Substitute Part Grouping Explanation

Substitution eligibility for the DPG20C200PB is determined by the following critical parameters:

Mandatory Matching Parameters:

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

Current Rating Consideration: Substitute parts are grouped by average rectified current capacity. Parts rated at 10 A or higher provide direct functional equivalence. Parts rated below 10 A (3 A, 5 A, 8 A) are included as substitutes for applications where the full 10 A rating is not required, provided all other electrical and mechanical parameters align.

Technology Variants: Standard technology diodes and Super Barrier technology diodes are both included as substitutes, as both meet the fast recovery speed requirement and voltage/current specifications.

All substitute parts listed maintain RoHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification consistent with the main part.

Engineering Selection Recommendations

Direct Equivalents (10 A Rating, Active Status):

STTH1602CT and SBR20A200CT are the primary direct substitutes for the DPG20C200PB. Both maintain the 10 A current rating, 200 V reverse voltage, TO-220-3 package, and Active product status. STTH1602CT offers a lower forward voltage drop (1.1 V @ 8 A) and faster reverse recovery time (26 ns). SBR20A200CT, utilizing Super Barrier technology, provides the lowest forward voltage drop (0.86 V @ 10 A) among 10 A rated options.

Higher Current Capacity Alternatives (15 A Rating, Active Status):

STTH2002CT and STTH3002CT provide increased current capacity at 15 A while maintaining all other critical parameters. These parts are suitable for applications where additional current margin is beneficial. STTH3002CT offers the lowest forward voltage drop (1.05 V @ 15 A) and fastest reverse recovery time (22 ns) in this group.

Lower Current Capacity Alternatives (Active Status):

STTH1002CT (8 A), STTH602CT (3 A), and MUR620CTG (3 A) are suitable for applications requiring less than 10 A. These parts maintain the 200 V rating and TO-220-3 package. All are currently Active in product status.

Discontinued Part:

SBR10200CT (5 A rating) is listed as Discontinued at DiGi Electronics and should not be selected for new designs or long-term supply requirements.

Compliance Considerations:

All recommended substitute parts maintain RoHS3 compliance and REACH Unaffected status, consistent with the main part specification.

Frequently Asked Questions (FAQ)

Q: Can STTH1602CT be used as a direct replacement for DPG20C200PB?

A: Yes. STTH1602CT matches all critical parameters: 200 V reverse voltage, 10 A average rectified current per diode, 1 Pair Common Cathode configuration, TO-220-3 package, and fast recovery speed classification. The part is currently Active in product status.

Q: What is the difference between Standard and Super Barrier technology in these diode arrays?

A: Both technology types meet the fast recovery speed requirement (≤ 500ns, > 200mA). Super Barrier technology (SBR20A200CT) typically exhibits lower forward voltage drop and faster reverse recovery time compared to Standard technology at equivalent current ratings. Selection depends on application requirements for power dissipation and switching performance.

Q: Can I use STTH2002CT (15 A) in place of DPG20C200PB (10 A)?

A: Yes. STTH2002CT maintains all critical electrical and mechanical parameters while providing higher current capacity. This substitution is valid for applications where the 10 A rating is sufficient, as the higher rating provides additional design margin without compromising compatibility.

Q: Why is SBR10200CT not recommended?

A: SBR10200CT is listed as Discontinued at DiGi Electronics. For new designs and applications requiring long-term component availability, Active status parts such as STTH1602CT or SBR20A200CT should be selected instead.

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

A: Yes. All substitute parts listed are housed in TO-220-3 through-hole packages, ensuring mechanical and thermal compatibility with the DPG20C200PB footprint.

Q: What is the significance of reverse recovery time (trr) in selecting a substitute?

A: Reverse recovery time affects switching speed and switching losses. The DPG20C200PB specifies 35 ns. Substitute parts with lower trr values (such as STTH1602CT at 26 ns or SBR20A200CT at 30 ns) provide faster switching characteristics, which may reduce power dissipation in high-frequency applications.

Q: Can I use a 3 A rated part (STTH602CT or MUR620CTG) in an application designed for 10 A?

A: No. Current rating must match or exceed the application requirement. Using a 3 A part in a 10 A application will result in component failure or thermal damage. Select substitute parts with current ratings equal to or greater than the design requirement.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed maintain RoHS3 compliance and REACH Unaffected status, consistent with the DPG20C200PB specification.
