Product details
Overview
TZ310N22KOFHPSA1 from Semikron is a phase-control thyristor module rated for 2200 V repetitive peak off-state voltage (VDRM/VRRM), 310 A average on-state current (ITAVM) at TC = 85°C, and 700 A RMS on-state current (ITRMSM), designed for high-power AC line commutation in industrial motor drives and medium-voltage rectifier bridges.
For engineers reviewing the TZ310N22KOFHPSA1 datasheet, TZ310N22KOFHPSA1 pinout, TZ310N22KOFHPSA1 application, or TZ310N22KOFHPSA1 equivalent, key selection criteria include critical dv/dt rating (500–1000 V/µs), gate trigger current (≤250 mA), junction-to-case thermal resistance (0.0745 °C/W), and forced-cooling-compatible mechanical torque specs (M2 terminals: 12 Nm ±10%).
Technical Context
This dual-thyristor B6-bridge module integrates two press-pack silicon pellets with AlN internal isolation and operates under line-commutated conditions. It supports sinusoidal conduction angles from 30° to 180° and delivers 9000 A non-repetitive surge current (10 ms, Tvj = 25°C).
The device features a low slope resistance of 0.86 mΩ and threshold voltage of 1 V at maximum junction temperature, enabling precise gate-controlled turn-on with ≤3.3 µs delay time. Its transient thermal impedance ZthJC is characterized analytically for both sinusoidal and rectangular current waveforms.

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 310/16 | Same 310 A ITAVM rating but lower VDRM/VRRM (1600 V); higher RthJC (0.085 °C/W). | Limited to ≤1100 Vrms AC systems; requires larger heatsink area for equivalent thermal performance. | Select when system voltage is ≤1100 Vrms and cost sensitivity outweighs voltage headroom needs. |
| TZ430N22KOFHPSA1 | Higher ITAVM (430 A) and ITRMSM (950 A); identical VDRM/VRRM and package footprint. | Direct upgrade path for higher current demand without layout change; same gate drive requirements. | Choose for future-proofing or derated operation where 30% current headroom improves reliability margin. |
Compared with SKKT 310/16, TZ310N22KOFHPSA1 provides 375 V higher blocking voltage and 0.0105 °C/W lower thermal resistance, enabling safer operation in 690 VAC+ industrial grids; versus TZ430N22KOFHPSA1, it trades 39% lower current rating for tighter cost control in fixed-load applications.

FAQ
What gate drive voltage and current are required for reliable triggering?
TZ310N22KOFHPSA1 requires ≤1.5 V gate trigger voltage and ≤250 mA gate trigger current at 25°C and 6 V anode-cathode voltage. For robust operation across temperature, gate drivers must deliver ≥350 mA peak current with <1 µs rise time to ensure turn-on within 3.3 µs even at Tvj = 125°C.
Can this module be used in natural convection cooling only?
Yes - with the KM17 heatsink (90 W rating) and three modules per heatsink, natural cooling supports up to 300 A ITAVM at Θ = 180° conduction. Derating is required below 180° due to higher RMS losses; full 310 A rating assumes forced-air cooling per datasheet curve on page 7.
What is the maximum allowable case temperature during operation?
The absolute maximum case temperature is 125°C, but the rated ITAVM = 310 A is specified at TC = 85°C. Operation up to 125°C is permitted only at reduced current - e.g., 220 A ITAVM at TC = 125°C per thermal curves on page 7 for sinusoidal loading.
How does the 6th letter 'F' in the part number affect specifications?
The 'F' denotes the critical dv/dt rating: 1000 V/µs at Tvj max (vs. 'C' = 500 V/µs). This higher rating reduces snubber component size and cost in fast-switching or high-dv/dt noise environments, such as proximity to IGBT inverters or long cable runs.
