Product details

Overview

BC847RAZ from Nexperia is a dual NPN general-purpose transistor pair in a DFN1412-6 (SOT1268) package, rated for 45 V V_CEO, 100 mA I_C, and AEC-Q101 qualified for automotive use. It integrates two matched NPN transistors in one ultra-thin (0.47 mm height), leadless surface-mount device optimized for space-constrained mobile and automotive control circuits.

For engineers reviewing the BC847RAZ datasheet, BC847RAZ pinout, BC847RAZ application, or BC847RAZ equivalent, this page delivers verified pin assignments, thermal derating curves, DC current gain (h_FE = 200–450 at I_C = 2 mA), saturation voltage (V_CEsat ≤ 300 mV at I_C = 100 mA), and AEC-Q101 qualification status - all critical for high-reliability discrete selection.

Technical Context

The BC847RAZ implements two independent NPN bipolar junction transistors sharing a common thermal die in a single DFN1412-6 package. Each transistor supports V_CEO = 45 V, I_C = 100 mA continuous, and I_CM = 200 mA peak with h_FE specified across –55 °C to +150 °C ambient.

Its AEC-Q101 qualification confirms robustness against automotive stress tests including HTOL, temperature cycling, and ESD (HBM ≥ 2 kV). Thermal resistance is R_th(j-a) = 261 K/W per device on FR4 PCB - enabling stable operation up to T_j = 150 °C under defined layout conditions.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum collector-emitter voltage before breakdown; defines safe switching range in 24 V automotive loads.
I_C	100 mA - Continuous collector current per transistor; supports signal-level switching and low-power amplification.
h_FE	200–450 - DC current gain at V_CE = 5 V, I_C = 2 mA; enables predictable base drive sizing for digital logic interfacing.
V_CEsat	≤300 mV - Collector-emitter saturation voltage at I_C = 100 mA, I_B = 5 mA; ensures low conduction loss in saturated-switch applications.
P_tot (per device)	480 mW - Total power dissipation on FR4 PCB; sets thermal design margin for dual-transistor operation without forced cooling.
f_T	100 MHz - Transition frequency at V_CE = 5 V, I_C = 10 mA; supports audio-frequency amplification and fast digital switching.
AEC-Q101	Qualified - Validated for automotive use per Stress Test Qualification for Discrete Semiconductors; includes HTOL, TC, HAST, and ESD testing.

Pinout & Package

DFN1412-6 (SOT1268) is a 6-terminal, leadless, ultra-thin plastic package measuring 1.4 mm × 1.2 mm × 0.47 mm with exposed thermal pad. Its low profile (0.5 mm max height) and small footprint support high-density PCB layouts in portable and automotive modules.

Pin	Circuit Role	Design Meaning
1	E1	Emitter of Transistor 1 - Common reference node for TR1; requires low-impedance connection to ground or bias network.
2	B1	Base of Transistor 1 - Input control terminal for TR1; driven by logic-level or analog signal sources.
3	C2	Collector of Transistor 2 - Output node for TR2; connects to load or next-stage input with voltage headroom up to 45 V.
4	E2	Emitter of Transistor 2 - Common reference node for TR2; may be tied to E1 or independently biased.
5	B2	Base of Transistor 2 - Independent control input for TR2; enables dual-channel switching or differential pair configuration.
6	C1	Collector of Transistor 1 - Primary output node for TR1; shares thermal path with C2 and internal die substrate.

Key Features

Feature	Design Value
Dual NPN integration	Reduces board area by ~40% vs. two discrete SOT23 transistors; eliminates separate placement and soldering steps.
0.47 mm body height	Enables stacking under shields or in ultra-thin enclosures; compatible with automated optical inspection (AOI) due to planar top surface.
AEC-Q101 qualification	Validates reliability for under-hood automotive modules (e.g., body control units, sensor interfaces) without additional qualification effort.
Thermal-enhanced DFN	261 K/W junction-to-ambient resistance on FR4 allows 480 mW total dissipation - sufficient for dual 100 mA switching at 25 °C ambient.
Matched h_FE tracking	Both transistors share same die, ensuring consistent DC gain across temperature (±15% typical mismatch at 25 °C).

IC Role / Device Role / Timing Role: Dual NPN configured as active-low optocoupler drivers and voltage translators.

Use Value: V_CEO = 45 V withstands industrial surge standards (IEC 61000-4-5); h_FE > 200 ensures reliable saturation with 10 kΩ base resistors.

Use Scenario: Enabling/disabling V_BUS paths and managing CC line pull-ups in a USB-C port controller subsystem.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual NPN transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC847BPDW1T1G	SO-8 package; higher P_tot = 500 mW; h_FE = 200–450 (same grade); not AEC-Q101 qualified.	Preferred for non-automotive industrial designs requiring easier rework or higher power margin.	Select when thermal headroom >480 mW is needed and AEC-Q101 is not required.
MBT3904DW1T1G	SOT-363 package; V_CEO = 40 V; h_FE = 100–300; AEC-Q101 qualified; lower f_T = 300 MHz (but higher than BC847RAZ).	Used where higher f_T is critical and 40 V rating suffices (e.g., 3.3 V/5 V logic interface).	Choose for RF-adjacent signal conditioning where transition frequency outweighs voltage rating.

Compared with BC847BPDW1T1G and MBT3904DW1T1G, the BC847RAZ uniquely combines AEC-Q101 qualification, 45 V rating, and 0.47 mm height in DFN1412-6 - making it optimal for space- and reliability-critical automotive modules where thermal density and transient immunity are prioritized over reworkability or raw speed.

FAQ

What is the maximum junction temperature and how is it maintained?

The BC847RAZ has a maximum junction temperature (T_j) of 150 °C. This limit is maintained through its DFN1412-6 package thermal resistance of 261 K/W (per device on FR4 PCB), allowing 480 mW total dissipation at 25 °C ambient. Derating follows the curve in Figure 1: power must decrease linearly above 25 °C ambient to keep T_j ≤ 150 °C.

Is the BC847RAZ pinout compatible with standard dual-transistor packages like SOT-363?

No - BC847RAZ uses a proprietary DFN1412-6 (SOT1268) pinout: Pin 1=E1, Pin 2=B1, Pin 3=C2, Pin 4=E2, Pin 5=B2, Pin 6=C1. This differs from SOT-363 (which uses 1=B1, 2=E1, 3=C1, 4=C2, 5=E2, 6=B2) and is not mechanically or electrically interchangeable without PCB redesign.

How does the AEC-Q101 qualification impact design validation?

AEC-Q101 qualification means BC847RAZ has passed accelerated stress tests including 1000-hour HTOL at 150 °C, 1000-cycle temperature cycling (–40 °C to +125 °C), and HBM ESD ≥ 2 kV. This eliminates need for customer-level reliability requalification in automotive applications, reducing time-to-market and test cost for Tier 1 suppliers.

Can BC847RAZ replace discrete BC847B transistors in existing designs?

Yes, functionally - but only with PCB layout revision. The BC847RAZ integrates two BC847B-equivalent transistors (h_FE 200–450, V_CEO 45 V) in one DFN1412-6 package, whereas discrete BC847B uses SOT-23. Footprint, thermal path, and pinout differ significantly; direct drop-in replacement is not possible without modifying land patterns and routing.
