Product details
Overview
BAT54AQ-7-F from Diodes Incorporated is a 30 V, 200 mA surface-mount Schottky barrier diode in SOT23 package, featuring 800 mV max forward voltage at 100 mA, 2 µA max reverse leakage at 25 V, and 5 ns reverse recovery time-designed for low-loss clamping and high-speed switching in automotive power rail protection circuits.
For engineers reviewing the BAT54AQ-7-F datasheet, BAT54AQ-7-F pinout, BAT54AQ-7-F application, or BAT54AQ-7-F equivalent, key selection criteria include its AEC-Q101 qualification, PN junction guard ring for ESD/transient robustness, SOT23 thermal resistance (RθJA = 500 °C/W), and green RoHS-compliant lead-free plating on Alloy 42 leadframe.
Technical Context
This Schottky diode uses a metal–semiconductor junction to achieve low forward voltage drop and fast switching, with no minority-carrier storage delay. Its integrated PN junction guard ring provides defined breakdown behavior and enhanced ESD immunity up to ±8 kV HBM.
Rated for -55 °C to +150 °C operation, it supports automotive-grade reliability under thermal cycling and humidity bias stress. The device's 10 pF capacitance at 1 V reverse bias enables use in RF detector and high-frequency clamp applications without signal distortion.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 30 V - Maximum repetitive reverse blocking voltage before avalanche conduction begins |
| IO | 200 mA - Continuous DC forward current rating under FR-4 board conditions |
| VF Max | 800 mV @ 100 mA - Ensures minimal conduction loss in low-voltage power path clamping |
| IR Max | 2 µA @ 25 V - Low leakage preserves battery life in always-on automotive subsystems |
| tRR | 5 ns - Enables clean switching in 10–50 MHz signal routing and snubbing |
| CT | 10 pF @ 1 V, 1 MHz - Limits capacitive loading in high-speed data line protection |
| RθJA | 500 °C/W - Requires careful PCB copper pour design for sustained 200 mW dissipation |
Pinout & Package
Package: SOT23 - 3-terminal surface-mount plastic package with matte tin finish over Alloy 42 leadframe; moisture sensitivity level 1 per J-STD-020; weight ≈ 0.008 g.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in clamping or OR-ing configuration |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Typically tied to ground or lower-rail reference for unidirectional protection |
| No Connection (Pin 3) | Internal die attach pad (non-functional) | Thermally conductive but electrically isolated; may be grounded for thermal relief |
Key Features
| Feature | Design Value |
|---|---|
| Low turn-on voltage | VF ≤ 400 mV @ 10 mA - Reduces forward drop in 3.3 V/5 V rail clamping paths |
| Fast switching | tRR ≤ 5 ns - Eliminates tail current in PWM-driven load disconnect circuits |

Applications
| Automotive Power Rail Protection | USB Data Line Clamping |
|---|---|
Use Scenario: Reverse polarity and load dump surge suppression on 12 V battery-fed ECUs. IC Role / Device Role / Timing Role: Unidirectional shunt clamp placed between battery input and LDO input. Use Value: 30 V VRRM withstands ISO 7637-2 Pulse 5a (up to 35 V), while 5 ns tRR prevents latch-up during transient edge transitions. | Use Scenario: ESD protection for USB 2.0 D+/D− lines in infotainment head units. IC Role / Device Role / Timing Role: Low-capacitance bidirectional clamp (anode-cathode pair) referenced to VBUS and GND. Use Value: 10 pF CT avoids signal integrity degradation at 480 Mbps; guard ring ensures ±8 kV HBM immunity per IEC 61000-4-2. |
| Low-Voltage OR-ing Diode | RF Detector Input Stage |
Use Scenario: Power path selection between primary and backup Li-ion cells in telematics modules. IC Role / Device Role / Timing Role: Forward-biased Schottky in series with each cell output to prevent backfeed. Use Value: 800 mV VF at 100 mA limits voltage drop to <3% in 3.7 V systems, improving battery runtime efficiency. | Use Scenario: Envelope detection of 900 MHz ISM band signals in TPMS receiver front-ends. IC Role / Device Role / Timing Role: Zero-bias RF rectifier converting AC envelope to DC baseband voltage. Use Value: Low junction capacitance and absence of minority-carrier delay enable accurate amplitude tracking below 10 ns rise time. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54DWQ-7-F | Dual common-cathode configuration in SOT363; VF = 800 mV @ 100 mA per diode | Requires dual-rail clamping or matched-path OR-ing; occupies larger footprint | Select when two independent Schottky paths are needed in same thermal zone |
| NSR0230P2T5G | Lower VF (360 mV @ 10 mA); 200 mA IO; SOD-523 package; not AEC-Q101 qualified | Limited to consumer-grade portable devices; lacks automotive qualification and guard ring | Choose only for cost-sensitive non-automotive designs where ESD immunity is externally managed |
Compared with SBAT54DWQ-7-F and NSR0230P2T5G, BAT54AQ-7-F uniquely combines AEC-Q101 qualification, integrated guard ring, and single-diode SOT23 compactness-making it the only option qualified for direct integration into IATF 16949 production lines without additional system-level ESD hardening.

FAQ
What is the maximum allowable junction temperature for BAT54AQ-7-F?
The absolute maximum junction temperature is +150 °C, with continuous operation limited by thermal derating: power dissipation must be reduced linearly above +25 °C ambient at 0.4 mW/°C (based on RθJA = 500 °C/W). At +100 °C ambient, maximum safe PD drops to 100 mW.
Is BAT54AQ-7-F suitable for bidirectional ESD protection?
No-it is a unidirectional Schottky diode. For bidirectional protection, two BAT54AQ-7-F devices must be used in series opposition (anode-to-anode or cathode-to-cathode), or a dedicated TVS array like D28V0L4B2P should be selected instead.
Does BAT54AQ-7-F have a specified reverse recovery charge (Qrr)?
No Qrr value is specified in the datasheet. As a majority-carrier Schottky device, it exhibits negligible stored charge; reverse recovery is governed solely by junction capacitance discharge, resulting in the measured 5 ns tRR with no tail current.
Can BAT54AQ-7-F replace BAT54 in existing designs?
Yes-BAT54AQ-7-F is the AEC-Q101 qualified, green-compliant version of BAT54 with identical electrical specs and SOT23 pinout. It adds automotive qualification, guard ring ESD protection, and halogen-free packaging, making it a direct upgrade for automotive and industrial applications.
