Product details

Overview

BD13916S from Fairchild Semiconductor is an NPN epitaxial silicon transistor in TO-126 package, rated for 80 V V_CEO, 1.5 A continuous collector current, and 12.5 W collector dissipation at T_C = 25°C, used in medium-power linear amplification and switching applications such as audio output stages and power supply control circuits.

For engineers reviewing the BD13916S datasheet, pinout, applications, or equivalent options, key selection criteria include V_CEO/V_CBO rating, hFE classification (100–250), saturation voltage at 500 mA/50 mA drive, thermal derating behavior, and complementary pairing with BD140.

Technical Context

This device operates as a medium-power bipolar junction transistor optimized for linear and switching use where robust DC gain stability and low V_CE(sat) are required. Its hFE3 classification (100–250 at V_CE = 2 V, I_C = 150 mA) and guaranteed V_CE(sat) ≤ 0.5 V at I_C = 500 mA / I_B = 50 mA support reliable biasing in Class AB amplifier outputs and relay drivers.

The BD13916S shares the same TO-126 mechanical outline and terminal assignment (Emitter–Collector–Base) as BD135/BD137 variants but is distinguished by its 80 V breakdown ratings and hFE3 binning. Junction temperature limit of 150°C and safe operating area curves define its thermal boundary under pulsed and continuous operation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	80 V - Maximum sustainable collector-emitter voltage before breakdown; defines usable rail voltage headroom in switching designs.
I_C (DC)	1.5 A - Continuous collector current capability; sets maximum steady-state load current in driver or amplifier stages.
P_C (T_C=25°C)	12.5 W - Thermal power limit at case temperature 25°C; requires heatsinking for sustained high-current operation.
hFE3	100–250 - DC current gain at V_CE = 2 V, I_C = 150 mA; ensures predictable base drive requirements in linear bias networks.
V_CE(sat)	≤ 0.5 V @ I_C = 500 mA, I_B = 50 mA - Low saturation voltage minimizes conduction loss and self-heating in switching applications.
T_J	150°C - Maximum junction temperature; determines thermal design margin and heatsink sizing for reliability.

Pinout & Package

BD13916S is housed in a TO-126 plastic package with standardized lead configuration: Pin 1 = Emitter, Pin 2 = Collector, Pin 3 = Base. The package features a metal tab (collector-connected) for mechanical mounting and thermal conduction to heatsinks.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current exit path for majority carriers	Connected to ground or low-side reference; forms return path in common-emitter configurations.
2 (Collector)	Current entry path; electrically tied to metal tab	Mounted to heatsink; requires electrical isolation if heatsink is grounded; defines primary power path.
3 (Base)	Control electrode for minority carrier injection	Driven by resistor-limited current source; gain-dependent base current determines collector conduction level.

Key Features

Feature	Design Value
High V_CEO/V_CBO rating	80 V enables use in 48 V industrial supplies and higher-voltage audio rails without derating.
hFE3 classification (100–250)	Ensures consistent gain across production lots for stable bias point setting in linear amplifiers.
Low V_CE(sat) (≤0.5 V)	Reduces power loss and thermal stress in saturated switching, improving efficiency in relay and lamp drivers.
TO-126 package with collector-tab	Provides direct thermal path to heatsink while maintaining low-cost through-hole assembly compatibility.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN medium-power transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BD139G	Same V_CEO/I_C/hFE3 specs; ON Semiconductor rebranded version with identical TO-126 pinout and thermal profile.	No functional difference; qualified for same linear and switching roles including audio output and relay driving.	Select BD139G when sourcing from ON Semi distribution channels; fully interchangeable with BD13916S in layout and bias design.
MJE13003	Higher V_CEO (400 V), lower hFE (min 10), larger TO-220 package; not pin-compatible.	Suited for flyback switchers and high-voltage SMPS, not audio linearity-critical applications.	Choose MJE13003 only for high-voltage switching where BD13916S lacks sufficient breakdown margin; requires PCB redesign.

Compared with BD13916S, BD139G offers identical electrical and mechanical performance with alternate branding, while MJE13003 trades gain and linearity for higher voltage capability and different thermal packaging-making it unsuitable as a drop-in replacement but viable for distinct high-voltage applications.

FAQ

What is the pin configuration of BD13916S?

The BD13916S uses a standard TO-126 package with three leads: Pin 1 is Emitter, Pin 2 is Collector (connected to the metal tab), and Pin 3 is Base. This configuration is consistent across the BD135/137/139 series and verified in Fairchild's Rev. A datasheet Figure "Package Dimensions" and terminal assignment note.

Is BD13916S suitable for audio amplifier output stages?

Yes, BD13916S is specifically intended for medium-power linear applications including audio output stages. Its hFE3 classification (100–250), low V_CE(sat), and 80 V V_CEO support clean Class AB operation when paired with BD140 in push-pull configurations, as confirmed in the "Applications" section of the BD135/137/139 datasheet.

What is the maximum continuous collector current for BD13916S?

The maximum continuous collector current (I_C) for BD13916S is 1.5 A at case temperature T_C = 25°C. At elevated temperatures, this rating must be reduced per the power derating curve shown in Figure 5 of the datasheet, with full derating to zero at T_C = 150°C.

Does BD13916S have a complementary PNP transistor?

Yes, BD13916S is explicitly designated as complementary to BD140 in the "Applications" section of the datasheet. Both share matching voltage ratings, gain ranges, and TO-126 packaging, enabling balanced push-pull operation in amplifiers and H-bridge drivers.

What is the typical DC current gain (hFE) of BD13916S at 150 mA collector current?

The BD13916S is binned to hFE3 classification, specifying a DC current gain range of 100–250 at V_CE = 2 V and I_C = 150 mA. This value is documented in the "Electrical Characteristics" table under hFE3 parameter and applies directly to BD13916S per the hFE classification legend.
