Product details

Overview

PN2369A from NXP Semiconductors (formerly Philips) is an NPN silicon switching transistor in TO-92 (SOT54/SC-43A) package, rated for 15 V V_CEO, 200 mA I_C, and 500 mW P_tot, with 500 MHz f_T and sub-10 ns turn-on time - used in high-speed digital logic interfaces and pulse amplification stages.

For engineers reviewing the PN2369A datasheet, PN2369A pinout, PN2369A application, or PN2369A equivalent, key selection considerations include its low V_CE(sat) (≤200 mV at I_C=10 mA/I_B=1 mA), tight h_FE range (40–120), and thermal resistance of 250 K/W - critical for compact through-hole switching designs requiring fast edge control and stable gain at 25 °C ambient.

Technical Context

The PN2369A employs a planar epitaxial base structure optimized for low storage time (t_s ≤10 ns) and fast transition frequency (f_T = 500 MHz), enabling reliable operation in pulse-width modulation drivers and TTL-compatible buffer stages. Its V_BE(sat) of 700–850 mV at I_C=10 mA/I_B=1 mA supports direct interfacing with 3.3 V and 5 V logic families without level-shifting.

Designed for DC and pulsed switching up to 100 MHz, it features low collector capacitance (C_c = 4 pF at V_CB=5 V) and tightly specified switching times: t_on ≤10 ns, t_off ≤20 ns. The device operates across −65 °C to +150 °C junction temperature with I_CBO ≤400 nA at 25 °C.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	15 V - maximum safe collector-emitter voltage under open-base condition; defines rail limit for low-voltage switch applications.
I_C (DC)	200 mA - continuous collector current handling; suitable for driving small relays, LEDs, or logic gate inputs.
f_T	500 MHz - transition frequency at V_CE=10 V, I_C=10 mA; enables stable gain in RF predriver and broadband amplifier roles.
t_on/t_off	8–10 ns / 10–20 ns - measured between 10%–90% levels; supports >50 MHz digital clock distribution and pulse shaping.
V_CE(sat)	≤200 mV at I_C=10 mA/I_B=1 mA - ensures minimal conduction loss and efficient power delivery in saturated-switch mode.
R_th(j-a)	250 K/W - thermal resistance from junction to ambient on FR4 PCB; determines derating curve above 25 °C ambient.
h_FE	40–120 at V_CE=0.35 V, I_C=10 mA - provides predictable base drive requirements for deterministic switching design.

Pinout & Package

PN2369A is housed in a plastic single-ended leaded (through-hole) TO-92 package (SOT54/SC-43A), with 3 leads, 2.54 mm lead pitch, and 14.5 mm body length - compatible with standard manual soldering and wave-solder processes.

Pin/Terminal	Circuit Role	Design Meaning
1	Collector	Main current output terminal; connects to load or supply rail in common-emitter configuration.
2	Base	Control input; requires ~1 mA drive for full saturation at 10 mA collector load.
3	Emitter	Reference node for bias and signal return; typically grounded in low-side switch topologies.

Key Features

Feature	Design Value
High-speed switching	Turn-on time ≤10 ns and storage time ≤10 ns enable clean pulse edges in timing-critical circuits.
Low saturation voltage	V_CE(sat) ≤200 mV at I_C=10 mA/I_B=1 mA reduces power dissipation and improves efficiency in saturated-mode operation.
Stable DC current gain	h_FE = 40–120 across 10–100 mA collector current ensures consistent base drive sizing without overdesign.
Low leakage	I_CBO ≤400 nA at 25 °C minimizes standby current in battery-powered or low-power logic interface applications.

Equivalent & Alternatives

The following parts are listed as comparable options for similar NPN switching transistor applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BC547B	V_CEO = 45 V, I_C = 100 mA, f_T = 300 MHz - higher voltage rating but lower current and bandwidth than PN2369A.	Better suited for general-purpose amplification; less optimal for >20 MHz switching due to slower f_T.	Select BC547B when higher breakdown voltage is required and switching speed <10 MHz is acceptable.
2N2222A	V_CEO = 40 V, I_C = 800 mA, P_tot = 500 mW - higher current capability but larger V_CE(sat) (≤1 V typical) and slower t_off (~250 ns).	Preferred for medium-power linear or switching applications where speed is secondary to current drive.	Choose 2N2222A when driving heavier loads (>200 mA) and thermal management allows higher V_CE(sat) losses.

Compared with BC547B and 2N2222A, PN2369A offers superior high-frequency performance (500 MHz f_T, ≤10 ns t_on) and tighter V_CE(sat) control, making it uniquely suited for compact, high-speed digital interface and pulse conditioning tasks where gain stability and edge fidelity are prioritized over raw voltage or current headroom.

FAQ

What is the maximum collector-emitter voltage rating for PN2369A?

The PN2369A has a maximum collector-emitter voltage (V_CEO) rating of 15 V under open-base conditions. This value is defined per IEC 60134 Absolute Maximum Ratings and must not be exceeded to prevent permanent device damage. Operation at 12 V or lower is recommended for reliability margin in sustained switching applications.

Does PN2369A support high-frequency switching above 10 MHz?

Yes, PN2369A supports high-frequency switching up to 100 MHz due to its 500 MHz transition frequency (f_T) and fast switching times (t_on ≤10 ns, t_off ≤20 ns). It is routinely used in pulse shaping, clock buffering, and digital interface circuits where edge fidelity and minimal storage time are critical - confirmed by test data in the official Philips/NXP datasheet.

What is the typical DC current gain (h_FE) of PN2369A at 10 mA collector current?

The typical DC current gain (h_FE) of PN2369A is 40–120 when measured at V_CE = 350 mV and I_C = 10 mA. This range is guaranteed across production lots and forms the basis for calculating base resistor values in saturated-switch designs using the PN2369A.

Can PN2369A be used in surface-mount designs?

No, PN2369A is only available in the through-hole TO-92 (SOT54/SC-43A) package and is not offered in any surface-mount variant. Its 3-lead leaded construction requires plated-through holes and wave or hand soldering. For SMT equivalents, consider devices like the PBSS4041T (SOT-23) with comparable f_T and V_CEO specs.

What is the thermal resistance from junction to ambient for PN2369A?

The thermal resistance from junction to ambient (R_th(j-a)) for PN2369A is 250 K/W when mounted on a standard FR4 printed-circuit board, as specified in the Philips/NXP datasheet. This value assumes no heatsink and defines the derating curve: power dissipation must be reduced by 2 mW per °C rise above 25 °C ambient.
