Engineering Selection Recommendations

STPS30150CW (STMicroelectronics)

The STPS30150CW is a direct functional equivalent to the 30CPQ150. Both parts share identical current ratings (15 A), voltage specifications (150 V), and operating temperature ranges. The STPS30150CW is classified as Active product status, ensuring long-term availability. This part is ROHS3 compliant and carries REACH Unaffected status. The forward voltage specification (920 mV @ 15 A) is marginally higher than the 30CPQ150 (1 V @ 15 A), and reverse leakage current is significantly lower (6.5 µA versus 100 µA), indicating improved performance characteristics. This part is the primary recommendation for direct replacement applications.

STPS61150CW (STMicroelectronics)

The STPS61150CW provides a higher current rating (30 A) while maintaining the same 150 V reverse voltage specification and TO-247-3 package. This part is suitable for applications where increased current capacity is required without circuit modification. The part is Active status with ROHS3 compliance. Forward voltage at 30 A operation (840 mV) and reverse leakage current (20 µA) demonstrate improved electrical characteristics compared to the 30CPQ150. Operating temperature range is specified as 175°C maximum, which covers the upper limit of the 30CPQ150 specification.

DSSK60-015A (IXYS)

The DSSK60-015A offers a 30 A current rating with 150 V reverse voltage specification in the TO-247-3 package. This part is Active status and ROHS3 compliant. The forward voltage specification (810 mV @ 30 A) and reverse leakage current (2 mA @ 150 V) reflect the higher current rating. Operating temperature range (-55°C to 175°C) matches the 30CPQ150 specification. This part is suitable for applications requiring elevated current capacity.

Frequently Asked Questions (FAQ)

Q: Can the STPS30150CW directly replace the 30CPQ150 without circuit modification?

A: Yes. The STPS30150CW maintains identical current (15 A) and voltage (150 V) specifications, the same diode configuration (1 Pair Common Cathode), and identical TO-247-3 through-hole packaging. No circuit modification is required for direct substitution.

Q: What is the advantage of using STPS61150CW or DSSK60-015A over STPS30150CW?

A: Both STPS61150CW and DSSK60-015A provide double the current rating (30 A versus 15 A) while maintaining the same 150 V voltage specification. These parts are suitable for applications where higher current capacity is needed. The circuit must be verified to confirm that the higher current rating does not introduce thermal or electrical stress in the application.

Q: Are all substitute parts compatible with the original 30CPQ150 PCB footprint?

A: Yes. All substitute parts use the TO-247-3 through-hole package, which maintains identical pin configuration and PCB footprint compatibility with the 30CPQ150.

Q: What is the difference in forward voltage between the 30CPQ150 and its substitutes?

A: The 30CPQ150 specifies 1 V forward voltage at 15 A. The STPS30150CW specifies 920 mV at 15 A, representing a 80 mV improvement. The higher-current parts (STPS61150CW at 840 mV @ 30 A and DSSK60-015A at 810 mV @ 30 A) show lower forward voltages due to their higher current ratings. Lower forward voltage reduces power dissipation in the application.

Q: Are the substitute parts RoHS compliant?

A: Yes. STPS30150CW, STPS61150CW, and DSSK60-015A are all ROHS3 compliant. The original 30CPQ150 is RoHS non-compliant. Substitution with any of these parts satisfies RoHS compliance requirements for new designs and production runs.

Q: What is the significance of reverse leakage current differences?

A: Reverse leakage current indicates the quality of the diode junction. Lower reverse leakage current (STPS30150CW at 6.5 µA, STPS61150CW at 20 µA, DSSK60-015A at 2 mA) compared to the 30CPQ150 (100 µA) represents improved diode characteristics and reduced parasitic current in reverse-biased conditions. This results in lower power consumption and improved circuit efficiency.

Q: Can the 30CPQ150 be used in new designs?

A: No. The 30CPQ150 is classified as obsolete. New designs must use active substitute parts. STPS30150CW is the recommended choice for direct functional replacement. STPS61150CW or DSSK60-015A are suitable alternatives for applications requiring higher current capacity.

Q: What is the operating temperature range for each substitute part?

A: STPS30150CW and STPS61150CW specify 175°C maximum junction temperature. DSSK60-015A specifies -55°C to 175°C operating range, which matches the 30CPQ150 specification. All parts are suitable for the full temperature range of the original component.
