Product details

Overview

BD14016S from Fairchild Semiconductor is a PNP epitaxial silicon transistor in TO-126 package, rated for -80 V V_CEO, -1.5 A continuous collector current, and 12.5 W case power dissipation at T_C=25°C, used in medium-power linear amplification and switching circuits such as audio output stages and relay drivers.

For engineers reviewing the BD14016S datasheet, pinout, applications, or equivalent options, key selection factors include its h_FE classification (100–250 at I_C = -150 mA), V_CE(sat) of -0.5 V at I_C = -500 mA / I_B = -50 mA, and safe operating area defined for pulsed and DC operation up to 150°C junction temperature.

Technical Context

This device operates as a medium-power PNP bipolar junction transistor with fixed emitter-base and collector-base junction structures optimized for linear gain stability and switching robustness. Its h_FE is specified across three test conditions (I_C = -5 mA, -0.5 A, -150 mA), supporting both small-signal amplification and power switching roles.

The BD14016S exhibits V_CEO(sus) = -80 V under I_C = -30 mA / I_B = 0, ICBO ≤ -0.1 µA at V_CB = -30 V, and thermal derating begins at T_C > 25°C with 0.1 W/°C reduction in P_C, enabling predictable thermal management in PCB-mounted heatsink applications.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-80 V - Maximum allowable collector-emitter voltage before breakdown in common-emitter configuration
I_C (DC)	-1.5 A - Continuous collector current rating defining steady-state power handling capability
P_C (T_C=25°C)	12.5 W - Maximum power dissipation at case temperature 25°C, requiring heatsink for full-load operation
h_FE (I_C = -150 mA)	100–250 - DC current gain range determining base drive requirements for saturation or linear bias
V_CE(sat)	-0.5 V @ I_C = -500 mA / I_B = -50 mA - Low saturation voltage enabling efficient switching with minimal conduction loss
T_J	150 °C - Maximum junction temperature limit governing thermal design margin and reliability lifetime

Pinout & Package

BD14016S uses the TO-126 plastic package with integrated metal tab for mechanical mounting and thermal conduction. Pin 1 is Emitter, Pin 2 is Collector, Pin 3 is Base - the collector is internally connected to the metal tab for direct heatsinking.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Current exit path for PNP operation	Connected to most negative potential in circuit; base-emitter forward bias enables conduction
2 (Collector)	Current entry path and primary heat sink interface	Internally bonded to metal tab; must be electrically isolated from chassis unless common ground required
3 (Base)	Control terminal for minority-carrier injection	Requires negative current relative to emitter to turn on; h_FE-dependent drive sizing critical

Key Features

Feature	Design Value
High V_CEO rating	-80 V supports operation in 48 V and higher industrial supply rails without cascading or clamping
Classified h_FE bin (16)	Guaranteed h_FE = 100–250 at I_C = -150 mA ensures consistent base drive design across production lots
Low V_CE(sat)	-0.5 V minimizes power loss during saturated switching, improving efficiency in relay and lamp drivers
TO-126 thermal design	Metal tab enables direct mounting to heatsinks with thermal resistance as low as 2.5°C/W (junction-to-case)

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BD140	Same die, identical electrical specs; BD14016S denotes h_FE bin 16 (100–250), while BD140 may be unbinned or lower-bin	No functional difference in circuit operation; binning improves predictability of base drive design	Select BD14016S when guaranteed h_FE range is required for production consistency
MJD127	TO-252 (DPAK) package, -100 V V_CEO, -2 A I_C, h_FE = 30–240; higher voltage/current but surface-mount only	Requires PCB redesign for SMT layout and thermal pad; not drop-in compatible with through-hole TO-126 footprint	Choose MJD127 only when upgrading to SMT or needing extended voltage margin beyond -80 V

Compared with BD140 (unbinned) and MJD127 (SMT), BD14016S offers guaranteed high-gain binning in through-hole TO-126, simplifying thermal and drive design for medium-power linear and switching applications without layout change.

FAQ

What is the h_FE range guaranteed for BD14016S?

The BD14016S is binned to h_FE = 100–250 when measured at V_CE = -2 V and I_C = -150 mA. This classification (bin "16") ensures predictable base current requirements across production units, unlike generic BD140 parts which may fall outside this range. BD14016S maintains this specification under standard test conditions per Fairchild's Rev. A datasheet.

Is BD14016S pin-compatible with BD139 or BD137?

No - BD14016S is a PNP transistor in TO-126 package (Emitter-Collector-Base pinout), while BD139 and BD137 are NPN complements. They share the same TO-126 outline and mechanical footprint, but polarity and pin assignment differ. BD14016S pairs specifically with BD139 in complementary amplifier designs, not as a direct replacement.

What is the maximum safe continuous collector current for BD14016S?

The BD14016S has a rated DC collector current of -1.5 A at T_C = 25°C. Operation above this value requires derating based on case temperature: P_C decreases by 0.1 W/°C above 25°C. At T_C = 75°C, maximum I_C drops to approximately -1.0 A to maintain safe junction temperature below 150°C.

Does BD14016S require a heatsink in typical applications?

Yes - BD14016S dissipates up to 12.5 W at T_C = 25°C, but its thermal resistance from junction to case is ~2.5°C/W. Without a heatsink, ambient temperature rise would exceed safe limits even at moderate power. A properly mounted aluminum heatsink (≥10 cm² surface area) is recommended for any application drawing >0.5 A continuously or pulsed above 1 A.

Can BD14016S replace BD140 in existing designs?

Yes - BD14016S is functionally identical to BD140 except for guaranteed h_FE binning (100–250). It shares the same absolute maximum ratings, pinout, package, and electrical characteristics. If the original design used BD140 and achieved acceptable performance, BD14016S will operate identically while offering tighter gain consistency across units.
