STP22N60DM6 Equivalent & Substitute Parts

Part Overview

The STP22N60DM6 is an N-Channel MOSFET manufactured by STMicroelectronics, designed for high-voltage switching applications. This device features a 600V drain-to-source voltage rating with 15A continuous drain current capability in a through-hole TO-220 package. The part is currently in active production status with 814 units available in stock.

Substitute parts are necessary when the primary device becomes unavailable, when design requirements demand higher performance specifications, or when alternative sourcing is required for supply chain continuity. The FCP220N80 from onsemi represents an alternative solution with enhanced electrical characteristics, though it carries an obsolete product status designation.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for N-Channel MOSFETs is determined by the following criteria:

Package Compatibility: Both the main part and substitute must share the same physical package designation (TO-220-3 through-hole configuration) to ensure mechanical fit and thermal interface compatibility.

Voltage Rating: The substitute device must meet or exceed the drain-to-source voltage requirement of the application. The FCP220N80 provides 800V rating, which exceeds the 600V requirement of the STP22N60DM6.

Current Capability: The substitute must support the required continuous drain current. The FCP220N80 provides 23A continuous current, exceeding the 15A requirement.

On-State Resistance: Lower Rds On values indicate improved efficiency and reduced power dissipation. The FCP220N80 provides 220mOhm at 11.5A, 10V, compared to 240mOhm at 7.5A, 10V for the main part.

Gate Charge: Lower gate charge reduces switching losses and driver requirements. The FCP220N80 exhibits higher gate charge (105 nC) due to its enhanced current capability.

Temperature Range: Both devices operate across the identical temperature range of -55°C to 150°C.

Compliance Standards: Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment.

Engineering Selection Recommendations

Primary Selection (STP22N60DM6): This device is the preferred choice for new designs and applications requiring active production support. The part maintains active product status with established supply availability (814 units in stock). It provides optimized performance for 600V applications with lower gate charge (20.6 nC), reducing driver complexity and switching losses. The lower input capacitance (800 pF) simplifies gate drive circuit design.

Substitute Selection (FCP220N80): The FCP220N80 is suitable for applications where the primary part becomes unavailable or where enhanced performance specifications are beneficial. This device offers higher voltage rating (800V), increased current capability (23A), and superior power dissipation capacity (278W). However, the obsolete product status indicates limited future availability and potential supply constraints. The higher gate charge (105 nC) and input capacitance (4560 pF) require gate driver circuits with higher current capability. The maximum gate voltage rating is reduced to ±20V compared to ±25V for the main part.

Both devices maintain identical compliance certifications (ROHS3, REACH unaffected) and operate across the same temperature range, ensuring regulatory and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can the FCP220N80 be used as a direct replacement for the STP22N60DM6?

A: The FCP220N80 is mechanically compatible (identical TO-220-3 package) and electrically suitable for applications requiring 600V operation. However, the higher gate charge and input capacitance require gate driver circuits with increased current capability. The obsolete product status of the FCP220N80 limits its suitability for new designs.

Q: What are the key differences in electrical performance between these devices?

A: The FCP220N80 provides higher voltage rating (800V vs. 600V), greater current capability (23A vs. 15A), and higher power dissipation capacity (278W vs. 130W). The STP22N60DM6 features lower gate charge (20.6 nC vs. 105 nC) and significantly lower input capacitance (800 pF vs. 4560 pF), resulting in simpler gate drive requirements and lower switching losses.

Q: Are there thermal management differences between these devices?

A: Both devices operate across the identical temperature range (-55°C to 150°C). The FCP220N80 has higher maximum power dissipation (278W vs. 130W), which may require enhanced thermal management in high-power applications. The TO-220-3 package is identical for both devices, so thermal interface considerations remain consistent.

Q: What compliance certifications apply to both devices?

A: Both the STP22N60DM6 and FCP220N80 maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment for industrial and consumer applications.

Q: How does the gate voltage rating difference affect circuit design?

A: The STP22N60DM6 supports ±25V maximum gate voltage, while the FCP220N80 supports ±20V. Applications utilizing gate voltages between ±20V and ±25V require the STP22N60DM6. Standard gate drive circuits operating at ±15V or lower are compatible with both devices.

Q: What is the significance of the product status designation?

A: The STP22N60DM6 carries active product status, indicating ongoing production and long-term availability. The FCP220N80 is designated obsolete, meaning production has ceased and future availability is limited to existing inventory. New designs should prioritize the active product.
