SP8J65TB1

Overview

The SP8J65TB1 is a dual P-channel MOSFET manufactured by ROHM Semiconductor, designed for surface-mount applications in SOP-8 packages. It features a drain-source voltage of -30V and a continuous drain current of -7A per channel. The device exhibits a typical on-resistance of 29 mΩ at Vgs = -4.5V, with a gate threshold voltage of 2.5V. Key switching parameters include a total gate charge of 18 nC, a rise time of 40 ns, and a fall time of 65 ns. Power dissipation is rated at 2W, with an operating temperature range from -55°C to +150°C.

Feature Summary

• Dual P-channel configuration enables efficient high-side switching control within a compact footprint.
• Low on-resistance characteristics support reduced conduction losses in power management circuits.
• Fast switching speeds facilitate high-frequency operation suitable for modern DC/DC converters.

Applications

• High-side load switches in portable electronic devices
• Power management units for mobile communication equipment
• DC/DC converter input protection and control stages

Procurement Notes

Verify the specific ordering suffix against the manufacturer's official datasheet to ensure correct packaging and tape-and-reel specifications. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer prior to procurement. Ensure that the SOP-8 package dimensions match the target PCB layout requirements.

Selection Notes

Select this component when a dual P-channel solution is required for space-constrained designs. Evaluate the 29 mΩ on-resistance against thermal constraints at expected load currents. Consider the 18 nC gate charge for driver capability requirements. Verify that the -30V rating exceeds the maximum circuit voltage with adequate margin.

Part Context

This part belongs to ROHM's series of dual P-channel MOSFETs optimized for low-voltage, high-current applications. It serves as a complementary device to N-channel counterparts in half-bridge configurations. The SOP-8 package provides a balance between thermal performance and board space efficiency for consumer electronics.

Replacement Considerations

Consult the official ROHM replacement guide for verified cross-reference parts. Ensure any substitute maintains identical pinout, voltage ratings, and on-resistance characteristics. Verify package compatibility before implementation.
