Product details
Overview
BCM847BS from Nexperia is an AEC-Q101-qualified NPN/NPN matched double transistor in SOT363-3 (SC-88) package, featuring hFE matching ratio ≥0.9, VBE matching ≤2 mV, and 45 V VCEO per transistor-designed for precision current mirroring and differential amplification in automotive sensor signal conditioning circuits.
For engineers reviewing the BCM847BS datasheet, BCM847BS pinout, BCM847BS application, or BCM847BS equivalent, key selection criteria include matched hFE tolerance, base-emitter voltage tracking at 2 mA/5 V, thermal resistance (416 K/W per device), and TSSOP6 footprint compatibility with reflow-only assembly.
Technical Context
This dual NPN transistor integrates two fully isolated silicon epitaxial planar transistors on a single die with tightly controlled process matching. Its design enables simultaneous operation under identical bias conditions while maintaining <2 mV VBE mismatch and ≥0.9 hFE1/hFE2 ratio at 25 °C.
The device operates within −65 °C to 150 °C ambient range, supports 100 mA continuous collector current per transistor, and delivers 100–250 MHz transition frequency (fT) at IC = 10 mA-optimized for low-noise analog front-ends requiring stable gain and offset performance across temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V maximum-supports rail-to-rail operation in 3.3 V and 5 V analog supply domains without saturation risk |
| hFE matching | ≥0.9 (min)-ensures ≤10% current gain deviation between transistors for accurate mirror ratio control |
| VBE matching | ≤2 mV (max)-enables sub-0.1% input offset error in differential pair configurations |
| Ptot (per device) | 300 mW-allows dual-transistor operation at full rated current with FR4 PCB mounting |
| fT | 100–250 MHz-supports high-frequency small-signal amplification up to audio and low-speed RF bands |
| Rth(j-a) | 416 K/W-defines thermal derating limit of ~0.72 °C/mW for ambient-limited power handling |
| AEC-Q101 | Qualified-certified for automotive underhood applications including engine control and cabin sensors |
Pinout & Package
SOT363-3 (SC-88/TSSOP6) surface-mount plastic package with 0.65 mm lead pitch, 2.2 mm × 1.35 mm body, and reflow-only soldering requirement per Nexperia specification.

| 2 | B1 | Base of Transistor 1-bias input for TR1; matched to B2 for symmetrical drive |
| 3 | C2 | Collector of Transistor 2-output node for TR2; electrically isolated from C1 |
| 4 | E2 | Emitter of Transistor 2-shared or independent emitter connection depending on circuit topology |
| 5 | B2 | Base of Transistor 2-matched to B1 for balanced differential input response |
| 6 | C1 | Collector of Transistor 1-primary output node for TR1; used as reference or active load |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched NPN transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BCM857BS | PNP/PNP complement-identical matching specs but opposite polarity | Required where complementary current sourcing or level-shifting is needed | Select when building complementary mirror pairs or PNP-input differential stages |
| BC847BS | Unmatched version-no guaranteed hFE or VBE tracking between transistors | Suitable only for non-critical dual-transistor functions like discrete logic or switching | Choose only if matching is not required and cost sensitivity outweighs precision needs |
Compared with BCM857BS and BC847BS, the BCM847BS uniquely delivers verified NPN/NPN matching for analog accuracy-making it irreplaceable in current mirrors and differential amplifiers where offset and gain tracking directly impact measurement fidelity.

FAQ
Is BCM847BS pin-compatible with BC847BS?
Yes-BCM847BS uses identical SOT363-3 pinout and footprint as BC847BS, enabling drop-in replacement in existing layouts. However, only BCM847BS guarantees hFE and VBE matching; BC847BS provides no matching specification and must be validated per unit if used in precision circuits.
What is the maximum allowable junction temperature during operation?
The absolute maximum junction temperature (Tj) is 150 °C. At ambient temperatures up to 125 °C, power dissipation must be limited to ≤120 mW per transistor (based on Rth(j-a) = 625 K/W) to maintain safe thermal margin per IEC 60134 limiting values.
Can BCM847BS be used in wave soldering processes?
No-Nexperia explicitly specifies reflow soldering as the only recommended method. Wave soldering is not qualified and may cause internal delamination or parametric shift due to thermal stress exceeding package design limits per Figure 13 footprint notes.
How is hFE matching defined in the datasheet?
hFE matching is defined as the ratio of the smaller hFE value to the larger hFE value (hFE1/hFE2 or hFE2/hFE1), with minimum 0.9. This metric ensures predictable current transfer in mirror topologies regardless of which transistor serves as reference or output leg.
