Key Parameters

Substitute Part Grouping Explanation

Substitution of the TSM5NC50CP is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

• FET Type: N-Channel
• Technology: MOSFET (Metal Oxide)
• Drain to Source Voltage (Vdss): 500V minimum
• Continuous Drain Current (Id) @ 25°C: 5A minimum
• Drive Voltage: 10V
• Mounting Type: Surface Mount
• Package / Case: TO-252 (DPAK) compatible
• Operating Temperature Range: -55°C to 150°C (TJ)
• RoHS Compliance: ROHS3 Compliant

Parametric Equivalent Classification: Parts meeting all primary criteria with identical or superior electrical specifications and identical package form factor are classified as parametric equivalents. The TSM5NC50CP ROG variant from Taiwan Semiconductor Corporation qualifies as a parametric equivalent, differing only in packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and product status (Obsolete versus Active).

Similar Manufacturer Classification: Parts meeting primary criteria with minor deviations in secondary parameters (such as Rds On, Gate Charge, or Input Capacitance within acceptable engineering tolerances) are classified as similar manufacturers. The STD5N52U from STMicroelectronics qualifies under this classification, with a Vdss rating of 525V (exceeding the 500V requirement) and a continuous drain current of 4.4A (within acceptable tolerance of the 5A specification).

Parameter Comparison

Engineering Selection Recommendations

TSM5NC50CP ROG (Parametric Equivalent): The TSM5NC50CP ROG is a parametric equivalent offering identical electrical specifications and package form factor to the main part. Both devices are manufactured by Taiwan Semiconductor Corporation and comply with ROHS3 standards. The primary distinction is product status: the main part is Active while the ROG variant is Obsolete. Selection of the TSM5NC50CP ROG is appropriate for applications where packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) aligns with procurement requirements. However, the Obsolete status indicates limited future availability and should be considered in long-term supply chain planning.

STD5N52U (Similar Manufacturer): The STD5N52U from STMicroelectronics is classified as a similar manufacturer substitute. This device maintains Active product status and offers a higher Vdss rating of 525V, providing additional voltage margin over the 500V specification. The continuous drain current is rated at 4.4A, which is 0.6A lower than the TSM5NC50CP specification. The STD5N52U exhibits slightly higher Rds On (1.5 Ohm versus 1.38 Ohm) and marginally higher Gate Charge (16.9 nC versus 15 nC). Power dissipation is rated at 70W, which is 13W lower than the main part. The STD5N52U is suitable for applications where the reduced current rating and power dissipation do not constrain circuit performance, and where the higher voltage rating provides design margin. The device is ROHS3 compliant and carries an MSL rating of 1 (Unlimited), indicating superior moisture handling characteristics compared to the main part.

Selection Basis:

• For direct replacement with identical specifications: TSM5NC50CP (Active status, full availability)
• For parametric equivalence with alternative packaging: TSM5NC50CP ROG (identical electrical performance, limited availability due to Obsolete status)
• For alternative manufacturer with enhanced voltage rating: STD5N52U (Active status, higher Vdss, reduced current and power ratings, superior MSL rating)

Frequently Asked Questions (FAQ)

Q: Can the TSM5NC50CP ROG be used as a direct replacement for the TSM5NC50CP?

A: Yes. The TSM5NC50CP ROG is a parametric equivalent with identical electrical specifications, including Vdss (500V), continuous drain current (5A), Rds On (1.38 Ohm @ 2.4A, 10V), and power dissipation (83W). Both devices use the TO-252 (DPAK) package. The difference is packaging format: the main part is supplied in Tape & Reel (TR) format, while the ROG variant is supplied in Cut Tape (CT) & Digi-Reel® format. Electrical and mechanical compatibility is complete. The Obsolete product status of the ROG variant should be considered for long-term supply planning.

Q: Is the STD5N52U a suitable substitute for the TSM5NC50CP?

A: The STD5N52U is a similar manufacturer substitute with compatible electrical characteristics for many applications. Both devices are N-Channel MOSFETs in TO-252 (DPAK) packages with identical operating temperature ranges (-55°C to 150°C) and gate voltage specifications (±30V). The STD5N52U offers a higher Vdss rating (525V versus 500V), which provides additional voltage margin. However, the continuous drain current is 4.4A compared to 5A, and power dissipation is 70W compared to 83W. Substitution is appropriate when the application does not require the full 5A current rating or 83W power dissipation of the main part. The STD5N52U is Active status with superior moisture sensitivity characteristics (MSL 1 versus MSL 3).

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by the following parameters: FET Type (N-Channel), Technology (MOSFET Metal Oxide), Drain to Source Voltage (Vdss ≥ 500V), Continuous Drain Current (Id ≥ 5A @ 25°C), Drive Voltage (10V), Gate Voltage (±30V), Operating Temperature Range (-55°C to 150°C), and Package Form Factor (TO-252 DPAK). Secondary parameters including Rds On, Gate Charge, Input Capacitance, and Power Dissipation determine the degree of substitution (parametric equivalent versus similar manufacturer). All substitute parts must comply with ROHS3 standards.

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

A: Yes. The TSM5NC50CP, TSM5NC50CP ROG, and STD5N52U are all housed in the TO-252-3 (DPAK with 2 Leads + Tab, SC-63) package. This ensures mechanical and pin compatibility for direct board-level substitution. The difference between the main part and ROG variant is the supply format (Tape & Reel versus Cut Tape & Digi-Reel®), not the physical package.

Q: What is the significance of the Obsolete product status for the TSM5NC50CP ROG?

A: Obsolete product status indicates that the TSM5NC50CP ROG is no longer in active production and future availability is limited. While the part is currently in stock (33,288 pieces), procurement of additional units may become difficult or impossible as inventory depletes. For new designs or long-term production requirements, the Active status TSM5NC50CP or STD5N52U is recommended to ensure sustained supply chain availability.

Q: How do the Rds On specifications compare between the substitute parts?

A: The TSM5NC50CP and TSM5NC50CP ROG both specify Rds On (Max) of 1.38 Ohm at 2.4A and 10V gate voltage. The STD5N52U specifies Rds On (Max) of 1.5 Ohm at 2.2A and 10V gate voltage. The 0.12 Ohm difference represents approximately 8.7% higher on-resistance for the STD5N52U. This difference affects power dissipation and thermal performance; applications with tight thermal budgets should account for this variance.

Q: What is the difference in Gate Charge between the parts?

A: The TSM5NC50CP and TSM5NC50CP ROG both specify Gate Charge (Qg) of 15 nC at 10V. The STD5N52U specifies Gate Charge of 16.9 nC at 10V, representing approximately 12.7% higher gate charge. Higher gate charge increases driver circuit current requirements and switching losses; applications with high switching frequencies should account for this difference.

Q: Are all substitute parts RoHS compliant?

A: Yes. The TSM5NC50CP, TSM5NC50CP ROG, and STD5N52U are all ROHS3 compliant. All parts are also REACH Unaffected. This ensures compliance with environmental and regulatory requirements for applications subject to RoHS and REACH directives.
