Infineon Technologies BTS132E3045ANTMA1

Overview

BTS132E3045ANTMA1 from Infineon Technologies is an N-channel logic-level enhancement-mode Power MOSFET with integrated temperature-sensing thyristor (TEMPFET®), rated 60 V V_DS, 24 A I_D, and 0.065 Ω R_DS(on) at V_GS = 4.5 V, used for overtemperature-protected high-current switching in motor control and power supply output stages.

For engineers reviewing the BTS132E3045ANTMA1 datasheet, BTS132E3045ANTMA1 pinout, BTS132E3045ANTMA1 application, or BTS132E3045ANTMA1 equivalent, key selection criteria include its integrated thermal shutdown via thyristor latch, drain-to-tab electrical shorting, TO-220AB package thermal performance, and short-circuit robustness up to 80 A with 1200 W dissipation.

Technical Context

This TEMPFET® integrates a discrete N-channel MOSFET and a temperature-triggered thyristor on a single die. The thyristor activates at T_j ≥ 150 °C (V_TS = 5 V), latching the device OFF until gate reset - enabling autonomous, non-volatile overtemperature protection without external circuitry.

The MOSFET features logic-level gate drive (V_GS(th) = 1.5–2.5 V), low R_DS(on) (0.055 Ω typ.), and fast switching (t_on ≤ 240 ns, t_off ≤ 410 ns), with drain electrically connected to the metal tab for direct heatsinking and enhanced thermal transfer (R_thJC ≤ 1.67 K/W).

FAQ

What triggers the thyristor latch in BTS132E3045ANTMA1?

The thyristor activates when junction temperature reaches ≥150 °C under V_TS = 5 V bias, causing irreversible latch-OFF until gate voltage is removed and reapplied. This is a silicon-level thermal trip, independent of external sensors or control logic, and occurs within microseconds of reaching threshold.

Can BTS132E3045ANTMA1 be used in high-side switching configurations?

Yes - its drain-connected tab and isolated gate allow high-side use, but gate drive must provide floating bias referenced to drain potential. A bootstrap or isolated gate driver is required; the device itself does not integrate level-shifting circuitry.

Is the body diode suitable for freewheeling in inductive loads?

Yes - the integrated body diode has t_rr = 150 ns and Q_rr = 1.0 µC, optimized for fast recovery in PWM-driven inductive circuits like motor phases or solenoids, minimizing voltage spikes and switching losses.

Does the drain-to-tab shorting affect electrical isolation requirements?

Yes - Pin 2 (Drain) and the metal tab are electrically identical. Mounting requires either full electrical isolation (e.g., mica washer + thermal paste) or intentional connection to system ground/chassis if drain is grounded in the application topology.
