Product details
Overview
BAT750TA 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 50–1500mA, and 10ns reverse recovery time. It serves as a low-loss freewheeling or output rectifier in DC-DC converters for portable telecom and PCMCIA applications.
For engineers reviewing the BAT750TA datasheet, BAT750TA pinout, BAT750TA application, or BAT750TA equivalent, key selection criteria include its low VF at high current (e.g., 340mV @ 500mA), thermal resistance of 286°C/W on FR-4, and compatibility with lead-free reflow profiles per J-STD-020 Level 1.
Technical Context
The BAT750TA employs a planar Schottky junction structure optimized for fast switching and minimal conduction loss. Its 10ns trr and low CT (25pF @ 25V) support high-frequency operation up to several MHz in buck and boost topologies.
Designed for ambient temperatures from –55°C to +125°C, it delivers 0.75A average rectified current with derating above 25°C - maintaining 0.5A at 100°C per Fig. 5 - and withstands 5.5A non-repetitive surge current under 8.3ms half-sine conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - Maximum blocking voltage before avalanche; sets upper limit for input/output rail separation in DC-DC stages. |
| IF(AV) | 0.75 A - Continuous DC output current capability at 25°C ambient; defines usable load range in compact power supplies. |
| VF @ 500mA | 340 mV typical - Low conduction loss reduces heat generation and improves efficiency in battery-powered systems. |
| trr | 10 ns - Enables clean switching in >1 MHz converters without excessive ringing or EMI. |
| RθJA | 286 °C/W - Thermal resistance on standard FR-4 board; requires minimal copper area for thermal management. |
| CT @ 25V | 25 pF - Low junction capacitance minimizes switching losses and noise coupling in high-speed rectification. |
Pinout & Package
Package: SOT23 - 3-terminal surface-mount plastic package (2.9 × 1.35 × 1.025 mm), UL 94V-0 rated, matte tin-plated leads, moisture sensitivity level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Current entry point | Connected to switch node or inductor output; must handle peak forward surge (5.5A) and high di/dt. |
| Cathode (Pin 2) | Current exit point | Connected to output capacitor or ground return; low-inductance layout critical for EMI control. |
| NC / Heat Sink (Pin 3) | No internal connection | Unused terminal; may be grounded or left floating per layout requirements - no electrical function. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage | 225–475 mV across 50–1500 mA - directly reduces I²R losses and improves light-load efficiency in step-down regulators. |
| High conductance | Typical dynamic conductance >2.1 S at 500 mA - supports rapid turn-on and stable regulation during transient load steps. |
| Fast reverse recovery | 10 ns trr with 100 mA IF/IR - eliminates tail current, enabling clean zero-voltage switching in synchronous rectifier-assisted designs. |
| Lead-free & Green compliant | Halogen- and antimony-free (<900 ppm Br/Cl, <1000 ppm Sb); RoHS 3 compliant - meets automotive and consumer environmental mandates without performance trade-off. |
Applications
| DC-DC Buck Converter Output Rectifier | PCMCIA Card Power Switching |
|---|---|
Use Scenario: Used as secondary-side rectifier in 3.3V/5V buck converters powering baseband processors in mobile handsets. IC Role / Device Role / Timing Role: Freewheeling diode conducting during low-side switch off-time; defines minimum on-time and ripple amplitude. Use Value: 340 mV VF at 500 mA lowers conduction loss by ~40% vs. standard PN diodes, extending battery runtime. | Use Scenario: Provides hot-swap isolation and reverse-polarity protection in PCMCIA Type II card slots. IC Role / Device Role / Timing Role: Unidirectional current path enabling safe insertion/removal; blocks backfeed from host to card during power sequencing. Use Value: 40V VRRM accommodates 3.3V/5V rails with margin; 10ns trr prevents latch-up during fast edge transitions. |
| Mobile Telecom RF Power Amplifier Bias Supply | USB OTG Peripheral Power Path |
Use Scenario: Supplies bias current to GaAs FET drivers in 4G/LTE power amplifier modules with tight thermal constraints. IC Role / Device Role / Timing Role: Low-loss DC feed network component; conducts continuous 300–600 mA while rejecting RF leakage. Use Value: 25 pF CT at 25V minimizes RF shunting; 286°C/W RθJA allows direct mounting on RF shield without heatsink. | Use Scenario: Enables dual-role USB On-The-Go (OTG) devices to source or sink 500 mA from VBUS while preventing backdrive. IC Role / Device Role / Timing Role: Reverse-blocking path in power arbitration circuit; activated only during peripheral mode. Use Value: 0.75A rating exceeds USB 2.0 spec; 50 µA IR at 30V ensures negligible standby drain in battery-backed systems. |
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, higher IR (200µA @ 25V) | Limited to ≤3.3V systems; less suitable for 5V DC-DC outputs due to lower blocking voltage | Select when 30V rating suffices and lowest possible VF at light loads is prioritized |
| RB520S-30T2R | 45V VRRM, 320mV VF @ 500mA, 300mW PD, same SOT23-3L | Better surge robustness (IFSM = 8A); slightly higher VF increases conduction loss at full load | Prefer for industrial 5V/12V rails where overvoltage margin and surge immunity outweigh VF penalty |
Compared with SBAT54LT1G and RB520S-30T2R, the BAT750TA offers optimal balance of 40V blocking, sub-350mV VF at 500mA, and proven thermal performance on FR-4 - making it ideal for space-constrained, battery-sensitive telecom DC-DC designs.

FAQ
What is the maximum junction temperature for BAT750TA?
The BAT750TA has an operating junction temperature range of –55°C to +125°C. Its absolute maximum TJ is defined by thermal limits: at 25°C ambient, full 0.75A current is allowed; derating begins linearly above 25°C, reaching 0.5A at 100°C ambient per Fig. 5. Exceeding 125°C risks permanent parametric shift or failure.
Is BAT750TA qualified for automotive applications?
The BAT750TA is not AEC-Q101 qualified. While it operates across –55°C to +125°C and is manufactured in IATF 16949-certified facilities, Diodes explicitly states that automotive-grade versions require specific change control and PPAP capability - which this part does not carry. For automotive use, contact Diodes for AEC-Q101-compliant alternatives like the BAT750Q.
Can BAT750TA replace a standard PN rectifier in a 5V buck converter?
Yes - the BAT750TA replaces PN rectifiers such as 1N5819 in 5V buck converters, delivering measurable improvement: VF drops from ~450mV to ~340mV at 500mA, reducing conduction loss by ~35%, lowering die temperature, and improving light-load efficiency. No circuit redesign is needed, but layout must minimize parasitic inductance due to faster switching.
What is the recommended pad layout for BAT750TA in SOT23?
Diodes specifies a recommended SOT23 pad layout on its package-outlines webpage (diodes.com/package-outlines.html). Key dimensions include 0.9mm pad width, 1.35mm pad length, 0.89mm pitch between pins 1 and 2, and thermal relief for Pin 2 (cathode) to enhance solderability and thermal transfer. Use IPC-7351B generic SOT23 footprint unless Diodes' exact outline is applied.
