VS-ST180S12P1VPBF Equivalent & Substitute Parts

Part Overview

The VS-ST180S12P1VPBF is a silicon-controlled rectifier (SCR) rated for 1.2 kV off-state voltage with a maximum RMS on-state current of 314 A. This thyristor is designed for chassis and stud mount applications in the TO-209AB package. The device is currently active in production with full RoHS3 compliance and unlimited moisture sensitivity rating.

Substitute parts are identified when electrical parameters and mechanical specifications remain within the allowable tolerances for the application, ensuring direct interchangeability without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the VS-ST180S12P1VPBF is determined by strict equivalence across the following critical parameters:

• Off-state voltage rating (1.2 kV)
• Gate trigger voltage and current specifications (Vgt ≤ 3 V, Igt ≤ 150 mA)
• On-state voltage drop (Vtm ≤ 1.75 V)
• RMS on-state current capability (314 A)
• Hold current specification (Ih ≤ 600 mA)
• Off-state leakage current (≤ 30 mA)
• Operating temperature range (-40°C to 125°C)
• Package configuration (TO-209AB stud mount)
• SCR recovery type (Standard Recovery)

Parts meeting all these criteria are classified as parametric equivalents and may be used interchangeably in applications designed for the VS-ST180S12P1VPBF.

Parameter Comparison

Engineering Selection Recommendations

Both the VS-ST180S12P1VPBF and VS-ST180S12P0VPBF are active production devices manufactured by Vishay General Semiconductor - Diodes Division. Both parts carry identical electrical specifications and are housed in the same TO-209AB stud mount package. Both devices maintain full RoHS3 compliance and REACH unaffected status, with unlimited moisture sensitivity rating (MSL 1).

Selection between these parts may be based on inventory availability and lead time considerations, as all electrical and mechanical parameters are equivalent. No circuit modifications or thermal re-analysis are required when substituting between these devices.

Frequently Asked Questions (FAQ)

Q: Can VS-ST180S12P0VPBF replace VS-ST180S12P1VPBF in existing designs?

A: Yes. Both parts share identical electrical ratings across all critical parameters including off-state voltage, gate trigger specifications, on-state voltage drop, RMS current capability, and operating temperature range. The TO-209AB stud mount package is identical. Direct substitution is permissible without circuit redesign.

Q: Are there differences in surge current capability between these parts?

A: The non-repetitive surge current ratings differ between the two parts. VS-ST180S12P1VPBF is rated for 4200 A (50 Hz) and 4400 A (60 Hz), while VS-ST180S12P0VPBF is rated for 5000 A (50 Hz) and 5230 A (60 Hz). If surge current performance is a design criterion, the specific application requirements must be evaluated against these ratings.

Q: Do both parts meet the same compliance standards?

A: Yes. Both VS-ST180S12P1VPBF and VS-ST180S12P0VPBF are RoHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited) moisture sensitivity rating. Both are classified as active products in current production.

Q: What is the significance of the part number suffix difference (P1 vs. P0)?

A: The suffix designates internal manufacturing or specification variants within the ST180 base product family. From an electrical and mechanical standpoint, both parts are equivalent for standard application requirements. The difference does not affect interchangeability based on the provided specifications.

Q: Is the TO-209AB package suitable for both high-current and high-temperature applications?

A: The TO-209AB stud mount package is designed for chassis mounting in applications requiring robust thermal management. Both parts operate across -40°C to 125°C. Thermal performance depends on mounting configuration, heatsinking, and circuit design rather than package type alone.
