Product details

Overview

2N5400RLRP from onsemi is a PNP silicon general-purpose amplifier transistor in TO-92 package, rated for V_CEO = 120 V, I_C = 600 mA, and P_D = 625 mW at T_A = 25°C, with h_FE = 30–180 (at I_C = 1–50 mA), used in low-frequency linear amplification and switching circuits such as discrete audio preamplifiers and relay drivers.

For engineers reviewing the 2N5400RLRP datasheet, pinout, applications, or equivalent options, key selection considerations include its PNP polarity, TO-92 mechanical compatibility, DC current gain spread across operating current, V_CE(sat) performance at I_C/I_B = 10, and thermal derating above 25°C ambient.

Technical Context

This device operates as a medium-voltage, medium-current PNP bipolar junction transistor optimized for linear amplification and saturated switching in industrial and consumer analog circuits. Its f_T of 100–400 MHz supports stable gain up to audio frequencies, while C_obo ≤ 6.0 pF minimizes high-frequency coupling in multi-stage designs.

The 2N5400RLRP shares identical electrical specifications and TO-92 mechanical form factor with the bulk-packaged 2N5400 but is supplied in 2000-unit tape-and-reel format with Pb-free finish (RLRPG variant available). It exhibits guaranteed V_(BR)CEO ≥ 120 V and V_(BR)CBO ≥ 130 V under specified test conditions, enabling use in 100 V rail applications with margin.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	120 V - Maximum collector-emitter voltage before breakdown; enables use in 100 V supply rails with 20% safety margin.
I_C (max)	600 mA - Continuous collector current rating; supports relay coil driving and medium-power stage biasing.
h_FE range	30–180 - DC current gain variation at I_C = 1–50 mA; requires circuit tolerance for gain spread in amplifier designs.
V_CE(sat)	0.2–0.5 V - Saturation voltage at I_C/I_B = 10; ensures low conduction loss in switching applications.
f_T	100–400 MHz - Transition frequency; confirms usable bandwidth for audio and low-speed digital signal conditioning.
R_JA	200 °C/W - Junction-to-ambient thermal resistance; mandates heatsinking or airflow for >300 mW continuous dissipation.

Pinout & Package

2N5400RLRP is housed in a standard TO-92 plastic package (Case 29-11), with straight leads and Pb-free finish. Pin 1 is Emitter, Pin 2 is Base, Pin 3 is Collector - verified per onsemi marking diagram and package outline.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current sink terminal for PNP operation	Connected to higher-potential rail in common-base or common-collector configurations; defines reference for base drive.
Pin 2 (Base)	Control input for minority-carrier injection	Requires negative bias relative to emitter to forward-bias BE junction; current-limited drive essential for predictable h_FE.
Pin 3 (Collector)	Output current terminal	Typically tied to load and supply rail; reverse-biased during cutoff; handles full load current in saturation.

Key Features

Feature	Design Value
Pb-free TO-92 packaging	Complies with RoHS Directive 2011/65/EU; compatible with lead-free reflow profiles (J-STD-020).
Guaranteed V_(BR)CEO ≥ 120 V	Validated at I_C = 1.0 mA; supports reliable operation in 100 V industrial control power stages.
Low noise figure (NF ≤ 8.0 dB)	Measured at I_C = 250 μA, R_S = 1 kΩ, 1 kHz; suitable for low-level signal amplification without added noise degradation.
Thermal stability to +150°C	Junction temperature range −55°C to +150°C; enables deployment in automotive under-hood and industrial motor-control enclosures.
High f_T / low C_obo ratio	f_T ≥ 100 MHz with C_obo ≤ 6.0 pF; preserves gain-bandwidth product in multi-stage amplifier feedback loops.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP amplifier transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPSA92	V_CEO = 300 V, I_C = 500 mA, h_FE = 25–300; TO-92, same pinout	Higher voltage rating suits 200 V flyback snubbers; lower I_C limits relay coil drive capability	Select when >150 V breakdown margin required; verify layout clearance for higher voltage stress.
BC557B	V_CEO = 45 V, I_C = 100 mA, h_FE = 200–450; TO-92, same pinout	Lower voltage/current ratings; tighter h_FE binning for precision bias networks	Choose for low-power signal amplification where 120 V rating is unnecessary and gain consistency is critical.

Compared with MPSA92 and BC557B, the 2N5400RLRP delivers balanced voltage-headroom (120 V), current-drive (600 mA), and thermal robustness (T_J = +150°C) ideal for industrial analog interfaces where reliability under transient overvoltage and sustained load is prioritized over ultra-low noise or ultra-high gain.

FAQ

What is the maximum continuous collector current rating for the 2N5400RLRP?

The 2N5400RLRP has a maximum continuous collector current (I_C) rating of 600 mA at T_A = 25°C. This rating decreases linearly with ambient temperature above 25°C at 5.0 mW/°C, meaning usable current drops to approximately 400 mA at 65°C ambient. The 2N5400RLRP must be operated within this derated limit to ensure long-term reliability.

Does the 2N5400RLRP have a Pb-free finish?

Yes, the 2N5400RLRP is manufactured with a Pb-free finish compliant with RoHS Directive 2011/65/EU. This is confirmed in the onsemi ordering information table and supported by the "G" suffix option (2N5400RLRPG) indicating explicit Pb-free qualification. The 2N5400RLRP uses the same Pb-free plating process as other onsemi TO-92 devices.

What is the pin configuration of the 2N5400RLRP in TO-92 package?

The 2N5400RLRP uses standard TO-92 pinout: Pin 1 is Emitter, Pin 2 is Base, Pin 3 is Collector - verified in the onsemi datasheet's marking diagram and package outline. This matches industry-standard PNP TO-92 orientation and is identical to the 2N5401, MPSA92, and BC556 families.

Can the 2N5400RLRP replace the 2N5401 in a circuit?

The 2N5400RLRP and 2N5401 share identical TO-92 packaging and pinout but differ in polarity: 2N5400RLRP is PNP, while 2N5401 is NPN. Direct replacement is not possible without inverting the circuit topology and biasing scheme. The 2N5400RLRP cannot function as a drop-in substitute for the 2N5401 due to opposite current flow direction and voltage polarity requirements.

What is the typical transition frequency (f_T) of the 2N5400RLRP?

The 2N5400RLRP has a specified transition frequency (f_T) range of 100–400 MHz, measured at I_C = 10 mA, V_CE = 10 V, and f = 100 MHz. This indicates usable small-signal gain up to several tens of MHz, making the 2N5400RLRP appropriate for audio amplification and low-speed switching but not RF or high-speed digital applications.
