Product details
Overview
BAT1000Q-7-F from Diodes Incorporated is a 1A surface-mount Schottky barrier rectifier in SOT23 package, rated for 40V peak repetitive reverse voltage and featuring a typical forward voltage of 225mV at 50mA. It delivers low conduction loss and fast 12ns reverse recovery time, and is AEC-Q101 qualified for automotive power conversion circuits including DC-DC converters and mobile telecommunications front-end supplies.
For engineers reviewing the BAT1000Q-7-F datasheet, BAT1000Q-7-F pinout, BAT1000Q-7-F application, or BAT1000Q-7-F equivalent, key selection criteria include its 1A average rectified current rating, 225–600mV forward voltage range across 50–1500mA, 175pF junction capacitance at 0V, AEC-Q101 qualification status, and SOT23 thermal resistance of 200°C/W.
Technical Context
The BAT1000Q-7-F employs a planar Schottky barrier structure optimized for low VF and high conductance, enabling efficient operation in high-frequency switching applications. Its 12ns reverse recovery time supports >1MHz DC-DC converter topologies without significant switching loss penalties.
Designed for automotive-grade reliability, it operates from –40°C to +125°C junction temperature and meets IATF 16949 manufacturing requirements. The device's 40V VRRM and 1A IO rating target 12V/24V system rail rectification and OR-ing functions where low forward drop minimizes power loss and thermal stress.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky rectifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SB140-TB-E3/52 | 40V VRRM, 1A IO, but VF = 450mV min @ 1A - 2× higher conduction loss | Not AEC-Q101 qualified; limited to commercial-grade consumer power supplies | Select only if automotive qualification is not required and cost is primary constraint |
| RB050M-30 | 30V VRRM, 1A IO, VF = 320mV typ @ 1A - lower voltage rating, higher VF | Optimized for 5V/12V logic rails; unsuitable for 24V automotive systems | Choose when system reverse voltage stays below 30V and thermal margin allows higher VF |
Compared with SB140-TB-E3/52 and RB050M-30, the BAT1000Q-7-F uniquely combines AEC-Q101 qualification, 40V blocking, and sub-300mV VF at low currents-making it the only option validated for automotive 12V/24V DC-DC rectification with thermal and reliability constraints.

FAQ
What is the maximum junction temperature for continuous operation?
The BAT1000Q-7-F is rated for continuous operation from –40°C to +125°C junction temperature. This range is validated per AEC-Q101 stress testing and applies under specified thermal conditions using Diodes' recommended SOT23 PCB pad layout with 200°C/W RθJA.
Is BAT1000Q-7-F pin-compatible with BAT54 series diodes?
No. While both use SOT23 packaging, BAT1000Q-7-F has anode-cathode-NC pinout (Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = NC), whereas BAT54 variants use anode-cathode-anode or cathode-anode-cathode configurations. Physical mounting is identical, but circuit substitution requires schematic and layout revision.
Does this part support reflow soldering per JEDEC J-STD-020?
Yes. The BAT1000Q-7-F is rated for moisture sensitivity level 1 per J-STD-020 and supports standard Pb-free reflow profiles up to 260°C peak temperature. Its matte tin finish and Alloy 42 leadframe ensure reliable wetting and intermetallic formation without voiding or delamination.
How does the 12ns reverse recovery time impact EMI in switching converters?
The 12ns tRR minimizes reverse recovery current spikes and associated high-frequency ringing, reducing conducted EMI in buck/boost converters operating above 500kHz. Measured data shows >10dB lower 30–100MHz noise amplitude versus standard 100ns silicon diodes under identical 1A/100kHz test conditions.
