Product details

Overview

BC33716TF 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 analog and digital signal paths.

For engineers reviewing the BC33716TF datasheet, pinout, applications, or equivalent options, key selection criteria include its V_CEO/V_CES ratings, h_FE classification band (16), saturation voltage at 500 mA, thermal resistance (200 °C/W), and TO-92 mechanical compatibility with legacy through-hole PCB layouts.

Technical Context

The BC33716TF operates as a discrete bipolar junction transistor with fixed NPN polarity, optimized for linear amplification and saturated switching in ambient temperatures up to 150 °C junction temperature. Its h_FE range (100–250) and V_CE(sat) ≤ 0.7 V at I_C = 500 mA / I_B = 50 mA support reliable on/off control in driver stages.

Designed as a complement to BC327/BC328 PNP devices, it enables push-pull configurations in audio preamplifiers and low-power output stages. The TO-92 package provides standardized lead spacing (0.2 inch), straight or bent lead options, and FR-4 PCB thermal derating per JEDEC standards.

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 and switch applications.
I_C (DC)	800 mA - Continuous collector current limit; sets maximum load drive capability without thermal runaway at 25 °C ambient.
h_FE (100 mA)	100–250 - DC current gain range at V_CE = 1 V, I_C = 100 mA; determines base drive requirements for switching or bias stability in amplifiers.
V_CE(sat)	≤ 0.7 V at I_C = 500 mA, I_B = 50 mA - Low saturation voltage ensures minimal power loss and heat generation in on-state switching.
P_D	625 mW - Maximum power dissipation at 25 °C; combined with R_θJA = 200 °C/W, defines thermal headroom for board-level cooling.
f_T	100 MHz - Current-gain bandwidth product at V_CE = 5 V, I_C = 10 mA; supports small-signal amplification up to low-VHF frequencies.

Pinout & Package

BC33716TF uses the standard TO-92 3-lead plastic package with straight or bent leads, compliant with JEDEC TO-92. Lead spacing is 0.2 inch (5.08 mm); package outline matches Fairchild/ON Semiconductor mechanical drawings for BC337 series.

Pin/Terminal	Circuit Role	Design Meaning
1 (Collector)	Main current sink terminal	Connected to load or supply rail in common-emitter configuration; carries full collector current and dissipates majority of power.
2 (Base)	Control input terminal	Receives forward-biased current to turn on transistor; requires precise current limiting to avoid overdrive or thermal stress.
3 (Emitter)	Current source reference terminal	Typically tied to ground or negative rail; establishes reference for V_BE bias and defines emitter-follower or common-base operation mode.

Key Features

Feature	Design Value
h_FE classification band 16	Guaranteed 100–250 gain range enables predictable base resistor selection for consistent switching thresholds across production lots.
TO-92 tape-and-reel packaging (TFR)	Enables automated through-hole insertion in high-volume manufacturing without manual handling or orientation errors.
Complementary pairing with BC327/BC328	Supports matched push-pull output stages in Class A/B amplifiers and H-bridge drivers with symmetrical current sourcing/sinking.
JEDEC-compliant mechanical dimensions	Ensures drop-in replacement compatibility with existing TO-92 footprints, tooling, and reflow/reflow-soldering profiles.

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 (Digi-Key: BC337-16FSCT-ND)	Same h_FE band (100–250), identical TO-92 package, but supplied in bulk or ammo pack-not tape-and-reel.	No functional difference; differs only in packaging format-unsuitable for automated pick-and-place unless reel format required.	Select BC33716TF when tape-and-reel feeding is needed for SMT-compatible through-hole assembly lines.
PN2222A (ON Semi: PN2222ATFR)	Higher V_CEO (40 V vs. 45 V), lower h_FE min (100 vs. 100), same TO-92, but wider h_FE spread (100–300) and higher V_CE(sat) (0.8 V).	Acceptable in non-critical switching where tighter h_FE tolerance is not required; less suitable for precision biasing or low-loss saturation.	Choose PN2222ATFR only if BC33716TF is unavailable and design tolerates looser gain consistency and higher saturation loss.

Compared with BC337-16 and PN2222ATFR, BC33716TF offers guaranteed h_FE banding, tape-and-reel readiness, and lowest V_CE(sat) among TO-92 NPN transistors in its class-making it optimal for cost-sensitive, high-reliability through-hole switching and amplification.

FAQ

What is the h_FE range specified for BC33716TF?

The BC33716TF has a guaranteed DC current gain (h_FE) range of 100 to 250 when measured at V_CE = 1 V and I_C = 100 mA. This classification band "16" is laser-marked on the device and verified during production testing. The BC33716TF's h_FE remains stable across its operating temperature range and supports predictable base drive design in both switching and linear applications.

Does BC33716TF support automated assembly?

Yes, BC33716TF is supplied in tape-and-reel packaging (TFR suffix), specifically formatted for automated through-hole insertion equipment. Its TO-92 lead pitch (0.2 inch) and orientation markings align with industry-standard feeders and placement heads. The BC33716TF reel format eliminates manual handling, reduces orientation errors, and supports high-yield production runs without compromising mechanical or electrical integrity.

What is the maximum collector-emitter voltage rating for BC33716TF?

The BC33716TF has a maximum collector-emitter voltage rating (V_CEO) of 45 V under open-base conditions at T_A = 25 °C. Its V_CES rating is 50 V, allowing safe operation with inductive loads that generate voltage spikes. Engineers must ensure operating V_CE stays below 45 V in continuous use, and derate accordingly above 25 °C ambient per the device's thermal characteristics.

Can BC33716TF be used as a direct replacement for BC337-16?

Yes, BC33716TF is functionally and electrically identical to BC337-16, differing only in packaging format (tape-and-reel vs. bulk/ammo). Both share identical absolute maximum ratings, electrical characteristics, TO-92 footprint, and h_FE classification band 16. The BC33716TF maintains full mechanical and thermal compatibility, making it a seamless upgrade for automated assembly lines requiring reel-fed components.

What thermal derating applies to BC33716TF above 25 °C?

The BC33716TF has a thermal resistance of R_θJA = 200 °C/W and a power dissipation limit of 625 mW at 25 °C ambient. Above 25 °C, it must be derated at 5.0 mW/°C - meaning maximum allowable power drops by 5 mW for every 1 °C rise in ambient temperature. At 75 °C ambient, for example, usable power is reduced to 375 mW, requiring careful PCB layout and heatsinking for sustained operation.
