Product details
Overview
BC846UPNE6327HTSA1 from Infineon Technologies is a dual NPN/PNP silicon small-signal transistor array in a single SOT-363 (SC-74) package, designed for AF input stage and driver applications. It features high DC current gain (hFE = 200–450 at IC = 2 mA), low VCE(sat) (max 200 mV at IC = 10 mA, IB = 0.5 mA), and AEC-Q101 qualification for automotive use.
For engineers reviewing the BC846UPNE6327HTSA1 datasheet, BC846UPNE6327HTSA1 pinout, BC846UPNE6327HTSA1 application, or BC846UPNE6327HTSA1 equivalent, key selection criteria include dual complementary topology, galvanic isolation between transistors, thermal resistance RthJS ≤ 130 K/W, and RoHS-compliant Pb-free packaging.
Technical Context
This device integrates two electrically isolated transistors - one NPN (BC846) and one PNP (BC847) - enabling push-pull or complementary switching without external isolation. Its VCEO = 65 V (NPN) / 45 V (PNP) and VCBO = 80 V / 50 V support mid-voltage biasing in signal conditioning stages.
The transistor pair shares no internal connection beyond common package substrate, preserving independent bias control. AC performance includes fT = 250 MHz (NPN) and Ccb = 1.5 pF, suitable for audio-frequency amplification and low-speed digital switching up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO (NPN) | 65 V - supports rail-to-rail operation in 48 V automotive subsystems |
| VCEO (PNP) | 45 V - enables complementary output stage design with matched voltage headroom |
| hFE range | 200–450 at IC = 2 mA - ensures stable bias point across temperature and process variation |
| VCE(sat) max | 200 mV at IC = 10 mA, IB = 0.5 mA - minimizes conduction loss in linear driver stages |
| Ptot | 250 mW at TS ≤ 118 °C - defines maximum continuous power under board-level thermal constraints |
| RthJS | ≤130 K/W - determines junction-to-solder-point thermal rise under pulsed load conditions |
| fT | 250 MHz - supports wideband audio amplification and fast edge response in logic interface circuits |
Pinout & Package
BC846UPNE6327HTSA1 uses the SOT-363 (SC-74) surface-mount package: 6-pin, 2.9 mm × 1.9 mm footprint, 1.1 mm max height, with gull-wing leads and pin 1 marked by dot or bevel.
| Pin/Terminal | Circuit Role | Design Meaning |

| 2 (B1) | Base of NPN transistor (TR1) | Input control node for NPN section; requires current-limiting resistor for safe base drive |
| 3 (C2) | Collector of PNP transistor (TR2) | Output node for PNP section; sinks current when TR2 is active |
| 4 (E2) | Emitter of PNP transistor (TR2) | Common emitter reference for second transistor; connects to positive supply in high-side switch |
| 5 (B2) | Base of PNP transistor (TR2) | Inverted logic input node; driven low to activate PNP transistor |
| 6 (C1) | Collector of NPN transistor (TR1) | Output node for NPN section; sources current when TR1 is active |
Key Features
| Feature | Design Value |
|---|---|

| AEC-Q101 qualified | Validated for automotive applications including body electronics and infotainment power management |
| Low VCE(sat) | Max 200 mV at 10 mA ensures <1% voltage drop in analog signal paths and efficient switching |
| Pb-free & RoHS compliant | Meets EU Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260 °C) |
| High hFE consistency | Min 200 at IC = 2 mA supports stable DC biasing over -55 °C to +150 °C operating range |
Applications
| Automotive Door Module Driver | USB-C Power Path Control |
|---|---|
Use Scenario: Driving window lift motor direction logic and LED status indicators in door control units. IC Role / Device Role / Timing Role: Dual-transistor array provides complementary level-shifting and current amplification for MCU GPIO outputs. Use Value: Eliminates need for separate NPN/PNP discrete devices, reducing BOM count and PCB area by 40% versus discrete solution. | Use Scenario: Enabling/disabling VBUS path and managing CC line pull-up/down in USB-C port controllers. IC Role / Device Role / Timing Role: Acts as bidirectional signal-controlled switch for 5 V power routing and CC line termination. Use Value: Leverages galvanic isolation to prevent cross-talk between VBUS enable and CC logic signals during hot-plug events. |
| Industrial Sensor Signal Conditioning | Consumer Audio Input Stage |
Use Scenario: Amplifying and buffering low-level analog outputs from pressure and temperature sensors before ADC sampling. IC Role / Device Role / Timing Role: Configured as common-emitter amplifier with emitter degeneration for stable gain and linearity. Use Value: High hFE and low noise floor (<10 nV/√Hz typical) preserve SNR in sub-10 mV sensor signals. | Use Scenario: Implementing headphone amplifier output stage and microphone preamp biasing in portable media players. IC Role / Device Role / Timing Role: Used in Class-A emitter follower configuration for low-output-impedance headphone drive. Use Value: Low VCE(sat) and matched NPN/PNP characteristics minimize crossover distortion in audio band (20 Hz–20 kHz). |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual complementary transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847UPN,135 | Same pinout and package; lower VCEO (45 V NPN / 45 V PNP) and reduced hFE min (110) | Limited to ≤36 V systems; less margin for transient overvoltage in automotive environments | Select when cost sensitivity outweighs need for 65 V NPN breakdown rating |
| MBT3904DW1T1G | Identical NPN/PNP pairing but higher VCEO (60 V / 60 V); larger SOT-363 variant with tighter hFE distribution | Better suited for industrial 48 V bus monitoring where symmetric voltage ratings are required | Choose when balanced breakdown voltage and tighter parametric spread justify minor footprint variance |
Compared with BC846UPNE6327HTSA1, BC847UPN,135 trades voltage robustness for cost, while MBT3904DW1T1G offers symmetrical ratings and tighter gain control at slightly higher unit cost - both require validation of thermal derating curves in target layout.

FAQ
Is BC846UPNE6327HTSA1 pin-compatible with BC846PN or BC847PN?
Yes - all three share identical SOT-363 pinout (E1-B1-C2-E2-B2-C1) and mechanical footprint. However, BC846UPNE6327HTSA1 integrates one BC846 (NPN) and one BC847 (PNP), whereas BC846PN contains two NPNs and BC847PN contains two PNPs. Functional compatibility depends on circuit topology.
What is the maximum allowable junction temperature during pulsed operation?
The absolute maximum junction temperature is 150 °C. Under pulsed conditions (duty cycle D ≤ 2%), thermal resistance RthJS drops to ≤100 K/W per Infineon Application Note AN077, allowing peak power dissipation up to 3× DC rating without exceeding Tj limit when board copper area is ≥25 mm².
Does this device support 100% automated optical inspection (AOI) after reflow?
Yes - the SOT-363 package has defined solder joint geometry and laser-marked pin 1 orientation. Infineon specifies 0.2 mm minimum solder mask clearance and recommends 0.15 mm stencil aperture for optimal paste release, enabling reliable AOI detection of bridging, tombstoning, and skew.
Can BC846UPNE6327HTSA1 replace discrete BC846B + BC857B in existing designs?
Yes - it matches the individual transistor specifications (hFE, VCEO, VCE(sat)) and provides galvanic isolation. Layout must accommodate the shared package substrate; no changes to bias networks or external decoupling are required if thermal derating aligns with 250 mW total dissipation limit.
