IRL620S MOSFET N-Channel 200V 5.2A Equivalent & Substitute Parts

Part Overview

The IRL620S is an N-Channel MOSFET manufactured by Vishay Siliconix, rated for 200V drain-to-source voltage with 5.2A continuous drain current in a Surface Mount TO-263 (D2PAK) package. The device is classified as obsolete, necessitating identification of active equivalent and substitute parts for ongoing design requirements and procurement continuity. Equivalent parts maintain identical electrical and mechanical specifications, while substitute parts provide functional alternatives with modified performance characteristics within the same package family.

Engineering Selection Recommendations

Parametric Equivalents (Direct Replacement):

IRL620SPBF and SIHL620S-GE3 are parametric equivalents to the IRL620S, maintaining identical electrical specifications across all measured parameters. Both parts are manufactured by Vishay Siliconix in the same TO-263 (D2PAK) package. IRL620SPBF and SIHL620S-GE3 are classified as Active products with ROHS3 compliance, addressing the obsolescence status of the original IRL620S. These parts are suitable for direct substitution in applications requiring no design modification.

Manufacturer Recommended Substitute:

IRL630SPBF is a Vishay Siliconix N-Channel MOSFET rated for 200V with 9A continuous drain current, representing a higher-current variant within the same voltage class and package family. The IRL630SPBF exhibits reduced on-resistance (400 mOhm at 5.4A, 5V versus 800 mOhm at 3.1A, 10V) and increased power dissipation capability (74W at Tc versus 50W at Tc). This part is suitable for applications where the IRL620S current rating is marginal or where thermal performance improvements are beneficial. The IRL630SPBF is Active and ROHS3 compliant.

Alternative Manufacturer Substitute:

RCJ081N20TL is a Rohm Semiconductor N-Channel MOSFET rated for 200V with 8A continuous drain current in a TO-263 (D2PAK) package. This part provides comparable current handling to the IRL630SPBF with on-resistance of 770 mOhm at 4A, 10V. The RCJ081N20TL exhibits lower gate charge (8.5 nC at 10V) and input capacitance (330 pF at 25V) compared to the IRL620S, resulting in faster switching characteristics. The higher gate threshold voltage (5.25V at 1mA) and extended maximum gate voltage rating (±30V) distinguish this part for specific gate drive circuit requirements. RCJ081N20TL is Active and ROHS3 compliant.

Frequently Asked Questions (FAQ)

Q: Can IRL620SPBF be used as a direct replacement for IRL620S?

A: Yes. IRL620SPBF is a parametric equivalent with identical electrical specifications. Both parts are N-Channel MOSFETs rated for 200V, 5.2A continuous drain current, with matching on-resistance, gate charge, and input capacitance. The primary difference is product status: IRL620SPBF is Active with ROHS3 compliance, while IRL620S is Obsolete and RoHS non-compliant. Mechanical compatibility is confirmed through identical TO-263 (D2PAK) packaging.

Q: What is the difference between IRL620SPBF and SIHL620S-GE3?

A: Both parts are parametric equivalents to the IRL620S with identical electrical specifications. SIHL620S-GE3 is designated as a Logic MOSFET variant by Vishay Siliconix. Both are Active, ROHS3 compliant, and packaged in TO-263 (D2PAK). Selection between these parts depends on availability and supplier preference, as electrical performance is equivalent.

Q: When should IRL630SPBF be selected instead of IRL620SPBF?

A: IRL630SPBF is selected when the application requires higher continuous drain current (9A versus 5.2A) or improved thermal performance (74W at Tc versus 50W at Tc). The reduced on-resistance (400 mOhm at 5.4A, 5V) results in lower power dissipation during operation. However, IRL630SPBF exhibits higher gate charge (40 nC at 10V versus 16 nC at 5V) and input capacitance (1100 pF at 25V versus 360 pF at 25V), requiring gate drive circuit evaluation for switching speed compatibility.

Q: Is RCJ081N20TL compatible with circuits designed for IRL620S?

A: RCJ081N20TL is mechanically compatible (TO-263 D2PAK package) and electrically compatible for voltage and current ratings (200V, 8A). However, gate drive circuit compatibility must be verified. RCJ081N20TL has a higher gate threshold voltage (5.25V at 1mA versus 2V at 250µA) and extended maximum gate voltage rating (±30V versus ±10V). These differences may require gate drive circuit adjustment to ensure proper switching operation. Lower gate charge (8.5 nC) and input capacitance (330 pF) provide faster switching characteristics.

Q: What is the significance of RoHS compliance in selecting a substitute?

A: IRL620S is RoHS non-compliant, while all substitute parts (IRL620SPBF, SIHL620S-GE3, IRL630SPBF, RCJ081N20TL) are ROHS3 compliant. RoHS3 compliance is mandatory for products sold into regulated markets and is increasingly required by original equipment manufacturers. Selection of ROHS3 compliant substitutes ensures regulatory compliance and supply chain continuity.

Q: Can multiple substitute parts be used interchangeably in production?

A: IRL620SPBF and SIHL620S-GE3 are fully interchangeable as parametric equivalents. IRL630SPBF and RCJ081N20TL are not interchangeable with IRL620SPBF without circuit evaluation due to differences in gate charge, input capacitance, and gate threshold voltage. If multiple parts are used in production, gate drive circuit compatibility and thermal performance must be verified for each substitute to ensure consistent device operation across the product line.

Q: What packaging considerations apply to these substitutes?

A: All substitute parts are packaged in TO-263 (D2PAK) with identical pin configuration (2 Leads + Tab). Mechanical compatibility is confirmed for PCB layout and thermal management. Moisture sensitivity level (MSL 1 - Unlimited) is identical across all parts, indicating no special storage or handling requirements. Supplier packaging formats vary (Tube, Cut Tape, Digi-Reel) but do not affect electrical or mechanical compatibility.
