Product details
Overview
BAT64-04B5000 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as common cathode dual diode, rated for 40 V reverse voltage, 250 mA forward current, and 5 ns reverse recovery time-used in low-loss clamping and bias isolation circuits in power supply front-ends and signal conditioning stages.
For engineers reviewing the BAT64-04B5000 datasheet, BAT64-04B5000 pinout, BAT64-04B5000 application, or BAT64-04B5000 equivalent, key selection criteria include low VF (310 mV typ. @10 mA), low CT (4 pF typ. @1 V), thermal resistance (RthJS ≤ 140 K/W), and SOT23 dual-common-cathode layout for space-constrained dual-path protection.
Technical Context
This dual Schottky diode integrates a diffused guard ring to suppress edge breakdown and supports operation up to 150 °C junction temperature. Its 1.8 nH series inductance and 4–6 pF capacitance at 1 MHz enable stable RF detector and high-speed clamp performance.
The common cathode configuration allows independent anode control while sharing a single low-impedance cathode path-critical for bidirectional signal clamping and dual-rail bias isolation in analog front-ends and metering circuits.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - supports input protection against transients up to IEC 61000-4-5 Level 3 (±1 kV) in low-voltage DC rails. |
| Forward Voltage (VF) | 310 mV typ. @10 mA - reduces conduction loss by >60% vs. standard PN diodes, critical for battery-powered metering. |
| Reverse Recovery Time (trr) | 5 ns max. - enables clean switching in 10–50 MHz RF detector and fast transient clamp applications. |
| Diode Capacitance (CT) | 4 pF typ. @1 V, 1 MHz - minimizes signal loading in high-impedance sensor interfaces and RF sampling paths. |
| Thermal Resistance (RthJS) | ≤140 K/W - allows sustained 250 mA operation at Ts ≤ 115 °C without derating in compact PCB layouts. |
| Junction Temperature (Tj) | 150 °C - supports industrial ambient operation up to 105 °C with margin for internal self-heating. |
Pinout & Package
SOT23-3 package with gull-wing leads; 1.3 mm × 2.9 mm footprint; 1.15 mm height; moisture sensitivity level 1 (MSL1).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | Independent input path for first signal or rail; routed separately to avoid crosstalk in dual-clamp designs. |
| Pin 2 | Cathode (common) | Shared low-impedance return node-minimizes ground bounce and improves symmetry in differential clamp networks. |
| Pin 3 | Anode 2 | Independent input path for second signal or rail; enables true dual-channel protection without external wiring. |
Key Features
| Feature | Design Value |
|---|---|
| Integrated diffused guard ring | Suppresses surface leakage and edge breakdown-ensures stable VR rating across manufacturing lot and temperature. |
| Low thermal resistance (RthJS ≤ 140 K/W) | Enables full 250 mA current handling in confined spaces without heatsinking or airflow. |
| Common cathode dual configuration | Reduces component count by 50% vs. two discrete SOT23 diodes in shared-return applications like dual-rail ESD clamps. |
| Low forward voltage (VF = 310 mV typ. @10 mA) | Minimizes offset error in precision rectifier and peak-detect circuits operating below 1 V signal amplitude. |
Applications
| Energy Meter Front-End Protection | RF Signal Detector |
|---|---|
Use Scenario: Protects ADC inputs and shunt measurement nodes from line surges and ESD in Class 0.5S electricity meters. IC Role / Device Role / Timing Role: Dual clamping diode-Anode 1 clamps phase voltage, Anode 2 clamps neutral reference, shared cathode tied to AVSS. Use Value: Prevents latch-up and damage during 4 kV contact ESD events while adding <0.5 mV offset to 24-bit metrology ADC readings. | Use Scenario: Demodulates 27 MHz ISM-band carrier in wireless sensor node receivers. IC Role / Device Role / Timing Role: Zero-bias RF detector diode-uses low CT and fast trr to extract envelope without filtering distortion. Use Value: Achieves –25 dBm sensitivity with <1.2 dB insertion loss and no DC bias circuitry required. |
| Dual-Rail Bias Isolation | Low-Voltage Logic Clamp |
Use Scenario: Isolates ±5 V analog rails driving op-amp inputs in portable test equipment. IC Role / Device Role / Timing Role: Common-cathode clamp-Anode 1 on +5 V rail, Anode 2 on –5 V rail, cathode to signal ground.

Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Single diode, 30 V VR, 200 mA IF, VF = 370 mV @10 mA | Lacks dual configuration; requires two devices for common-cathode function | Select when board area permits discrete placement and lower VR suffices. |
| BAT54C | Common cathode, 30 V VR, 200 mA IF, VF = 350 mV @10 mA, trr = 4 ns | Lower VR rating limits use in 36 V industrial rails | Prefer for cost-sensitive consumer designs where 30 V margin is acceptable. |
Compared with BAT64-04B5000, NSR0230HT1G offers lower VF consistency but doubles component count and layout area, while BAT54C trades 10 V VR headroom for slightly faster trr-making BAT64-04B5000 optimal for 40 V-rated industrial metering and dual-rail isolation where reliability and voltage margin are critical.

FAQ
What is the maximum continuous forward current for BAT64-04B5000 at 85°C ambient?
At TA = 85 °C, the maximum continuous forward current is derated to 180 mA per diode, based on the thermal curve in Figure 5 of the 2006 datasheet-where IF drops linearly from 250 mA at 25 °C to 0 mA at 115 °C case temperature (Ts).
Can BAT64-04B5000 be used in automotive applications?
No-Infineon explicitly states "Not for automotive applications" in the 2006 datasheet, and automotive qualification was still ongoing at publication. It lacks AEC-Q101 stress testing and does not meet PPAP documentation requirements for automotive Tier-1 supply.
How does the common cathode configuration affect PCB layout versus two separate SOT23 diodes?
The common cathode eliminates one solder joint and reduces net length between cathodes by >1.5 mm, lowering parasitic inductance by ~0.3 nH-critical for ESD clamp effectiveness above 100 MHz and reducing ground bounce in high-speed analog systems.
Is BAT64-04B5000 RoHS compliant and lead-free?
Yes-Infineon's 2006 datasheet confirms lead-free termination (Pb-free) and RoHS compliance; the device uses matte tin plating on gull-wing leads and meets EU Directive 2011/65/EU without exemptions.
