RN1905FE,LXHF(CT

Overview

The RN1905FE,LXHF(CT is a pre-biased dual NPN transistor array manufactured by Toshiba Semiconductor and Storage. It integrates two NPN transistors with built-in bias resistors in a compact surface-mount package. The device features a collector-emitter breakdown voltage of 50V and a continuous collector current of 100mA. Internal resistors are configured with R1 at 2.2 kΩ and R2 at 47 kΩ. It operates within a junction temperature range up to 150°C and has a maximum power dissipation of 200mW.

Feature Summary

• Dual NPN configuration with integrated base and emitter resistors for simplified circuit design
• High-speed switching capability supported by a transition frequency of 250MHz
• Automotive-grade reliability certified under AEC-Q101 standards

Applications

• General-purpose switching circuits requiring dual independent control
• Logic level translation interfaces between different voltage domains
• Driver stages for low-current loads in automotive electronic systems

Procurement Notes

Verify the specific ordering suffix against official Toshiba documentation to confirm packaging type and compliance status. Ensure the component matches the required AEC-Q101 qualification if used in automotive applications. Cross-reference the manufacturer part number with authorized distributor listings to confirm authenticity and current production status before procurement.

Selection Notes

Select this component when space-constrained designs require two matched NPN switches with fixed biasing. The integrated resistor network reduces external component count compared to discrete solutions. Verify that the 100mA current rating and 50V voltage limits align with the target application's electrical requirements.

Part Context
