DPG30C200PB Equivalent & Substitute Parts

Part Overview

The DPG30C200PB is a diode array manufactured by IXYS in the HiPerFRED™ series, configured as a 1 Pair Common Cathode rectifier with 200 V reverse voltage rating and 15 A average rectified current per diode. The device is packaged in TO-220-3 through-hole format and is currently active in production with 2400 pieces in stock.

Substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers are preferred for supply chain diversification, or when design requirements allow for compatible alternatives with different electrical characteristics within acceptable operating parameters.

Substitute Part Grouping Explanation

Substitution eligibility for the DPG30C200PB 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 Compatibility: Substitute parts are grouped by average rectified current capacity. The DPG30C200PB operates at 15 A per diode. Substitutes with equal or greater current ratings (10 A, 15 A) are direct replacements. Substitutes with lower current ratings (3 A, 5 A, 8 A) are suitable only when circuit design permits reduced current capacity.

Technology Variants: Standard technology diodes (IXYS HiPerFRED™, STMicroelectronics) and Super Barrier technology diodes (Diodes Incorporated SBR® series) both meet the fast recovery speed requirement and are electrically compatible within the specified voltage and current parameters.

Compliance and Certification: All substitute parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory equivalence.

Engineering Selection Recommendations

Direct Equivalents (Equal Current Rating - 15 A):

STTH2002CT and STTH3002CT from STMicroelectronics are direct functional equivalents to the DPG30C200PB. Both devices maintain the 200 V reverse voltage rating, 15 A current capacity, TO-220-3 package, and fast recovery speed classification. Both are active products with ROHS3 compliance. STTH3002CT offers improved forward voltage characteristics (1.05 V @ 15 A versus 1.26 V @ 15 A) and faster reverse recovery time (22 ns versus 35 ns), resulting in lower power dissipation and improved switching performance.

Higher Current Capacity Alternatives (10 A Rating):

STTH1602CT (STMicroelectronics) and SBR20A200CT (Diodes Incorporated) are rated for 10 A per diode. These devices are suitable for applications where the DPG30C200PB is unavailable and the circuit design permits operation at the lower current rating. Both maintain 200 V reverse voltage, TO-220-3 package, and fast recovery characteristics. Both are active products with full compliance certifications.

Lower Current Capacity Alternatives (5 A and 3 A Ratings):

SBR10U200CT (5 A), STTH1002CT (8 A), and STTH602CT (3 A) are suitable only when circuit requirements allow reduced current capacity. These devices maintain voltage and package compatibility but are limited to lower current applications.

Discontinued Product Consideration:

SBR10200CT is discontinued at DiGi Electronics and should not be selected for new designs despite technical compatibility. Active alternatives with equivalent or superior specifications are available.

Compliance and Supply Chain:

All recommended active substitutes maintain ROHS3 compliance and REACH unaffected status. STMicroelectronics devices show higher inventory availability (16,926 to 44,200 pieces), while Diodes Incorporated SBR® series devices provide alternative technology with lower forward voltage characteristics.

Frequently Asked Questions (FAQ)

Q: Can STTH2002CT directly replace DPG30C200PB in existing designs?

A: Yes. STTH2002CT matches all critical parameters: 200 V reverse voltage, 15 A current rating, 1 Pair Common Cathode configuration, TO-220-3 package, and fast recovery speed classification. Both devices are active products with ROHS3 compliance. No circuit modifications are required.

Q: What is the difference between Standard technology (IXYS, STMicroelectronics) and Super Barrier technology (Diodes Incorporated SBR®)?

A: Both technology types meet the fast recovery speed requirement and 200 V voltage rating. Super Barrier technology typically exhibits lower forward voltage drop (0.82-0.90 V versus 1.05-1.26 V), resulting in reduced power dissipation. Selection depends on application requirements for efficiency versus cost considerations.

Q: Can I use STTH1602CT (10 A) instead of DPG30C200PB (15 A)?

A: STTH1602CT is electrically compatible with DPG30C200PB in all parameters except current rating. Substitution is valid only if the circuit design operates at or below 10 A per diode. The device will function correctly at lower currents but cannot support the full 15 A specification.

Q: Why is SBR10200CT not recommended despite technical compatibility?

A: SBR10200CT is discontinued at DiGi Electronics and should not be selected for new designs. Active alternatives with equivalent or superior electrical characteristics are available from multiple manufacturers.

Q: Are all substitute parts available in the same packaging?

A: Yes. All listed substitute parts use TO-220-3 through-hole packaging, identical to the DPG30C200PB. No PCB layout modifications are required for mechanical compatibility.

Q: What is the operating temperature range difference between DPG30C200PB and substitute parts?

A: DPG30C200PB operates from -55°C to 175°C. Most STMicroelectronics and Diodes Incorporated substitutes operate from -65°C to 175°C, providing extended low-temperature capability. SBR10200CT is limited to -65°C to 150°C maximum junction temperature.

Q: How do reverse recovery times affect circuit performance?

A: Reverse recovery time (trr) affects switching speed and electromagnetic interference characteristics. DPG30C200PB has 35 ns trr. STTH3002CT (22 ns) and SBR10200CT (20 ns) offer faster recovery, reducing switching losses. STTH602CT and MUR620CTG match the 35 ns specification. Selection depends on switching frequency and EMI requirements.

Q: Can I mix different substitute parts in the same circuit?

A: All listed substitutes are electrically compatible within their rated specifications. However, using identical part numbers throughout a design ensures consistent performance characteristics and simplifies inventory management.
