Overview
The BCV46QTA is a PNP Darlington transistor manufactured by Diodes Incorporated, designed for automotive applications. It features a collector-emitter breakdown voltage (BVCEO) of -60V and a continuous collector current (IC) of -500mA. The device offers a high static forward current transfer ratio (hFE) exceeding 10,000 at IC = -100mA and VCE = -5V. Electrical characteristics include a collector-base breakdown voltage (BVCBO) of -80V and an emitter-base breakdown voltage (BVEBO) of -10V. The transition frequency (fT) is typically 200MHz. Power dissipation is rated at 310mW in still air on a minimum FR4 PCB, with an operating temperature range from -55°C to +150°C.
Feature Summary
- Qualified to AEC-Q101 standards for high reliability in automotive environments
- High DC current gain (hFE > 10k @ 100mA) suitable for sensitive switching applications
- Totally lead-free, fully RoHS compliant, and halogen/antimony free
Applications
- Automotive electronic circuits requiring high-gain switching
- General-purpose amplification stages
- Driver circuits for loads up to 500mA
Procurement Notes
Verify the specific ordering suffix 'QTA' against official Diodes Incorporated documentation to confirm automotive qualification status. Ensure that the required packaging quantity matches the standard reel size of 3,000 units per 7-inch tape width. Confirm compliance with PPAP requirements if mandated by your supply chain protocols before finalizing procurement.
Selection Notes
Select the BCV46QTA when automotive-grade reliability and high current gain are required. This component serves as the complementary PNP type to the BCV47 NPN Darlington transistor. Consider the -60V collector-emitter voltage rating and -500mA continuous current limit during circuit design. Verify thermal management needs based on the specified power dissipation ratings under your specific PCB layout conditions.
Part Context
The BCV46 series consists of PNP Darlington transistors in a SOT-23 package. The BCV46QTA variant is specifically designated for automotive use, meeting AEC-Q101 qualification standards. It shares electrical and thermal characteristics with the standard BCV46TA, differing primarily in its automotive certification and potential PPAP capability. The series provides a compact solution for high-gain switching applications.
Replacement Considerations
Publicly confirmed substitute part numbers include BCV46TA (standard grade), BCV46E6327HTSA1 (Infineon), and BCV46-QR (Nexperia). Verify pinout compatibility and ensure that alternative manufacturers meet the same AEC-Q101 qualification if automotive reliability is required.
