Overview
The CP15TD1-24A is a power semiconductor module from Powerex Inc., a joint venture between General Electric and Mitsubishi Electric. It is a highly integrated DIP-CIB (Dual-In-line Package, Converter, Inverter, Brake) module designed to control three-phase AC motors. Its key feature is the integration of three distinct power circuits—a three-phase diode converter, a three-phase IGBT inverter, and an IGBT brake circuit—into a single, compact, through-hole package.
This all-in-one design makes it a convenient solution for applications requiring a full-bridge power stage. The module also includes an integrated NTC thermistor for temperature sensing, which helps in implementing thermal protection for the system.

Pin Configuration Explained
The CP15TD1-24A comes in a Dual In-line Package (DIP) with a total of 26 pins, arranged in two rows for through-hole mounting on a circuit board. Below is a detailed breakdown of each pin's function and grouping:
Pins 1-3 (TH1, TH2, P1): Located on the top left, these pins correspond to the thermistor (TH1, TH2) and the load side (P1). The thermistor monitors the module's internal temperature, providing a signal for overheating protection.
Pins 4-6 (GUP, GVP, GWP): This group provides the gate drive power for the upper-arm IGBTs. They supply positive voltage for the U, V, and W phase upper-arm drives, respectively.
Pins 7-9 (EUP, EVP, EWP): These are the emitter pins for the upper-arm IGBTs. They serve as the return path for the drive signals, working in tandem with the gate drive power pins.
Pins 10-12 (GB, N(B), B): These three pins are for the brake circuit. GB is the gate for the brake IGBT, while N(B) and B are its emitter and collector, respectively. The brake circuit is mainly used to control the reverse energy generated when a motor is rapidly stopped.
Pins 13-15 (R, T): These two pins are for the brake resistor and the AC input of the three-phase rectifier bridge. R connects the brake resistor, while T and S (pin 16) are two of the three input phases for the power supply.
Pins 16-18 (S, N1, GUN): This group includes the three-phase power input (S), the lower-arm gate drive power (N1), and the gate for the U-phase lower arm (GUN).
Pins 19-21 (UN, GWN, VN): These three pins are the U-phase emitter (UN), the gate for the W-phase lower arm (GWN), and the V-phase emitter (VN), respectively.
Pins 22-24 (GWN, WN, V): This group consists of the gate for the W-phase lower arm (GWN), the W-phase emitter (WN), and the gate for the V-phase lower arm (V).
Pins 25-26 (V, W): These are the DC output terminals of the rectifier bridge. V and W are the DC negative and positive poles, respectively.
Replacements and Alternatives
Since the CP15TD1-24A is obsolete, a direct, drop-in replacement is generally not available. Any new design would require using a modern alternative. Powerex and its partners have moved towards more efficient and compact technologies, including Silicon Carbide (SiC)-based modules.
If you need a replacement for a repair or a new design, consider these options:
Modern IGBT Modules: Look for newer IGBT modules from manufacturers like Mitsubishi Electric, Infineon, or Fuji Electric with similar voltage and current ratings (e.g., 1200V / 15A). Be aware that these modules will likely have different pinouts and packages, requiring a redesign of the circuit board.
Modular Approach: Instead of using a single integrated CIB module, a modern approach would be to use separate, smaller modules or discrete components for the converter, inverter, and brake circuits. This provides greater design flexibility and allows for the use of more efficient and widely available parts.
For a new design, the shift from older silicon technology to modern SiC-based components offers significant benefits, including lower power loss, higher switching frequencies, and a smaller footprint, ultimately leading to a more efficient and compact final product.
