Product details

Overview

BC33716TFR from ON Semiconductor is an NPN epitaxial silicon transistor in TO-92 package, rated for 45 V V_CEO, 800 mA I_C, and 625 mW power dissipation, with DC current gain (h_FE) of 100–250 at 100 mA. It serves as a general-purpose switching and amplification device in low-power audio driver stages and small-signal control circuits.

For engineers reviewing the BC33716TFR datasheet, pinout, applications, or equivalent options, key selection criteria include its V_CEO/I_C rating, h_FE classification (16), TO-92 thermal resistance (200 °C/W), and compatibility with complementary BC327 PNP devices in push-pull configurations.

Technical Context

This transistor operates as a bipolar junction device with epitaxial base construction, optimized for linear amplification and saturated switching. Its h_FE range (100–250) and low V_CE(sat) (0.7 V at 500 mA/50 mA) support reliable on/off control in digital logic interfaces and analog signal buffering.

Thermal performance is defined by R_θJA = 200 °C/W on standard FR-4 PCBs, and maximum junction temperature is limited to 150 °C. The device is not rated for automotive or safety-critical use per manufacturer's authorized use policy.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	45 V - Maximum collector-emitter voltage before breakdown under open-base conditions; defines safe operating voltage in amplifier or switch applications.
I_C (DC)	800 mA - Continuous collector current limit; sets upper bound for load-driving capability in relay drivers or LED switches.
h_FE (100 mA)	100–250 - DC current gain at V_CE = 1 V, I_C = 100 mA; determines required base drive for target collector current.
V_CE(sat)	0.7 V - Collector-emitter saturation voltage at I_C = 500 mA, I_B = 50 mA; impacts conduction loss and heat generation in switching mode.
P_D	625 mW - Maximum power dissipation at 25 °C ambient; derates linearly at 5 mW/°C above that temperature.
f_T	100 MHz - Current gain bandwidth product at V_CE = 5 V, I_C = 10 mA; indicates usable frequency limit for small-signal amplification.

Pinout & Package

BC33716TFR is housed in a JEDEC-compliant TO-92 3-lead plastic package with straight leads, designed for through-hole mounting and manual or automated tape-and-reel assembly.

Pin/Terminal	Circuit Role	Design Meaning
1 (Collector)	Main current output terminal	Connected to load or supply rail; carries full collector current; requires thermal consideration due to power dissipation path.
2 (Base)	Control input terminal	Receives forward bias current to turn on transistor; requires current-limiting resistor to prevent overdrive and ensure stable h_FE-based operation.
3 (Emitter)	Current return path	Typically grounded or connected to low-side reference; establishes common node for biasing and signal return in common-emitter configurations.

Key Features

Feature	Design Value
h_FE classification 16	Guaranteed 100–250 DC current gain at 100 mA, enabling predictable base drive sizing in discrete amplifier and switch designs.
TO-92 package with tape-and-reel delivery	Enables automated SMT-compatible placement despite through-hole form factor, supporting high-volume production without manual handling.
Complementary pairing with BC327	Allows direct implementation of Class B or AB push-pull output stages without redesigning bias networks or layout.
150 °C max junction temperature	Supports operation in industrial ambient environments up to ~85 °C with appropriate PCB copper area and airflow.

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
BC337-16 (ON Semi, TO-92, Ammo)	Identical electrical specs and h_FE classification; differs only in packaging (ammo vs. tape-and-reel).	No functional difference; suitable for same circuit roles but requires different feeder setup in SMT lines.	Select BC33716TFR when automated pick-and-place with tape-and-reel feed is required.
PN2222A (ON Semi)	Higher V_CEO (60 V), lower h_FE min (100), same TO-92 package; f_T = 300 MHz.	Better suited for higher-voltage switching (e.g., 48 V systems); less gain consistency at low I_C.	Choose PN2222A where extended voltage headroom or higher-speed switching is needed, accepting wider h_FE variation.

Compared with BC337-16 and PN2222A, BC33716TFR offers guaranteed h_FE 100–250 in tape-and-reel format, making it optimal for volume production of cost-sensitive consumer audio and control circuits where consistent gain and automated assembly are prioritized over extreme voltage or speed.

FAQ

What is the h_FE range specified for BC33716TFR?

The BC33716TFR has a DC current gain (h_FE) range of 100 to 250 when measured at V_CE = 1 V and I_C = 100 mA. This classification "16" is guaranteed per datasheet and applies across the full operating temperature range, enabling predictable base drive design in amplifier and switching circuits using BC33716TFR.

Is BC33716TFR pin-compatible with BC337-16 or BC33725TFR?

Yes - BC33716TFR shares identical pinout (Collector-Base-Emitter, TO-92 straight lead), package dimensions, and terminal assignments with BC337-16 and BC33725TFR. However, h_FE classification differs: BC33716TFR is binned 100–250, while BC33725TFR is 160–400. Circuit performance may vary if gain-dependent biasing is used, so BC33716TFR must be verified in context.

What is the maximum power dissipation of BC33716TFR at 75°C ambient?

BC33716TFR has a rated power dissipation of 625 mW at 25°C, with a derating factor of 5.0 mW/°C above that temperature. At 75°C ambient, allowable power drops to 625 mW − (50 × 5 mW) = 375 mW. This must be respected in PCB layout with adequate copper pour and airflow to avoid exceeding 150°C junction temperature.

Can BC33716TFR replace BC33816TFR in a circuit?

No - BC33716TFR and BC33816TFR differ in absolute maximum ratings: BC33716TFR supports 45 V V_CEO and 50 V V_CES, whereas BC33816TFR is rated for only 25 V V_CEO and 30 V V_CES. Substituting BC33716TFR into a BC338-design may cause overstress if voltage exceeds 25 V, and vice versa risks breakdown. Always verify voltage margins before interchange of BC33716TFR and BC338 variants.

Does BC33716TFR meet RoHS and REACH compliance?

Yes - BC33716TFR is manufactured by ON Semiconductor and conforms to RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006. Lead-free TO-92 packaging and halogen-free molding compound are standard. Full compliance documentation, including substance declarations and test reports, is available via ON Semiconductor's quality portal for BC33716TFR.
