Engineering Selection Recommendations

STPS30L30CG-TR (STMicroelectronics)

The STPS30L30CG-TR is the direct equivalent substitute for the obsolete STPS30L30CG. This part maintains identical electrical specifications including 30 V reverse voltage rating, 15 A average rectified current, and 460 mV forward voltage at 15 A. The component is manufactured by the same supplier (STMicroelectronics) and is classified as active product status, ensuring continued availability. Packaging is specified as Cut Tape (CT) & Digi-Reel®, providing standard supply chain compatibility. All compliance certifications including ROHS3, REACH Unaffected, and MSL 1 (Unlimited) are maintained. This substitute provides direct pin-for-pin and functional compatibility with no design modifications required.

SBM3045VDC_R2_00001 (Panjit International Inc.)

The SBM3045VDC_R2_00001 is a qualified substitute for applications where higher reverse voltage rating is acceptable or required. This part maintains the same diode configuration (1 pair common cathode), current rating (15 A per diode), and package type (TO-263-3, D2PAK). The reverse voltage rating is increased to 45 V, providing enhanced voltage margin compared to the original 30 V specification. Forward voltage is 480 mV at 15 A, representing a 20 mV increase from the original specification. Reverse leakage current is specified as 320 µA at 45 V. The component is active product status and ROHS3 compliant. This substitute is suitable for designs where the higher voltage rating does not create thermal or performance conflicts, and where the alternative manufacturer source is acceptable.

Frequently Asked Questions (FAQ)

Q: Can STPS30L30CG-TR be used as a direct replacement for STPS30L30CG?

A: Yes. The STPS30L30CG-TR is a direct equivalent substitute. Both parts share identical electrical specifications (30 V reverse voltage, 15 A current rating, 460 mV forward voltage at 15 A), the same diode configuration (1 pair common cathode), and identical package type (TO-263-3, D2PAK). The primary difference is product status: STPS30L30CG-TR is active while STPS30L30CG is obsolete. No design modifications or board layout changes are required.

Q: What is the difference between STPS30L30CG-TR and SBM3045VDC_R2_00001?

A: The primary electrical difference is the reverse voltage rating. STPS30L30CG-TR is rated for 30 V maximum reverse voltage, while SBM3045VDC_R2_00001 is rated for 45 V. Both maintain 15 A average rectified current and fast recovery Schottky technology. Forward voltage differs slightly: 460 mV versus 480 mV at 15 A. Both use identical TO-263-3 D2PAK packaging. The SBM3045VDC_R2_00001 is manufactured by Panjit International Inc., while STPS30L30CG-TR is manufactured by STMicroelectronics.

Q: Can SBM3045VDC_R2_00001 be used in a circuit designed for 30 V operation?

A: Yes. The SBM3045VDC_R2_00001 with 45 V reverse voltage rating is suitable for circuits designed for 30 V operation. The higher voltage rating provides additional safety margin and does not create incompatibility. The 20 mV increase in forward voltage (480 mV versus 460 mV at 15 A) is within acceptable tolerance for most Schottky diode applications. Thermal performance and current handling remain equivalent at 15 A per diode.

Q: Are all three parts RoHS compliant?

A: Yes. STPS30L30CG, STPS30L30CG-TR, and SBM3045VDC_R2_00001 are all ROHS3 compliant. All three parts have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: What is the difference in packaging between STPS30L30CG and STPS30L30CG-TR?

A: The electrical and mechanical specifications are identical. The packaging difference refers to supply format: STPS30L30CG is supplied in standard packaging, while STPS30L30CG-TR is supplied in Cut Tape (CT) & Digi-Reel® format. Both use the same TO-263-3 D2PAK component package. The supply format difference does not affect component performance or board-level compatibility.

Q: Can these parts be used interchangeably in high-temperature applications?

A: All three parts have identical maximum junction operating temperature of 150°C. They are suitable for equivalent high-temperature applications within this thermal limit. The SBM3045VDC_R2_00001 specifies an operating temperature range of -55°C to 150°C, providing explicit low-temperature specification not detailed for the STMicroelectronics parts.

Q: What is the significance of the "1 Pair Common Cathode" configuration?

A: This configuration indicates the diode array contains two diodes with a shared cathode connection. This internal connection topology must match the circuit design requirements. All three substitute parts maintain this identical configuration, ensuring functional compatibility in circuits designed for common cathode diode pair operation.
