Product details
Overview
BAT54Q-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT23 package, rated for 30 V peak reverse voltage, 200 mA average forward current, and 0.8 V max forward voltage at 100 mA. It features a PN junction guard ring for transient/ESD protection and is AEC-Q101 qualified for automotive use.
For engineers reviewing the BAT54Q-7-F datasheet, BAT54Q-7-F pinout, BAT54Q-7-F application, or BAT54Q-7-F equivalent, key selection criteria include low VF (≤800 mV @ 100 mA), fast tRR (≤5 ns), low IR (≤2 µA @ 25 V), SOT23 footprint compatibility, and AEC-Q101 qualification for under-hood signal clamping and polarity protection.
Technical Context
This Schottky diode uses a metal-semiconductor junction to achieve low forward voltage drop and nanosecond-scale reverse recovery. Its guard ring structure enhances ruggedness against ESD and voltage transients without compromising switching speed.
Designed for high-reliability automotive environments, it operates across –55°C to +150°C with thermal resistance RθJA = 500°C/W on FR-4 and meets RoHS 3, halogen-free, and antimony-free "Green" requirements per Diodes Incorporated's definitions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum DC blocking voltage before breakdown; sets upper limit for reverse-biased clamping applications. |
| IO | 200 mA - Continuous forward current rating; defines steady-state power handling in rectification or steering paths. |
| VF Max | 0.8 V @ 100 mA - Low conduction loss enables efficient low-voltage signal routing and reduces self-heating. |
| IR Max | 2.0 µA @ 25 V - Minimal leakage preserves signal integrity in high-impedance bias or sensing nodes. |
| tRR | 5.0 ns - Fast recovery supports high-frequency switching (>100 MHz) in RF detector or sample-and-hold circuits. |
| CT | 10 pF @ 1 V - Low junction capacitance minimizes signal distortion in high-speed data line protection. |
Pinout & Package
Package: SOT23 - 3-pin surface-mount plastic package (2.9 mm × 1.3 mm × 1.0 mm), moisture sensitivity level 1, lead-free matte tin plating over Alloy 42 leadframe.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in clamping, OR-ing, or reverse polarity protection circuits. |
| Cathode (Pin 2) | Forward current exit / reverse voltage reference | Typically tied to ground or lower-potential rail; forms cathode-common configuration in dual-diode variants. |
| No Connection (Pin 3) | Unused terminal | Internally unconnected; electrically isolated-no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Low turn-on voltage | VF ≤ 400 mV @ 10 mA enables operation in sub-1 V logic interfaces and battery-powered sensor nodes. |
| Fast switching | tRR ≤ 5 ns supports >100 MHz signal detection and prevents pulse distortion in high-speed data lines. |
| PN junction guard ring | Provides robust ESD immunity (IEC 61000-4-2 Level 4) and surge tolerance without external TVS components. |
| AEC-Q101 qualification | Validated for automotive-grade reliability including temperature cycling, HTRB, and ESD testing per JESD47. |
Applications
| Automotive Body Control Module (BCM) | USB Port Polarity Protection |
|---|---|
Use Scenario: Reverse battery connection protection in 12 V BCM power inputs. IC Role / Device Role / Timing Role: Series-connected Schottky diode providing low-loss forward path while blocking reverse current. Use Value: Prevents damage to microcontrollers and CAN transceivers during service errors; 0.8 V drop limits power loss to <160 mW at 200 mA. | Use Scenario: Preventing damage from miswired USB Type-A cables in embedded host ports. IC Role / Device Role / Timing Role: Cathode-tied-to-VBUS, anode-to-load configuration for input polarity enforcement. Use Value: Enables plug-and-play safety without sacrificing signal integrity-10 pF capacitance avoids USB 2.0 eye diagram degradation. |
| Industrial Sensor Signal Clamping | RF Detector Diode in 2.4 GHz ISM Band |
Use Scenario: Protecting ADC inputs of analog front-ends from ESD-induced overvoltage spikes. IC Role / Device Role / Timing Role: Bidirectional clamping diode pair (with BAT54CQ) referenced to VDD and GND. Use Value: Guard ring ensures clamping action survives ≥8 kV contact discharge per IEC 61000-4-2 without parameter shift. | Use Scenario: Envelope detection in low-power BLE receiver front-ends. IC Role / Device Role / Timing Role: Zero-bias RF detector operating in square-law region below 100 µA. Use Value: 5 ns tRR and 10 pF CT support accurate demodulation up to 2.4835 GHz with minimal phase error. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Same VRRM/IO, but VF = 0.95 V max @ 100 mA; SOD-123 package (larger footprint). | Lacks AEC-Q101 qualification; not approved for automotive production. | Select only for cost-sensitive industrial PCBs where space allows larger package and automotive compliance is unnecessary. |
| BAT54WS-7-F | Identical electrical specs and AEC-Q101 rating; SOD-323 package (0.8 mm × 1.2 mm) vs. SOT23 (1.3 mm × 2.9 mm). | Smaller footprint enables tighter layout in space-constrained USB-C or miniaturized modules. | Prefer when board area is constrained and same performance/reliability must be retained. |
Compared with SBAT54LT1G and BAT54WS-7-F, BAT54Q-7-F uniquely balances SOT23 manufacturability, AEC-Q101 compliance, and 0.8 V VF-making it optimal for automotive infotainment power rails and industrial fieldbus interface protection where standardization and supply continuity matter.

FAQ
What is the maximum junction temperature for BAT54Q-7-F?
The absolute maximum junction temperature is +150°C, with continuous operation supported from –55°C to +150°C ambient. Derating begins above +25°C per the power derating curve: PD drops linearly to zero at +150°C, with RθJA = 500°C/W on standard FR-4 board.
Is BAT54Q-7-F suitable for bidirectional ESD protection?
No-it is a single-anode, single-cathode Schottky diode optimized for unidirectional conduction. For bidirectional ESD clamping, Diodes recommends using BAT54CQ (dual common-cathode) or BAT54SQ (dual series) in appropriate configurations with external resistors or TVS devices.
Does BAT54Q-7-F have a specified ESD rating?
While not individually rated per IEC 61000-4-2 in the datasheet, its integrated PN junction guard ring provides inherent robustness-validated via AEC-Q101 stress tests including human-body model (HBM) ≥2 kV and machine model (MM) ≥200 V, enabling reliable use in automotive ESD-prone zones.
Can BAT54Q-7-F replace BAT54-7-F in existing designs?
Yes-BAT54Q-7-F is the AEC-Q101 qualified version of BAT54-7-F, sharing identical electrical specs, pinout, and SOT23 package. The Q-suffix denotes automotive qualification, PPAP capability, and IATF 16949 manufacturing-no layout or schematic changes are needed for upgrade.
