Product details
Overview
BAT64-06B5003 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as common anode 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 portable instrumentation and signal conditioning front-ends.
For engineers reviewing the BAT64-06B5003 datasheet, BAT64-06B5003 pinout, BAT64-06B5003 application, or BAT64-06B5003 equivalent, key selection criteria include low VF (370 mV typ. at 30 mA), low CT (4 pF typ. at 1 V), thermal resistance (≤140 K/W), and SOT23-compatible layout for space-constrained analog interfaces.
Technical Context
This dual common-anode Schottky diode integrates a diffused guard ring to suppress edge breakdown and supports fast switching with sub-5 ns trr under IF = 10 mA / IR = 1 mA conditions. Its low thermal resistance (≤140 K/W) enables sustained 250 mA operation up to Ts = 115°C without derating beyond datasheet limits.
The device exhibits VF = 310–430 mV across 10–30 mA DC forward current and CT = 4–6 pF at 1 MHz/1 V, making it suitable for RF detector and high-frequency clamp applications where junction capacitance and forward conduction loss must be tightly controlled.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 40 V - sets maximum allowable blocking voltage in clamp or protection circuits |
| Forward Current (IF) | 250 mA - continuous DC current handling capability at TA = 25°C |
| Reverse Recovery Time (trr) | 5 ns max - enables use in >100 MHz signal routing and RF envelope detection |
| Diode Capacitance (CT) | 4 pF typ. at 1 V, 1 MHz - minimizes signal loading in high-Z analog nodes |
| Forward Voltage (VF) | 370 mV typ. at 30 mA - reduces power loss and self-heating in battery-powered bias networks |
| Thermal Resistance (RthJS) | ≤140 K/W - allows direct PCB copper pour thermal coupling for stable operation at Ts ≤ 115°C |
Pinout & Package
SOT23-3 package with gull-wing leads; 1.3 mm × 2.9 mm footprint; 1.15 mm height; standard marking "66s" on top surface.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode 1 | First Schottky junction anode; connects to input node requiring clamping or isolation |
| Pin 2 | Cathode (common) | Shared cathode node for both diodes; ties to reference or ground plane |
| Pin 3 | Anode 2 | Second Schottky junction anode; enables dual-path protection or differential clamping |
Key Features
| Feature | Design Value |
|---|---|
| Integrated diffused guard ring | Suppresses premature edge breakdown, ensuring stable VR rating across temperature and process variation |
| Low forward voltage (VF) | 310–430 mV range at 10–30 mA enables efficient biasing in low-voltage analog rails |
| Low junction capacitance | 4–6 pF at 1 V supports RF detector linearity up to 2 GHz without added tuning |
| High surge tolerance | 800 mA non-repetitive peak current withstands ESD-induced transients in meter input stages |
Applications
| Meter Input Protection | RF Signal Detector |
|---|---|
Use Scenario: Clamp overvoltage spikes on DMM input terminals during accidental connection to live circuits. IC Role / Device Role / Timing Role: Dual-anode Schottky clamp limiting input swing to ±0.4 V relative to reference rail. Use Value: Prevents op-amp input stage damage while maintaining <100 ps response due to 5 ns trr and low CT. | Use Scenario: Demodulate AM signals in handheld spectrum analyzers and RF field strength meters. IC Role / Device Role / Timing Role: Zero-bias envelope detector leveraging low VF and minimal stored charge. Use Value: Delivers >45 dB dynamic range at 900 MHz with no external bias network required. |
| Dual-Rail Bias Isolation | Low-Voltage Logic Clamping |
Use Scenario: Isolate bias voltages between ADC driver and sensor amplifier in multi-supply data acquisition systems. IC Role / Device Role / Timing Role: Common-cathode dual diode blocking reverse leakage between ±2.5 V rails. Use Value: Limits inter-rail leakage to <2 µA at 85°C, preserving PSRR above 80 dB. | Use Scenario: Clamp I/O pins of 1.8 V microcontrollers against 3.3 V bus transients in mixed-voltage interfaces. IC Role / Device Role / Timing Role: Fast-turn-on Schottky path shunting overshoot to VDDIO or GND. Use Value: Responds within 5 ns to limit excursion to <2.2 V, avoiding latch-up in core logic. |
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 @ 100 mA | Lacks dual configuration; requires two devices for common-cathode function | Select when board area permits discrete placement and only one clamp path is needed |
| BAT54C | Common-cathode dual, 30 V VR, 200 mA IF, VF = 380 mV @ 10 mA | Lower VR rating and higher VF reduce margin in 3.3 V+ clamping and high-temp operation | Acceptable for cost-sensitive 3.3 V systems where 40 V VR headroom is not required |
Compared with NSR0230HT1G and BAT54C, BAT64-06B5003 delivers higher reverse voltage margin, lower thermal resistance, and tighter VF consistency across 1–100 mA-critical for precision metering and RF detector stability across temperature.

FAQ
What is the maximum operating temperature for BAT64-06B5003?
The junction temperature limit is 150°C, and the maximum soldering-point temperature is 115°C per datasheet. Derating begins above this point; continuous operation at 250 mA requires adequate PCB copper area to maintain RthJS ≤140 K/W and keep Ts ≤115°C.
Is BAT64-06B5003 suitable for automotive applications?
No-this variant is explicitly marked "Not for automotive applications" in the datasheet. While automotive qualification was ongoing in 2006, no AEC-Q101 qualified version of BAT64-06B5003 exists; use BAT64-06W or BAT64-06E6327 for qualified alternatives.
How does the common-anode configuration affect circuit layout?
The common-anode arrangement places both anodes on Pins 1 and 3, with the shared cathode on Pin 2. This supports dual-input clamping to a single reference rail or bidirectional transient suppression without adding external nodes-reducing parasitic inductance versus discrete diode pairs.
What is the significance of the "66s" top-side marking?
"66s" is the standardized Infineon marking code for BAT64-06 in B5003 packaging. It identifies the device type, configuration (common anode), and reel format (3k per 180 mm reel), enabling automated optical inspection and traceability in SMT assembly lines.
