Engineering Selection Recommendations

The DPG30C200PB is the identified substitute for the obsolete DSEC29-02A. Both components are manufactured by IXYS and belong to the HiPerFRED™ series.

Product Status Consideration: The DSEC29-02A is obsolete, while the DPG30C200PB is active. Selection of the DPG30C200PB ensures access to current inventory and ongoing manufacturer support.

Compliance Status: The DPG30C200PB carries RoHS3 compliance certification, whereas the DSEC29-02A compliance status is not specified in the provided data. Both components are REACH Unaffected and classified under ECCN EAR99.

Electrical Performance: The DPG30C200PB exhibits slightly higher forward voltage (1.26 V versus 1.06 V at 15 A) and longer reverse recovery time (35 ns versus 25 ns). These differences remain within acceptable tolerances for general-purpose rectification applications. The DPG30C200PB demonstrates superior reverse leakage characteristics (1 µA versus 100 µA at 200 V), indicating improved leakage performance.

Packaging: Both components utilize identical TO-220-3 through-hole packaging, ensuring mechanical and thermal compatibility in existing circuit board layouts.

Frequently Asked Questions (FAQ)

Q: Can the DPG30C200PB directly replace the DSEC29-02A in existing designs?

A: Yes. Both components share identical diode configuration (1 Pair Common Cathode), voltage rating (200 V), current rating (15 A), package type (TO-220-3), and operating temperature range (-55°C to 175°C). Pin-to-pin compatibility is maintained.

Q: What are the differences between these two parts?

A: The primary differences are forward voltage (1.26 V for DPG30C200PB versus 1.06 V for DSEC29-02A at 15 A), reverse recovery time (35 ns versus 25 ns), and reverse leakage current (1 µA versus 100 µA at 200 V). The DPG30C200PB is an active product with RoHS3 compliance, while the DSEC29-02A is obsolete.

Q: Will the higher forward voltage of the DPG30C200PB affect circuit performance?

A: The forward voltage difference of 0.20 V at 15 A is a minor variation typical between different diode manufacturing processes. Circuit designs must be evaluated based on specific application requirements and thermal dissipation characteristics.

Q: Is the longer reverse recovery time of the DPG30C200PB a concern?

A: The reverse recovery time difference of 10 ns (25 ns to 35 ns) remains within the fast recovery classification. Application-specific switching frequency and EMI requirements determine whether this difference is significant.

Q: What is the significance of the improved reverse leakage characteristics in the DPG30C200PB?

A: The DPG30C200PB exhibits 100 times lower reverse leakage current (1 µA versus 100 µA at 200 V). This improvement reduces standby power consumption and heat generation in applications with sustained reverse bias conditions.

Q: Are there any compliance or certification differences?

A: The DPG30C200PB is RoHS3 compliant. Both components are REACH Unaffected and classified under ECCN EAR99. Compliance requirements for specific applications must be verified against design specifications.

Q: What packaging options are available?

A: The DSEC29-02A is supplied in standard through-hole packaging. The DPG30C200PB is supplied in tube packaging. Both maintain identical TO-220-3 case dimensions and pin configuration.
