CPH5617-TL-E

Overview

The CPH5617-TL-E is an N-channel power MOSFET from onsemi, packaged in a CPH5 (SOT-25) configuration. It integrates two independent MOSFETs within a single package to improve mounting efficiency. The device supports a drain-to-source voltage of 30V and a continuous DC drain current of 150mA. Key electrical parameters include a maximum static drain-to-source on-state resistance of 3.7Ω at VGS=4V and ID=80mA, or 5.2Ω at VGS=2.5V and ID=40mA. The component operates with a gate-to-source voltage range of ±10V and features low input capacitance of 7.0pF.

Feature Summary

• Dual MOSFET structure integrated into one package for improved mounting efficiency
• Ultrahigh-speed switching capability with low total gate charge
• Capable of operation with low drive voltages down to 1.5V

Applications

• Low-voltage power management circuits
• Battery-powered portable devices requiring space-saving dual configurations
• Signal switching applications compatible with low logic levels

Procurement Notes

Verify the specific ordering suffix TL-E to confirm the tape-and-reel packaging format containing 3,000 pieces per reel. Ensure the procurement documentation explicitly states Pb-Free status as indicated in the official datasheet specifications. Cross-reference the manufacturer part number CPH5617-TL-E against the distributor catalog to confirm availability and correct component identification before finalizing orders.

Selection Notes

Select this component when a compact dual-N-channel solution is required for low-voltage applications up to 30V. Evaluate the on-state resistance requirements against the available drive voltage; higher RDS(on) values apply at lower gate voltages such as 1.5V or 2.5V. Consider the thermal dissipation limits of 0.25W and the small SOT-25 footprint when designing the PCB layout and heat management strategy.

Part Context

This device belongs to the CPH5 series of composite MOSFETs manufactured by onsemi. The CPH5 package type corresponds to the SC-74A or SOT-25 surface-mount form factor. This series is designed to provide multiple transistor functions in a minimal footprint, distinguishing it from single-transistor equivalents by offering dual functionality within the same physical housing.

Replacement Considerations

Direct replacements must match the CPH5/SOT-25 package and N-channel polarity. Verify that substitute components support at least 30V VDS and 150mA ID. Check that the replacement offers comparable RDS(on) characteristics at the intended operating gate voltage and similar switching speeds to maintain circuit performance integrity.
