Product details
Overview
BC846UE6327 from Infineon Technologies is a dual NPN silicon small-signal transistor array in SOT-363 (SC-74) package, featuring two galvanically isolated transistors with matched hFE (200–450), VCEO = 65 V, and low VCE(sat) (90–250 mV at IC = 10 mA). It is designed for AF input stages and driver applications in compact analog signal paths.
For engineers reviewing the BC846UE6327 datasheet, BC846UE6327 pinout, BC846UE6327 application, or BC846UE6327 equivalent, key selection criteria include dual-transistor matching, AEC-Q101 qualification for automotive use, thermal resistance (RthJS ≤ 130 K/W), fT = 250 MHz, and RoHS-compliant Pb-free packaging.
Technical Context
This dual NPN array integrates two electrically isolated transistors on a single die with tightly controlled parameter matching-especially hFE, VBE(sat), and VCE(sat)-enabling balanced differential amplification or push-pull switching without external matching components. Its SOT-363 footprint supports high-density PCB layouts while maintaining thermal performance up to Tj = 150 °C.
The device operates across –65 °C to +150 °C storage and junction temperature ranges, with maximum ratings including IC = 100 mA per transistor, Ptot = 250 mW (TS ≤ 118 °C), and VCBO = 80 V. AC characteristics confirm suitability for audio-frequency and low-MHz signal conditioning with Ccb = 0.95 pF and noise figure F = 10 dB at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 65 V - Supports rail-to-rail operation in 48 V and lower automotive/industrial supply domains. |
| hFE (IC = 2 mA) | 200–450 - Enables stable biasing and predictable gain in amplifier and switch driver designs. |
| VCE(sat) (IC = 10 mA) | 90–250 mV - Minimizes conduction loss in low-voltage switching and current-source circuits. |
| fT | 250 MHz - Ensures adequate bandwidth for audio preamplifiers and low-speed digital interface buffering. |
| RthJS | ≤130 K/W - Allows direct thermal path design from junction to solder point in thermally constrained layouts. |
| Ccb | 0.95 pF - Limits Miller effect in common-emitter configurations up to mid-MHz frequencies. |
| AEC-Q101 Qualified | Yes - Validated for automotive electronics requiring reliability under temperature cycling and humidity stress. |
Pinout & Package
SOT-363 (SC-74) surface-mount package: 6-pin, dual-row, gull-wing leads; 2.0 mm × 2.1 mm footprint; 1.1 mm max height; RoHS-compliant matte tin plating.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (E1) | Emitter of TR1 | Low-impedance output node for first transistor; referenced to ground or bias network. |
| 2 (B1) | Base of TR1 | Control input for TR1; requires current-limited drive due to VBE(on) ≈ 0.58–0.77 V. |
| 3 (C2) | Collector of TR2 | Active output node for second transistor; connects to load or next-stage input. |
| 4 (E2) | Emitter of TR2 | Independent emitter terminal enabling separate biasing or current sensing for TR2. |
| 5 (B2) | Base of TR2 | Isolated control input; enables independent switching or differential pair configuration. |
| 6 (C1) | Collector of TR1 | Primary output node for TR1; shares no internal connection with TR2 collector. |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual NPN transistor array applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BE6327 | VCEO = 45 V (vs. 65 V); hFE min = 250; identical SOT-363 package and pinout. | Limited to ≤36 V systems; unsuitable for 48 V automotive subsystems requiring higher breakdown margin. | Select when lower VCEO suffices and tighter hFE distribution is prioritized. |
| MMDT3904-7-F | Single-die dual NPN but non-matched hFE; VCEO = 40 V; RthJS = 150 K/W (vs. 130 K/W). | Higher thermal resistance limits power handling in continuous-duty drivers; no guaranteed matching. | Choose only for cost-sensitive, non-matching applications where thermal headroom exceeds 20 K/W. |
Compared with BC846UE6327, BC847BE6327 trades breakdown voltage for higher minimum hFE, while MMDT3904-7-F sacrifices matching and thermal performance for broader distributor availability-making BC846UE6327 optimal for AEC-Q101–compliant, matched dual-transistor functions.

FAQ
Is BC846UE6327 pin-compatible with BC846BE6327?
Yes-both share identical SOT-363 (SC-74) package and pin assignment (E1-B1-C2-E2-B2-C1). However, BC846BE6327 has hFE = 110–220 (lower gain range) and lacks AEC-Q101 qualification, making it unsuitable for automotive applications despite mechanical compatibility.
What is the maximum continuous collector current per transistor?
The absolute maximum continuous collector current is 100 mA per transistor at TS ≤ 118 °C. Derating applies above this case temperature; at 125 °C case temperature, maximum IC drops to approximately 75 mA based on the Ptot vs. TS curve in the datasheet.
Can BC846UE6327 be used in linear amplifier configurations?
Yes-it is characterized for linear operation with specified hFE, VBE(ON), and noise figure (F = 10 dB at 1 kHz). Its low Ccb and stable hFE vs. IC support Class-A and AB audio preamplifier designs up to 20 kHz bandwidth.
Does the device require external emitter resistors for stability in differential pair use?
No-emitter degeneration is optional. The matched hFE and VBE between TR1 and TR2 allow stable differential operation without emitter resistors; however, adding 10–100 Ω resistors improves common-mode rejection and thermal stability in high-precision current mirrors.
