RN4907FE,LF(CT

Overview

The RN4907FE,LF(CT is a pre-biased digital transistor array manufactured by Toshiba Semiconductor and Storage. It integrates one NPN and one PNP bipolar junction transistor (BJT) within a single US6 surface-mount package. The device features built-in bias resistors to simplify circuit design. Key electrical specifications include a maximum collector-emitter voltage of 50V and a continuous collector current of 100mA. The DC current gain (hFE) has a minimum value of 80 at 10mA and 5V. The transition frequency is rated at 200MHz, with a maximum power dissipation of 200mW. Internal resistor values are typically 10kΩ for the base resistor (R1) and 47kΩ for the emitter-base resistor (R2).

Feature Summary

• Integrates complementary NPN and PNP transistors with built-in bias resistors in a compact SMD package.
• Simplifies circuit design by reducing component count and manufacturing processes.
• Provides high DC current gain suitable for switching and interface applications.

Applications

• Switching circuits
• Inverter circuits
• Interface circuits

Procurement Notes

Verify the specific suffix LF(CT against official Toshiba documentation to confirm lead-free status and cut-tape packaging format. Ensure compatibility with RoHS3 regulations if required by the target application. Cross-reference the DigiKey part number RN4907LFCT-ND for accurate ordering details and availability status from authorized distributors.

Selection Notes

Select this component when a complementary NPN/PNP pair with integrated biasing is required in a small footprint. The 10kΩ/47kΩ resistor configuration offers standard biasing characteristics. Consider the 200MHz transition frequency for medium-speed switching applications. Verify that the 50V breakdown voltage meets the circuit's operational requirements.

Part Context

This part belongs to the RN4907 series of pre-biased transistors from Toshiba. It shares the same internal transistor structure and electrical ratings as the RN4907,LF but differs in packaging format. The FE suffix often denotes automotive qualification or specific reliability standards in Toshiba's nomenclature, though verification against the datasheet is necessary.

Replacement Considerations

Direct substitutes include the RN4907,LF and RN4907,LXHF(CT from Toshiba. Other manufacturers offer equivalent dual pre-biased transistors in US6 packages, such as the BC847BS or similar NPN/PNP pairs, provided the pinout and electrical parameters match.
