Diodes Incorporated BC847CDLP-7

Overview

BC847CDLP-7 from Diodes Incorporated is a dual NPN small-signal transistor in an ultra-thin X2-DFN1310-6 package (0.4 mm height), rated for 45 V V_CEO, 100 mA I_C, and offering h_FE of 420–800 at 2 mA. It delivers low V_CE(sat) (max 250 mV at I_C = 10 mA/I_B = 0.5 mA) and f_T = 100 MHz, enabling use in compact, high-density signal amplification and switching circuits in portable power management.

For engineers reviewing the BC847CDLP-7 datasheet, BC847CDLP-7 pinout, BC847CDLP-7 application, or BC847CDLP-7 equivalent, key selection criteria include its AEC-Q101 qualification, ultra-low profile packaging, dual-transistor integration in a 1.3×1.0 mm DFN, and verified performance across –65°C to +150°C operating range.

Technical Context

This dual NPN transistor integrates two independent high-gain, medium-voltage transistors in a single monolithic die within a thermally optimized X2-DFN1310-6 package. Its design supports low-power linear amplification and digital switching with tight h_FE distribution (420–800) and consistent V_BE(on) (580–770 mV) across temperature.

The device features a 357 °C/W junction-to-ambient thermal resistance on standard FR-4 PCBs and meets J-STD-020 moisture sensitivity Level 1. Its 100 MHz f_T and low C_CBO (2.0 pF) support stable RF-coupled and high-speed switching applications up to ~50 MHz.

FAQ

What is the maximum continuous collector current per transistor in BC847CDLP-7?

The absolute maximum continuous collector current (I_C) is 100 mA per transistor at T_A = +25°C, derating linearly above 25°C based on the 357 °C/W thermal resistance. At 85°C ambient, usable I_C drops to approximately 75 mA to maintain junction temperature below 150°C.

Does BC847CDLP-7 support solder reflow per JEDEC J-STD-020?

Yes - BC847CDLP-7 is rated Moisture Sensitivity Level 1 (MSL-1), meaning it may be stored indefinitely at ≤30°C/85% RH and subjected to standard Pb-free reflow profiles (peak 260°C) without baking. Its NiPdAu terminal finish ensures robust solderability per MIL-STD-202, Method 208.

How are the two transistors isolated electrically within the X2-DFN1310-6 package?

The two NPN transistors share a common silicon die but have fully isolated collector, base, and emitter terminals (pins 1–3 and 4–6). No internal connection exists between them - they operate as independent devices with matched parametric performance, confirmed by datasheet h_FE correlation plots across temperature.

Can BC847CDLP-7 replace BC847C in existing SOT-23 designs?

No - BC847CDLP-7 uses a 6-pin DFN package (X2-DFN1310-6) with different pinout and footprint than the 3-pin SOT-23 BC847C. Direct replacement requires PCB redesign. For drop-in alternatives, consider BC847CDW1T1G (SOT-363) or MMDT3904 (SOT-363), both pin-compatible with dual-transistor footprints.
