SV6020L2QTP Equivalent & Substitute Parts

Part Overview

The SV6020L2QTP is a Silicon Controlled Rectifier (SCR) manufactured by Littelfuse Inc., rated for 600 V off-state voltage and 20 A RMS on-state current. This thyristor device features a sensitive gate characteristic and is housed in a TO-220-3 isolated tab package for through-hole mounting applications. The part is active in production status and ROHS3 compliant.

Substitute parts are necessary when the primary part number becomes unavailable, when inventory constraints require alternative sourcing, or when application requirements permit operation with different SCR gate characteristics or current ratings within the same voltage class and package configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SV6020L2QTP is determined by the following critical parameters:

Mandatory Matching Parameters:

• Voltage - Off State: 600 V
• Package / Case: TO-220-3 Full Pack, Isolated Tab
• Mounting Type: Through Hole
• Operating Temperature Range: -40°C to 150°C (TJ)
• RoHS Status: ROHS3 Compliant

Flexible Parameters (Allow Variation):

• SCR Type: Sensitive Gate or Standard Recovery
• Current - On State (It RMS): 16 A, 20 A, or 25 A
• Current - On State (It AV): 10.2 A, 12.8 A, or 16 A
• Current - Non Rep. Surge (Itsm): 188 A / 225 A, 225 A / 300 A, or 300 A / 350 A

All substitute parts listed maintain identical gate trigger voltage, gate trigger current, on-state voltage, hold current, and off-state current specifications. Substitutes differ in maximum on-state current ratings and SCR recovery characteristics. Parts with equal or higher current ratings are direct substitutes for applications requiring the SV6020L2QTP's 20 A RMS capability. Parts with lower current ratings (16 A) are suitable only for applications with reduced current demands.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Equivalent Current Rating):

SJ6020L2TP is a direct parametric equivalent to SV6020L2QTP with identical 20 A RMS on-state current rating. The primary difference is SCR type classification: SJ6020L2TP features Standard Recovery characteristics versus the Sensitive Gate type of the main part. Both parts maintain all critical electrical parameters including gate trigger voltage, on-state voltage, and hold current. Both are ROHS3 compliant and active in production status.

Higher Current Substitutes (Uprated Capability):

SJ6025L2TP, SV6025L2QTP, and SV6025L2TP are rated for 25 A RMS on-state current, exceeding the SV6020L2QTP specification. These parts are suitable for applications where the SV6020L2QTP is specified but higher current capacity is available or required. All three maintain the 600 V off-state voltage, identical gate characteristics, and TO-220-3 package configuration. SV6025L2QTP and SV6025L2TP are classified as Sensitive Gate type, matching the main part's gate characteristic.

Lower Current Substitutes (Derated Operation):

SV6016L2QTP and SV6016L2TP are rated for 16 A RMS on-state current, below the SV6020L2QTP specification. These parts are suitable only for applications with reduced current demands or where the 20 A rating is not fully utilized. Both maintain 600 V off-state voltage and identical gate trigger specifications.

All substitute parts are ROHS3 compliant, REACH unaffected, and operate across the identical temperature range of -40°C to 150°C (TJ). All are housed in TO-220-3 isolated tab packages suitable for through-hole mounting.

Frequently Asked Questions (FAQ)

Q: Can SJ6020L2TP replace SV6020L2QTP in all applications?

A: SJ6020L2TP is a parametric equivalent with identical electrical specifications and current rating. The difference is SCR type: SJ6020L2TP uses Standard Recovery while SV6020L2QTP uses Sensitive Gate. Both maintain the same gate trigger voltage (1.5 V max), gate trigger current (10 mA max), on-state voltage (1.6 V max), and on-state current (20 A RMS). Substitution is valid where gate characteristic differences do not affect circuit performance.

Q: What is the difference between Sensitive Gate and Standard Recovery SCR types?

A: The input parameters provided specify these as distinct SCR type classifications. Both types in this product family maintain identical gate trigger voltage, gate trigger current, on-state voltage, hold current, and off-state current specifications. The classification difference reflects internal device characteristics not detailed in the provided parameters.

Q: Can I use SV6025L2TP (25 A) in place of SV6020L2QTP (20 A)?

A: Yes. SV6025L2TP is rated for 25 A RMS on-state current, which exceeds the 20 A requirement of SV6020L2QTP. All other electrical parameters are identical: 600 V off-state voltage, 1.5 V gate trigger voltage, 1.6 V on-state voltage, and 35 mA hold current. The higher current rating provides additional margin. Both use Sensitive Gate type and TO-220-3 isolated tab packaging.

Q: Can I use SV6016L2QTP (16 A) in place of SV6020L2QTP (20 A)?

A: SV6016L2QTP is rated for 16 A RMS on-state current, which is below the 20 A specification of SV6020L2QTP. This part is suitable only for applications where actual current demand does not exceed 16 A RMS. All other electrical parameters are identical. Substitution requires verification that circuit current requirements do not exceed 16 A RMS.

Q: Are all substitute parts in the same package?

A: Yes. All substitute parts listed use TO-220-3 Full Pack with isolated tab configuration (ITO-220AB supplier device package). All are through-hole mounted devices with identical mechanical compatibility.

Q: What is the inventory status of substitute parts?

A: SJ6020L2TP: 1321 Pcs; SJ6025L2TP: 1393 Pcs; SV6016L2QTP: 1952 Pcs; SV6016L2TP: 1822 Pcs; SV6025L2QTP: 1656 Pcs; SV6025L2TP: 1883 Pcs. All substitute parts are new original stock.

Q: Are all parts ROHS3 compliant?

A: Yes. The main part SV6020L2QTP and all listed substitute parts are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) and REACH Unaffected status.

Q: What is the operating temperature range for all parts?

A: All parts operate across -40°C to 150°C junction temperature (TJ) range.
