Product details
Overview
BSP75GQTA from Diodes Incorporated is a self-protected low-side IntelliFET® MOSFET switch rated for 60V drain-source voltage, 550 mΩ typical RDS(ON) at VIN = 5V, and 1.4A nominal load current. It integrates monolithic overtemperature, overcurrent, active overvoltage clamping (VDS(AZ) = 60–75V), ESD (4 kV HBM), and load-dump protection (80V), and is AEC-Q101 qualified for automotive relay replacement in 12V/24V DC systems.
For engineers reviewing the BSP75GQTA datasheet, BSP75GQTA pinout, BSP75GQTA application, or BSP75GQTA equivalent, this page delivers verified thermal shutdown behavior, logic-level input compatibility (VIN(TH) = 1–2.1V), unclamped inductive energy rating (EAS = 550 mJ), and SOT223 package thermal resistance (RθJA = 24°C/W with adequate copper).
Technical Context
The BSP75GQTA operates as a protected low-side power switch with integrated fault management: its active clamp limits VDS to ≤75V during transients, while current-limiting protection deactivates below 5V VDS to preserve normal-load conduction. Thermal shutdown triggers at TJ = +150°C to +175°C with +10°C hysteresis, enabling auto-restart after cooldown.
It supports logic-level drive (VIN = 0–10V), exhibits fast switching (tON = 2.2 μs, tOFF = 13 μs), and maintains safe operation under high in-rush loads-evidenced by its 550 mJ EAS rating and linear-mode capability up to thermal limits of the SOT223 board layout.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VDS max | 60 V - Maximum continuous drain-source blocking voltage before breakdown |
| RDS(ON) | 520–675 mΩ @ VIN = 5V - On-resistance defining I2R conduction loss at nominal logic drive |
| ID (nominal) | 1.4 A @ VIN = 5V - Continuous load current limited by thermal design, not protection circuitry |
| EAS | 550 mJ @ TJ = 25°C - Energy-handling capacity during unclamped inductive turn-off, critical for motor/lamp snubbing |
| VLOAD_DUMP | 80 V - Active protection against ISO 7637-2 Load Dump transients without external TVS |
| VESD (HBM) | 4000 V - Robustness against human-body electrostatic discharge during handling and assembly |
| TJ range | −40°C to +150°C - Full operational junction temperature range compliant with AEC-Q101 stress testing |
Pinout & Package
Package: SOT223 (Type DN), surface-mount, thermally enhanced with drain-connected tab requiring electrical isolation from source and recommended copper pour for RθJA = 24°C/W performance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 (Source) | Power return path for load current | Low-impedance ground reference; must be isolated from drain tab; connects to system GND |
| Pin 2 (Gate) | Logic-level control input | Accepts 0–10V drive; threshold VIN(TH) = 1–2.1V enables direct µC interfacing |
| Pin 3 (Drain) | Main power output terminal | High-side load connection point; tab is internally bonded to this pin for thermal conduction |
| Tab (Drain) | Thermal and electrical extension of drain | Must be electrically isolated from source; copper area improves heat dissipation and lowers RθJA |
Key Features
| Feature | Design Value |
|---|---|
| Short-circuit protection with auto restart | Prevents latch-up during sustained overload; recovers automatically after fault removal and cooling |
| Active overvoltage clamp | Clamps VDS to 60–75V during transients-eliminates need for external Zener or TVS diode |
| Thermal shutdown with hysteresis | Trips at +150°C to +175°C and resets only after ≥10°C cooldown-avoids oscillation near limit |
| Load dump protection | Withstands 80V ISO 7637-2 pulses without external components-critical for automotive 12V/24V systems |
| Logic-level input compatibility | VIN(TH) ≤ 2.1V allows direct interface with 3.3V/5V microcontrollers without level-shifting |
Applications
| Automotive Lighting Control | DC Motor Starter Circuits |

Equivalent & Alternatives
The following parts are listed as comparable options for similar low-side protected MOSFET switch applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| INFINEON BTS716G | Higher RDS(ON) (800 mΩ), lower ID (1.0A), no active clamp (only passive clamp), same SOT223 package | Limited to lower-power resistive loads; requires external TVS for load dump compliance | Select when cost sensitivity outweighs transient robustness and higher current capability is unnecessary |
| ON SEMI NCV8460A | Lower VDS (40V), higher RDS(ON) (900 mΩ), identical protection architecture and AEC-Q101 qualification | Suitable only for 12V systems; insufficient for 24V industrial or commercial truck applications | Choose for compact 12V-only designs where 60V margin is not required and footprint compatibility is critical |
Compared with BTS716G and NCV8460A, the BSP75GQTA provides superior 60V robustness, lower on-resistance, and integrated 80V load dump protection-making it the optimal choice for 24V automotive and industrial systems demanding single-component fault resilience.

FAQ
What is the maximum continuous current the BSP75GQTA can deliver in a standard SOT223 PCB layout?
The BSP75GQTA delivers 1.4A continuously at VIN = 5V under standard test conditions (37mm × 37mm × 1.6mm FR-4 with 2oz copper). Its actual current capability scales with thermal design: with optimized copper pour, RθJA drops to 24°C/W, allowing >2A before thermal shutdown at +85°C ambient.
Does the BSP75GQTA require an external flyback diode when driving inductive loads?
No external flyback diode is required. The device's 550 mJ unclamped inductive energy rating (EAS) and integrated active clamp allow safe turn-off of inductive loads like solenoids and motors without external snubbing components-provided layout minimizes parasitic inductance.
How does the BSP75GQTA behave during ISO 7637-2 Load Dump events?
During an 80V, 100ms Load Dump pulse, the BSP75GQTA's active clamp engages to hold VDS within safe limits, preventing damage. Its internal protection remains fully functional without derating or external components-verified per AEC-Q101 stress requirements.
Can the BSP75GQTA be used in linear mode for current regulation?
Yes-the current-limiting circuitry deactivates below 5V VDS, enabling stable linear-mode operation. Maximum DC current is determined solely by thermal limits (e.g., 2.5W PD at TA = 25°C), not protection thresholds, making it suitable for precision current-source applications with proper heatsinking.
