Product details

Overview

2N5400RLRPG 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. It delivers h_FE = 30–180 (at I_C = 1–50 mA), V_CE(sat) ≤ 0.5 V (I_C = 50 mA, I_B = 5 mA), and f_T = 100–400 MHz - used in low-power linear amplification and switching circuits in industrial control and signal conditioning modules.

For engineers reviewing the 2N5400RLRPG datasheet, pinout, applications, or equivalent options, key selection criteria include verified PNP polarity, TO-92 mechanical compatibility, DC current gain consistency across temperature (−55°C to +150°C), saturation voltage under defined drive conditions, and Pb-free tape-and-reel packaging compliance for automated assembly.

Technical Context

This discrete PNP bipolar junction transistor operates in active, saturation, and cutoff regions with specified breakdown voltages: V_(BR)CEO = 120 V (I_C = 1 mA), V_(BR)CBO = 130 V (I_C = 100 µA), and V_(BR)EBO = 5.0 V (I_E = 10 µA). Its thermal resistance R_JA = 200°C/W confirms suitability for ambient-limited PCB layouts without heatsinking.

Small-signal parameters include h_fe = 30–200 (I_C = 1 mA, f = 1 kHz), C_obo ≤ 6.0 pF (V_CB = 10 V), and NF ≤ 8.0 dB (I_C = 250 µA, R_S = 1 kΩ). Switching performance is characterized by t_on, t_off, and storage time under defined test conditions (V_CC = 30–120 V, I_C/I_B = 10).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	120 V - Maximum collector-emitter voltage before breakdown under open-base condition; defines safe operating voltage headroom in high-side switch or amplifier stages.
I_C (continuous)	600 mA - Continuous collector current rating at 25°C ambient; derates linearly above 25°C per 5.0 mW/°C.
h_FE range	30–180 - DC current gain at I_C = 1–50 mA and V_CE = 5 V; supports predictable biasing in Class-A amplifiers and saturated switches.
V_CE(sat)	≤ 0.5 V at I_C = 50 mA, I_B = 5 mA - Low saturation voltage minimizes power loss and heating in switching applications.
f_T	100–400 MHz - Transition frequency at I_C = 10 mA, V_CE = 10 V; enables use in RF preamplifier and broadband signal amplification up to ~100 MHz.
R_JA	200°C/W - Junction-to-ambient thermal resistance; determines required PCB copper area or airflow for thermal management at full power.

Pinout & Package

2N5400RLRPG is housed in a TO-92 plastic package (Case 29-11), with straight leads and Pb-free finish. Dimensions comply with JEDEC TO-92 standard: body height ~4.7 mm, lead pitch 1.27 mm, and total length ~4.7 mm. Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (viewed with flat side facing user, leads down).

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Emitter)	Current exit terminal for PNP device	Connected to higher potential node in common-base or common-collector configurations; sets reference for base bias network.
Pin 2 (Base)	Control electrode for minority-carrier injection	Receives forward-biased current to modulate collector current; requires series resistor to limit I_B and ensure saturation or linear operation.
Pin 3 (Collector)	Current entry terminal for PNP device	Typically tied to supply rail in high-side switch; voltage swing capability limited by V_CEO and load impedance.

Key Features

Feature	Design Value
Pb-free TO-92 packaging	Meets RoHS Directive 2011/65/EU; compatible with lead-free reflow profiles (peak 260°C) and automated tape-and-reel pick-and-place.
Wide operating temperature range	−55°C to +150°C junction temperature enables deployment in automotive engine compartments and industrial motor controls.
Low leakage currents	I_CBO ≤ 100 nA at 100 V and 25°C; ensures stable cutoff state in battery-powered sensor interfaces and standby circuits.
Controlled h_FE binning	Guaranteed minimum h_FE = 30 at I_C = 1 mA supports reliable bias design without individual device screening.

Equivalent & Alternatives

The following parts are listed as comparable options for similar PNP general-purpose transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
MPSA92	V_CEO = 300 V, I_C = 500 mA, h_FE = 50–250 - higher voltage rating but lower current and tighter gain spread.	Better suited for high-voltage analog switches and flyback snubbers where 120 V margin is insufficient.	Select MPSA92 only when V_CEO > 120 V is mandatory; verify layout clearance for 300 V creepage.
BC557B	V_CEO = 45 V, I_C = 100 mA, h_FE = 200–450 - lower voltage/current but higher and narrower gain range.	Preferred for low-power, high-gain signal amplification in battery-operated devices with < 30 V rails.	Choose BC557B for space-constrained designs needing tighter h_FE tolerance; avoid in >45 V or >100 mA applications.

Compared with MPSA92 and BC557B, the 2N5400RLRPG offers balanced voltage-current-gain trade-offs (120 V/600 mA/30–180) in a widely supported TO-92 footprint, making it optimal for mid-range industrial switching and linear amplification where neither extreme voltage nor ultra-low power dominates design requirements.

FAQ

What is the maximum junction temperature for the 2N5400RLRPG?

The 2N5400RLRPG has a specified operating and storage junction temperature range of −55°C to +150°C. This allows deployment in harsh environments such as under-hood automotive modules or industrial motor drives. Thermal design must ensure that power dissipation (P_D = 625 mW at 25°C, derating 5.0 mW/°C) does not exceed this limit under worst-case ambient and self-heating conditions. The 2N5400RLRPG datasheet confirms R_JA = 200°C/W for standard PCB mounting.

Is the 2N5400RLRPG pin-compatible with the 2N5401?

No, the 2N5400RLRPG is not pin-compatible with the 2N5401. While both are TO-92 packaged PNP transistors, the 2N5401 is rated for V_CEO = 160 V and exhibits different h_FE and V_CE(sat) characteristics. Their pinouts match (Emitter-Base-Collector), but electrical substitution requires validation of voltage margin, gain, and saturation behavior in the target circuit. The 2N5400RLRPG datasheet does not list the 2N5401 as a direct replacement.

Does the 2N5400RLRPG support lead-free reflow soldering?

Yes, the 2N5400RLRPG is a Pb-free device and qualified for lead-free reflow soldering per J-STD-020. Its marking includes the "G" suffix (as in 2N5400RLRPG) indicating RoHS-compliant packaging. Peak reflow temperature must not exceed 260°C, and thermal profile must comply with JEDEC standards for TO-92 packages. The 2N5400RLRPG product documentation references the ON Semiconductor Soldering and Mounting Techniques Reference Manual for process guidance.

What is the typical noise figure of the 2N5400RLRPG in small-signal amplification?

The 2N5400RLRPG has a maximum noise figure of 8.0 dB at I_C = 250 µA, V_CE = 5.0 V, R_S = 1.0 kΩ, and f = 1.0 kHz. This value applies to low-frequency audio and sensor signal amplification where noise performance impacts signal-to-noise ratio. The 2N5400RLRPG datasheet specifies this as a guaranteed maximum, not a typical value, and actual noise may vary with bias point and external components.

Can the 2N5400RLRPG be used in switching power supply feedback circuits?

The 2N5400RLRPG can be used in optocoupler-driven feedback paths of isolated DC-DC converters, provided its V_CEO = 120 V and switching speed meet the loop bandwidth and isolation voltage requirements. Its f_T = 100–400 MHz supports response up to several hundred kHz, but designers must validate propagation delay, storage time, and saturation behavior under actual load conditions. The 2N5400RLRPG is not optimized for high-frequency PWM gate driving.
