Product details
Overview
BAT760Q-7 from Diodes Incorporated is a surface-mount Schottky barrier rectifier in SOD-323 package, rated for 30 V peak repetitive reverse voltage, 1 A average rectified output current, and 245–495 mV forward voltage drop at 10–1000 mA. It features guard ring construction for transient protection and is optimized for low-voltage, high-efficiency DC power conversion in space-constrained portable electronics.
For engineers reviewing the BAT760Q-7 datasheet, BAT760Q-7 pinout, BAT760Q-7 application, or BAT760Q-7 equivalent, key selection criteria include its low VF at low IF, tight IR specification (≤5 µA at VR = 15 V), SOD-323 thermal resistance (RJA = 426 °C/W), and RoHS-compliant matte tin finish on Alloy 42 leadframe.
Technical Context
This Schottky rectifier operates as a unidirectional, single-phase, half-wave AC-to-DC converter with no minority-carrier storage delay. Its guard ring structure enhances ruggedness against voltage transients, while the low junction capacitance (25 pF at 5 V) supports high-frequency switching applications up to several MHz.
Thermal performance is defined by 235 mW power dissipation and 426 °C/W junction-to-ambient thermal resistance under standard FR-4 mounting. Derating is required for capacitive loads (−20% IO) and elevated ambient temperatures per Fig. 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum non-repetitive reverse voltage before breakdown; defines safe operating limit in flyback or clamp circuits. |
| IO | 1 A - Continuous DC output current capability at 25 °C ambient; derated linearly above 25 °C per Fig. 1. |
| VF @ 100 mA | 350 mV typical - Enables <100 mW conduction loss at 100 mA, critical for battery-powered efficiency. |
| IR @ 15 V | 50 µA max - Low leakage preserves standby power in always-on circuits such as USB charging ports. |
| CT | 25 pF @ 1 MHz, 5 V - Supports fast switching in 1–10 MHz DC/DC converters without excessive ringing. |
| RJA | 426 °C/W - Requires minimal copper area on FR-4; limits junction temperature rise to ~100 °C at 1 A in still air. |
Pinout & Package
Package: SOD-323 - ultra-small plastic surface-mount case (2.3–2.7 mm × 1.6–1.8 mm × 1.2–1.4 mm), UL 94V-0 rated, moisture sensitivity Level 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode | Current entry terminal during forward conduction | Connected to lower-potential side (e.g., ground or return path) in reverse polarity protection. |
| Cathode (marked with band) | Current exit terminal during forward conduction | Connected to input supply rail; band orientation enables automated optical inspection and pick-and-place alignment. |
Key Features
| Feature | Design Value |
|---|---|
| Very low forward voltage drop | VF = 245–550 mV across 10–1000 mA - reduces conduction loss by >40% vs. standard silicon diodes at same current. |
| Guard ring construction | Integrated edge termination - improves surge robustness (IFSM = 5.5 A) and prevents premature edge breakdown under transient overvoltage. |
| Lead-free / RoHS compliant | Matte tin annealed over Alloy 42 - ensures solderability per MIL-STD-202 and eliminates Pb-related reliability concerns in consumer-grade assemblies. |
| Low junction capacitance | CT = 25 pF @ 5 V - minimizes switching losses and EMI in high-frequency buck or boost regulators. |
Applications
| USB Power Delivery Protection | Low-Voltage DC/DC Output Rectification |
|---|---|
Use Scenario: Reverse polarity and overvoltage protection in 5 V USB Type-C power paths. IC Role / Device Role: Unidirectional blocking diode placed between source and load to prevent backfeed and fault propagation. Use Value: 350 mV VF at 100 mA limits insertion loss to <35 mW, preserving bus voltage margin for downstream PD controllers. | Use Scenario: Secondary-side rectification in 3.3 V/1 A synchronous-buck-derived isolated DC/DC modules. IC Role / Device Role: Freewheeling diode replacing MOSFET body diode where gate drive complexity must be minimized. Use Value: 25 pF CT avoids resonance with transformer leakage inductance, enabling stable 2–5 MHz operation without snubbers. |
| Portable Device Battery Charging | Automotive Body Control Module (BCM) Input Clamping |
Use Scenario: OR-ing diode in dual-input (USB + battery) charging circuits for wearables and Bluetooth headsets. IC Role / Device Role: Prevents reverse current flow from battery into disabled USB port while maintaining low dropout. Use Value: 50 µA max IR at 15 V ensures <0.75 µW standby drain-critical for multi-week shelf life in shipped devices. | Use Scenario: Transient voltage suppression on 12 V supply rails feeding microcontroller I/O in BCM subassemblies. IC Role / Device Role: Clamp diode shunting load dump spikes (ISO 7637-2 Pulse 5a) to ground via low-impedance path. Use Value: Guard ring design withstands 5.5 A non-repetitive surge, meeting automotive pulse robustness without external TVS. |
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 SOD-323 package; VF = 370 mV @ 100 mA (higher), IR = 2 µA @ 15 V (lower) | Better leakage performance but higher conduction loss; suited for ultra-low-IQ systems over efficiency-critical ones | Select when standby current dominates thermal budget, e.g., coin-cell IoT sensors |
| NSR0130P2T5G | Smaller SOD-523 package; VF = 320 mV @ 100 mA; IO = 0.3 A (lower) | Lower current rating and smaller footprint; limited to ≤300 mA loads | Choose only for space-constrained sub-300 mA applications where board area is premium |
Compared with SBAT54LT1G and NSR0130P2T5G, BAT760Q-7 uniquely balances 1 A current handling, 350 mV VF, and 50 µA IR in SOD-323-making it optimal for mid-power portable power rails where both efficiency and leakage matter.

FAQ
Is BAT760Q-7 suitable for reverse polarity protection in 5 V USB circuits?
Yes. With 30 V VRRM, 350 mV VF at 100 mA, and cathode-band marking, BAT760Q-7 provides reliable unidirectional blocking in 5 V USB power paths. Its 1 A rating supports full USB 2.0/3.0 bus current, and low leakage (<50 µA) prevents battery drain during standby.
What is the maximum allowable junction temperature for continuous operation?
The BAT760Q-7 has a Tj range of −65 °C to +125 °C. At 1 A IO and 25 °C ambient, junction temperature rises ~426 °C/W × (1 A)2 × Rθ ≈ 100 °C, staying within limit. Derating begins above 25 °C per Fig. 1-maximum ambient is ~75 °C at full 1 A.
Does BAT760Q-7 require special PCB layout for thermal performance?
No special layout is required beyond Diodes' recommended SOD-323 pad dimensions (available in AP02001.pdf). Standard 1.5 mm2 copper pour per terminal suffices for 1 A operation. Avoid thermal isolation-copper connects directly to internal ground or power planes to leverage board-level heat spreading.
Can BAT760Q-7 replace BAT54 series diodes in existing designs?
Yes, with verification. BAT760Q-7 shares SOD-323 footprint and cathode-band polarity with BAT54 variants, but offers higher IO (1 A vs. 0.2–0.3 A) and lower VF (350 mV vs. ~450 mV). Confirm thermal margin and surge requirements-its 5.5 A IFSM exceeds BAT54's 2–3 A rating.
