Product details
Overview
BTS114AE3045ANTMA1 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, used in overtemperature-protected DC motor drives and industrial load switches.
For engineers reviewing the BTS114AE3045ANTMA1 datasheet, BTS114AE3045ANTMA1 pinout, BTS114AE3045ANTMA1 application, or BTS114AE3045ANTMA1 equivalent, key selection criteria include its integrated thermal shutdown via thyristor latch, drain-tab shorting for low-inductance heatsinking, and short-circuit withstand capability up to 550 W for 25 ms.
Technical Context
This device combines a logic-level-compatible power MOSFET with a monolithically integrated silicon temperature sensor exhibiting thyristor latching behavior above ~150 °C - enabling self-triggered, irreversible overtemperature shutdown without external circuitry. The gate threshold voltage (2.5–3.5 V) and low RDS(on) support direct microcontroller drive and high-efficiency switching at 17 A.
Its thermal protection operates independently of gate control: once triggered by junction temperature exceeding TTS(on), the thyristor clamps VGS near zero and holds the MOSFET off until power cycle reset. Short-circuit response time is 25 ms at Tj = 25 °C, with ISC rated at 37 A under defined VDS/VGS conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS | 50 V - maximum blocking voltage before avalanche; defines safe operating range in 24 V industrial systems. |
| ID (continuous) | 17 A at TC = 27 °C - usable continuous load current with standard TO-220 heatsinking. |
| RDS(on) | 0.10 Ω max at VGS = 10 V - enables ≤1.7 W conduction loss at 17 A, critical for thermal management. |
| TTS(on) | Not specified - thyristor latching occurs at Tj ≈ 150–160 °C per override test condition; provides hard thermal cutoff. |
| tSC(off) | 25 ms - guaranteed short-circuit response time before thermal runaway, independent of gate drive. |
| VSD | 1.6 V max at IF = 17 A - forward voltage of integrated body diode; impacts freewheeling losses in inductive loads. |
| Qrr | 0.10 µC - reverse recovery charge of body diode; determines switching loss and EMI in hard-switched topologies. |
Pinout & Package
Package: TO-220AB (standard 3-pin through-hole, drain-connected tab). Pin 1 = Gate, Pin 2 = Drain (electrically connected to metal tab), Pin 3 = Source.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Gate) | Control terminal | Accepts 0–10 V logic-level drive; threshold 2.5–3.5 V ensures compatibility with 3.3 V/5 V MCUs. |
| Pin 2 (Drain) | High-side power path | Internally shorted to metal tab - enables low-thermal-resistance mounting to heatsink without insulator. |
| Pin 3 (Source) | Reference node | Serves as return path for load current and gate drive reference; must be routed with low inductance. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated thyristor-based thermal shutdown | Self-latching protection at Tj ≥ 150 °C eliminates need for external thermal IC or NTC + comparator. |
| Drain-to-tab shorting | Reduces thermal resistance to heatsink (RthJC ≤ 2.5 K/W) and simplifies mechanical mounting. |
| Low gate threshold voltage | VGS(th) = 2.5–3.5 V allows direct drive from standard microcontrollers without level-shifting. |
| Short-circuit withstand capability | Rated for 37 A ISC and 550 W PSCmax for 25 ms - supports robust fault handling in motor stall events. |
Applications
| DC Motor Protection | Industrial Load Switch |
|---|---|
Use Scenario: 24 V brushed DC motor driver in factory automation where stall currents exceed 15 A. IC Role / Device Role / Timing Role: Main power switch with built-in thermal cutoff; latches off during rotor jam or winding overheat. Use Value: Prevents MOSFET destruction and wiring insulation damage by cutting power within 25 ms of short-circuit onset. | Use Scenario: High-reliability solenoid actuator control in valve manifolds exposed to ambient >85 °C. IC Role / Device Role / Timing Role: Load switch with autonomous thermal derating - shuts down before junction exceeds 160 °C. Use Value: Eliminates need for separate temperature monitoring circuitry, reducing BOM count and board area. |
| Overtemperature-Safe Power Supply | Heater Element Control |
Use Scenario: 48 V telecom power distribution unit supplying fan modules with variable airflow demand. IC Role / Device Role / Timing Role: Current-limiting switch with fail-safe thermal lockout; remains off until power cycle reset. Use Value: Guarantees single-point failure mode (open-circuit) during overheating, meeting IEC 62368-1 safety requirements. | Use Scenario: Precision resistive heater control in medical diagnostic equipment requiring thermal run-away prevention. IC Role / Device Role / Timing Role: Power stage with intrinsic temperature sensing - thyristor triggers at fixed Tj, not ambient. Use Value: Provides junction-level thermal protection independent of heatsink contact quality or airflow variation. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar overtemperature-protected power switching applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| BTS114N10E3045ANTMA1 | Same package and thermal shutdown function but 100 V VDS rating and 0.09 Ω RDS(on). | Supports higher bus voltages (e.g., 48 V systems with surge margin); slightly lower conduction loss. | Select when system Vbus exceeds 40 V or efficiency at 15–20 A is prioritized. |
| IPD95R1K2P7ATMA1 | 950 V Si MOSFET with no integrated temperature sensor; requires external thermal protection circuit. | Designed for high-voltage AC-DC PFC stages, not thermal-fail-safe DC loads. | Only suitable if thermal monitoring is implemented separately and VDS > 50 V is mandatory. |
Compared with BTS114N10E3045ANTMA1, this part trades voltage headroom for tighter thermal specification compliance at 50 V; versus IPD95R1K2P7ATMA1, it delivers autonomous thermal safety without added components or design complexity.

FAQ
Does BTS114AE3045ANTMA1 require external components to enable thermal protection?
No. The integrated thyristor provides autonomous, self-latching thermal shutdown at junction temperatures ≥150–160 °C. No external NTC, comparator, or latch circuit is needed - protection activates directly upon overtemperature event and persists until power removal.
Can the thermal shutdown be disabled or adjusted?
No. The thyristor-based thermal protection is monolithic and non-adjustable. It triggers irreversibly at a fixed junction temperature range (150–160 °C) and requires full power cycle reset. This design ensures predictable, fail-safe behavior per safety standards.
What is the significance of drain-to-tab shorting in TO-220AB package?
The drain pin is electrically bonded to the metal tab, enabling direct low-thermal-resistance mounting to a heatsink without insulating pads. This reduces RthJC to ≤2.5 K/W and avoids gate-drain capacitance increase caused by isolation layers.
Is BTS114AE3045ANTMA1 suitable for PWM motor control?
Yes - with verified 68 A pulsed drain current and 40–60 ns turn-off time, it supports PWM frequencies up to ~20 kHz in 24 V DC motor drives. However, body diode Qrr = 0.10 µC necessitates snubber design or synchronous rectification for optimal efficiency.
