Product details

Overview

BTS282Z E3180A from Infineon Technologies is a Speed TEMPFET™ N-channel logic-level power MOSFET with integrated potential-free temperature sensor and thyristor-based overtemperature protection. It features 49 V V_DS, 6.5 mΩ R_DS(on) at V_GS = 10 V, 80 A continuous drain current (T_C = 100 °C), fast switching up to 1 MHz, and thermal trip at 150–170 °C. Used in automotive engine control modules for high-side load switching with real-time junction temperature monitoring.

For engineers reviewing the BTS282Z E3180A datasheet, BTS282Z E3180A pinout, BTS282Z E3180A application, or BTS282Z E3180A equivalent, key selection criteria include its dual-function integration (power switch + self-resetting temperature sensor), avalanche-rated ruggedness, ISO 10483-compliant 52 A nominal load current, and P-TO220-7-3 package with source-connected tab and dedicated sensor anode/cathode pins.

Technical Context

The BTS282Z integrates a vertical N-channel MOSFET and a monolithically embedded thyristor-based temperature sensor sharing no electrical connection to the power die - enabling "potential-free" sensing. Its gate threshold voltage (1.2–2.0 V) supports direct microcontroller drive without level-shifting, while the sensor's thermal trip point (150–170 °C) triggers latch-up at junction temperatures exceeding safe operating limits.

Switching performance is optimized for high-frequency PWM control: t_d(on) ≤ 45 ns, t_r ≤ 56 ns, Q_g(total) = 155–232 nC, and C_iss = 3850–4800 pF at 25 V. The integrated freewheeling diode delivers V_SD = 1.25–1.6 V at 95 A and t_rr = 105–157 ns, supporting efficient inductive load commutation.

Key Specifications

Parameter	Value and Actual Design Meaning
V_DS	49 V - Maximum blocking voltage for 12 V/24 V automotive systems with transient margin
R_DS(on)	6.5 mΩ @ V_GS = 10 V - Enables <1 W conduction loss at 40 A, reducing heatsink requirements
I_D(cont)	80 A @ T_C = 100 °C - Sustains high-current loads (e.g., fuel injectors, solenoids) without derating
E_AS	2 J - Avalanche energy rating ensures robustness against inductive switching stress without external snubbers
T_TS(on)	150–170 °C - Precise, repeatable thermal trip point for junction-overtemperature shutdown with self-reset capability
Q_g(total)	155–232 nC - Gate charge compatible with standard 1–2 A gate drivers for ≤1 MHz PWM operation
V_AK(on)	0.9–1.4 V @ I_AK = 1.5–5 mA - Low forward voltage enables low-power sensor biasing and accurate analog temperature readout

Pinout & Package

P-TO220-7-3 package with isolated tab (drain-connected), 7-pin through-hole mounting, and 3-source pins for low-inductance parallel conduction paths.

3	Anode (A) - Temperature Sensor	Thyristor anode terminal; used with external resistor to bias sensor into conduction above trip temperature
4 + TAB	Drain (D)	Main power output path; tab is electrically connected to drain and serves as primary thermal interface
5	Cathode (K) - Temperature Sensor	Thyristor cathode; forms sensing node with Pin 3; reset pulse applied here to restore normal operation

Key Features

Feature	Design Value

Alternative Part	Technical Difference	Application Difference	Selection Advice
BTS282L E3180A	Same die, P-TO220-7-180 package with bent leads and different thermal pad layout	Designed for automated through-hole insertion; identical electrical specs but altered mechanical mounting	Select when board assembly uses wave soldering or requires lead-forming compatibility

FAQ

What is the thermal trip mechanism of the BTS282Z E3180A?

The device uses a monolithic thyristor-based temperature sensor with no electrical connection to the MOSFET die. When junction temperature exceeds 150–170 °C, the sensor latches on, pulling the gate low via internal circuitry to shut off the MOSFET. A reset pulse applied to Pin 5 (K) restores operation within 150 µs.

Can the BTS282Z E3180A be used in parallel configurations?

Yes - its positive temperature coefficient of R_DS(on) and three dedicated source pins enable stable current sharing. However, individual gate resistors (≤1.5 Ω) and matched PCB trace lengths are required to ensure simultaneous switching and prevent dynamic current imbalance.

Does the integrated temperature sensor provide analog output?

No - it is a digital latch-type sensor. The anode (Pin 3) and cathode (Pin 5) form a thyristor that conducts only above trip temperature. Analog temperature measurement is not supported; the device provides overtemperature protection, not proportional sensing.

What is the maximum recommended PCB copper area for thermal performance?

For optimal thermal resistance, use a minimum 6 cm² copper pour (single layer, 70 µm thick) connected to the drain tab. This achieves R_th(JA) = 33–40 K/W. Smaller areas increase junction temperature significantly - e.g., 1 cm² raises R_th(JA) to ~62 K/W per datasheet.
