Product details

Overview

TZ530N36KOFHPSA1 from Semikron is a phase-control thyristor module rated for 3600 V repetitive peak off-state voltage (V_DRM/V_RRM) and 530 A average on-state current (I_TAVM) at T_C = 85°C, with 22 kA non-repetitive surge capability (I_TSM) and 2.42×10⁶ A²s I²t rating. It integrates two press-pack thyristor dies in a single insulated housing for high-power AC line commutated rectification and motor control.

For engineers reviewing the TZ530N36KOFHPSA1 datasheet, TZ530N36KOFHPSA1 pinout, TZ530N36KOFHPSA1 application, or TZ530N36KOFHPSA1 equivalent, key selection criteria include its 125°C maximum junction temperature, 0.045°C/W junction-to-case thermal resistance, gate trigger current ≤250 mA, and compatibility with forced-cooled B2/B6 bridge topologies in industrial medium-voltage drives.

Technical Context

This dual-thyristor module operates in line-commutated mode with critical di/dt capability of 80 A/µs and dv/dt immunity up to 1000 V/µs (letter F), enabling robust turn-on under high-inductive loads. Its AlN-ceramic isolation and pressure-contact silicon pellet construction support 3.6 kV RMS insulation test voltage and 36 mm creepage distance for Class II safety compliance.

The device features a threshold voltage (V_(TO)) of 1.05 V and slope resistance (r_T) of 0.49 mΩ at T_vj = 125°C, delivering low conduction losses-e.g., 2.65 V on-state voltage at 3000 A-and 400 µs typical turn-off time (t_q) under specified commutation conditions.

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
SKKT530/36E	Same 3600 V/530 A rating but uses solder-bonded die and lower 0.055°C/W R_thJC; no pressure-contact construction.	Less suitable for high-cycle thermal environments; requires reflow-compatible PCB mounting instead of press-pack heatsink interface.	Select when board-level assembly and automated soldering are preferred over field-serviceable modular replacement.
TT530N36KOF	Identical electrical specs but lacks integrated gate terminals-requires external gate wiring and separate isolation.	Used in custom-designed modules where gate routing and thermal layout are fully controlled by OEM; not plug-in compatible.	Select only for vertically integrated power stack designs where gate layout and creepage are engineered in-house.

Compared with SKKT530/36E and TT530N36KOF, TZ530N36KOFHPSA1 uniquely combines press-pack reliability, integrated gate terminals with defined creepage, and AlN-based isolation-making it optimal for field-deployable, serviceable medium-voltage rectifier systems requiring long-term thermal stability.

FAQ

What is the maximum allowable case temperature for continuous operation?

The datasheet specifies a maximum case temperature (T_C) of 125°C for continuous operation when I_TAVM = 530 A at T_C = 85°C derating. Actual allowable T_C depends on current loading and thermal interface resistance; Figure 7 shows T_C vs. I_TAVM curves for sinusoidal and rectangular waveforms, with upper limit capped at 125°C regardless of conduction angle.

Does TZ530N36KOFHPSA1 require forced cooling?

Yes-forced cooling is mandatory for rated current operation. The datasheet assumes R_thCH ≤ 0.01°C/W and cites performance data for KW 70 heatsink at 4 L/min coolant flow. Natural convection or passive heatsinking cannot sustain 530 A I_TAVM; thermal modeling using Z_thJC and Z_thCA curves (pages 4–5) confirms >100°C junction rise without active cooling.

Can this module be used in inverter topologies?

It is not self-commutated and cannot operate as a standalone inverter switch. However, it supports forced-commutated inverters when paired with auxiliary turn-off circuits (e.g., LC snubbers or auxiliary thyristors), as evidenced by its 400 µs t_q spec and gate-controlled delay time ≤4 µs-enabling precise timing in line-commutated or hybrid inverter designs.

What is the meaning of "KOFHPSA1" in the part number?

Per Semikron's naming convention: K = 3600 V V_DRM/V_RRM, O = 400 µs typical t_q, F = 1000 V/µs (dv/dt)_cr, H = AlN isolation, P = press-pack construction, S = dual thyristor, A1 = standard gate terminal layout per datasheet page 3.
