Product details

Overview

2STL1360 from STMicroelectronics is a low-voltage, fast-switching NPN power transistor in TO-92L package, featuring 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 f_T = 130 MHz. It delivers high current gain with very low saturation voltage for efficient switching in LED drivers and relay control circuits.

For engineers reviewing the 2STL1360 datasheet, 2STL1360 pinout, 2STL1360 application, or 2STL1360 equivalent, this device is selected for low-loss, medium-current (<3 A) linear and switching roles where thermal resistance (R_thJA = 104 °C/W) and fast turn-off (t_f = 54–65 ns) are critical in emergency lighting and voltage regulation designs.

Technical Context

This NPN bipolar junction transistor uses ST's PB-HCD (Power Bipolar High Current Density) process to achieve simultaneous high h_FE and low V_CE(sat). Its DC current gain remains stable across I_C = 0.1 A to 1 A at V_CE = 2 V, supporting robust base drive design in saturated-switching configurations.

Switching performance is characterized under resistive-load conditions (V_CC = 10 V, I_C = 3 A, I_B(on/off) = ±300 mA), with t_s = 620–720 ns dominating total delay-indicating storage-time-limited turn-off behavior typical of high-gain power BJTs.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - supports operation in 24–48 V DC systems without breakdown risk
I_C	3 A continuous - suitable for driving relays, LED strings, or linear regulators up to ~15 W dissipation
V_CE(sat)	130 mV typ. @ 2 A/100 mA - reduces conduction loss by >50% vs. standard general-purpose transistors
h_FE	160–400 @ I_C = 0.1–1 A - enables low-base-drive-current operation, easing MCU GPIO or logic-level drive
f_T	130 MHz - confirms usable bandwidth beyond audio and low-speed digital switching frequencies
R_thJA	104 °C/W (TO-92L) - limits max ambient temperature to ~75 °C at full 1.2 W dissipation
t_f	54–65 ns - ensures clean turn-off in PWM dimming and relay coil de-energization

Pinout & Package

2STL1360 is housed in a TO-92L plastic package (lead length ≥13.3 mm, body width 4.7–5.1 mm), optimized for improved thermal dissipation over standard TO-92.

Pin/Terminal	Circuit Role	Design Meaning
E (Emitter)	Current sink terminal	Connected to ground or low-side return path; carries full load current
B (Base)	Control input	Receives forward bias current to saturate transistor; requires current-limiting resistor
C (Collector)	Current source terminal	Connected to load supply rail; handles switched load current up to 3 A

Key Features

Feature	Design Value
Very low V_CE(sat)	130 mV typ. at 2 A - cuts conduction loss to <260 mW, enabling compact thermal design
High h_FE range	160–400 - allows use of small base drive signals (e.g., 3.3 V MCU outputs with R_B ≈ 22 Ω)
Fast switching speed	t_f = 54–65 ns - supports PWM frequencies up to ~1 MHz in non-critical timing applications
PB-HCD process technology	Enables simultaneous high gain and low saturation - eliminates trade-off between drive efficiency and on-state loss

Applications

Emergency Lighting Control

LED Constant-Current Driver

Use Scenario: Battery-backed DC lighting system requiring reliable on/off switching during mains failure.

IC Role / Device Role / Timing Role: NPN power switch controlling current flow to LED array or incandescent lamp.

Use Value: Low V_CE(sat) minimizes battery drain during extended operation; high h_FE ensures full saturation from microcontroller GPIO.

IC Role / Device Role / Timing Role: Pass transistor regulating LED current via feedback-controlled base bias.

Use Value: Tight V_CE(sat) tolerance (130–300 mV) ensures stable current setting; low thermal resistance sustains output at ambient up to 75 °C.

Voltage Regulation

Relay Drive Interface

Use Scenario: Low-dropout series pass element in discrete 5–12 V linear regulators for noise-sensitive analog circuits.

IC Role / Device Role / Timing Role: Series-pass transistor adjusting output voltage via error-amplifier controlled base current.

Use Value: High h_FE reduces base drive burden on error amplifier; low V_CE(sat) extends dropout margin to <200 mV.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
MJD122G	V_CE(sat) = 1.5 V @ 3 A - 10× higher than 2STL1360; h_FE = 20–100 - lower gain	Higher conduction loss limits use to intermittent-duty relays; unsuitable for linear regulation or battery-powered LED drivers	Select when cost priority outweighs efficiency, and thermal budget permits higher dissipation
ZTX653	V_CE(sat) = 250 mV @ 2 A - ~2× higher; h_FE = 200–600 - wider spread; TO-92 package only	Acceptable for LED drivers but less efficient; higher R_thJA (~125 °C/W) restricts power handling in sealed enclosures	Choose if legacy TO-92 footprint compatibility is required and 130 mV V_CE(sat) is not mandatory

Compared with MJD122G and ZTX653, the 2STL1360 uniquely combines sub-150 mV saturation voltage with h_FE >160 and TO-92L thermal enhancement-making it optimal for efficiency-critical, medium-current linear and switching roles where thermal headroom is constrained.

FAQ

What is the maximum continuous collector current for 2STL1360?

The absolute maximum continuous collector current (I_C) is 3 A at T_amb = 25 °C. Derating is required above 25 °C per the R_thJA = 104 °C/W specification; at 75 °C ambient, max I_C drops to approximately 2.3 A to maintain T_J ≤ 150 °C.

Can 2STL1360 be used in PWM-driven LED dimming circuits?

Yes-it supports PWM dimming up to ~1 MHz due to its 130 MHz f_T and 54–65 ns fall time. However, its storage time (t_s = 620–720 ns) dominates switching delay, so minimum off-time should exceed 1 µs to ensure full turn-off before next cycle.

Is 2STL1360 pin-compatible with 2STX1360?

Yes-both share identical pinout (E-B-C) and electrical specifications, differing only in package (TO-92L vs. TO-92) and thermal resistance (104 vs. 125 °C/W). PCB footprints must match respective package outlines; TO-92L offers better thermal performance for sustained 2–3 A operation.

Does 2STL1360 require a base resistor, and how is its value calculated?

Yes-a series base resistor is mandatory to limit I_B. For saturation at I_C = 2 A, use h_FE(min) = 160 → I_B ≥ 12.5 mA. With V_BE(on) ≈ 0.65 V and 3.3 V drive, R_B = (3.3 V − 0.65 V)/12.5 mA ≈ 212 Ω; a standard 220 Ω resistor ensures reliable saturation.
