Product details
Overview
BCM847BS-7 from Diodes Incorporated is a 45V NPN matched-pair small-signal transistor in SOT363 package, featuring hFE matching (0.9–1.1), VBE matching (±2 mV), and 100 MHz fT, designed for precision current mirror, differential amplifier, and AF switching circuits in space-constrained consumer and industrial PCBs.
For engineers reviewing the BCM847BS-7 datasheet, BCM847BS-7 pinout, BCM847BS-7 application, or BCM847BS-7 equivalent, key selection criteria include dual-transistor matching tolerance, thermal resistance (625 °C/W), VCEO rating (45 V), and RoHS-compliant matte tin terminations suitable for automated SMT assembly.
Technical Context
This matched NPN pair integrates two electrically symmetric transistors on a single die within a 6-pin SOT363 package, enabling precise current mirroring and differential gain without inter-device layout mismatch. Its hFE ratio of 0.9–1.1 and VBE delta ≤ ±2 mV at IC = 2 mA are specified under identical bias conditions.
The device operates across –65°C to +150°C with 200 mW power dissipation and supports high-frequency analog functions via 100 MHz fT at VCE = 5 V, IC = 10 mA - critical for audio preamp stages and low-noise sensor interface front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - maximum safe collector-emitter voltage before breakdown in common-emitter configuration |
| hFE Matching | 0.9–1.1 - ensures <10% current gain deviation between paired transistors for stable mirror accuracy |
| VBE Matching | ±2 mV - minimizes offset error in differential pairs and precision bias networks |
| fT | 100 MHz - enables use in audio-frequency amplification and fast-switching applications up to ~10 MHz |
| RθJA | 625 °C/W - defines thermal derating slope; limits continuous power to 200 mW at TA = 25°C |
| ESD HBM | 4000 V - provides robust handling protection during board assembly and reflow |
Pinout & Package
Package: SOT363 - ultra-small 6-pin surface-mount plastic package (2.15 × 2.10 × 0.95 mm), UL 94V-0 rated, moisture sensitivity level 1, matte tin terminations solderable per MIL-STD-202.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Emitter of Transistor 1 | Low-impedance current sink node; tied to ground or bias network in mirror configurations |
| 2 | Base of Transistor 1 | Input control terminal; requires current-limited drive to avoid saturation-induced delay |
| 3 | Collector of Transistor 1 | Active output node; delivers mirrored current or amplified signal with VCEO = 45 V rating |
| 4 | Collector of Transistor 2 | Second active output; electrically isolated but thermally coupled to Pin 3 for tracking |
| 5 | Base of Transistor 2 | Independent input; enables differential bias or separate control of second transistor |
| 6 | Emitter of Transistor 2 | Second low-impedance sink; used for balanced emitter-coupled logic or dual-mirror topologies |
Key Features
| Feature | Design Value |
|---|---|
| Matched hFE ratio | 0.9–1.1 at VCE = 5 V, IC = 2 mA - reduces gain error in current mirrors below 10% |
| VBE matching tolerance | ±2 mV at same bias - lowers DC offset in differential amplifiers and improves CMRR |
| Thermal coupling | Monolithic die integration - ensures <1°C junction temperature difference between transistors during operation |
| Automated insertion compatibility | SOT363 footprint with 0.65 mm pitch - supports high-speed pick-and-place and reflow profiling |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar matched-pair transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847BPDW1T1G | Same VCEO (45 V) and hFE range (200–450), but hFE matching not specified; SOT-363 package | Lacks guaranteed matching - unsuitable for precision current mirrors or differential amplifiers requiring <10% gain error | Select only when matching is non-critical and cost is primary constraint |
| MBT3904DW1T1G | Lower VCEO (40 V), no VBE or hFE matching spec; higher fT (300 MHz) | Better high-frequency response but no matching - appropriate for RF switching, not analog precision circuits | Choose for RF or digital switching where matching is irrelevant and speed is prioritized |
Compared with BC847BPDW1T1G and MBT3904DW1T1G, BCM847BS-7 uniquely guarantees both hFE and VBE matching on a monolithic die, making it the only option among the three qualified for precision analog functions like current mirrors and low-drift differential amplifiers.

FAQ
What is the maximum operating temperature for BCM847BS-7?
The BCM847BS-7 has an operating junction temperature range of –65°C to +150°C, with thermal resistance RθJA = 625 °C/W. At ambient temperatures above 25°C, power dissipation must be linearly derated per Figure 1 in the datasheet to maintain safe junction temperature.
Does BCM847BS-7 support automotive qualification?
BCM847BS-7 itself is not AEC-Q101 qualified; however, Diodes offers automotive-grade variants (e.g., BCM847BSQ-7) that meet AEC-Q101 requirements and are manufactured in IATF 16949-certified facilities. Standard BCM847BS-7 is intended for industrial and consumer applications.
How is pin identification oriented on the SOT363 package?
With the marking side up and the tab (notch) facing left, pins are numbered counterclockwise starting from the bottom-left corner: Pin 1 (E1), Pin 2 (B1), Pin 3 (C1), Pin 4 (C2), Pin 5 (B2), Pin 6 (E2). This matches the top-view schematic in DS41216 Rev. 2–2.
Can BCM847BS-7 be used in linear amplifier configurations?
Yes - its 100 MHz fT, low VCE(sat) (≤100 mV), and matched characteristics make it suitable for Class-A audio preamplifier stages and low-noise sensor interface amplifiers, provided biasing remains within the 200 mW power limit and VCE ≤ 45 V.
