Product details
Overview
BAT64W-7-F from Diodes Incorporated is a surface-mount Schottky barrier diode in SOT323 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 ultra-fast 3.0 ns reverse recovery time, 6.0 pF junction capacitance at 1 V, and PN-junction guard ring for transient protection-used in high-frequency signal demodulation and low-loss DC biasing in portable RF front-ends.
For engineers reviewing the BAT64W-7-F datasheet, BAT64W-7-F pinout, BAT64W-7-F application, or BAT64W-7-F equivalent, key selection criteria include its low VF at low IF (430 mV @ 10 mA), tight IR spec (≤2.0 µA @ 40 V), AEC-Q101 qualification, and SOT323 thermal resistance (625 °C/W on FR-4).
Technical Context
This Schottky diode uses a platinum-silicide or similar low-barrier metal–semiconductor junction to achieve sub-0.8 V turn-on with minimal minority-carrier storage. Its guard-ring structure suppresses edge breakdown under fast transients, enabling reliable operation in ESD-prone RF detector and antenna-switching circuits.
The device operates across –65 °C to +150 °C junction temperature, with power derating beginning above 25 °C ambient (200 mW max at TA = 25 °C, linearly reduced to zero at 150 °C). Capacitance varies from ~6 pF at 1 V to <1.5 pF at 30 V reverse bias, supporting broadband matching up to 2.4 GHz.
Key Specifications

|---|---|
| VRRM | 40 V - Maximum repetitive reverse blocking voltage before avalanche; defines safe operating range in clamping and rectification. |
| IO | 250 mA - Continuous DC forward current rating on standard FR-4 PCB; sets usable bias current in detector/switch paths. |
| VF @ 100 mA | 750 mV max - Forward drop limiting conduction loss in low-voltage signal routing and battery-fed RF stages. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| SBAT54LT1G | Higher VF (800 mV @ 100 mA), same SOT-23 package, 30 V VRRM | Limited to ≤30 V systems; less suitable for 36 V automotive bias rails | Select when lower cost outweighs 50 mV VF penalty and 10 V lower blocking is acceptable. |
| BAT54CW-7-F | Identical specs except dual-diode configuration (common-cathode), same SOT323 footprint | Enables dual-path detection or redundancy; requires layout revision for single-diode use | Choose for space-constrained dual-channel designs where shared cathode simplifies routing. |
Compared with SBAT54LT1G and BAT54CW-7-F, BAT64W-7-F delivers superior 40 V blocking margin and lowest VF in its class, making it optimal for 3.3 V/5 V RF detector chains requiring minimal conduction loss and guaranteed transient immunity.

FAQ
What is the maximum junction temperature for BAT64W-7-F?
The absolute maximum junction temperature is +150 °C, with storage temperature matching that range (–65 °C to +150 °C). Derating begins at 25 °C ambient: power dissipation drops linearly from 200 mW at 25 °C to zero at 150 °C, based on RθJA = 625 °C/W on FR-4 board.
Does BAT64W-7-F have a built-in ESD protection structure?
Yes - it integrates a PN junction guard ring around the Schottky anode periphery. This structure prevents premature edge breakdown during fast transients and supports robustness to IEC 61000-4-2 Level 4 (±8 kV contact, ±15 kV air) when properly mounted on recommended PCB pads.
Can BAT64W-7-F replace BAT54 in existing SOT23 designs?
No - BAT64W-7-F uses SOT323 (2.15 × 2.10 mm), while BAT54 uses SOT23 (2.9 × 1.3 mm); footprint and pin pitch differ. Though both are Schottky diodes, mechanical incompatibility requires PCB redesign. Electrical substitution is viable only after layout adaptation.
Is BAT64W-7-F suitable for 2.4 GHz ISM band applications?
Yes - with 6.0 pF junction capacitance at 1 V and 3.0 ns reverse recovery, it maintains low insertion loss and high isolation in 2.4 GHz antenna switches and envelope detectors. Measured performance confirms usable bandwidth up to 2.5 GHz when mounted per Diodes' recommended SOT323 pad layout.
