Product details

Overview

BAT1000-7-F from Diodes Incorporated is a 1A surface-mount Schottky barrier rectifier in SOT23 package, featuring 40V peak repetitive reverse voltage, 225–600mV forward voltage (depending on current), and 12ns reverse recovery time. It delivers high conductance with low forward voltage drop for efficient power conversion in space-constrained DC-DC converters and mobile telecom circuits.

For engineers reviewing the BAT1000-7-F datasheet, BAT1000-7-F pinout, BAT1000-7-F application, or BAT1000-7-F equivalent, key selection criteria include its 1A average rectified current rating, 200°C/W thermal resistance, 175pF junction capacitance at 0V, AEC-Q101 qualification status (BAT1000Q variant), and SOT23-compatible footprint for high-density PCB layouts.

Technical Context

The BAT1000-7-F employs a planar Schottky barrier structure optimized for low VF and fast switching, enabling minimal conduction loss in high-frequency rectification. Its 12ns reverse recovery time supports operation up to several MHz in synchronous rectifier and flyback auxiliary winding applications.

Thermally, it is rated for -40°C to +125°C operating junction temperature and dissipates up to 500mW on FR-4 board with recommended pad layout. The device uses matte tin-plated Alloy 42 leadframe and meets RoHS 3, halogen-free, and antimony-free "Green" requirements.

Key Specifications

Parameter	Value and Actual Design Meaning
V_RRM	40 V - Maximum non-repetitive reverse voltage before breakdown; sets upper limit for blocking capability in 3.3V/5V/12V rail clamping or output rectification.
I_O	1.0 A - Average rectified current under specified thermal conditions; defines continuous DC output capability in compact DC-DC modules.
V_F @ 1A	420–500 mV - Forward voltage at full rated current; enables <0.5W conduction loss at 1A, critical for thermal management in sealed enclosures.
t_RR	12 ns - Reverse recovery time; permits use in >1MHz switching topologies without significant switching loss penalty.
C_T @ 0V	175 pF - Junction capacitance at zero bias; impacts high-frequency noise coupling and EMI filter design in RF-sensitive power stages.
R_θJA	200 °C/W - Thermal resistance junction-to-ambient on standard FR-4; determines required copper area and airflow for safe 1A operation at 125°C ambient.

Pinout & Package

Applications

DC-DC Converter Output Rectification

PCMCIA Card Power Management

Use Scenario: Secondary-side rectification in 3.3V/5V buck converters powering FPGA I/O banks or microcontroller cores.

IC Role / Device Role / Timing Role: Unidirectional current steering element converting switched AC-like waveform into regulated DC output.

Use Value: 225–420mV V_F minimizes voltage drop and heat generation, preserving regulation margin and enabling smaller heatsinking.

Use Scenario: Hot-swap protection and reverse-polarity blocking in PCMCIA Type II card slots.

IC Role / Device Role / Timing Role: Polarity guard and transient clamp during insertion/removal events.

Use Value: 40V V_RRM withstands ±15V transients; 12ns t_RR prevents latch-up during rapid voltage reversal.

Mobile Telecom RF Module Biasing

USB-C Power Path Protection

Use Scenario: Isolation of bias rails feeding GaAs RF power amplifiers in LTE/5G front-end modules.

IC Role / Device Role / Timing Role: Low-loss DC feed-through with minimal parasitic capacitance to preserve RF impedance matching.

Use Value: 175pF C_T at 0V avoids detuning of 2.4GHz/5GHz matching networks; SOT23 footprint fits tight RF layout constraints.

Use Scenario: Reverse-current blocking in USB-C PD sink paths where VBUS may exceed source voltage during negotiation.

IC Role / Device Role / Timing Role: Unidirectional power path gate preventing backfeed from battery or downstream devices.

Use Value: 1A I_O rating supports 3A USB-C designs with derating margin; 200°C/W R_θJA allows thermal-aware layout in thin-profile portable devices.

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 V_RRM, 1A I_O, but VF = 450–550mV @ 1A; TO-236AB (SMA) package, larger footprint	Higher VF increases conduction loss; SMA package requires more board area and has higher R_θJA (~250°C/W)	Select when legacy SMA footprint compatibility is required and thermal headroom exists.
SS12-E3/57T	20V V_RRM, 1A I_O, VF = 350–450mV @ 1A; same SOT23 package	Lower V_RRM restricts use to ≤15V systems; unsuitable for 24V auxiliary rails or 36V telecom inputs	Select only for low-voltage (<15V) applications where reduced reverse voltage rating is acceptable.

Compared with SB140-TB-E3/52 and SS12-E3/57T, the BAT1000-7-F offers the lowest VF across its full 1A range and best thermal performance in SOT23, making it optimal for high-efficiency, space-constrained 5–24V power rails where both voltage headroom and thermal density matter.

FAQ

What is the maximum junction temperature for BAT1000-7-F?

The BAT1000-7-F is rated for an operating junction temperature range of -40°C to +125°C. This allows reliable operation in automotive cabin environments and thermally dense portable electronics, provided the 200°C/W thermal resistance is managed via appropriate PCB copper area and ambient airflow per the recommended pad layout.

Is BAT1000-7-F suitable for automotive applications?

The BAT1000-7-F itself is not AEC-Q101 qualified; however, the pin- and form-compatible BAT1000Q-7-F variant is fully AEC-Q101 qualified, PPAP capable, and manufactured in IATF 16949 certified facilities. For automotive-grade designs, BAT1000Q-7-F must be specified and sourced separately.

How does the SOT23 package affect thermal performance?

The SOT23 package limits thermal dissipation to 500mW under standard FR-4 mounting conditions due to its small size and 200°C/W R_θJA. To sustain 1A continuous current, designers must use minimum 10mm² copper pour on the cathode pad and avoid enclosing the device in sealed housings without forced airflow.

What is the significance of the "7-F" suffix in BAT1000-7-F?

The "-7-F" suffix denotes tape-and-reel packaging: "7" indicates 3000 units per reel, and "F" signifies lead-free, RoHS-compliant plating. This packaging format is optimized for automated SMT placement and ensures consistent handling in high-volume manufacturing environments.
