M54531P and M54531FP are seven-circuit Darlington transistor arrays with clamping diodes. The circuits are made of NPN transistors and perform high-current driving with extremely low input-current supply. They feature high breakdown voltage, high-current driving, clamping diodes, driving available with PMOS IC output, wide input voltage range, and wide operating temperature range.
The M54531P and M54531FP are seven‑circuit Darlington transistor arrays with integrated clamping diodes, built from NPN transistors. They are intended for high‑current driving applications such as relays, printers, LEDs, lamps, and MOS‑bipolar logic interfaces.
Key specifications include a collector‑emitter breakdown voltage of 40 V, a maximum collector current of 400 mA per circuit, a wide input voltage range of –40 V to +40 V, and operation over –20 °C to +75 °C. The devices are supplied in a 16‑pin flat package (16P2N‑A for P version, 16P2N‑A(FP) for FP version) and feature a built‑in clamping diode on each output pin.
