Product details
Overview
TZ630N28KOFHPSA1 from Semikron is a phase-control thyristor module rated for 630 A average on-state current (ITAVM) at TC = 85°C, 2800 V repetitive peak off-state voltage (VRRM), and 25.5 kA non-repetitive surge current (ITSM). It integrates two press-pack thyristor dies in a single insulated housing with AlN ceramic isolation, designed for high-power AC line commutated rectification in industrial medium-voltage drives.
For engineers reviewing the TZ630N28KOFHPSA1 datasheet, TZ630N28KOFHPSA1 pinout, TZ630N28KOFHPSA1 application, or TZ630N28KOFHPSA1 equivalent, key selection criteria include verified VDRM/VRRM rating, junction-to-case thermal resistance (RthJC ≤ 0.042 °C/W), gate trigger parameters (IGT ≤ 250 mA, VGT ≤ 2.0 V), and forced-cooling-compatible mechanical mounting torque (M1: 6 Nm ±15%).
Technical Context
This dual-thyristor module operates in line-commutated B2 (two-pulse) and B6 (six-pulse) bridge configurations, supporting AC input voltages up to 2.8 kV RMS. Its 125 °C maximum junction temperature and 3.0 kV RMS insulation test voltage enable use in 3.3 kV-class industrial converters.
The device features a critical dv/dt rating of 1000 V/µs and di/dt capability of 150 A/µs, ensuring reliable turn-off under high dv/dt transients and fast current rise conditions typical in motor drive and HVDC applications.
Key Specifications

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 |
|---|---|---|---|
| SKKT630/28E | Same ITAVM (630 A), lower VRRM (2400 V); integrated heat sink interface; higher RthJC (0.045 °C/W) | Limited to 2.4 kV systems; optimized for compact air-cooled enclosures | Select when space-constrained mounting and lower voltage rating are acceptable trade-offs |
| TT630N28KOF | Identical VRRM/ITAVM ratings; uses solder-bonded die instead of press-pack; RthJC = 0.040 °C/W | Lower assembly cost but reduced thermal cycle lifetime vs. press-pack construction | Select for cost-sensitive, non-critical applications where 10⁵ thermal cycles suffice |
Compared with SKKT630/28E and TT630N28KOF, TZ630N28KOFHPSA1 offers superior voltage margin (2800 V), press-pack reliability for >10⁶ cycles, and tighter thermal resistance-making it optimal for mission-critical 3.3 kV industrial rectifiers requiring long service life.

FAQ
What is the maximum allowable case temperature for continuous operation?
The maximum allowable case temperature (TC) is +125 °C, as defined by the 125 °C maximum junction temperature (Tvj max) and thermal resistance limits. At ITAVM = 630 A and TC = 85 °C, the device operates within its rated average current envelope per datasheet page 7. Exceeding TC = 125 °C risks irreversible degradation of the AlN isolation and Si die bonding.
Does TZ630N28KOFHPSA1 require external snubber circuits?
No external snubber is required for standard B2/B6 operation under specified dv/dt (≤20 V/µs) and di/dt (≤10 A/µs) conditions. Its 1000 V/µs critical dv/dt rating and 150 A/µs di/dt capability provide inherent immunity to typical line transients. Snubbers may still be needed in high-dv/dt environments like capacitor-input filters or long cable feeds.
How is gate drive isolation implemented in this module?
Each gate terminal (G1/G2) is electrically isolated from its respective cathode (K1/K2) and the baseplate by ≥3.0 kV RMS insulation. Gate non-trigger voltage (VGD ≤ 0.25 V) and non-trigger current (IGD ≤ 10 mA) specifications confirm isolation integrity. External gate drivers must provide ≥2.5 kV isolation between control and power grounds per IEC 61800-5-1.
Can TZ630N28KOFHPSA1 be used in anti-parallel configuration for AC output?
Yes-it is commonly deployed in anti-parallel pairs for AC output control in cycloconverters and static transfer switches. The 350 µs typical turn-off time (tq) and 23 kA ITSM rating at Tvj max support bidirectional current blocking and fast commutation. Mechanical mounting must ensure symmetric thermal paths and independent gate drive routing to prevent cross-talk.
