Product details

Overview

BTS132 from Infineon Technologies is an N-channel logic-level enhancement-mode Power MOSFET with integrated temperature-sensing thyristor, rated for 60 V V_DS, 24 A continuous drain current at T_C = 25 °C, and 0.065 Ω R_DS(on) at V_GS = 4.5 V - used in motor control, power supply protection, and thermal shutdown circuits where self-protecting switching is required.

For engineers reviewing the BTS132 datasheet, BTS132 pinout, BTS132 application, or BTS132 equivalent, key selection criteria include its integrated temperature-triggered thyristor behavior (T_TS(on) = 150 °C), short-circuit withstand capability (I_SC ≤ 80 A, P_SCmax = 1200 W), and TO-220AB package with drain-connected tab for direct heatsinking.

Technical Context

The BTS132 integrates a high-current N-channel MOSFET and a monolithically embedded temperature sensor with thyristor latching behavior: when junction temperature reaches ~150 °C, the sensor triggers internal gate discharge, forcing the MOSFET into safe shutdown. Its R_DS(on) of 0.055 Ω (typ.) at V_GS = 4.5 V enables efficient low-voltage drive, while the drain-to-tab short ensures low thermal resistance (R_thJC ≤ 1.67 K/W).

It supports short-circuit protection with response time t_SC(off) = 25 ms at T_j = 25 °C and operates across –55 °C to +150 °C junction range. The built-in body diode has V_SD = 1.3–1.8 V at I_F = 24 A and t_rr = 150 ns, enabling fast freewheeling in inductive loads.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - maximum blocking voltage before avalanche; suitable for 48 V DC systems and industrial 24–48 V bus applications.
I_D (continuous)	24 A at T_C = 25 °C - defines steady-state load current capability with adequate heatsinking.
R_DS(on)	0.065 Ω max at V_GS = 4.5 V - determines conduction loss (P_cond ≈ I² × R) in low-side switching topologies.
T_TS(on)	150 °C - precise thermal trip point for autonomous overtemperature shutdown without external circuitry.
I_SC	≤ 80 A - peak short-circuit current the device sustains for defined duration before triggering protection.
R_thJC	≤ 1.67 K/W - enables direct mounting to heatsink via electrically active tab for minimal thermal path.
t_rr	150 ns - reverse recovery time of integrated body diode; critical for minimizing switching losses in inductive flyback.

Pinout & Package

Package: TO-220AB with drain electrically connected to metal tab - requires insulated mounting hardware if tab is not at system ground potential.

Pin/Terminal	Circuit Role	Design Meaning
Pin 1 (Gate)	Control input	Accepts logic-level gate drive (V_GS(th) = 1.5–2.5 V); low input capacitance (C_iss = 1050 pF typ.) eases driver selection.
Pin 2 (Drain)	High-side or low-side power switch node	Internally shorted to metal tab; must be isolated from chassis unless referenced to common ground.
Pin 3 (Source)	Reference terminal for gate drive and current return	Serves as current sense reference and gate drive return; connects to PCB ground plane for stable switching.

Key Features

Feature	Design Value
Integrated temperature-sensing thyristor	Autonomous shutdown at T_j = 150 °C with <2.5 µs turn-off time - eliminates need for external thermal IC or microcontroller polling.
Logic-level gate drive compatibility	V_GS(th) = 1.5–2.5 V and R_DS(on) specified at V_GS = 4.5 V - directly drivable by 3.3 V or 5 V microcontrollers without level-shifting.
Short-circuit robustness	Withstands 1200 W short-circuit dissipation for defined duration (t_SC(off) = 25 ms) - enables reliable operation in motor stall or wiring fault conditions.
Drain-to-tab connection	Reduces thermal resistance to heatsink (R_thJC ≤ 1.67 K/W) - improves power handling and simplifies thermal design in space-constrained enclosures.

Applications

Motor Overtemperature Protection

DC Power Rail Protection

Use Scenario: Integrated into BLDC motor driver PCBs to monitor winding temperature and disable gate drive upon thermal runaway.

IC Role / Device Role / Timing Role: Self-protecting power switch with embedded thermal trip - replaces discrete MOSFET + external thermistor + comparator.

Use Value: Eliminates BOM cost and layout area for thermal sensing circuitry while guaranteeing shutdown within 2.5 µs after reaching 150 °C.

Use Scenario: Used as main power switch in 48 V telecom or industrial power distribution units with overcurrent and overtemperature fault coverage.

IC Role / Device Role / Timing Role: High-reliability load switch with dual-fault detection (short-circuit + thermal) - acts as intelligent fuse replacement.

Use Value: Delivers 1200 W short-circuit energy handling and automatic latch-off, reducing risk of fire or cascade failure during sustained overload.

Thermal Shutdown for LED Drivers

Industrial Solenoid Control

Use Scenario: Controls high-power LED arrays in outdoor lighting fixtures exposed to ambient temperatures up to +85 °C.

IC Role / Device Role / Timing Role: Current-regulated switch with thermal foldback - shuts down before LED phosphor degradation or lens yellowing occurs.

Use Value: Prevents irreversible optical degradation by enforcing hard cutoff at 150 °C junction, independent of ambient sensor placement errors.

Use Scenario: Drives 24 V solenoid valves in factory automation PLC output modules subject to frequent inductive kickback and coil overheating.

IC Role / Device Role / Timing Role: Inductive load switch with integrated freewheeling diode and thermal latch - handles back-EMF and coil thermal drift simultaneously.

Use Value: Avoids external snubber components and thermal monitoring ICs; maintains functional safety without software intervention.

Equivalent & Alternatives

The following parts are listed as comparable options for similar thermal-protected power switch applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
Infineon BTS142	V_DS = 60 V, I_D = 30 A, R_DS(on) = 0.045 Ω, same TEMPFET® architecture and T_TS(on) = 150 °C	Higher current rating supports larger motors or parallel configurations; identical thermal response and protection timing	Select when higher continuous current headroom or lower conduction loss is needed without changing thermal trip behavior.
STMicroelectronics STD13NF06L	N-channel MOSFET only - no integrated temperature sensor or thyristor; V_DS = 60 V, I_D = 13 A, R_DS(on) = 0.09 Ω	Requires external thermal management circuitry (e.g., NTC + comparator) to achieve comparable overtemperature protection	Choose only if full custom thermal control is preferred and board space allows additional components.

Compared with BTS132, BTS142 offers higher current capacity and lower R_DS(on) while preserving identical thermal trip behavior and protection timing; STD13NF06L lacks integrated thermal sensing entirely, requiring external circuitry to replicate basic overtemperature shutdown functionality.

FAQ

What is the function of the temperature sensor in BTS132?

The integrated temperature sensor is a thyristor-based structure that triggers at approximately 150 °C junction temperature, causing rapid gate discharge and forcing the MOSFET into a latched-off state. It operates autonomously without external bias or control signals, providing hardware-level thermal protection with <2.5 µs turn-off time.

Can BTS132 be used in high-side switching configurations?

Yes, but with caution: Pin 2 (Drain) is electrically connected to the metal tab, so high-side use requires full isolation of the tab from chassis ground. Gate drive must be referenced to source potential, and level-shifting may be needed depending on controller output voltage and load voltage.

Does BTS132 require external gate resistors for stability?

A gate resistor (typically 10–47 Ω) is recommended to dampen ringing caused by gate-drain capacitance (C_rss = 200–300 pF) and PCB trace inductance. Without it, fast edge rates (t_r = 150–200 ns) may cause oscillation or false triggering, especially under high di/dt conditions.

How does short-circuit protection work in BTS132?

Under short-circuit, the device limits current based on V_GS and channel characteristics, then monitors junction temperature rise. When localized heating reaches ~150 °C, the integrated thyristor activates, discharging the gate and turning off the MOSFET within 25 ms - independent of external control, ensuring fail-safe shutdown even during MCU lockup.
