BC817-25HE3-TP

Overview

The BC817-25HE3-TP is a single NPN silicon general-purpose bipolar junction transistor manufactured by Micro Commercial Components. It operates with a maximum collector-emitter voltage of 45 V and supports a continuous collector current of 500 mA. The device features a transition frequency of 100 MHz and a maximum power dissipation of 300 mW. It is housed in an SOT-23 surface-mount package and meets AEC-Q101 automotive qualification standards.

Feature Summary

• Automotive-grade reliability certified under the AEC-Q101 standard for robust performance in demanding environments.
• Designed for general-purpose switching and amplification applications within standard operating temperature ranges.
• Utilizes a compact SOT-23 surface-mount package to facilitate automated assembly and space-constrained circuit designs.

Applications

• General-purpose signal switching circuits
• Low-power amplifier stages
• Automotive electronic control modules

Procurement Notes

Verify the specific suffix HE3 against official datasheets to confirm lead-free compliance and RoHS status. Ensure the ordering code matches the exact electrical specifications required for the target application. Cross-reference the manufacturer part number with authorized distributor listings to validate authenticity and traceability before finalizing procurement orders.

Selection Notes

Select this component when an NPN transistor with 45 V breakdown and 500 mA current capacity is required in a small surface-mount footprint. The AEC-Q101 qualification makes it suitable for automotive systems where higher reliability thresholds are mandated compared to standard commercial grade devices.

Part Context

This part belongs to the BC817 series of NPN transistors produced by Micro Commercial Components. The series offers various voltage ratings, with the -25 variant specifically providing a 45 V collector-emitter rating. The HE3 designation indicates environmental compliance features consistent with modern manufacturing standards.

Replacement Considerations

Direct substitutes include BC817-25 from other manufacturers such as Nexperia or STMicroelectronics, provided they match the SOT-23 package and 45V/500mA electrical limits. Verify pinout compatibility and thermal characteristics before implementation.
