A, onsemi), MURH840CTG (4 A, onsemi), and STTH16R04CT (8 A, STMicroelectronics).

Parameter Comparison

Engineering Selection Recommendations

DPG30C400PB (Primary Part): Select this part for applications requiring 15 A average rectified current per diode at 400 V reverse voltage. The device offers the lowest forward voltage drop (1.39 V @ 15 A) and moderate reverse recovery time (45 ns). ROHS3 compliance and active product status support long-term availability. Current inventory of 1043 pieces supports immediate procurement.

MUR1640CTG (onsemi, 8 A Substitute): This part is suitable for applications with maximum current requirements of 8 A per diode. Forward voltage is 1.3 V @ 8 A, slightly lower than the primary part at equivalent current levels. Reverse recovery time of 60 ns remains within fast recovery classification. Extended minimum operating temperature (-65°C) provides broader thermal range. Inventory of 53800 pieces ensures availability. ROHS3 compliance maintained.

MURH840CTG (onsemi, 4 A Substitute): This part is suitable for applications with maximum current requirements of 4 A per diode. Forward voltage is 2.2 V @ 4 A, representing higher dissipation at reduced current. Reverse recovery time of 28 ns is the fastest among all options. Extended minimum operating temperature (-65°C) provides broader thermal range. Inventory of 1325 pieces supports procurement. ROHS3 compliance maintained.

STTH16R04CT (STMicroelectronics, 8 A Substitute): This part is suitable for applications with maximum current requirements of 8 A per diode. Forward voltage is 1.5 V @ 8 A. Reverse recovery time of 50 ns is intermediate among options. Minimum operating temperature of -40°C is narrower than other substitutes but compatible with most industrial applications. Inventory of 1407 pieces supports procurement. ROHS3 compliance and MSL 1 rating maintained.

All substitute parts maintain identical voltage classification, diode configuration, and through-hole TO-220-3 package form factor. Selection between substitutes depends on application current requirements and thermal operating range constraints.

Frequently Asked Questions (FAQ)

Q: Can MUR1640CTG replace DPG30C400PB in all applications?

A: MUR1640CTG is a direct substitute only for applications where the maximum required current per diode does not exceed 8 A. The 400 V reverse voltage rating, TO-220-3 package, and fast recovery speed classification are identical. Forward voltage characteristics differ due to the lower current rating. Applications requiring the full 15 A capacity of the DPG30C400PB cannot use this substitute.

Q: What is the primary difference between MUR1640CTG and STTH16R04CT?

A: Both parts are rated for 8 A average rectified current and 400 V reverse voltage in TO-220-3 packages. MUR1640CTG (onsemi) has a forward voltage of 1.3 V @ 8 A and reverse recovery time of 60 ns. STTH16R04CT (STMicroelectronics) has a forward voltage of 1.5 V @ 8 A and reverse recovery time of 50 ns. MUR1640CTG offers lower forward voltage drop, while STTH16R04CT provides faster reverse recovery. Operating temperature ranges differ: MUR1640CTG operates from -65°C to 175°C, while STTH16R04CT operates from -40°C to 175°C.

Q: Is MURH840CTG suitable for high-current applications?

A: No. MURH840CTG is rated for 4 A average rectified current per diode, making it unsuitable for applications requiring 8 A or 15 A operation. This part is appropriate only for low-current rectification circuits operating at 400 V reverse voltage. The forward voltage of 2.2 V @ 4 A indicates higher power dissipation at its rated current compared to higher-current-rated alternatives.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. DPG30C400PB, MUR1640CTG, MURH840CTG, and STTH16R04CT are all ROHS3 compliant. All parts are REACH unaffected and classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: What is the significance of reverse recovery time differences?

A: Reverse recovery time (trr) indicates the speed at which the diode transitions from forward conduction to reverse blocking. DPG30C400PB has trr of 45 ns, MUR1640CTG has 60 ns, MURH840CTG has 28 ns, and STTH16R04CT has 50 ns. All values fall within the fast recovery classification (≤ 500 ns, > 200 mA). Faster recovery times reduce switching losses in high-frequency applications. MURH840CTG offers the fastest recovery, while MUR1640CTG offers the slowest among substitutes.

Q: Can these parts be used interchangeably in the same circuit board layout?

A: Yes, regarding physical compatibility. All parts use identical TO-220-3 through-hole package and mounting type, permitting direct board-level substitution without layout modification. However, electrical performance differs due to current rating and forward voltage variations. Circuit design must account for these differences, particularly in thermal management and voltage drop calculations.

Q: What inventory considerations apply to part selection?

A: DPG30C400PB has 1043 pieces in stock. MUR1640CTG has the highest inventory at 53800 pieces, supporting high-volume procurement. STTH16R04CT has 1407 pieces, and MURH840CTG has 1325 pieces. Inventory levels may influence lead time and cost considerations for procurement planning.
