SH8J66TB1

Overview

The SH8J66TB1 is a dual P-channel MOSFET array manufactured by ROHM Semiconductor, housed in an 8-SOP surface-mount package. It features a drain-source voltage of 30V and a continuous drain current of 9A per channel. The device exhibits a typical on-resistance of 25 milliohms at Vgs=10V and a forward transconductance of 11 S minimum. Key switching parameters include a rise time of 60 ns and a fall time of 100 ns. Total gate charge is specified at 3.9 nC. The component supports power dissipation up to 2W and operates within a junction temperature range of -55°C to +150°C.

Feature Summary

• Dual P-channel configuration integrated into a compact SOP-8 surface-mount package for space-efficient circuit design.
• Low on-resistance characteristics enabling efficient power handling with minimal conduction losses.
• Optimized switching performance with defined rise and fall times suitable for high-frequency applications.

Applications

• DC-DC converter circuits requiring dual-channel control
• Motor driver interfaces for low-voltage systems
• Power management units in portable electronic devices

Procurement Notes

Verify the specific suffix TB1 corresponds to the tape-and-reel packaging format when sourcing. Confirm that the 8-SOP package dimensions align with your PCB footprint requirements. Ensure thermal management strategies account for the 2W power dissipation limit under expected load conditions. Cross-reference the RoHS compliance status with current regulatory standards for your target market.

Selection Notes

Select this component when a dual P-channel solution is required within a 30V system architecture. The 9A current rating suits moderate power loads, while the low gate charge facilitates faster switching transitions compared to higher-capacitance alternatives. Consider the SOP-8 form factor for automated assembly processes where board space is constrained relative to through-hole options.

Part Context

This part belongs to ROHM's series of dual MOSFET arrays designed for integrated power switching. The SH8J66TB1 specifically addresses applications needing two independent P-channel switches in a single package. It complements N-channel variants like the SH8KC6 by providing complementary polarity options for bridge or half-bridge configurations.

Replacement Considerations

Direct substitutes may include other dual P-channel MOSFETs from ROHM with similar voltage and current ratings, such as the SH8J65TB1. Verify pin compatibility and electrical specifications before substitution to ensure circuit integrity.
