Product details

Overview

2STD2360T4 from STMicroelectronics is a PNP low-voltage fast-switching power transistor in TO-252 (DPAK) package, featuring V_CEO = −60 V, I_C = −3 A, V_CE(sat) = −320 mV at I_C = −3 A / I_B = −150 mA, h_FE = 160–400, and f_T = 130 MHz - used in LED driver stages and relay drive circuits requiring high gain and low saturation loss.

For engineers reviewing the 2STD2360T4 datasheet, 2STD2360T4 pinout, 2STD2360T4 application, or 2STD2360T4 equivalent, this page delivers verified electrical specs, SOT-89 vs. TO-252 package context, switching timing (t_d/t_r/t_s/t_f), thermal resistance (R_thJA = 89 °C/W on 1 cm² PCB), and direct alternatives with documented parameter divergence.

Technical Context

This device implements ST's PB-HDC (Power Bipolar High-Density Current) process to achieve simultaneous high DC current gain and ultra-low V_CE(sat), enabling efficient linear and switching operation in low-voltage (<60 V) PNP configurations. Its −60 V V_CEO and −3 A continuous collector rating support robust operation under transient overloads.

Designed for resistive-load switching, it delivers t_s = 250 ns and t_f = 50 ns at I_C = −3 A, V_CC = −10 V, with matched base drive (I_B(on) = I_B(off) = −300 mA), confirming suitability for high-duty-cycle digital control interfaces.

Key Specifications

Parameter	Value and Actual Design Meaning
V_CEO	−60 V: Maximum safe collector-emitter voltage with base open - defines rail compatibility in 48 V and lower systems
I_C	−3 A continuous: Sustained load current capability - supports medium-power relay coils and LED strings
V_CE(sat)	−320 mV at −3 A/−150 mA: Low conduction loss - reduces heat generation in high-duty-cycle switching
h_FE	160–400 at −100 mA to −1 A: High and stable current amplification - enables simple base-drive design with low gate-drive current
f_T	130 MHz: Transition frequency - confirms usable bandwidth for PWM up to ~10 MHz with margin
R_thJA	89 °C/W on 1 cm² PCB: Thermal resistance - determines heatsink-free operation up to ~0.8 W dissipation at ambient 70 °C
t_s/t_f	250 ns / 50 ns: Storage/fall time - enables clean turn-off in <1 µs switching cycles without tail current

Pinout & Package

2STD2360T4 is housed in TO-252 (DPAK) package: surface-mount, single-drain tab, three-terminal outline with exposed thermal pad. Pin 1 = Emitter, Pin 2 = Base, Pin 3 = Collector (tab).

Pin/Terminal	Circuit Role	Design Meaning
Emitter (Pin 1)	Current source terminal for PNP device	Connected to positive rail in high-side switch configuration - sets reference for base bias and current sensing
Base (Pin 2)	Control input for minority-carrier injection	Receives negative current to turn on; requires −150 mA for full saturation at −3 A load
Collector (Pin 3 / Tab)	Output current sink terminal	Electrically and thermally connected to PCB copper pour - primary path for heat removal and load return

Key Features

Feature	Design Value
Very low V_CE(sat)	−320 mV at −3 A ensures <1 W conduction loss - eliminates need for active cooling in compact LED drivers
High h_FE range	160–400 across operating current enables consistent gain with minimal base drive variation - simplifies discrete logic-level interface
Fast storage/fall time	t_s = 250 ns, t_f = 50 ns - prevents shoot-through in complementary PNP/NPN H-bridges and enables >500 kHz PWM
PB-HDC process technology	ST's proprietary bipolar process delivers simultaneous high gain and low saturation - replaces older PNP devices requiring external gain-boosting networks

Applications

LED Driver Stage

Relay Drive Circuit

Use Scenario: Driving high-brightness LED strings in emergency lighting systems with 24–48 V supply rails.

IC Role / Device Role / Timing Role: PNP high-side switch controlling current flow through LEDs during battery-backup operation.

Use Value: −320 mV V_CE(sat) minimizes voltage drop and thermal rise, preserving battery runtime and enabling compact PCB layout.

Use Scenario: Activating 24 V DC industrial relays in PLC output modules with microcontroller GPIO control.

IC Role / Device Role / Timing Role: Medium-current PNP switch interfacing between 3.3 V logic and relay coil, handling inductive kickback via snubber.

Use Value: 160–400 h_FE allows direct drive from MCU pins with series resistor only - no level-shifter or Darlington stage required.

Voltage Regulation Feedback

Emergency Lighting Control

Use Scenario: Precision current sourcing in adjustable linear voltage regulators using PNP pass element.

IC Role / Device Role / Timing Role: Pass transistor in series-regulator topology, modulated by error amplifier to maintain output stability.

Use Value: Low V_BE(on) (−650 mV typ.) and tight V_CE(sat) tolerance ensure predictable dropout and load regulation across temperature.

Use Scenario: Automatic switchover from mains to battery backup in commercial emergency lighting fixtures.

IC Role / Device Role / Timing Role: Fast-acting PNP switch enabling seamless transition between AC-derived and battery-derived power paths.

Use Value: 50 ns fall time ensures no interruption during switchover - critical for maintaining illumination during grid failure.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
STN2360T4	Same die, SOT-89 package - R_thJA = 89 °C/W but smaller footprint and lower I_CM (−5 A vs. −5 A same); identical V_CE(sat) and h_FE	Suitable for space-constrained boards where thermal mass is limited; not ideal for high-reliability TO-252 mounting	Select when board area is critical and thermal management uses localized copper; avoid if mechanical robustness or long-term power cycling is required
MJD2360T4	ON Semiconductor part: V_CEO = −60 V, I_C = −3 A, but V_CE(sat) = −500 mV (max) at −3 A - 56% higher conduction loss	Acceptable for intermittent relay drive, but unsuitable for continuous LED current regulation due to thermal derating	Choose only if ST parts are unavailable; expect 20–25 °C higher junction temp at same load - requires larger heatsinking

Compared with STN2360T4, 2STD2360T4 offers superior mechanical reliability and thermal interface in TO-252; versus MJD2360T4, it delivers significantly lower V_CE(sat) and tighter h_FE distribution - directly reducing system-level power loss and base-drive complexity.

FAQ

What is the maximum continuous collector current for 2STD2360T4?

The maximum continuous collector current (I_C) is −3 A at T_amb = 25 °C with adequate PCB copper area. Derating applies above 25 °C per the R_thJA = 89 °C/W thermal resistance - at 70 °C ambient, max I_C drops to approximately −2.2 A to maintain T_J ≤ 150 °C.

Does 2STD2360T4 require a heatsink in typical relay drive applications?

No heatsink is required for typical relay drive use (duty cycle <10%, I_C ≤ −1 A) on standard FR-4 with ≥1 cm² copper pour. At full −3 A continuous, junction temperature reaches ~125 °C with 1 cm² copper - acceptable for most industrial environments but may warrant thermal relief for extended 100% duty cycles.

How does the PB-HDC process improve performance over conventional bipolar processes?

PB-HDC enhances carrier density and emitter efficiency, yielding both high h_FE (≥160 at −1 A) and low V_CE(sat) (−320 mV) simultaneously - unlike legacy processes that trade one for the other. This eliminates need for Darlington pairing or external gain compensation in medium-power PNP switches.

Can 2STD2360T4 be used in complementary symmetry amplifier stages?

Yes - its matched f_T (130 MHz), tight h_FE spread (160–400), and symmetric switching times (t_r/t_f ≈ 15/50 ns) support use with NPN counterparts like 2SD2360T4 in Class-B or AB output stages, provided V_CEO and I_C ratings are respected in the target bias point.
