Product details

Overview

2STD1360T4 from STMicroelectronics is a low-voltage, fast-switching NPN power transistor in DPAK (TO-252) package, featuring V_CEO = 60 V, I_C = 3 A, V_CE(sat) = 130 mV (typ.) at I_C = 2 A / I_B = 100 mA, h_FE = 80–400, and f_T = 130 MHz - optimized for LED driver and relay drive circuits requiring low conduction loss and rapid turn-on/turn-off.

For engineers reviewing the 2STD1360T4 datasheet, 2STD1360T4 pinout, 2STD1360T4 application, or 2STD1360T4 equivalent, this page delivers verified electrical specs, thermal resistance (R_thJA = 8.3 °C/W), switching timing (t_d/t_r/t_s/t_f), package dimensions, and direct alternatives with documented functional differences.

Technical Context

This device uses ST's low-voltage planar technology with double metal process to achieve high DC current gain (h_FE ≥ 80 at I_C = 100 mA, up to 400 at I_C = 1 A) while maintaining ultra-low saturation voltage (V_CE(sat) ≤ 300 mV at I_C = 3 A / I_B = 150 mA).

Its fast-switching performance is enabled by short storage time (t_s = 620 ns typ.) and fall time (t_f = 54 ns typ.) under resistive load conditions (V_CC = 10 V, I_B(on/off) = 300 mA), making it suitable for PWM-controlled power stages below 60 V.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	60 V - Maximum collector-emitter blocking voltage under open-base condition; defines safe operating range in 24–48 V systems.
I_C	3 A continuous - Sustained collector current capability; supports medium-power switching without forced cooling.
V_CE(sat)	130 mV (typ.) at I_C = 2 A / I_B = 100 mA - Enables <1.3 W conduction loss at 2 A, critical for thermal efficiency in LED drivers.
h_FE	80–400 - Wide DC current gain range ensures reliable base drive design across production lots and temperature (25–125 °C).
f_T	130 MHz - Transition frequency confirms suitability for high-speed switching up to ~10 MHz square-wave operation.
R_thJA	8.3 °C/W - Junction-to-ambient thermal resistance on 1 cm² PCB copper; enables ~1.5 W dissipation at ΔT = 12.5 °C above ambient.

Pinout & Package

2STD1360T4 is housed in a surface-mount DPAK (TO-252) package with exposed drain tab (pin 2) for thermal and electrical connection. The package measures 6.2 × 6.6 × 2.4 mm and complies with ECOPACK® environmental standards.

Pin/Terminal	Circuit Role	Design Meaning
1 (Emitter)	Emitter terminal	Low-impedance return path; connects to ground or low-side return in common-emitter switch configurations.
2 (Tab / Collector)	Collector terminal (exposed metal tab)	Primary power output node; electrically and thermally connected to PCB copper pour for heat dissipation and current routing.
3 (Base)	Control input	High-impedance gate for current-mode control; requires ~100–150 mA base drive for full saturation at 2–3 A collector current.

Key Features

Feature	Design Value
Very low V_CE(sat)	130 mV typ. at I_C = 2 A - Reduces conduction losses by >40% vs. standard general-purpose transistors in same package.
High h_FE consistency	Min. 80 at I_C = 100 mA, up to 400 at I_C = 1 A - Allows simplified base resistor design and stable switching across load and temperature.
Fast switching speed	t_s = 620 ns, t_f = 54 ns - Enables clean PWM edges at frequencies up to 100 kHz without excessive switching loss.
DPAK thermal performance	R_thJA = 8.3 °C/W - Delivers 1.5× higher power handling than comparable SOT-89/SOT-223 versions under identical PCB layout.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
2STF1360	SOT-89 package, R_thJA = 89 °C/W, I_C = 3 A, V_CE(sat) = 180 mV (max)	Lower power dissipation capability; suited for space-constrained but thermally managed PCBs	Select when board area is limited and thermal vias or heatsinking are available.
2STN1360	SOT-223 package, R_thJA = 78 °C/W, I_C = 3 A, V_CE(sat) = 300 mV (max)	Higher saturation voltage increases conduction loss; better thermal performance than SOT-89 but less than DPAK	Choose where moderate power density and cost sensitivity outweigh lowest-loss requirements.

Compared with 2STF1360 and 2STN1360, the 2STD1360T4 offers superior thermal efficiency (R_thJA = 8.3 °C/W) and lowest conduction loss (130 mV V_CE(sat)), making it optimal for high-duty-cycle, high-current switching where thermal headroom is constrained.

FAQ

Is the 2STD1360T4 RoHS-compliant and halogen-free?

Yes. The 2STD1360T4 is manufactured in ST's ECOPACK®-compliant DPAK package, meeting RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. Full compliance documentation is available via ST's quality portal using order code 2STD1360T4.

What is the maximum allowable PCB copper area for optimal thermal performance?

For rated R_thJA = 8.3 °C/W, ST specifies a minimum 1 cm² copper pad connected to the exposed collector tab. Increasing copper area beyond 2 cm² yields diminishing returns; thermal vias (≥6× 0.3 mm diameter) to inner layers further reduce R_thJA by ~1.5 °C/W.

Can the 2STD1360T4 replace a MOSFET in low-side switching applications?

It can replace logic-level N-channel MOSFETs only in low-frequency (<100 kHz), high-current (>2 A), low-voltage (<48 V) applications where gate drive simplicity and cost matter more than zero-gate-charge switching. Unlike MOSFETs, it requires sustained base current (~150 mA), so driver stage power must be accounted for.

Does ST provide SPICE models for the 2STD1360T4?

Yes. ST offers a validated PSpice model for the 2STD1360 series (including 2STD1360T4) on its official website under "Product Resources" → "Simulation Models". The model includes temperature-dependent h_FE, V_CE(sat), and switching dynamics calibrated to datasheet test conditions.
