Product details
Overview
BC81716MTF from ON Semiconductor is an NPN epitaxial silicon transistor in SOT-23 package, rated for 45 V VCEO, 800 mA IC, and 310 mW power dissipation, with hFE of 100–250 at IC = 100 mA; used in low-power switching and AF-driver stages.
For engineers reviewing the BC81716MTF datasheet, pinout, applications, or equivalent options, this page delivers verified electrical parameters, thermal behavior, SOT-23 terminal mapping, and validated alternative transistors for discrete BJT selection in cost-sensitive consumer and industrial signal control circuits.
Technical Context
This device operates as a general-purpose NPN bipolar junction transistor optimized for linear amplification and saturated switching. Its 45 V collector-emitter breakdown voltage and 100–250 DC current gain (hFE) support reliable operation in low-voltage logic interfacing and audio preamplifier stages.
Thermal resistance of 403 °C/W and junction temperature limit of 150 °C define its derating envelope under continuous DC bias; output capacitance of 12 pF and fT of 100 MHz confirm suitability for audio-frequency and low-speed digital switching up to ~10 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VCEO | 45 V - Maximum safe collector-emitter voltage before avalanche breakdown in common-emitter configuration. |
| IC (DC) | 800 mA - Continuous collector current handling capacity without thermal runaway at TA = 25°C. |
| hFE | 100–250 - Confirmed DC current gain range at VCE = 1 V, IC = 100 mA, enabling predictable base drive sizing. |
| VCE(sat) | 0.7 V max at IC = 500 mA, IB = 50 mA - Low saturation voltage ensures minimal conduction loss in switch-mode operation. |
| fT | 100 MHz - Current gain bandwidth product confirming usable small-signal amplification up to audio and low RF frequencies. |
| Cob | 12 pF at VCB = 10 V - Output junction capacitance limiting high-frequency response and affecting switching speed. |
Pinout & Package
SOT-23 (JEDEC TO-236AB) 3-lead surface-mount package with standard pin assignment: Pin 1 = Base, Pin 2 = Emitter, Pin 3 = Collector.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (Base) | Control input terminal | Receives forward-biased current to modulate collector current; requires series resistor for stable biasing in switching applications. |
| 2 (Emitter) | Current return path | Common reference node for both base and collector; grounded in common-emitter configuration to enable voltage amplification. |
| 3 (Collector) | Output current terminal | Delivers amplified or switched load current; connected to supply rail via load in typical low-side switch topology. |
Key Features
| Feature | Design Value |
|---|---|
| Complementary pair availability | Paired with BC807 series PNP transistors for push-pull amplifier and H-bridge driver designs. |
| Low VCE(sat) at high IC | 0.7 V max at 500 mA enables efficient switching in battery-powered logic-level interfaces and LED drivers. |
| Stable hFE classification | 16-grade binning (100–250) ensures consistent gain matching across production lots for analog gain-setting circuits. |
| JEDEC-standard SOT-23 footprint | Enables drop-in replacement in legacy designs and compatibility with automated pick-and-place assembly systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar NPN general-purpose transistor applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BC817-16-7-F (Diodes Inc.) | Identical hFE bin (100–250), same SOT-23 package, but VCEO = 45 V and VCBO = 50 V match BC81716MTF exactly. | No functional deviation; validated for same switching and amplification roles in consumer electronics PCBs. | Select when sourcing from Diodes Inc. authorized channels; pinout and thermal performance fully aligned. |
| MMBT3904LT1G (ON Semiconductor) | Lower hFE (100–300), same VCEO = 40 V (vs. 45 V), higher fT = 300 MHz, but lower IC = 200 mA. | Not suitable for 500 mA switching loads; better for high-speed, low-current signal routing than power switching. | Choose only for signal conditioning where bandwidth >100 MHz matters more than current drive capability. |
Compared with BC81716MTF, BC817-16-7-F offers identical electrical and mechanical specifications for seamless substitution, while MMBT3904LT1G trades current capacity for higher frequency response-making it unsuitable for high-IC switching but viable for fast digital signal buffering.

FAQ
What is the maximum collector current rating for BC81716MTF?
The BC81716MTF has a maximum continuous DC collector current (IC) rating of 800 mA at TA = 25°C. Derating applies above 25°C at 2.48 mW/°C, and actual usable current depends on PCB layout, ambient temperature, and thermal management. The BC81716MTF must not exceed this limit to avoid permanent junction damage.
Does BC81716MTF have a specified hFE range, and how is it binned?
Yes, BC81716MTF is hFE-binned to the "16" grade, meaning its DC current gain falls within 100–250 at VCE = 1 V and IC = 100 mA. This binning ensures predictable base drive requirements in production designs and is confirmed in the official Fairchild/ON Semiconductor datasheet Rev. 1.1.0.
What is the pin configuration of BC81716MTF in the SOT-23 package?
The BC81716MTF uses standard SOT-23 pinout: Pin 1 is Base, Pin 2 is Emitter, and Pin 3 is Collector. This matches JEDEC TO-236AB specification and is identical across all BC817/BC818 variants. No alternate pinouts exist for this part number.
Can BC81716MTF replace BC817-16 in existing designs?
Yes, BC81716MTF is functionally and mechanically identical to BC817-16, differing only in packaging suffix ("MTF" denotes tape-and-reel). Both share identical electrical specs, SOT-23 footprint, pinout, and hFE binning. The BC81716MTF is a direct replacement for BC817-16 in automated assembly environments.
What is the thermal resistance (RθJA) of BC81716MTF, and how does it affect PCB design?
The BC81716MTF has a junction-to-ambient thermal resistance (RθJA) of 403 °C/W under JEDEC-standard FR-4 board conditions (76 mm × 114 mm, minimum land pattern). This value means each watt of dissipated power raises junction temperature by 403°C above ambient-so PCB copper area and airflow must be sized accordingly to keep TJ ≤ 150°C.
