Product details
Overview
BAT64C-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT23 package, rated for 40 V peak reverse voltage, 250 mA average forward current, and 0.75 V max forward voltage at 100 mA. It features a PN junction guard ring for transient protection and is AEC-Q101 qualified for automotive reliability.
For engineers reviewing the BAT64C-7-F datasheet, BAT64C-7-F pinout, BAT64C-7-F application, or BAT64C-7-F equivalent, key selection criteria include low VF for power-sensitive signal clamping, fast 3.0 ns reverse recovery time for high-frequency switching, and SOT23 footprint compatibility with space-constrained PCB layouts.
Technical Context
This Schottky diode uses a metal–semiconductor junction to achieve low forward voltage drop and rapid carrier recombination, eliminating minority-carrier storage delay. Its guard ring structure enhances ESD and surge immunity without requiring external protection components.
Designed for operation from –65°C to +150°C, it maintains stable VF and IR across temperature, with 6.0 pF capacitance at 1 V reverse bias-enabling use in RF detector and high-speed sampling circuits where parasitic capacitance must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| VRRM | 40 V - maximum repetitive reverse voltage before breakdown; sets safe operating limit in clamp or flyback paths |
| IO | 250 mA - continuous DC forward current rating; defines steady-state power handling in signal routing |
| VF_MAX @ 100mA | 0.75 V - worst-case forward drop at rated load; determines conduction loss in low-voltage bias networks |
| tRR | 3.0 ns - measured with IF = IR = 10 mA, IRR = 0.1IR, RL = 100 Ω; enables >100 MHz switching in RF envelope detection |
| CT @ 1V | 6.0 pF - total junction capacitance at 1 V reverse bias; critical for minimizing signal distortion in high-frequency AC coupling |
| IR_MAX @ 40V | 2.0 µA - maximum leakage at full rated reverse voltage; ensures minimal standby current in battery-backed circuits |
| TJ Range | –65°C to +150°C - operational junction temperature span; supports under-hood automotive and industrial ambient conditions |
Pinout & Package
Package: SOT23 - three-terminal plastic surface-mount package with 0.915 mm nominal lead pitch, 2.40 mm body length, and 1.30 mm body width; optimized for automated pick-and-place and reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Anode (Pin 1) | Forward current entry point | Connected to higher-potential node in clamping or rectification path; polarity marked by cathode band on package top |
| Cathode (Pin 2) | Forward current exit / reverse blocking terminal | Typically tied to ground or reference rail; forms low-impedance discharge path during transient events |
| No-Connect (Pin 3) | Internal die attach pad (non-functional) | Thermally conductive but electrically isolated; improves heat dissipation without circuit connection |
Key Features
| Feature | Design Value |
|---|---|
| Low turn-on voltage | VF ≤ 0.75 V at 100 mA enables <100 mW conduction loss in 3.3 V logic-level protection circuits |
| Fast switching | 3.0 ns tRR supports clean edge detection in 100+ MHz clock recovery and RF demodulation |
| PN junction guard ring | Integrated transient suppression structure eliminates need for discrete TVS in low-energy ESD paths (IEC 61000-4-2 Level 2) |
| AEC-Q101 qualification | Validated for automotive applications including infotainment power sequencing and sensor interface protection |
Applications
| Automotive Sensor Interface Protection | USB Data Line Clamping |
|---|---|
Use Scenario: Protecting LIN bus transceivers from load-dump transients and ESD events in vehicle cabin modules. IC Role / Device Role / Timing Role: Bidirectional clamping diode placed between data line and VCC/GND rails to shunt overvoltage energy. Use Value: 0.75 V VF and 3.0 ns tRR prevent signal distortion during 10–100 ns ESD pulses while maintaining LIN timing integrity. | Use Scenario: Safeguarding USB 2.0 D+/D− lines against ±8 kV contact ESD per IEC 61000-4-2. IC Role / Device Role / Timing Role: Low-capacitance (6.0 pF) Schottky clamp limiting line voltage to <0.8 V above VCC during ESD events. Use Value: Minimal signal degradation preserves 480 Mbps data eye margin; SOT23 footprint fits tight USB connector spacing. |
| RF Signal Detector | Low-Voltage Power OR'ing |

IC Role / Device Role / Timing Role: High-speed rectifier converting RF carrier amplitude into baseband envelope voltage. Use Value: 3.0 ns tRR and 6.0 pF CT enable accurate detection of modulated carriers up to 500 MHz without phase lag. | Use Scenario: Selecting between dual 3.3 V supplies (e.g., main and backup) in portable medical monitors. IC Role / Device Role / Timing Role: Forward-biased Schottky diode providing low-loss power path selection with automatic reverse isolation. Use Value: 0.75 V VF reduces voltage drop vs. MOSFET-based OR'ing, simplifying design while maintaining >95% efficiency at 200 mA. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54CWT1G | Same SOT-23 package, 30 V VRRM, 0.85 V VF @ 100 mA, 2.0 ns tRR | Lower reverse voltage rating limits use in 40 V systems; faster tRR benefits ultra-high-frequency detectors | Select when 30 V rating suffices and sub-3 ns switching is prioritized over voltage headroom |
| NSR0230HT1G | 0.45 V VF @ 100 mA, 40 V VRRM, SOD-123 package (larger footprint), 4 ns tRR | Larger SOD-123 case increases board area; lower VF reduces conduction loss in high-current bias networks | Choose for lowest possible forward loss where PCB space permits larger package |
Compared with SBAT54CWT1G and NSR0230HT1G, BAT64C-7-F uniquely balances 40 V robustness, 0.75 V VF, and 3.0 ns tRR in the compact SOT23 footprint-making it optimal for automotive and USB interfaces where voltage margin, speed, and size are jointly constrained.

FAQ
What is the maximum junction temperature for BAT64C-7-F?
The specified junction and storage temperature range is –65°C to +150°C. This allows reliable operation in under-hood automotive environments and industrial enclosures with elevated ambient temperatures, provided power dissipation remains within derated limits per Figure 4 of the datasheet.
Does BAT64C-7-F have a built-in guard ring, and what does it protect against?
Yes, BAT64C-7-F incorporates a PN junction guard ring structure. This feature enhances transient immunity by distributing electric field stress and preventing premature avalanche breakdown during ESD events and fast-rising voltage spikes, particularly beneficial in unshielded sensor and data line applications.
Is BAT64C-7-F compatible with lead-free reflow soldering processes?
Yes, BAT64C-7-F uses matte tin finish annealed over Alloy 42 leadframe and is fully RoHS compliant. It meets J-STD-020 moisture sensitivity level 1 and is qualified for standard lead-free reflow profiles, including peak temperatures up to 260°C.
How does the 6.0 pF capacitance affect high-frequency performance?
The 6.0 pF total capacitance at 1 V reverse bias minimizes loading on RF signal paths, enabling effective use in 500 MHz envelope detectors and high-speed data line clamps. At higher reverse voltages, capacitance decreases further-supporting broadband impedance matching without added tuning components.
