PCP1405-TD-H

PCP1405-TD-H Description

The PCP1405-TD-H from onsemi is an N-channel MOSFET designed for medium-power switching applications, offering a robust 250V drain-to-source voltage (Vdss) and a continuous drain current (Id) of 600mA at 25°C. This surface-mount device is housed in a SOT-89 package, making it suitable for compact PCB designs. With a low gate charge (Qg) of 2.1 nC @ 4.5V and an input capacitance (Ciss) of 140 pF @ 20V, it ensures efficient switching performance. Although marked as Obsolete, it remains a reliable choice for legacy designs due to its RoHS3 compliance and REACH unaffected status.

PCP1405-TD-H Features

• High Voltage Tolerance: 250V Vdss for robust performance in power circuits.
• Low Gate Drive Requirements: Optimized for 2.5V–4.5V drive voltage, reducing control complexity.
• Low On-Resistance: 6.5Ω @ 300mA, 4.5V minimizes conduction losses.
• Wide Temperature Range: Operates up to 150°C (TJ), suitable for harsh environments.
• Fast Switching: Low Qg and Ciss enable high-frequency operation.
• Surface-Mount Design: SOT-89 package ensures space efficiency and ease of assembly (MSL 1).

PCP1405-TD-H Applications

• Power Management: DC-DC converters, load switches, and voltage regulation.
• Industrial Controls: Relay drivers, motor control, and solenoid drivers.
• Consumer Electronics: Battery protection circuits, LED drivers, and portable devices.
• Automotive Systems: Auxiliary power systems (non-critical, given obsolete status).

Conclusion of PCP1405-TD-H

The PCP1405-TD-H excels in applications demanding high voltage handling, low power dissipation (3.5W Tc), and compact form factors. Its low gate charge and on-resistance make it energy-efficient, while its SOT-89 packaging ensures versatility in space-constrained designs. Though obsolete, its proven reliability and compliance with environmental standards (RoHS3) make it a viable option for legacy or low-volume production. Ideal for engineers seeking a balance of performance and cost in industrial, consumer, and automotive low-power systems.
