FNA21012A

Overview

The onsemi FNA21012A is a single-chip AC induction motor driver belonging to the MotionSPM 2 series. It integrates three-phase output stages with a maximum IGBT collector current of 10 A and a maximum collector-emitter voltage of 1200 V. The device operates within a supply voltage range of 13.5 V to 16.5 V and supports a typical switching frequency of 20 kHz. Packaged in a 34-pin PDIP, it features an isolation rating of 2500 Vrms and functions reliably across an operating temperature range from -40 °C to +150 °C.

Feature Summary

• Integrates high-voltage IGBTs and gate drive circuitry for three-phase AC induction motor control
• Provides galvanic isolation between control and power sections via 2500 Vrms rating
• Designed for robust operation at elevated temperatures up to +150 °C

Applications

• Industrial motor drives
• HVAC compressor control systems
• Pump and fan speed regulation

Procurement Notes

Verify the specific ordering suffix against official onsemi documentation to confirm pinout compatibility and thermal characteristics. Ensure the procurement channel provides genuine components with traceable lot codes. Confirm that the PDIP-34 package dimensions align with the target PCB footprint before finalizing orders.

Selection Notes

Select this component when designing systems requiring integrated high-voltage switching for AC induction motors. The 1200 V rating suits applications with higher bus voltages, while the 10 A current capability supports moderate power loads. Consider the wide operating temperature range for environments with significant thermal stress without active cooling.

Part Context

This part belongs to the MotionSPM 2 series, which consolidates power semiconductors and intelligent gate drivers into a single module. This integration reduces board space and simplifies design compared to discrete solutions. The series targets efficient and compact motor control implementations in industrial and commercial sectors.

Replacement Considerations

Consult official cross-reference lists for direct equivalents. Verify that any substitute maintains the same 1200 V/10 A ratings, PDIP-34 package, and isolation specifications to ensure mechanical and electrical compatibility.
