Product details
Overview
TD150N26KOFHPSA1 from BIP AC is a phase-control thyristor module rated for 2600 V repetitive peak off-state voltage (VDRM/VRRM), 150 A average on-state current (ITAVM) at TC = 85°C, and 350 A RMS on-state current (ITRMSM), designed for industrial AC power control in medium-voltage rectifier and motor drive systems.
For engineers reviewing the TD150N26KOFHPSA1 datasheet, TD150N26KOFHPSA1 pinout, TD150N26KOFHPSA1 application, or TD150N26KOFHPSA1 equivalent, key selection criteria include critical dv/dt rating (1000 V/µs), gate trigger current (≤200 mA), junction-to-case thermal resistance (0.062 °C/W per module), and forced-cooling-compatible mechanical mounting (M2 terminal torque: 12 Nm).
Technical Context
This dual-thyristor (B6-bridge compatible) pressure-contact Si module uses AlN internal isolation and supports 180° conduction angle operation with 300 µs typical commutated turn-off time (tq) at Tvj max and vRM = 100 V. It delivers 2.6 V maximum on-state voltage (vT) at 600 A and 125 °C junction temperature.
The device features 6th-letter "F" coding for 1000 V/µs critical off-state voltage rise rate (dvD/dt)cr and 5th-letter "O" for 300 µs typical tq - confirming optimized performance for six-pulse bridge configurations under forced-air cooling with KM17 heatsinks.

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 |
|---|---|---|---|
| TT150N26KOFHPSA1 | Single-thyristor variant; same VDRM, ITAVM, and thermal specs but no complementary arm | Requires external pairing for full-bridge use; lower integration density | Select when discrete arm-level control or redundancy is required |
| DT150N26KOFHPSA1 | Dual-thyristor anti-parallel configuration; identical voltage/current ratings but different gate timing symmetry | Optimized for AC output switching (e.g., solid-state relays), not DC rectification | Select for bidirectional AC switching; avoid in unidirectional rectifier topologies |
Compared with TT150N26KOFHPSA1 and DT150N26KOFHPSA1, TD150N26KOFHPSA1 uniquely provides matched forward/reverse blocking in a single-module B6-bridge arm, enabling compact six-pulse rectifier designs without inter-module timing skew or thermal mismatch.

FAQ
What is the maximum allowable junction temperature for TD150N26KOFHPSA1?
The maximum junction temperature (Tvj max) is strictly limited to 125 °C per the datasheet. Exceeding this value risks irreversible degradation of the silicon die and AlN insulation. Thermal design must ensure RthJC + RthCH + RthHA ≤ (125 − TA)/Ptot, where Ptot includes both conduction and switching losses.
Does TD150N26KOFHPSA1 require a heatsink? If so, what type is recommended?
Yes - mandatory heatsinking is required. For forced-air cooling, BIP AC specifies KM17 heatsinks with Papst 4650N fans (RthCA ≈ 0.12 °C/W). For natural convection, KM17 (45W-rated) is usable only up to 75 A ITAVM. Mounting must use insulated hardware due to the electrically active baseplate.
Can TD150N26KOFHPSA1 be used in a single-phase full-wave bridge?
No - TD150N26KOFHPSA1 contains two thyristors configured for one arm of a three-phase B6 bridge (A1/K2 and K1/A2). A single-phase full-wave bridge requires four quadrant-controlled switches; this module lacks the terminal arrangement and internal topology for that topology.
What gate drive voltage and current are required for reliable turn-on?
Per datasheet, gate trigger voltage must exceed 2 V (VGT max) and gate trigger current must reach ≥200 mA (IGT max) at 25 °C with 6 V anode-cathode voltage. For margin, use 15–20 V pulses with ≥500 mA peak current and minimum 20 µs width to ensure latching at elevated temperatures.
