Product details
Overview
BTS114AE3045A from Infineon Technologies is an N-channel enhancement-mode TEMPFET® power MOSFET with integrated temperature-sensing thyristor, rated for 50 V VDS, 17 A continuous drain current at TC = 27 °C, and 0.10 Ω RDS(on) at VGS = 10 V. It features electrically shorted drain-to-tab construction and is used in overtemperature-protected DC motor drives and industrial load switches.
For engineers reviewing the BTS114AE3045A datasheet, BTS114AE3045A pinout, BTS114AE3045A application, or BTS114AE3045A equivalent, key selection factors include its integrated thermal shutdown via thyristor latch, drain-to-tab thermal path, short-circuit withstand capability (550 W, 25 ms), and gate threshold voltage stability across –55 to +150 °C.
Technical Context
This device integrates a power MOSFET and a temperature-triggered thyristor on a single die. The thyristor activates when junction temperature exceeds ~150–160 °C, latching the gate low and forcing the MOSFET into safe-off state-enabling autonomous, self-resetting overtemperature protection without external circuitry.
Its TO-220AB package provides direct thermal coupling from chip to heatsink via the electrically active drain tab. Electrical isolation between gate and drain is maintained by design, while the integrated reverse diode supports freewheeling in inductive loads with trr ≤ 60 ns and Qrr ≤ 0.10 µC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 50 V - Maximum blocking voltage before avalanche; defines use in ≤48 V DC systems. |
| ID (continuous) | 17 A at TC = 27 °C - Sustained load current capability with adequate heatsinking. |
| RDS(on) | 0.10 Ω max at VGS = 10 V - Conduction loss of ≤2.89 W at 17 A, enabling efficient switching in high-current paths. |
| Tj range | –55 to +150 °C - Validated operation across automotive under-hood and industrial ambient extremes. |
| trr / Qrr | ≤60 ns / ≤0.10 µC - Enables fast turn-off in inductive switching with low recovery loss and EMI. |
| VTS(on) | 1.4–1.5 V at ITS(on) = 10 mA - Stable forward voltage of integrated temperature sensor, used for thermal monitoring and latch triggering. |
| tSC(off) | 25 ms - Guaranteed response time to short-circuit event before thermal runaway occurs. |
Pinout & Package
Package: TO-220AB (3-pin, straight lead, drain-connected tab). Tab is electrically connected to Pin 1 (Drain) per datasheet Figure 1 and "drain pin is electrically shorted to the tab" statement.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Tab) | Drain (D) | Electrically tied to internal drain; serves as primary thermal and current path to heatsink. |
| Pin 2 | Source (S) | Reference node for gate drive and load return; carries full load current and reverse diode conduction. |
| Pin 3 | Gate (G) | Control input; requires 2.5–3.5 V threshold and ±20 V absolute max rating; isolated from drain by oxide. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated thyristor-based thermal protection | Latches off MOSFET autonomously at Tj ≥ ~150–160 °C; resets only after cooldown and gate re-enable. |
| Drain-to-tab connection | Minimizes thermal resistance (RthJC ≤ 2.5 K/W); enables direct mounting to heatsink without insulator. |
| Low RDS(on) with stable VGS(th) | 0.10 Ω max with <±0.5 V drift over –55 to +150 °C-ensures predictable turn-on across temperature. |
| Fast-recovery body diode | trr ≤ 60 ns, Qrr ≤ 0.10 µC-reduces switching loss and voltage overshoot in flyback/inductive loads. |
| Short-circuit ruggedness | Withstands 37 A ISC for 25 ms at 50 W dissipation-supports fault-tolerant motor control and solenoid drivers. |
Applications
| DC Motor Protection Circuit | Industrial Load Switch |

Equivalent & Alternatives
The following parts are listed as comparable options for similar temperature-protected power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS114N3E3045A | Same die, but N-channel logic-level variant with VGS(th) = 1.0–2.0 V; RDS(on) = 0.09 Ω typ. | Enables direct microcontroller GPIO drive without level-shifting; lower gate charge improves switching efficiency. | Select when gate drive voltage is ≤5 V and faster switching is prioritized over maximum thermal margin. |
| IPB114N20N3G | 200 V-rated N-channel TrenchMOS with no integrated temperature sensor; RDS(on) = 0.0055 Ω; TO-263 package. | Higher voltage rating and lower RDS(on), but requires external thermal protection circuitry. | Select for 100–200 V systems where autonomous thermal shutdown is implemented separately. |
Compared with BTS114N3E3045A, this part offers higher gate threshold robustness against noise but requires 10 V drive; versus IPB114N20N3G, it trades voltage headroom and ultra-low RDS(on) for monolithic thermal safety-critical in space-constrained, unattended industrial nodes.

FAQ
What is the function of the thyristor in BTS114AE3045A?
The integrated thyristor acts as a temperature-triggered latch: when junction temperature reaches ~150–160 °C, it fires and shorts the gate to source, forcing the MOSFET into permanent off-state until power is cycled and gate is actively re-driven. This provides autonomous, irreversible thermal shutdown without external components.
Can BTS114AE3045A be used in high-side switching configurations?
Yes-it supports high-side switching when driven with appropriate level-shifted gate control (e.g., bootstrap or isolated gate driver), as its gate-source voltage rating is ±20 V and drain is referenced to the tab. The drain-connected tab simplifies heatsinking but requires electrical isolation from ground if mounted directly to chassis.
Is the body diode suitable for continuous freewheeling current?
Yes-the integrated body diode is rated for 17 A continuous source current (IS) and 68 A pulsed (ISM). Its 1.3–1.6 V forward drop at 17 A and 60 ns reverse recovery time make it suitable for moderate-frequency inductive freewheeling in motor and solenoid drivers.
Does BTS114AE3045A meet AEC-Q101 qualification?
Yes-BTS114AE3045A is AEC-Q101 qualified per Infineon's official documentation (Product Brief BTS114A, Rev. 2.0, 2021), including stress tests for temperature cycling, humidity, and high-temperature operating life-validating suitability for automotive under-hood applications.
