Product details
Overview
BAT750-7-F from Diodes Incorporated is a 0.75A surface-mount Schottky barrier rectifier in SOT23 package, featuring 40V peak repetitive reverse voltage, 225–475mV forward voltage at 50–750mA, and 10ns reverse recovery time. It serves as a low-loss power rectifier in DC-DC converter outputs, PCMCIA card power rails, and mobile telecom battery charging paths.
For engineers reviewing the BAT750-7-F datasheet, BAT750-7-F pinout, BAT750-7-F application, or BAT750-7-F equivalent, key selection criteria include forward voltage at target load current, thermal resistance (286°C/W), reverse leakage (<100µA at 30V), junction temperature range (–55°C to +125°C), and SOT23 footprint compatibility with high-density PCB layouts.
Technical Context
The BAT750-7-F employs a planar Schottky junction structure optimized for low VF and fast switching, enabling efficient unidirectional conduction in low-voltage, high-frequency power conversion stages. Its 10ns trr and <175pF capacitance at 0V support operation up to several MHz in synchronous rectifier or freewheeling roles.
Thermal performance is defined by RθJA = 286°C/W on FR-4 with recommended pad layout, limiting continuous current to 0.75A at TA = 25°C; derating begins above 25°C per Fig. 5. The device is rated for –55°C to +125°C operating temperature and complies with AEC-Q101 for automotive-qualified variants (though BAT750-7-F itself is standard industrial grade).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Peak Reverse Voltage | 40 V - supports input/output isolation in 24V and lower DC-DC systems without breakdown risk |
| Forward Voltage | 225 mV @ 50 mA - enables ultra-low conduction loss in standby or light-load conditions |
| Avg. Rectified Current | 0.75 A - defines maximum continuous DC output current under specified thermal conditions |
| Reverse Recovery Time | 10 ns - minimizes switching loss and EMI in high-frequency buck or boost converters |
| Thermal Resistance | 286 °C/W - requires careful PCB copper area design to maintain TJ < 125°C at full load |

Applications
| DC-DC Converter Output Rectification | PCMCIA Card Power Management |
|---|---|
Use Scenario: Secondary-side rectification in 3.3V/5V buck converters powering baseband processors or RF modules. IC Role / Device Role / Timing Role: Unidirectional current valve replacing synchronous MOSFETs where gate drive complexity must be minimized. Use Value: 225–350mV VF at 100–500mA lowers conduction loss by 0.225–1.75W vs. 0.7V silicon diodes, improving efficiency by 2–5% at light-to-moderate loads. | Use Scenario: Reverse polarity protection and hot-swap isolation for 3.3V/5V PCMCIA Type II card slots in laptops and docking stations. IC Role / Device Role / Timing Role: Low-VF series blocking diode preventing backfeed from card to host during insertion/removal. Use Value: 100µA max IR at 30V ensures negligible standby current drain; SOT23 footprint fits tight card-edge spacing constraints. |
| Mobile Telecom Battery Charging Path | Low-Power IoT Sensor Node Power Rail |
Use Scenario: OR-ing diode in dual-input (USB + battery) charging circuits for smartphones and wearables. IC Role / Device Role / Timing Role: Prevents reverse current flow from battery to USB port while minimizing voltage drop across charging path. Use Value: 280–420mV VF at 500–750mA limits voltage loss to ≤42mV at 150mA, preserving battery runtime and charge termination accuracy. | Use Scenario: Supply isolation between coin-cell backup and main LDO in ultra-low-power environmental sensors. IC Role / Device Role / Timing Role: Leakage-suppressing diode ensuring nanowatt-level quiescent current in deep-sleep mode. Use Value: 50µA typical IR at 30V prevents >1.5µA parasitic discharge-critical for multi-year battery life in LoRaWAN/NB-IoT nodes. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Same SOT23 package; 30V VRRM, 240mV VF @ 100mA, 2A IFSM | Limited to ≤30V systems; higher surge rating suits transient-prone inputs | Select when system reverse voltage ≤30V and surge immunity is prioritized over voltage margin |
| NSR0230HT1G | 0.2A IO rating, 30V VRRM, 270mV VF @ 100mA, SOD-123 package | Lower current capacity; smaller footprint but no thermal pad option | Choose for space-constrained 100mA applications where SOT23 thermal mass is unnecessary |
Compared with SBAT54LT1G and NSR0230HT1G, the BAT750-7-F delivers higher reverse voltage margin (40V), greater average current (0.75A), and superior thermal dissipation via SOT23's inherent copper exposure-making it optimal for 24V-input DC-DC secondaries and industrial-grade portable power rails.

FAQ
Is BAT750-7-F qualified for automotive applications?
No, BAT750-7-F is an industrial-grade part. Diodes offers AEC-Q101-qualified variants (e.g., BAT750Q-7-F) with PPAP documentation and IATF 16949 manufacturing, but this specific part number lacks automotive qualification and change control.
What is the maximum allowable junction temperature during operation?
The BAT750-7-F has a maximum junction temperature of +125°C. At ambient temperatures above 25°C, average current must be derated per Fig. 5; for example, at TA = 85°C, IO is limited to approximately 0.45A with the standard FR-4 pad layout.
Can BAT750-7-F replace a standard silicon diode in a 5V supply?
Yes-its 40V VRRM and low VF make it suitable for 5V rectification, reducing conduction loss significantly. However, ensure reverse voltage transients do not exceed 40V, and verify thermal design since Schottky leakage rises faster with temperature than silicon.
Does BAT750-7-F have a built-in thermal pad or exposed cathode?
No. Pin 3 in the SOT23 package is unconnected (NC). The cathode (Pin 2) is electrically active but not thermally enhanced; thermal performance relies entirely on PCB copper area connected to Pins 1 and 2 per Diodes' recommended pad layout.
