Product details
Overview
BC846DS,115 from Nexperia is a dual NPN general-purpose transistor pair in SOT457 (TSOP6) package, rated for 65 V VCEO, 100 mA IC, and featuring matched hFE (200–450), low VCE(sat) (max 300 mV at IC=100 mA), and AEC-Q101 qualification - used in compact automotive signal switching and biasing circuits.
For engineers reviewing the BC846DS,115 datasheet, BC846DS,115 pinout, BC846DS,115 application, or BC846DS,115 equivalent, key selection criteria include dual-transistor matching tolerance, thermal resistance (Rth(j-a) = 328 K/W per device), SC-74 footprint compatibility, and automotive-grade reliability validation.
Technical Context
The BC846DS,115 integrates two electrically isolated NPN transistors in a single TSOP6 package, eliminating mutual interference while enabling space-efficient complementary-stage or push-pull configurations. Each transistor supports VCEO = 65 V, IC = 100 mA continuous, and operates across −55 °C to +150 °C ambient.
Its design emphasizes low parasitic capacitance (Cc = 1.9 pF typ, Ce = 11 pF typ) and high fT (100 MHz min), supporting stable small-signal amplification up to mid-VHF range. The AEC-Q101 qualification confirms suitability for automotive body electronics under thermal cycling and humidity stress.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Maximum safe collector-emitter voltage with base open; defines high-side switch headroom in 24 V automotive systems. |
| IC | 100 mA - Continuous DC collector current per transistor; sufficient for LED drivers, relay coils, and logic-level interface loads. |
| hFE | 200–450 @ VCE=5 V, IC=2 mA - Tight DC current gain spread enables predictable biasing without individual trimming. |
| VCE(sat) | 200–300 mV @ IC=100 mA, IB=5 mA - Low saturation voltage minimizes power loss and self-heating in switching applications. |
| Cc | 1.9 pF typ @ VCB=10 V - Low collector-base capacitance reduces Miller effect, improving high-frequency stability in amplifier stages. |
| Rth(j-a) | 328 K/W per device on FR4 PCB - Thermal resistance determines junction temperature rise under 250 mW dissipation; critical for derating in enclosed modules. |
| AEC-Q101 | Qualified - Confirmed reliability for automotive use including temperature cycling, HAST, and mechanical shock per AEC standard. |
Pinout & Package
SOT457 (TSOP6) plastic surface-mount package: 6-pin, 1.3 mm pitch, 3.1 × 1.7 mm footprint, 0.95 mm height, with pin 1 index marker. Designed for reflow soldering per IPC-J-STD-020.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | E1 (Emitter of TR1) | Current sink node for first transistor; connects to ground or low-side load return path. |
| 2 | B1 (Base of TR1) | Control input for TR1; requires ~0.7 V forward bias and current limiting resistor for saturation. |
| 3 | C2 (Collector of TR2) | Current source node for second transistor; connects to supply rail or active load in totem-pole configuration. |
| 4 | E2 (Emitter of TR2) | Current sink node for TR2; electrically isolated from E1 - enables independent bias networks. |
| 5 | B2 (Base of TR2) | Independent control input for TR2; no coupling to B1 - supports asynchronous switching. |
| 6 | C1 (Collector of TR1) | Current source node for TR1; paired with C2 for dual-output drive or differential sensing. |
Key Features
| Feature | Design Value |
|---|---|
| Closely matched hFE | Both transistors exhibit 200–450 gain range at same test conditions - simplifies differential pair or current mirror design without binning. |
| No mutual interference | Electrically isolated die structure prevents crosstalk between TR1 and TR2 - essential for noise-sensitive analog front-ends. |
| Low VCE(sat) | ≤300 mV at full 100 mA load - reduces conduction loss by >40% vs. legacy general-purpose transistors, extending battery life in portable ECUs. |
| AEC-Q101 qualification | Validated for automotive underhood environments including 1000-hr HTOL, -40/+125 °C thermal cycling, and 85 °C/85% RH bias HAST. |
| Small SOT457 footprint | 3.1 × 1.7 mm area - saves >60% board space vs. two discrete SOT23 devices, enabling denser PCB layouts in ADAS sensor modules. |
Applications
| Automotive Door Module Switching | Industrial PLC Input Conditioning |
|---|---|
|
Use Scenario: Driving window lift motor relays and door lock solenoids in 12 V/24 V vehicle architectures. IC Role / Device Role / Timing Role: Dual NPN switch providing isolated low-side control for two independent loads with shared microcontroller GPIO. Use Value: Eliminates need for two separate SOT23 transistors and associated passives, reducing BOM count and assembly cost by 35%. |
Use Scenario: Converting 24 V industrial field signals (e.g., proximity sensors) to 3.3 V/5 V logic-compatible levels for FPGA or MCU inputs. IC Role / Device Role / Timing Role: Level-shifting buffer with hysteresis-capable bias network using matched gain transistors for noise immunity. Use Value: Matched hFE ensures consistent threshold behavior across channels, reducing calibration effort in multi-channel I/O modules. |
| LED Driver for Dashboard Backlight | USB Port Over-Current Protection |
|
Use Scenario: Constant-current dimming of white LED strings in automotive instrument clusters using PWM-controlled emitter-follower stage. IC Role / Device Role / Timing Role: High-linearity NPN current source with low VCE(sat) minimizing dropout voltage at 80 mA per channel. Use Value: 200 mV typical VCE(sat) enables full brightness down to 3.0 V supply - critical for cold-cranking operation. |
Use Scenario: Implementing auto-resetting current limit for USB 2.0 downstream ports in infotainment head units. IC Role / Device Role / Timing Role: Dual-transistor foldback limiter where TR1 senses current and TR2 disables upstream FET gate during overcurrent. Use Value: Isolated terminals prevent latch-up during fault events; AEC-Q101 rating ensures robustness against load dump transients. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847DS,115 | Higher hFE range (300–630), otherwise identical pinout, ratings, and package. | Better suited for low-drive applications (e.g., microcontroller GPIO directly driving base without resistor). | Select when higher current gain is required to reduce base drive current below 100 µA. |
| MBT3904DW1T1G | Same SOT363 package but lower VCEO (40 V), higher VCE(sat) (max 400 mV), and no AEC-Q101 qualification. | Limited to non-automotive 5 V/12 V logic interfaces; not suitable for 24 V automotive loads. | Choose only for cost-sensitive consumer-grade designs where automotive qualification is unnecessary. |
Compared with BC846DS,115, BC847DS,115 offers higher gain for reduced base current demand, while MBT3904DW1T1G sacrifices voltage rating and automotive reliability for lower unit cost in non-critical applications.

FAQ
What is the maximum allowable junction temperature for BC846DS,115?
The absolute maximum junction temperature (Tj) is 150 °C, as defined in the Absolute Maximum Ratings table. Operation above this temperature risks permanent degradation of current gain and leakage characteristics. Derating is required above 25 °C ambient per the 328 K/W Rth(j-a) curve.
Can BC846DS,115 be used in linear amplifier configurations?
Yes - its fT of 100 MHz and low noise figure (3.1 dB at 1 kHz) support small-signal amplification up to ~10 MHz. However, it is not optimized for RF power; use is limited to low-power audio preamps or sensor signal conditioning with VCE ≤ 12 V and IC ≤ 10 mA.
Is the SOT457 package compatible with standard SMT reflow profiles?
Yes - the BC846DS,115 meets JEDEC J-STD-020D moisture sensitivity level 1 and is qualified for lead-free reflow up to 260 °C peak. Recommended profile uses ramp rate ≤ 3 °C/s, soak at 150–200 °C for 60–120 s, and peak time within 217–220 °C for ≤ 60 s.
How does the AEC-Q101 qualification impact design validation?
AEC-Q101 certification confirms the device has passed accelerated stress tests including HTOL, temperature cycling, and HAST - eliminating need for duplicate qualification testing in automotive programs. It validates reliability for 15-year service life in under-hood environments per ISO/TS 16949 requirements.
