Siemens A5E00135620 | IGD Inverter Trigger Board with IGBT Power Module — 90 kW / 110 kW / 132 kW Frequency Converter

Part Number: A5E00135620

Manufacturer: Siemens AG (Germany)

Product Type: IGD Trigger Board with IGBT Power Module — Drive Power Block Repair Assembly 

Overview

The A5E00135620 is an IGBT gate driver (IGD) trigger board supplied together with its matched IGBT power module, forming a complete drive power block repair assembly for Siemens AC frequency converters in the 90–132 kW power range. This board is the active switching core of the drive's inverter section — it generates the PWM gate pulses that switch the IGBT transistors, conditions the motor phase current measurements, and implements hardware desaturation protection.

At 90–132 kW, these drives appear across a wide range of heavy industrial applications: large pumps, centrifugal fans, compressors, extruders, and conveyors. A failed trigger board at this power level grounds the entire drive — no output, no motor rotation — making access to a tested replacement assembly a direct production reliability concern.

The A5E number places this assembly in Siemens' internal component series for drive power blocks. It is supplied as a matched pair — gate driver board and IGBT module together — ensuring that the gate drive characteristics are correctly calibrated for the specific IGBT device in the assembly. Replacing either component individually risks a gate drive mismatch.

Key Specifications

Gate Driver and IGBT — Matched Assembly

The IGD trigger board and the IGBT module are optimised for each other. The gate resistor values, driver output current, and timing margins on the board are selected to match the specific IGBT module's gate capacitance, threshold voltage, and switching speed.

Thermal interface material (TIM) between the IGBT module base plate and the drive heatsink is critical. Missing or incorrect TIM raises junction temperature significantly above the heatsink body temperature under load, causing F30022 overtemperature alarms even when the heatsink is cool to the touch.

FAQ

Q1: The drive shows F30001 (overcurrent) at run command with no motor connected. Is the A5E00135620 the cause?

With no load, any overcurrent reading is false. Measure DC resistance between output terminals with the bus discharged — a very low resistance confirms an IGBT short. If resistance is normal, the current measurement circuit on the trigger board has failed.

Q2: The drive failed during a mains surge. Should anything else be inspected before fitting a replacement A5E00135620?

Yes. Check the pre-charge circuit, DC bus fuses, and any MOV surge protection at the AC input. A surge strong enough to destroy the power block may have stressed the pre-charge resistors or damaged the Control Unit supply. Replace the power block first, then verify the drive initialises without further faults.

Q3: Can the IGBT module be replaced alone, without changing the trigger board?

No. The gate driver board is calibrated for the specific IGBT module. Replacing only the IGBT module introduces a mismatch between gate drive characteristics and device parameters. Always replace both components together as the matched A5E00135620 assembly.

Q4: After installation, the drive trips A30031 (power unit overtemperature) within minutes. The heatsink is cool. What is wrong?

Missing or incorrectly applied thermal interface material between the IGBT module and the heatsink is the cause in nearly all such cases. Remove the assembly, clean both surfaces, apply correct TIM, and re-install.

Q5: The A5E00135620 is discontinued. Where is a replacement sourced?

The specialist industrial drive aftermarket holds tested exchange assemblies for discontinued A5E power block series. Request a functional test certificate confirming all gate channels and current measurement circuits are verified before shipment.
