Product details
Overview
BAS70B5000 from Infineon Technologies is a silicon Schottky diode in SOT23 package configured as a single diode, rated for 70 V reverse voltage, 70 mA forward current, and 250 mW power dissipation, with typical forward voltage of 600 mV at 10 mA - used for high-speed switching and voltage clamping in signal conditioning circuits.
For engineers reviewing the BAS70B5000 datasheet, BAS70B5000 pinout, BAS70B5000 application, or BAS70B5000 equivalent, key selection criteria include low forward voltage (≤720 mV max at 15 mA), ultra-low reverse leakage (≤0.1 µA at 50 V), sub-100 ps reverse recovery time, and thermal resistance ≤165 K/W for reliable operation up to 125°C ambient.
Technical Context
This Schottky diode leverages a planar silicon process to achieve low barrier height and minimal minority carrier storage, enabling fast switching (τrr ≤100 ps) and low forward conduction loss. Its SOT23 package provides standardized surface-mount compatibility with verified thermal performance up to TS = 109°C.
The device exhibits stable capacitance (CT = 1.5–2 pF at 0 V, 1 MHz) and low series resistance (rf = 34 Ω typ. at 10 mA, 10 kHz), making it suitable for RF detection, clamping, and high-frequency rectification where parasitic effects must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Reverse Voltage (VR) | 70 V - supports clamping and protection in 48 V and lower DC systems without breakdown |
| Forward Current (IF) | 70 mA continuous - sufficient for signal-level rectification and logic-level clamping |
| Forward Voltage (VF) | 600 mV typ. @ 10 mA - reduces conduction loss and self-heating in low-power analog paths |
| Reverse Leakage (IR) | ≤0.1 µA @ 50 V - ensures minimal signal distortion in high-impedance detector/mixer nodes |
| Reverse Recovery Time (τrr) | ≤100 ps - enables operation beyond 1 GHz in RF envelope detection and sampling applications |
| Thermal Resistance (RthJS) | ≤165 K/W - allows sustained 70 mA operation at board temperatures up to 109°C case temperature |
| Junction Temperature (Tj) | 150 °C - defines absolute maximum operating limit under transient overload conditions |
Pinout & Package
SOT23-3 package with standard pin assignment: Pin 1 = Anode, Pin 2 = Cathode, Pin 3 = Not connected (NC) - thermally optimized for PCB copper pour attachment and consistent reflow profile compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Pin 1 | Anode | Main current entry point; requires low-inductance trace routing for high-frequency switching integrity |
| Pin 2 | Cathode | Current return path and thermal sink connection; tied to ground plane for optimal RthJS |
| Pin 3 | NC (No Connect) | Internally unconnected; must remain floating or grounded per layout guidelines to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| Ultra-fast switching | τrr ≤100 ps enables use in >1 GHz RF detector and sampling circuits without timing skew |
| Low forward voltage matching | ΔVF ≤20 mV across multi-diode variants ensures balanced performance in dual-clamp configurations |
| Enhanced thermal resistance | RthJS ≤165 K/W supports higher ambient operation than standard Schottkys in same footprint |
| Stable capacitance vs. voltage | CT varies only 1.5–2 pF from 0–50 V, critical for predictable RF impedance in mixer bias networks |
Applications
| RF Signal Detection | Logic-Level Clamping |
|---|---|
Use Scenario: Demodulating AM signals in 868 MHz ISM-band receivers using envelope detection. IC Role / Device Role / Timing Role: Schottky diode acting as zero-bias RF detector with minimal junction capacitance and series resistance. Use Value: 1.5 pF CT and 34 Ω rf preserve signal fidelity and sensitivity down to -30 dBm input levels. | Use Scenario: Protecting microcontroller GPIO pins from overvoltage transients during hot-plug USB enumeration. IC Role / Device Role / Timing Role: Clamp diode shunting excess voltage to VCC or GND before ESD reaches sensitive I/O structures. Use Value: 0.1 µA IR at 50 V ensures no measurable leakage into 5 V logic rails during normal operation. |
| High-Speed Switching | DC-DC Feedback Sensing |
Use Scenario: Isolating feedback signals between isolated DC-DC converter stages while maintaining signal integrity. IC Role / Device Role / Timing Role: Fast-switching diode blocking reverse current in optocoupler-coupled error amplifier paths. Use Value: 100 ps τrr prevents false triggering during 500 kHz–1 MHz switching transitions. | Use Scenario: Level-shifting and filtering output voltage sense signals in buck regulator feedback loops. IC Role / Device Role / Timing Role: Low-VF diode providing precision offset compensation and noise rejection in analog feedback paths. Use Value: 600 mV VF typ. introduces known, stable offset that can be calibrated out in closed-loop control. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar Schottky diode applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| NSR0230HT1G | Lower VR (30 V), higher IF (200 mA), slightly higher VF (450 mV typ. @ 10 mA) | Not suitable for 48 V clamping; better for 3.3/5 V rail protection with higher surge tolerance | Select when surge robustness > voltage rating, and board space allows larger thermal pad |
| BAT54C | Same SOT23 package, dual common-cathode configuration, VR = 30 V, VF = 380 mV @ 10 mA | Requires redesign for single-diode use; advantageous where dual-channel clamping is needed | Choose for cost-sensitive dual-clamp designs where 30 V rating is sufficient |
Compared with NSR0230HT1G and BAT54C, BAS70B5000 uniquely balances 70 V standoff, ultra-low leakage, and sub-100 ps speed in a single-diode SOT23 - making it optimal for RF and precision clamping where voltage margin and timing integrity are jointly constrained.

FAQ
Is BAS70B5000 qualified for automotive applications?
No - the datasheet explicitly states "Not for automotive applications" and notes that automotive qualification was ongoing as of the 2006 revision. It lacks AEC-Q101 stress test documentation and is intended for industrial, communications, and consumer equipment only.
What is the meaning of 'B5000' in the part number?
'B5000' denotes the packaging variant: 10,000-piece reel on 180 mm diameter carrier. This distinguishes it from B5003 (3,000-piece reel), and confirms tape-and-reel delivery format compatible with standard SMT pick-and-place feeders.
Can BAS70B5000 replace BAS70-04 or BAS70-05 in circuit design?
Yes, electrically - all share identical electrical specs and SOT23 footprint. However, BAS70B5000 is the single-diode version (like BAS70), whereas BAS70-04/-05 are dual configurations; physical replacement requires verifying pinout alignment and functional equivalence in the target circuit.
Does BAS70B5000 have a built-in ESD protection structure?
No - it is a passive Schottky diode without integrated ESD clamp structures. Its 0.1 µA reverse leakage and 70 V VR provide inherent robustness against moderate transients, but external TVS devices are required for IEC 61000-4-2 compliance.
