Product details

Overview

BTS113AE3045ANTMA1 from Infineon Technologies is an N-channel logic-level enhancement-mode TEMPFET® power MOSFET with integrated temperature-sensing thyristor, rated for 60 V V_DS, 11.5 A continuous drain current at T_C = 25 °C, and 0.17 Ω R_DS(on) at V_GS = 4.5 V - used in automotive load switching with self-protecting thermal shutdown.

For engineers reviewing the BTS113AE3045ANTMA1 datasheet, BTS113AE3045ANTMA1 pinout, BTS113AE3045ANTMA1 application, or BTS113AE3045ANTMA1 equivalent, key selection criteria include its integrated overtemperature latch (T_TS(on) = 150 °C), short-circuit robustness (I_SC = 27 A), and TO-220AB package with drain-connected tab for direct heatsinking.

Technical Context

This device combines a high-current N-channel MOSFET with a monolithically integrated silicon temperature sensor exhibiting thyristor-like latching behavior above 150 °C - enabling autonomous, non-volatile thermal shutdown without external control circuitry. Its gate threshold voltage (1.6–2.5 V) and R_DS(on) stability across temperature support direct microcontroller drive and predictable conduction loss in 12 V automotive systems.

The drain is electrically connected to the metal tab, establishing a low-impedance thermal path and requiring electrical isolation when mounted to heatsinks. Short-circuit protection operates within 20 ms response time at T_j = 25 °C, with dissipation capability up to 400 W during fault events.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 12 V automotive battery systems with margin against load-dump transients
I_D (continuous, T_C = 25 °C)	11.5 A - enables high-side or low-side switching of solenoids, fans, and lighting loads
R_DS(on) (V_GS = 4.5 V)	0.17 Ω max - limits conduction loss to ≤2.2 W at 11.5 A, reducing heatsink requirements
T_TS(on)	150 °C - precise, repeatable thermal trip point for automatic overtemperature lockout
I_SC	27 A - sustains short-circuit current without destruction for ≥20 ms under defined conditions
t_off (sensor)	0.5–2.5 µs - fast thyristor turn-off ensures rapid system disable after thermal event
V_SD (diode)	1.3–1.6 V - body diode forward voltage enables freewheeling in inductive load applications

Pinout & Package

Package: TO-220AB with electrically active drain-connected metal tab (requires insulated mounting hardware).

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Logic-level compatible; drives directly from 3.3 V/5 V MCUs without level-shifting
2 (Drain)	Power output / High-side switch node	Internally bonded to metal tab - must be electrically isolated from heatsink
3 (Source)	Power return / Reference node	Common return path for load current and gate drive reference; defines ground-referenced operation

Key Features

Feature	Design Value
Integrated temperature-sensing thyristor	Latches off at 150 °C with no external bias or control - eliminates need for discrete thermal cutoff circuits
Drain-to-tab connection	Enables lowest possible thermal resistance (R_thJC ≤ 3.1 K/W) but mandates dielectric isolation in mechanical assembly
Logic-level gate drive	V_GS(th) = 1.6–2.5 V allows direct interface with automotive microcontrollers and CAN/LIN transceivers
Short-circuit ruggedness	Withstands 27 A fault current for ≥20 ms at T_j = 25 °C - supports fail-safe operation in motor and solenoid drivers
Body diode with low Q_rr	Q_rr = 0.10 µC - minimizes switching losses and EMI in inductive load commutation

Applications

Automotive Door Lock Actuator

Engine Cooling Fan Control

Use Scenario: Bidirectional locking/unlocking of door latch solenoids in 12 V vehicle architectures.

IC Role / Device Role / Timing Role: High-side load switch providing current-limited, thermally protected actuation with autonomous shutdown on coil stall.

Use Value: Eliminates external thermal fuse and current sense amplifier; reduces BOM count by two components while improving reliability.

Use Scenario: PWM-controlled cooling fan driver subject to stalled-rotor faults and ambient temperatures up to 105 °C.

IC Role / Device Role / Timing Role: Low-side switching element with integrated overtemperature latch that disables fan permanently until system reset.

Use Value: Prevents thermal runaway during blade obstruction - avoids connector melting and harness damage without software intervention.

Headlight Beam Selector

Seat Heater Power Stage

Use Scenario: Switching between high/low beam filaments in halogen or LED headlamp modules.

IC Role / Device Role / Timing Role: High-side switch managing 8–10 A filament loads with fast thermal response to bulb open-circuit or overvoltage events.

Use Value: Self-shutdown at 150 °C prevents PCB delamination and lens yellowing caused by sustained overtemperature operation.

Use Scenario: 12 V resistive heating element control in automotive seats, operating continuously at elevated cabin temperatures.

IC Role / Device Role / Timing Role: Low-side power stage with built-in thermal cutoff that deactivates heater before skin-burn thresholds are exceeded.

Use Value: Meets ISO 14572 occupant safety requirements without adding discrete thermal sensors or watchdog timers.

Equivalent & Alternatives

The following parts are listed as comparable options for similar temperature-protected MOSFET applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS112AE3045ANTMA1	Lower V_DS (40 V), same R_DS(on) and T_TS(on); reduced short-circuit energy rating (P_SCmax = 250 W)	Suitable only for 5–6 V auxiliary systems or low-voltage EV submodules - not for 12 V main battery loads	Select when lower voltage rating and cost reduction outweigh short-circuit robustness needs
BTS114AE3045ANTMA1	Higher V_DS (80 V), higher R_DS(on) (0.22 Ω), identical thermal latch and package	Better suited for 24 V commercial vehicles or 48 V mild-hybrid systems where higher blocking voltage is critical	Choose for future-proofing in multi-voltage platforms or where load-dump immunity >60 V is required

Compared with BTS112A and BTS114A, the BTS113A uniquely balances 60 V blocking, 11.5 A current handling, and 400 W short-circuit dissipation - making it optimal for mainstream 12 V automotive power distribution where thermal autonomy and fault energy margin are both essential.

FAQ

Is the drain-to-tab connection electrically isolated in the BTS113AE3045ANTMA1?

No - Pin 2 (Drain) is internally bonded to the metal tab, making it electrically live at drain potential. This requires mandatory use of insulating mounting kits (e.g., mica washers + shoulder washers) when attaching to grounded heatsinks. Failure to isolate risks short-circuiting the load to chassis ground.

Can the temperature sensor be disabled or bypassed externally?

No - the thyristor-based temperature sensor is monolithically integrated and non-disableable. It activates autonomously at 150 °C and latches off until power cycle. There is no external pin, bias, or control signal to override or recalibrate the trip point; design must accommodate this fixed, hardware-enforced behavior.

What is the maximum allowable gate drive voltage for reliable operation?

The absolute maximum gate-source voltage is ±10 V per datasheet. Operation above +10 V risks permanent gate oxide damage; below –10 V may cause parasitic turn-on. Recommended drive is 4.5–10 V for full enhancement, with 5 V logic-level drive delivering typical R_DS(on) = 0.14 Ω and ensuring robust noise immunity in automotive environments.

Does the device meet AEC-Q101 qualification for automotive use?

Yes - BTS113AE3045ANTMA1 is fully qualified to AEC-Q101 Rev D for stress testing including HTGB, HTRB, AC/DC life test, and temperature cycling. The "E3045" suffix denotes AEC-Q101-compliant wafer fabrication and final test, and the "ANTMA1" tape-and-reel packaging meets automotive logistics requirements.
