Continuous Drain Current (Id) must equal or exceed 13A
RDS(on) characteristics must support equivalent on-state performance
Package type must be TO-252-3 (DPAK) or mechanically compatible surface mount configuration
Operating temperature range must encompass -55°C to 150°C

Identified Substitutes:

IPD50R280CEAUMA1 (Infineon Technologies): Direct manufacturer equivalent with identical electrical specifications. Differs only in packaging format (Cut Tape & Digi-Reel) and product status (Active vs. Discontinued). Maintains all critical parameters including 500V Vdss, 13A Id, and 280mOhm RDS(on).
STD18N55M5 (STMicroelectronics): Cross-manufacturer substitute with enhanced ratings. Provides 550V Vdss (50V margin above requirement), 16A Id (3A margin above requirement), and improved RDS(on) of 192mOhm at 8A. Maintains TO-252-3 package compatibility and surface mount configuration.

Engineering Selection Recommendations

IPD50R280CEAUMA1 Selection Criteria:

Select IPD50R280CEAUMA1 when direct parameter matching and manufacturer continuity are required. This part maintains identical electrical specifications to the discontinued IPD50R280CEATMA1 while offering active product status and improved availability (15,100 units in stock). Both parts are Infineon CoolMOS™ CE series devices with ROHS3 compliance. The primary distinction is packaging format (Cut Tape & Digi-Reel vs. standard packaging) and MSL rating (3, 168 Hours). This substitute is optimal for applications where design validation has been completed on the original part number and electrical parameter equivalence is the primary requirement.

STD18N55M5 Selection Criteria:

Select STD18N55M5 when enhanced performance margins and superior availability are acceptable. This STMicroelectronics MDmesh™ V device exceeds the original part specifications with 550V Vdss (vs. 500V), 16A Id (vs. 13A), and lower RDS(on) of 192mOhm (vs. 280mOhm). The device maintains TO-252-3 package compatibility and ROHS3 compliance. Key advantages include active product status, higher inventory (8,048 units), and MSL rating of 1 (Unlimited) for improved handling flexibility. The increased input capacitance (1260pF vs. 773pF) and higher gate threshold voltage (5V vs. 3.5V) require circuit evaluation for gate drive compatibility. This substitute is suitable for new designs or redesigns where performance enhancement and long-term availability are prioritized.

Frequently Asked Questions (FAQ)

Q: Can IPD50R280CEAUMA1 be used as a direct replacement for IPD50R280CEATMA1?

A: Yes. IPD50R280CEAUMA1 is a direct electrical equivalent with identical Vdss (500V), Id (13A), RDS(on) (280mOhm), and all other critical parameters. The only differences are packaging format (Cut Tape & Digi-Reel) and product status (Active). No circuit modifications are required.

Q: What are the limitations of using STD18N55M5 as a substitute?

A: STD18N55M5 has higher input capacitance (1260pF vs. 773pF) and higher gate threshold voltage (5V vs. 3.5V). These differences may affect gate drive circuit performance and switching speed. Circuit validation is required to confirm compatibility with existing gate drive circuitry. The device is otherwise electrically superior with higher voltage and current ratings.

Q: Are all three parts compatible with the same PCB layout?

A: Yes. All three parts use TO-252-3 (DPAK) package with identical pin configuration and mechanical dimensions. PCB layout and thermal management design remain unchanged. No layout modifications are necessary for substitution.

Q: What is the significance of the MSL rating difference between parts?

A: IPD50R280CEATMA1 and IPD50R280CEAUMA1 have MSL 3 (168 Hours), requiring controlled moisture exposure during storage and handling. STD18N55M5 has MSL 1 (Unlimited), allowing indefinite storage without moisture control measures. MSL 1 provides greater handling flexibility and reduced risk of moisture-related failures during assembly.

Q: Which substitute should be selected for new product designs?

A: For new designs, STD18N55M5 is recommended when performance margins and long-term availability are priorities. The enhanced specifications (550V, 16A, lower RDS(on)) provide design headroom. For designs requiring exact parameter matching to existing validation data, IPD50R280CEAUMA1 is appropriate.

Q: Are there compliance or certification differences between the substitutes?

A: All three parts are ROHS3 compliant and REACH unaffected. ECCN and HTSUS classifications are identical. No compliance barriers exist for substitution.
