BC517RL1G

Single Bipolar Transistors Overview

The BC517RL1G is an NPN Darlington transistor manufactured by onsemi, housed in a TO-92 plastic package for through-hole mounting. It features a maximum collector-emitter voltage of 30 V and a maximum collector current of 500 mA. The device guarantees a minimum DC current gain (hFE) of 30,000. Electrical characteristics include a maximum collector-base voltage of 40 V, a maximum emitter-base voltage of 10 V, and a maximum collector-emitter saturation voltage of 1 V at specified currents. Power dissipation is rated at 625 mW, with an operating temperature range from -50 °C to +150 °C.

Single Bipolar Transistors Feature Summary

• High DC current gain capability suitable for applications requiring significant signal amplification
• Robust thermal performance allowing operation up to a junction temperature of 150 °C
• Integrated Darlington configuration providing high sensitivity with low input drive requirements

Single Bipolar Transistors Applications

• General-purpose amplification circuits requiring very high gain
• Switching applications for low-power loads
• Driver stages in audio or sensor interface designs

Single Bipolar Transistors Procurement Notes

Verify the specific ordering suffix RL1G against the manufacturer's current datasheet to confirm packaging and reel specifications. Ensure the component meets RoHS compliance requirements for your target market. Cross-reference the part number with official onsemi documentation to validate pinout assignments and absolute maximum ratings before finalizing procurement orders.

Single Bipolar Transistors Selection Notes

Select this component when circuit design demands a single NPN device with exceptionally high current gain rather than discrete transistor pairs. The TO-92 package is appropriate for prototyping and low-volume through-hole assemblies. Consider the 625 mW power dissipation limit and thermal management needs when designing for continuous operation near maximum ratings.

Single Bipolar Transistors Part Context

This part belongs to the BC517 family of NPN Darlington transistors produced by onsemi. It serves as the complementary counterpart to the PNP BC516 series. The device is designed for general-purpose use where high amplification factors are critical, offering a compact solution compared to multi-transistor configurations.

Single Bipolar Transistors Replacement Considerations

Compatible substitutes include the BC517 from other manufacturers such as NXP Semiconductors or Motorola, provided pinouts and electrical limits match. Verify that alternative sources offer equivalent hFE minimums and thermal characteristics.
