Product details

Overview

BD13616S from Fairchild Semiconductor is a PNP epitaxial silicon transistor in TO-126 package, rated for -45 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 applications such as audio output stages and relay drivers.

For engineers reviewing the BD13616S datasheet, pinout, applications, or equivalent options, key selection criteria include confirmed h_FE classification (100–250 at I_C = -150 mA), V_CE(sat) ≤ -0.5 V at I_C = -500 mA/I_B = -50 mA, junction temperature limit of 150°C, and TO-126 mechanical compatibility with heatsink mounting.

Technical Context

This PNP bipolar junction transistor operates in active, saturation, and cutoff regions with DC current gain (h_FE) specified across three test conditions: 25–250 (I_C = -5 mA to -150 mA), enabling stable biasing in both linear and switching modes. Its safe operating area (SOA) supports pulsed operation up to -3.0 A with 2% duty cycle and 350 µs pulse width.

V_CEO(sus) matches V_CEO at -45 V under I_C = -30 mA/I_B = 0, confirming ruggedness against transient overvoltage. Base-emitter on-voltage is -1.0 V at I_C = -0.5 A, supporting direct TTL/CMOS interface with appropriate base drive.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	-45 V - Maximum sustainable 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 - Case-referenced thermal power limit requiring heatsink for full-load operation
h_FE3	100–250 - DC current gain at V_CE = -2 V, I_C = -150 mA, critical for low-base-drive switching designs
V_CE(sat)	≤ -0.5 V - Saturation voltage at I_C = -500 mA/I_B = -50 mA, determining conduction loss in switch mode
T_J	150°C - Maximum allowable junction temperature, constraining thermal design margin
V_EB0	-5 V - Emitter-base reverse voltage limit, relevant for protection diode integration

Pinout & Package

BD13616S uses the TO-126 package: molded plastic case with metal tab for heatsink attachment, 3-pin through-hole configuration, and standardized footprint per JEDEC TO-126 outline.

Pin/Terminal	Circuit Role	Design Meaning

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
BD136G	Same electrical specs; RoHS-compliant green molding compound and lead finish	No functional change; required for modern environmental compliance programs	Select BD136G when RoHS/REACH conformance is mandatory and legacy BD13616S is unavailable
MJD127	Higher V_CEO (-100 V), same I_C (-1.5 A), TO-252 surface-mount package	Requires PCB redesign; suited for higher-voltage industrial controls where space is constrained	Choose MJD127 only if system voltage exceeds 60 V or SMT assembly is required

Compared with BD13616S, BD136G offers identical performance with updated environmental compliance, while MJD127 trades through-hole convenience for higher voltage rating and surface-mount form factor-neither is pin-compatible without layout revision.

FAQ

What is the h_FE classification for BD13616S?

The BD13616S is classified as h_FE3 = 100–250, measured at V_CE = -2 V and I_C = -150 mA. This classification ensures predictable current gain in mid-current switching applications and simplifies base resistor calculation for microcontroller-driven loads. The BD13616S datasheet confirms this range under standard test conditions.

Is BD13616S pin-compatible with BD136 or BD138?

Yes, BD13616S shares the same TO-126 package and pinout (Emitter-Collector-Base) as BD136 and BD138, but differs in h_FE classification and absolute maximum ratings: BD13616S matches BD136's -45 V V_CEO and -45 V V_CBO, not BD138's -60 V ratings. Substitution requires verification of voltage margin in the target circuit.

What is the maximum pulsed collector current for BD13616S?

The BD13616S supports I_CP = -3.0 A under pulsed conditions defined as 350 µs pulse width and 2% duty cycle. This rating is validated by the device's Safe Operating Area (SOA) curve and enables short-duration surge handling in motor startup or solenoid actuation. Exceeding these conditions risks thermal runaway.

Does BD13616S require a heatsink in normal operation?

Yes, BD13616S requires a heatsink when dissipating more than ~1.25 W continuously, as its P_C drops from 12.5 W at T_C = 25°C to 1.25 W at T_A = 25°C. For example, at I_C = -1.0 A and V_CE = -1.2 V, power dissipation reaches 1.2 W-near the ambient-rated limit-so even modest loads benefit from thermal management.

Can BD13616S be used as a direct replacement for BD136 in existing designs?

Yes, BD13616S is functionally and mechanically identical to BD136, sharing -45 V V_CEO, TO-126 package, and E-C-B pinout. Its h_FE classification (100–250) falls within BD136's broader 40–100 range, offering improved gain consistency. No PCB changes are needed, and BD13616S maintains full compatibility with legacy BD136 designs.
