Product details
Overview
TD142N16KOFHPSA1 from Semikron is a phase-control thyristor module with dual anti-parallel SCR configuration, rated for 1600 V repetitive peak off-state voltage (VDRM/VRRM), 142 A average on-state current (ITAVM) at TC = 85°C, and 230 A RMS on-state current (ITRMSM). It delivers robust line-frequency AC power control in industrial rectifiers and motor drives.
For engineers reviewing the TD142N16KOFHPSA1 datasheet, TD142N16KOFHPSA1 pinout, TD142N16KOFHPSA1 application, or TD142N16KOFHPSA1 equivalent, key selection criteria include critical dv/dt rating (1000 V/µs), junction-to-case thermal resistance (0.110 °C/W per module), gate trigger current (≤150 mA), and surge current capability (4800 A, 10 ms).
Technical Context
This dual SCR module operates in forced- or natural-cooled phase-controlled AC applications, supporting B2 (two-pulse) and B6 (six-pulse) bridge topologies. Its 125 °C maximum junction temperature and AlN internal insulation enable stable operation under high thermal stress.
The device features a pressure-contact silicon pellet construction, 2.5 kV (1 min) insulation test voltage, and 150 A/µs critical di/dt rating-ensuring reliable turn-on under inductive load conditions without false triggering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDRM / VRRM | 1600 V - Maximum repetitive blocking voltage in both forward and reverse directions, defining usable AC line voltage range up to 1100 V RMS. |
| ITAVM @ TC=85°C | 142 A - Continuous DC-equivalent current per arm, setting steady-state power handling in rectifier arms. |
| ITRMSM | 230 A - RMS current rating per module, used for thermal design of heatsink and cooling system. |
| (dvD/dt)cr | 1000 V/µs - Minimum rate of rise of off-state voltage before spurious turn-on, critical for snubberless operation in noisy industrial environments. |
| RthJC (per module) | 0.110 °C/W - Junction-to-case thermal resistance under DC conduction, directly determining temperature rise under given power loss. |
| vT max @ iT=500 A | 1.56 V - Maximum on-state voltage drop, used to calculate conduction losses (P = vT × ITAV + rT × I²TAV). |
| IGT max | 150 mA - Maximum gate trigger current required at 25°C and 6 V anode-cathode voltage, defining minimum driver output capability. |
Pinout & Package
TD142N16KOFHPSA1 is housed in a press-pack module package with isolated copper baseplate and screw terminals. The mechanical layout follows Semikron's standard dual-arm thyristor module footprint (see datasheet page 3), featuring two main power terminals (A1/K1 and A2/K2) and two isolated gate terminals (G1 and G2), plus case ground via mounting screws.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| A1 / K1 | Anode 1 / Cathode 1 | Main current path for first SCR arm; A1 is anode, K1 is cathode-anti-parallel to second arm. |
| A2 / K2 | Anode 2 / Cathode 2 | Main current path for second SCR arm; configured anti-parallel to first arm for bidirectional AC conduction. |
| G1 | Gate 1 | Isolated low-power control input for first SCR; requires ≤150 mA trigger current at 25°C. |
| G2 | Gate 2 | Isolated low-power control input for second SCR; electrically separated to prevent cross-talk in phase-shifted firing. |
| Case | Thermal & Electrical Reference | Electrically isolated copper baseplate (AlN insulation); serves as primary heat transfer surface and functional earth reference point. |
Key Features
| Feature | Design Value |
|---|---|
| Dual anti-parallel SCR configuration | Enables full-wave AC phase control without external back-to-back assembly-reducing PCB space and interconnect inductance. |
| AlN ceramic internal isolation | Provides 2.5 kV RMS insulation strength and stable thermal performance across -40°C to +130°C storage range. |
| Pressure-contact Si pellet | Eliminates wire bonds and solder interfaces-improving long-term reliability under thermal cycling in industrial drive systems. |
| 1000 V/µs critical dv/dt | Supports snubberless operation in high-dv/dt environments like transformer-fed rectifiers and regenerative braking circuits. |
| 0.110 °C/W RthJC (DC) | Enables compact heatsink design for 142 A continuous operation when paired with forced-air cooling (e.g., Papst 4650N fan). |
Applications
| Industrial DC Motor Drive | Medium-Voltage Rectifier System |
|---|---|
Use Scenario: Speed-controlled DC motor supply in rolling mill drives and crane hoists operating from 400–690 V AC mains. IC Role / Device Role / Timing Role: Dual-arm phase-controlled rectification with synchronized gate firing to regulate average output voltage. Use Value: Delivers 142 A continuous DC output with <1.56 V conduction drop, minimizing thermal stress on heatsink under 100% duty cycle. | Use Scenario: Six-pulse (B6) rectification in electroplating and electrolysis power supplies requiring stable 500–1000 A DC output. IC Role / Device Role / Timing Role: One module per arm in three-phase bridge; handles 230 A RMS per arm under 120° conduction. Use Value: Supports parallel operation with matched thermal impedance (ZthJC), enabling scalable multi-module designs with uniform current sharing. |
| AC Power Controller for Resistive Loads | Regenerative Braking Interface |
Use Scenario: Temperature-controlled heating in industrial ovens and furnaces using 3-phase resistive elements. IC Role / Device Role / Timing Role: Two-pulse (B2) back-to-back switching per phase to modulate RMS power delivered to load. Use Value: Leverages 1600 V blocking rating to safely operate on 690 V AC lines with margin, while 150 A/µs di/dt rating prevents commutation failure during zero-crossing switching. | Use Scenario: Bidirectional energy flow control in elevator and mining hoist drives during descent regeneration. IC Role / Device Role / Timing Role: Reverse-conducting arm absorbs regenerated AC current and feeds it back to line via active inversion timing. Use Value: 4800 A non-repetitive surge rating withstands transient overcurrents during emergency stop events without latch-up or thermal runaway. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar phase-control thyristor module applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SKKT 142/16E | Same VDRM/VRRM (1600 V) and ITAVM (142 A), but uses solder-bonded die and lower (dv/dt)cr (600 V/µs). | Requires snubber networks in high-noise environments where TD142N16KOFHPSA1 operates snubberless. | Select when cost sensitivity outweighs dv/dt margin and thermal cycling endurance requirements. |
| TT142N16KOFHPSA1 | Identical electrical ratings and pinout, but single-arm configuration-requires two units for full-wave AC control. | Increases board area and gate drive complexity versus integrated dual-arm TD142N16KOFHPSA1. | Select only if legacy system design mandates discrete single-arm modules or separate thermal management per arm. |
Compared with SKKT 142/16E and TT142N16KOFHPSA1, TD142N16KOFHPSA1 offers superior dv/dt immunity and pressure-contact reliability for high-cycle industrial drives, while reducing component count and thermal interface layers in B2/B6 rectifier designs.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum case temperature (TC) is not fixed-it depends on ITAVM and conduction angle. At ITAVM = 142 A and Θ = 180°, TC must not exceed 85°C for rated current. Full derating applies above that; see datasheet page 7 for TC vs. ITAVM curves under sinusoidal and rectangular current.
Can TD142N16KOFHPSA1 be used in parallel configurations?
Yes-its matched dynamic parameters (vT, tq, (di/dt)cr) and low RthJC (0.110 °C/W) support parallel operation. Use identical gate drive timing, symmetrical busbar layout, and individual current-sharing reactors or ballast resistors to ensure balanced loading per arm.
What gate drive voltage and current are required for reliable turn-on?
At 25°C and vD = 6 V, gate trigger current must reach ≥150 mA within 20 µs (iGM = 0.6 A, diG/dt = 0.6 A/µs). Gate trigger voltage must exceed 2 V. For robustness at Tvj = 125°C, design for ≥200 mA peak gate current and ≥3 V pulse amplitude.
Is the module RoHS-compliant and halogen-free?
Yes-TD142N16KOFHPSA1 complies with EU RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The AlN insulator, copper baseplate, and tin-plated terminals meet all substance restrictions; full compliance documentation is available upon request.
