Product details
Overview
BC848AW-7-F from Diodes Incorporated is an NPN small-signal transistor in SOT323 package, rated for 30 V VCEO, 100 mA IC, and 200 mW power dissipation, with DC current gain (hFE) of 110–220 at 2 mA/5 V - used in low-power switching and audio-frequency amplification stages in consumer and industrial control circuits.
For engineers reviewing the BC848AW-7-F datasheet, BC848AW-7-F pinout, BC848AW-7-F application, or BC848AW-7-F equivalent, key selection criteria include its VCEO/VCBO ratings, hFE group A specification, thermal resistance (RθJA = 625 °C/W), ESD robustness (HBM 4 kV), and SOT323 footprint compatibility with automated assembly.
Technical Context
This NPN bipolar junction transistor operates in linear amplification and saturated switching modes, with guaranteed hFE range defined under pulsed conditions (≤300 µs, ≤2% duty cycle) at VCE = 5 V and IC = 2 mA. Its fT of 100–300 MHz supports AF and low-speed digital signal handling.
The device features a complementary PNP counterpart series (BC856W–BC858W), shares identical SOT323 mechanical construction with moisture sensitivity level 1 per J-STD-020, and meets automotive change-control readiness via IATF 16949 manufacturing and AEC-Q101 qualification capability upon request.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 30 V - Maximum safe collector-emitter voltage before breakdown in common-emitter configuration. |
| IC | 100 mA continuous - Absolute max DC collector current; derates above 25°C ambient per Figure 1. |
| hFE | 110–220 @ 2 mA/5 V - Confirmed DC current gain band "A", enabling predictable biasing in amplifier designs. |
| PD | 200 mW - Max steady-state power dissipation on FR4 PCB with minimum recommended copper pad layout. |
| fT | 100–300 MHz - Gain-bandwidth product confirming suitability for audio and sub-MHz switching applications. |
| VBE(sat) | 700 mV @ 10 mA/0.5 mA - Verified base-emitter saturation voltage supporting reliable turn-on in logic-level driven switches. |
| ESD HBM | 4,000 V - Human Body Model rating ensures robustness during board handling and reflow assembly. |
Pinout & Package
Package: SOT323 - ultra-small surface-mount plastic package (2.15 mm × 2.10 mm × 0.95 mm), lead-free, halogen-free, RoHS-compliant, with matte tin-plated terminals solderable per MIL-STD-202 Method 208.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Emitter) | E | Current sink terminal; connects to ground or low-side reference in common-emitter configurations. |
| 2 (Base) | B | Control input; requires ~0.66 V forward bias and precise current limiting for stable hFE-dependent operation. |
| 3 (Collector) | C | Current source terminal; handles up to 30 V and 100 mA load, routed to VCC or active pull-up networks. |
Key Features
| Feature | Design Value |
|---|---|
| Automated insertion compatibility | SOT323 footprint and tape-and-reel packaging (3,000 pcs/reel, 7″) support high-speed pick-and-place placement. |
| Thermal performance | RθJA = 625 °C/W enables operation up to +150°C junction temperature with minimal heatsinking on standard PCBs. |
| Gain consistency | hFE binning (Group A: 110–220) ensures repeatable bias point stability across production lots. |
| Environmental compliance | Fully RoHS 3 compliant (<1000 ppm antimony, <900 ppm Br/Cl), UL 94V-0 molded compound, and J-STD-020 Level 1 moisture sensitivity. |
Applications
| LED Driver Circuit | Microcontroller GPIO Interface |
|---|---|
Use Scenario: Driving 20 mA indicator LEDs from 3.3 V or 5 V microcontroller outputs. IC Role / Device Role / Timing Role: Low-side switch with saturated VCE(sat) ≤ 250 mV at IC = 10 mA/IB = 0.5 mA. Use Value: Ensures >95% LED forward voltage utilization and eliminates GPIO current overload risk. | Use Scenario: Level-shifting and signal inversion between mixed-voltage logic domains (e.g., 1.8 V MCU to 5 V peripheral). IC Role / Device Role / Timing Role: Active inverter with propagation delay <50 ns and rail-to-rail output swing. Use Value: Maintains timing integrity in low-latency control paths without external pull-ups or complex buffers. |
| Audio Pre-amplifier Stage | Power Supply Enable Switch |
Use Scenario: First-stage amplification of microphone or sensor signals in battery-powered audio recorders. IC Role / Device Role / Timing Role: Common-emitter amplifier biased at IC = 2 mA, delivering 20 dB voltage gain with NF ≤ 10 dB. Use Value: Achieves SNR > 65 dB while consuming <1 mW quiescent power, extending battery life. | Use Scenario: Enabling/disabling auxiliary 3.3 V or 5 V rails in embedded systems using MCU-controlled enable lines. IC Role / Device Role / Timing Role: High-side or low-side power switch with IC = 100 mA capability and fast turn-off (toff < 100 ns).

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN small-signal transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC847AW-7-F | VCEO = 45 V, hFE = 110–220 (same group), fT = 100–300 MHz - higher voltage rating but identical gain and package. | Preferred where system supply exceeds 30 V but gain and footprint must match exactly. | Select when VCC > 30 V and no redesign of bias network is acceptable. |
| MMBT3904LT1G | VCEO = 40 V, hFE = 100–300 (wider spread), RθJA = 500 °C/W - tighter thermal resistance but looser hFE tolerance. | Used in cost-sensitive consumer electronics where ±20% gain variation is acceptable. | Choose for higher thermal efficiency in space-constrained layouts, accepting wider hFE variance. |
Compared with BC848AW-7-F, BC847AW-7-F offers higher voltage margin without changing gain or footprint, while MMBT3904LT1G improves thermal performance but requires gain-tolerance validation in precision bias circuits.

FAQ
What is the maximum operating temperature for BC848AW-7-F?
The BC848AW-7-F has an operating junction temperature range of –65 °C to +150 °C. Its thermal resistance (RθJA = 625 °C/W) means that at 200 mW dissipation and 25 °C ambient, junction temperature reaches 150 °C - the absolute maximum. Derating is required above 25 °C ambient per Figure 1 in DS30250 Rev. 16-2.
Is BC848AW-7-F qualified for automotive applications?
BC848AW-7-F is manufactured in IATF 16949-certified facilities and supports PPAP documentation. While not pre-qualified to AEC-Q101 out-of-box, Diodes Incorporated offers AEC-Q101 qualification upon request for automotive programs - contact your local Diodes representative to initiate change control and qualification testing.
How does the hFE group A specification affect circuit design?
Group A guarantees hFE between 110 and 220 at VCE = 5 V and IC = 2 mA, enabling deterministic bias network design. This narrow spread reduces need for trimming resistors or feedback compensation in linear amplifiers and ensures consistent saturation behavior in switching applications without overdesigning base drive.
Can BC848AW-7-F replace BC846AW-7-F in existing designs?
Yes - both share identical SOT323 package, pinout, and hFE Group A specification, but BC848AW-7-F has lower VCEO (30 V vs. 65 V) and VCBO (30 V vs. 80 V). Replacement is safe only if the application's maximum collector voltage remains ≤30 V; otherwise, BC846AW-7-F or BC847AW-7-F should be retained.
