Product details

Overview

2STX1360 from STMicroelectronics is a low-voltage, fast-switching NPN power transistor manufactured using PB-HCD (Power Bipolar High Current Density) technology. It delivers V_CE(sat) = 130 mV (typ.) at I_C = 2 A / I_B = 100 mA, h_FE = 160–400 (I_C = 0.1–1 A), and t_f = 54 ns (max), enabling efficient relay drive and LED current control in compact DC-DC and emergency lighting circuits.

For engineers reviewing the 2STX1360 datasheet, 2STX1360 pinout, 2STX1360 application, or 2STX1360 equivalent, key selection criteria include verified V_CE(sat) performance under 2 A load, guaranteed h_FE ≥ 80 at 100 mA, TO-92 package thermal resistance (R_thJA = 125 °C/W), and documented resistive-load switching times (t_d/t_r/t_s/t_f) per Figure 6.

Technical Context

This NPN bipolar junction transistor operates with V_CEO = 60 V and I_C = 3 A continuous, optimized for linear and saturated switching in low-to-mid power DC applications. Its PB-HCD process enables simultaneous high current gain and low saturation voltage-unlike conventional planar BJTs where these traits trade off.

The device exhibits f_T = 130 MHz at I_C = 0.1 A / V_CE = 10 V, supporting fast edge transitions, while its R_thJA = 125 °C/W (TO-92) defines thermal derating above 25 °C ambient. Switching behavior is characterized under non-inductive resistive load (V_CC = 10 V, I_C = 3 A, I_B(on/off) = ±300 mA).

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum safe collector-emitter voltage with base open; sets upper limit for DC supply rails in relay/LED driver stages.
I_C (cont.)	3 A - Continuous collector current rating; supports direct driving of 2.5 A LED strings or 24 V/1 A relays without heatsinking below 50 °C ambient.
V_CE(sat)	130 mV (typ.) @ I_C=2 A/I_B=100 mA - Low conduction loss reduces power dissipation to ≤260 mW, minimizing thermal stress in TO-92 packages.
h_FE	160–400 @ I_C=0.1–1 A - High DC current gain allows low-base-drive-current operation, easing microcontroller GPIO interface design.
t_f	54 ns (max) - Fast fall time enables PWM dimming up to ~1 MHz in LED drivers without significant switching loss penalties.
f_T	130 MHz - Transition frequency confirms usable small-signal amplification bandwidth, relevant for analog feedback or oscillator designs.
R_thJA	125 °C/W - Junction-to-ambient thermal resistance defines safe operating area: max P_D drops to ~0.64 W at 75 °C ambient.

Pinout & Package

2STX1360 is housed in a standard TO-92 plastic package (JEDEC TO-226AA), with lead finish compliant with ECOPACK® environmental specifications. Pin assignment follows emitter-base-collector (E-B-C) configuration when viewed with flat side facing user and leads downward.

Pin/Terminal	Circuit Role	Design Meaning
Emitter (E)	Current sink terminal	Connected to ground or low-side return path; must handle full load current (3 A) and support low-impedance PCB routing.
Base (B)	Control input	Receives TTL/CMOS-compatible drive (V_BE(on) = 630–730 mV); requires series resistor to limit I_B ≤ 0.2 A peak.
Collector (C)	Current source terminal	Connected to positive rail or load anode; withstands 60 V transient spikes and dissipates majority of switching/conduction loss.

Key Features

Feature	Design Value
Very low V_CE(sat)	130 mV typ. at 2 A ensures <260 mW conduction loss-critical for thermally constrained TO-92 layouts in battery-powered lighting.
High h_FE range	80–400 across 0.1–1 A collector current enables stable biasing with minimal base drive overhead in microcontroller-driven systems.
Fast switching (t_s + t_f)	674 ns max total storage + fall time supports clean 500 kHz PWM operation with <5% duty-cycle distortion in LED dimming.
PB-HCD process technology	Enables concurrent optimization of gain and saturation voltage-unachievable in legacy BJT processes-yielding higher efficiency in linear regulation.

Applications

Emergency Lighting Control

LED Constant-Current Driver

Use Scenario: Battery-backed DC-DC boost stage driving white LED strings during AC mains failure.

IC Role / Device Role / Timing Role: NPN switch controlling LED cathode current path; operates in saturation during on-time, cut-off during off-time.

Use Value: V_CE(sat) ≤ 180 mV at 2 A minimizes dropout loss, extending runtime by >12% vs. standard transistors with 400 mV saturation.

Use Scenario: Linear current regulator for automotive interior LED map lights (12 V supply, 350 mA nominal).

IC Role / Device Role / Timing Role: Pass element in adjustable constant-current sink topology; biased via op-amp feedback loop.

Use Value: h_FE ≥ 160 at 350 mA ensures stable loop gain and <±2% current regulation over temperature (−40 to +85 °C).

Voltage Regulation

Relay Drive Interface

Use Scenario: Low-dropout series pass transistor in 5 V/2 A linear regulator for MCU power domain.

IC Role / Device Role / Timing Role: Power transistor in emitter-follower configuration; dissipates excess voltage as heat.

Use Value: R_thJA = 125 °C/W and V_CE(sat) = 130 mV allow full 2 A output at ≤65 °C case temperature with no heatsink.

Use Scenario: Driving 24 V/500 mA electromagnetic relay coil from 3.3 V microcontroller GPIO.

IC Role / Device Role / Timing Role: Low-side switch sinking relay coil current; activated/deactivated via PWM or digital signal.

Use Value: t_f = 54 ns prevents contact arcing during turn-off, extending relay mechanical life beyond 100,000 cycles.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD112	V_CEO = 100 V, I_C = 2 A, V_CE(sat) = 1.5 V @ 1 A - higher saturation voltage, lower current rating.	Less suitable for 2 A LED loads due to 1.5 V drop causing >1.5 W dissipation in TO-220; better for higher-voltage, lower-current relay control.	Select when V_CEO > 80 V is required and thermal budget permits higher V_CE(sat).
BCP56-10	SOT-223 package, I_C = 1 A, h_FE = 100–300 - smaller footprint but lower current and power handling.	Appropriate for space-constrained 500 mA LED drivers; unsuitable for 3 A relay coils or emergency lighting loads.	Choose for PCB area savings where load current ≤ 1 A and thermal management uses copper pour instead of air convection.

Compared with MJD112 and BCP56-10, 2STX1360 uniquely balances 3 A current capability, 130 mV V_CE(sat), and TO-92 usability-making it optimal for cost-sensitive, thermally moderate 2–3 A DC switching where SMT alternatives lack sufficient SOA.

FAQ

What is the maximum safe operating temperature for 2STX1360?

The absolute maximum junction temperature (T_J) is 150 °C, and storage temperature range is −65 to +150 °C. With R_thJA = 125 °C/W, sustained 3 A operation requires ambient ≤ 40 °C or PCB copper thermal relief to avoid exceeding T_J limit.

Can 2STX1360 replace a MOSFET in low-side switching applications?

Yes-but only where gate drive simplicity and cost outweigh efficiency needs. Unlike MOSFETs, it requires continuous base current (≥100 mA for 2 A I_C) and has higher conduction loss. Use only when V_GS drive is unavailable or thermal margin exists for 130–300 mV V_CE(sat).

Is 2STX1360 RoHS-compliant and halogen-free?

Yes. Per ST's ECOPACK® documentation, 2STX1360 meets RoHS Directive 2011/65/EU and is halogen-free per IEC 61249-2-21. The TO-92 package uses lead-free matte tin plating and compliant molding compound.

Does 2STX1360 require a base resistor, and what value is recommended?

Yes-a series base resistor is mandatory to limit I_B within 0.2 A absolute max. For 3.3 V GPIO driving 2 A collector current with h_FE = 160, R_B = (3.3 V − 0.7 V) / (2 A / 160) ≈ 208 Ω; use 220 Ω 1/4 W standard value for safety margin.
