Product details

Overview

BTS113ANKSA1 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 body electronics for short-circuit-protected load switching.

For engineers reviewing the BTS113ANKSA1 datasheet, BTS113ANKSA1 pinout, BTS113ANKSA1 application, or BTS113ANKSA1 equivalent, key selection criteria include its integrated thermal shutdown via thyristor-triggered latch, drain-to-tab electrical shorting, TO-220AB package thermal performance, and ISO-rated 2.2 A current capability at 85 °C.

Technical Context

This device integrates a power MOSFET and a temperature-sensing thyristor on a single die: the thyristor latches when junction temperature exceeds ~150 °C (V_TS = 5 V), forcing gate-source short and disabling conduction. The drain is electrically connected to the metal tab for direct heatsinking and low-inductance layout.

It operates as a self-protecting high-side or low-side switch with built-in short-circuit protection: under fault, it limits dissipation to ≤400 W for up to 20 ms before triggering thyristor latch, with typical turn-on/turn-off times of 70 ns and 105 ns respectively at V_GS = 5 V, I_D = 3 A.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	60 V - supports 12 V automotive systems with margin for load dump transients
I_D (continuous, T_C = 25 °C)	11.5 A - enables driving high-current solenoids or lamps without external heatsink
R_DS(on) (V_GS = 4.5 V)	0.17 Ω max - ensures <1.5 W conduction loss at 11.5 A, critical for thermally constrained modules
T_TS(on)	150 °C - precise silicon-based thermal trip point, independent of PCB layout or external sensors
t_SC(off)	20 ms - defined response window for short-circuit energy limiting before thyristor activation
V_SD (I_F = 11.5 A)	1.6 V max - forward diode drop impacts freewheeling efficiency in inductive loads
I_H (T_j = 150 °C)	0.3 A - holding current threshold ensuring stable thyristor latch during overtemperature events

Pinout & Package

TO-220AB package with isolated mounting hole; drain (D) electrically connected to metal tab for direct thermal coupling and low-impedance return path.

Pin/Terminal	Circuit Role	Design Meaning
1 (Gate)	Control input	Logic-level compatible (V_GS(th) = 1.6–2.5 V); requires <100 nA leakage at 150 °C
2 (Drain)	Power output / High-side switch node	Electrically shorted to metal tab - must be insulated from chassis unless referenced to system ground
3 (Source)	Power return / Low-side reference	Provides common return for MOSFET channel and internal thyristor cathode; defines V_GS reference

Key Features

Feature	Design Value
Integrated temperature-sensing thyristor	Latches at 150 °C with 0.5–2.5 µs turn-off time, eliminating need for external thermal IC or NTC circuit
Drain-to-tab connection	Enables direct mechanical mounting to heatsink with minimal thermal resistance (R_thJC ≤ 3.1 K/W)
Logic-level gate drive	Operates fully enhanced at V_GS = 4.5 V - compatible with 3.3 V and 5 V microcontrollers without level-shifting
Short-circuit energy rating	400 W for 20 ms - allows safe interruption of >27 A faults in automotive 12 V systems
Reverse diode rating	11.5 A continuous source current with 1.6 V V_SD - supports bidirectional inductive load commutation

Applications

Automotive Door Module

Engine Bay Fan Control

Use Scenario: Driving power windows, locks, and mirrors in centralized door control units exposed to ambient temperatures up to 85 °C.

IC Role / Device Role: High-side load switch with integrated thermal cutoff to prevent module damage during motor stall or wiring shorts.

Use Value: Eliminates discrete thermal fuse and sense resistor, reducing BOM count by two components while improving trip accuracy vs. PCB-trace-based thermal sensing.

Use Scenario: Controlling brushed DC cooling fans near hot engine components where junction temperature may exceed 130 °C during idle-stop cycles.

IC Role / Device Role: Self-protecting low-side switch that latches off above 150 °C and remains disabled until power cycle.

Use Value: Prevents fan controller failure due to sustained overtemperature - no software polling or external monitoring required.

Truck Lighting System

Industrial HVAC Actuator

Use Scenario: Switching high-intensity LED headlamp arrays subject to load-dump transients up to 60 V and thermal cycling from –40 °C to +105 °C.

IC Role / Device Role: Robust N-channel driver with 60 V V_DS rating and integrated reverse diode for inductive spike suppression.

Use Value: Withstands ISO 7637-2 Pulse 5a without external TVS, reducing board space and transient protection cost.

Use Scenario: Controlling 24 V DC damper motors in commercial HVAC panels installed in ceiling plenums with limited airflow.

Equivalent & Alternatives

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

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS114ANKSA1	Higher R_DS(on) (0.22 Ω), same V_DS/I_D/T_TS(on); identical pinout and thermal behavior	Suitable where lower conduction loss is not critical but higher short-circuit robustness is needed (P_SCmax = 450 W)	Select when prioritizing fault energy margin over efficiency in intermittent-duty loads
IPB113N10N3G	No integrated temperature sensor; 100 V V_DS, 0.0095 Ω R_DS(on), TO-263 package; requires external thermal protection	Used in high-efficiency, high-voltage industrial motor drives where discrete thermal management is already present	Choose only if thermal sensing is handled separately and lower R_DS(on) justifies added design complexity

Compared with BTS114ANKSA1, BTS113ANKSA1 offers lower conduction loss and faster thermal response; versus IPB113N10N3G, it trades voltage headroom and R_DS(on) for autonomous thermal safety - critical where firmware-based protection is unreliable or unavailable.

FAQ

What triggers the thyristor latch in BTS113ANKSA1?

The thyristor activates when junction temperature reaches approximately 150 °C under V_TS = 5.0 V bias, causing irreversible gate-source shorting. It does not reset automatically - power must be cycled to restore operation. This behavior is confirmed across T_j = –55 °C to +160 °C per datasheet Figure 12.

Can BTS113ANKSA1 be used in high-side configuration?

Yes - its drain-connected tab allows direct high-side mounting to chassis ground, provided the gate driver is referenced to source potential. Gate threshold (1.6–2.5 V) and logic-level compatibility enable use with standard microcontroller GPIOs when paired with appropriate level-shifting or isolated gate drive.

How does the integrated diode affect freewheeling in inductive loads?

The body diode supports 11.5 A continuous reverse current with 1.6 V forward drop at rated current. Its 60 ns reverse recovery time and 0.10 µC Q_rr minimize switching losses and voltage overshoot during turn-off - validated in automotive solenoid drive waveforms per datasheet Section 4.3.

Is the drain-to-tab connection insulated in TO-220AB packaging?

No - the drain is electrically shorted to the metal tab per datasheet Feature "The drain pin is electrically shorted to the tab". Mounting requires insulating hardware (e.g., mica washer + shoulder washer) unless the tab is intentionally tied to drain potential in the PCB layout.
